    Before BRISCOE, Chief Judge, BALDOCK and HOLMES, Circuit Judges.
    HOLMES, Circuit Judge.
    Petitioner Qwest Corporation (“Qwest”) seeks our review of an order of the
    Federal Communications Commission (“Commission”) denying Qwest’s petition
    for regulatory forbearance pursuant to 
    47 U.S.C. § 160
    (a). Qwest filed a petition
    with the Commission in March 2009 seeking relief from certain regulations
    pertaining to telecommunications services that it provides in the Phoenix,
    Arizona, metropolitan statistical area (“MSA”). The Commission denied the
    petition, citing insufficient evidence of sufficiently robust competition that would
    preclude Qwest from raising prices, unreasonably discriminating, and harming
    consumers. Qwest challenges the Commission’s decision only as it pertains to
    Qwest’s mass-market retail services in the Phoenix MSA. For the reasons set
    forth below, we deny Qwest’s petition.
    I
    In the Telecommunications Act of 1996 (“1996 Act”), Congress upended
    the existing telecommunications regulatory regime and imposed on the
    monopolistic local phone companies (called “local exchange carriers” or “LECs”)
    several new requirements designed to enhance competition in the market for local
    telephone service. See Qwest Corp. v. Colo. Pub. Utils. Comm’n, 
    656 F.3d 1093
    ,
    1096 (10th Cir. 2011). Foremost among these is the requirement that incumbent
    -3-
    carriers share their networks with competitors. Because new market entrants
    would find it prohibitively costly to replicate the infrastructure necessary to
    provide local service, the 1996 Act requires incumbent carriers to provide
    competitors with access to existing network elements on an unbundled basis at
    “just” and “reasonable” rates. See 
    47 U.S.C. § 251
    (c)(3). The Commission is
    responsible for determining which unbundled network elements (“UNEs”) an
    incumbent LEC must make available to competitors. See 
    id.
     § 251(d)(2)(B).
    A second critical feature of the 1996 Act is section 10, codified at 
    47 U.S.C. § 160
    . Because newly competitive conditions could make the
    heavy-handed regulation of incumbent carriers obsolete, section 10 provides that
    the Commission “shall forbear” from applying certain statutory or regulatory
    requirements to an incumbent carrier if it determines that those requirements are
    (1) not necessary to ensure just, reasonable, and nondiscriminatory terms of
    service, (2) not necessary to protect consumers, and (3) consistent with the public
    interest. See 
    47 U.S.C. § 160
    (a). A carrier can petition the Commission for
    forbearance. 
    Id.
     § 160(c). The petition “shall be deemed granted if the
    Commission does not deny the petition for failure to meet the requirements for
    forbearance under subsection (a) . . . within one year.” Id. (emphasis added).
    The Commission may extend that one-year deadline by an additional ninety days.
    See id.
    -4-
    The dispute here arises out of a June 2010 order of the Commission
    denying Qwest’s petition for forbearance from unbundling obligations and
    dominant-carrier regulations pertaining to Qwest’s provision of mass-market
    services in the Phoenix MSA. See In the Matter of Petition of Qwest Corporation
    for Forbearance Pursuant to 
    47 U.S.C. § 160
    (c) in the Phoenix, Arizona
    Metropolitan Statistical Area, 25 FCC Rcd. 8622, 8677, ¶ 109 (2010) [hereinafter
    Phoenix Order]. Before reviewing that order, however, some additional
    background is necessary. In particular, we summarize three prior orders of the
    Commission that provide a central backdrop to the issues in this appeal. After
    providing key background information, we describe the Phoenix Order and the
    Commission’s reasons for denying forbearance to Qwest.
    A
    In 2004, Qwest filed a petition for forbearance from unbundling
    requirements and dominant-carrier regulations in the MSA of Omaha, Nebraska,
    where it competes extensively with Cox Communications, a cable provider. In
    response to the petition, the Commission found that “sufficient facilities-based
    competition . . . exists in certain of Qwest’s Omaha MSA wire center service
    areas to justify forbearance.” In the Matter of Petition of Qwest Corporation for
    Forbearance Pursuant to 
    47 U.S.C. § 160
    (c) in the Omaha Metropolitan
    Statistical Area, 20 FCC Rcd. 19,415, 19,447, ¶ 64 (2005) [hereinafter Omaha
    Order]. To reach this conclusion, the Commission essentially applied a two-
    -5-
    prong test. Under the first prong (the “market-share test”), the Commission
    assessed the level of retail competition in the Omaha market and found it
    “compelling” that Qwest’s market share for retail mass-market customers was
    “less than” a specified percentage. 1 
    Id. at 19,430, ¶ 28
    ; see also 
    id. at 19,448, ¶ 66
    . Under the second prong (the “coverage test”), the Commission considered
    the geographic reach of Cox’s cable network and found that, in certain locations
    called “wire centers,” Cox had deployed facilities capable of reaching a very
    significant percentage of end-users. See 
    id. at 19,446, ¶ 62
    . Concluding that Cox
    could successfully compete with Qwest, the Commission granted forbearance to
    Qwest with respect to those wire centers. See 
    id. at 19,447, ¶ 64
    .
    Then, in 2006, Verizon Telephone Companies (“Verizon”) sought
    regulatory forbearance in six MSAs where it provided services as an incumbent
    carrier. The Commission denied Verizon’s petition, finding insufficient evidence
    of facilities-based competition. See In the Matter of Petitions of the Verizon
    Telephone Companies for Forbearance Pursuant to 
    47 U.S.C. § 160
    (c) in the
    Boston, New York, Philadelphia, Pittsburgh, Providence and Virginia Beach
    1
    Some documents relevant to our disposition of this case contain
    competitively sensitive information (e.g., certain market-share data) that is the
    subject of FCC protective orders and not available in publicly accessible
    materials. In the publicly accessible versions of these documents, this sensitive
    information has been redacted. Although we have been furnished access to this
    sensitive information by the parties in sealed filings, we cite in this opinion to
    materials that do not contain this information—having no need to do otherwise,
    and to facilitate public access. Consequently, in some instances we do not supply
    precise figures, as they are redacted in the publicly accessible documents.
    -6-
    Metropolitan Statistical Areas, 22 FCC Rcd. 21,293, 21,313, ¶ 37 (2007)
    [hereinafter Verizon Six-MSA Order]. Specifically, the Commission stated,
    “Overall, in all of the 6 MSAs, it appears that cable operators are presently
    making some competitive gains against Verizon by providing voice service to
    consumers in the residential markets, however competition from cable operators
    does not yet present a sufficient basis for relief.” 
    Id. at 21
    ,314 n.116. In
    assessing Verizon’s market share in a given MSA, the Commission looked to the
    number of Verizon customers as a percentage of both the total number of
    customers who subscribed to landline (“wireline”) service in the MSA and the
    total number of customers who subscribed exclusively to mobile wireless
    service—viz., customers who had “cut the cord.” See 
    id. at 21,323
    , App. B; see
    also 
    id. at 21
    ,308 n.89, ¶ 27 (“[B]ased on the record here, and consistent with
    recent precedent, we include [in market-share computations] cut-the-cord wireless
    substitution.”). Estimates for the latter group of customers were not available on
    an MSA-specific basis, so the Commission utilized a national estimate and
    “assume[d]” that 12.8% of households in a given MSA had cut the cord. 
    Id. at 21,323
    , App. B.
    In 2007, Qwest sought regulatory forbearance in four MSAs, including
    Phoenix. The Commission acknowledged that the coverage test articulated in the
    Omaha Order was met because Cox, Qwest’s primary competitor in Phoenix, was
    capable of reaching at least seventy-five percent of end-users with its own
    -7-
    facilities. See In the Matter of Petitions of Qwest Corporation for Forbearance
    Pursuant to 
    47 U.S.C. § 160
    (c) in the Denver, Minneapolis-St. Paul, Phoenix, and
    Seattle Metropolitan Statistical Areas, 23 FCC Rcd. 11,729, 11,754, ¶ 35 & n.127
    (2008) [hereinafter Qwest Four-MSA Order]. Focusing on the market-share test,
    the Commission opined:
    In calculating market shares, we believe it is appropriate to
    include wireless-only households (i.e., residential telephone
    customers who have “cut the cord”). In particular, we find that
    mobile wireless service should be included in the local services
    product market to the extent that it is used as a complete
    substitute for all of a consumer’s voice communications needs.
    Over the past several years, as wireless substitution rates have
    continued to rise, the Commission has begun including such
    intermodal substitution in its competitive analyses of the local
    services market.
    
    Id. at 11,742, ¶ 19
     (footnote omitted).
    The Commission nevertheless found that Qwest did not meet the market-
    share test. The Commission noted that it had previously sought to determine
    whether carriers have “a retail market share of less than 50 percent.” 
    Id. at 11750, ¶ 28
    . In particular, the Commission found fault with the geographic scope and
    the reliability of Qwest’s market-share data. In this regard, the Commission
    declined to rely on “national wireless-only household data published by the
    Center for Disease Control (CDC) or the more localized information,” 
    id. at 11,743, ¶ 21
    , which the Commission considered to be uninformative and
    unreliable, see 
    id. at 11
    ,744–45, ¶ 21. In sum, the Commission stated, “Qwest
    -8-
    seeks regulatory relief for particular MSAs based on the specific competitive
    conditions in those markets, but the CDC estimates and the record generally do
    not contain reliable data of this type.” 
    Id. at 11,744, ¶ 21
    . More specifically, the
    Commission concluded:
    Qwest has not sufficiently supported its case for forbearance on
    the basis of reliable, geographically-specific data regarding the
    measure of wireless substitution in the four MSAs. . . . We
    emphasize that petitioners relying on mobile wireless substitution
    to support forbearance relief should submit complete and reliable
    data that is geographically specific to the areas for which
    forbearance is sought.
    
    Id. at 11,745, ¶ 22
    . Because reliable Phoenix-specific data was not available in
    the record, the Commission calculated Qwest’s market share without accounting
    for cut-the-cord customers and denied the request for forbearance. See 
    id.
    Verizon, and then Qwest, appealed the Commission’s orders to the D.C.
    Circuit. That court stayed Qwest’s appeal and heard Verizon’s challenge first.
    Verizon argued that the Commission’s exclusive reliance on existing market share
    to deny forbearance was arbitrary and capricious, and the D.C. Circuit agreed.
    See Verizon Tel. Cos. v. FCC, 
    570 F.3d 294
    , 302 (D.C. Cir. 2009). The court
    noted that the Commission had “zeroed in on Verizon’s market share as the
    dispositive factor in its . . . analysis.” 
    Id. at 301
    . However, in previous orders,
    including the Omaha Order, the Commission had considered both actual
    competition (as represented by existing market share) and the potential for
    competition from other carriers. See 
    id.
     at 303–04. The court concluded that the
    -9-
    “per se market share test” applied in the Verizon Six-MSA Order marked an
    “unexplained departure from [the Commission’s] precedent.” 
    Id. at 296
    . The
    court remanded the order, directing the Commission either to consider factors
    other than a market-share benchmark or to “justify its departure from . . .
    precedent.” 
    Id. at 305
    . Because the Qwest Four-MSA Order employed a similar
    analytical approach, the Commission sought and was granted a voluntary remand
    of that order. Order, Qwest Corp. v. FCC, No. 08-1257 (D.C. Cir. Aug. 5, 2009).
    B
    Following remand of the two orders, in March 2009, Qwest filed a petition
    for forbearance specific to the Phoenix MSA. In particular, it sought to explain
    its low and dwindling retail market share in the Phoenix MSA by providing the
    Commission with Phoenix-specific cut-the-cord data. See Joint App. at 261–65
    (Petition of Qwest Corp. for Forbearance Pursuant to 
    47 U.S.C. § 160
    (c), dated
    Mar. 24, 2009). Qwest acknowledged that, in the Qwest Four-MSA Order, the
    Commission had rejected its forbearance request in part because of its “lack of
    Phoenix-specific wireless substitution data that the Commission deemed reliable.”
    
    Id. at 245
    . “To address concerns raised by the Commission as to the reliability
    and generality of its wireless substitution study,” Qwest retained a consulting firm
    “to determine the penetration of wireless-only households in the Phoenix MSA.”
    
    Id. at 261
    .
    - 10 -
    Qwest said that its data indicated that Qwest’s market share, taking cord-
    cutting into account, was “substantially less than the 50% market share figure the
    Commission has previously relied upon.” 
    Id. at 246
    ; see 
    id. at 262
     (noting that
    “25 percent of surveyed Phoenix households reported that they are relying upon
    wireless services for all of their communication needs”). Highlighting that it
    previously had demonstrated in the Qwest Four-MSA Order proceeding that Cox’s
    facilities-based coverage in certain areas of Phoenix surpassed seventy-five
    percent, Qwest noted “publicly available information” indicated that “Cox
    currently appears to offer voice services even more widely in Phoenix” than
    Qwest had shown earlier. 
    Id.
     at 246–47. Thus, Qwest believed it qualified for
    forbearance. Significantly, Qwest expressly noted that “[t]he analysis of
    competition in [its] Petition is designed to be consistent with the analytical
    framework applied by the Commission in Qwest’s earlier request for forbearance
    in the Omaha MSA, as well as the analysis applied in the subsequent Verizon Six
    MSA and Qwest 4 MSA proceedings.” 
    Id.
     at 245–46 (footnotes omitted).
    However, at that time, the Commission was reconsidering its analytical
    framework for forbearance petitions. In August 2009, it sought comments on the
    analytical approach that it should employ in resolving the forbearance issues
    presented in the remanded orders. In particular, it sought input regarding whether
    it should “depart from its recent precedent regarding marketplace analysis in
    forbearance petitions,” and concerning the kinds of evidence beyond “market
    - 11 -
    share for a particular product market” that are relevant in determining “whether
    forbearance from unbundling regulations is warranted.” Wireline Competition
    Bureau Seeks Comment on Remands of Verizon 6 MSA Forbearance Order and
    Qwest 4 MSA Forbearance Order, 24 FCC Rcd. 10,881, 10,883 (2009)
    [hereinafter Remand Comment Request].
    Most significantly, in April 2010, the Commission also issued a public
    notice requesting additional comments and data specifically related to Qwest’s
    request for forbearance in the Phoenix MSA. See Joint App. at 1198 (Request for
    Additional Comment and Data Related to Qwest Corporation’s Petition for
    Forbearance, dated Apr. 15, 2010). The notice stated that a number of
    commenters had urged the Commission to analyze Qwest’s petition in light of
    “basic principles of competition policy and the [Federal Trade Commission-
    Department of Justice] Horizontal Merger Guidelines” and to “examine Qwest’s
    market power in discrete product and geographic markets under the standards of
    the FTC-DOJ Horizontal Merger Guidelines and the similar market power
    analysis that the Commission has conducted in recent merger decisions.” 
    Id.
    (quoting Opposition of Integra Telecom, Inc., WC Docket No. 09-135, at 2 (filed
    Sep. 21, 2009)) (internal quotation marks omitted).
    The Commission specifically noted its interest in determining the proper
    analytical approach toward the cut-the-cord phenomenon, seeking comment on
    “whether, for mass market consumers, mobile wireless service is in the same
    - 12 -
    relevant product market as wireline telephone service.” 
    Id. at 1199
    . The
    Commission observed, “A key element of the [FTC-DOJ Horizontal Merger]
    Guidelines, as they relate to product market definition, includes an inquiry into
    whether a hypothetical monopoly provider of a service [i.e., wireline voice
    service] profitably could impose a ‘small but significant and nontransitory’
    increase in the price of such service.” 
    Id.
     and 1199 n.4. (quoting U.S. Dep’t of
    Justice & Fed. Trade Comm’n, Horizontal Merger Guidelines §§ 1.11, 1.12 (Apr.
    2, 1992, revised Apr. 8, 1997), available at
    http://www.justice.gov/atr/public/guidelines/hmg.htm). “We ask Qwest and other
    interested persons,” the notice concluded, “to cite specific evidence in the record
    or provide new data as needed to support their pleadings in response to these
    issues.” Id. (emphasis added).
    Two months later, in June 2010, the Commission denied Qwest’s
    forbearance request. See Phoenix Order, 25 FCC Rcd. at 8677, ¶ 109. The
    Commission began by repudiating the test it had articulated in the Omaha Order,
    finding that test “problematic” and “not adequately justified as a matter of
    economics.” Id. at 8633–34, ¶¶ 24, 26. It explained that the first prong, the
    market-share test, was unduly narrow in focus and inadequate for assessing a
    carrier’s market power—i.e., its ability to maintain prices above competitive
    levels. See id. at 8635, ¶ 28. The second prong of the test—the extent of
    facilities-based coverage by a single competitor such as Cox—“inappropriately
    - 13 -
    assumed that a duopoly always constitutes effective competition.” 2 Id. at
    8635–36, ¶ 29. The Commission explained that duopolies pose “significant risks
    of collusion and supracompetitive pricing” that are inconsistent with consumer
    welfare. Id. at 8636, ¶ 29.
    The Commission also found that real-world developments in the Omaha
    market following its grant there of forbearance were not consistent with
    predictions it had made in the Omaha Order. See id. at 8639–41, ¶ 34. For
    example, the Omaha Order predicted that Qwest and other providers in the area
    would continue to offer wholesale services at competitive prices despite
    elimination of the requirement that Qwest share some of its UNEs. See id. at
    8640, ¶ 34. However, the record showed that competition in Omaha had actually
    decreased since the order was issued: McLeod USA, “the only other competitor of
    significant size” in the Omaha area, had significantly curtailed its operations
    there, and Integra, which had been contemplating entry into the Omaha market,
    had abandoned its plans to do so after issuance of the order. Id. at 8640–41, ¶ 34.
    “With the benefit of hindsight and upon further consideration,” id. at 8633,
    ¶ 24, the Commission decided to adopt “a more comprehensive analytical
    framework” to evaluate the state of competition in telecommunications markets,
    id. at 8642, ¶ 37. As the April 2010 public notice had hinted, the Commission
    2
    A “duopoly” has been defined as “[a] market in which there are only
    two sellers of a product.” Black’s Law Dictionary 577 (9th ed. 2009).
    - 14 -
    “return[ed] to a traditional market power framework,” an analytical approach
    employed in earlier proceedings and embodied in the FTC-DOJ Horizontal
    Merger Guidelines. Id. As the Commission explained it, a market-power analysis
    begins by delineating the relevant product and geographic markets and identifying
    market participants, then examines market-share data, and finally considers
    whether the potential for competitive market entry is sufficient to constrain an
    incumbent carrier’s ability to maintain prices above competitive levels. See id. at
    8646–47, ¶ 42. The Commission found that this analysis was consistent with
    approaches used by other U.S. and foreign regulators; was “better suited” for
    analyzing competitive conditions in a given market; was more consistent with the
    letter and spirit of section 10; and adequately accounted for both actual and
    potential competition. Id. at 8642–44, ¶¶ 37–38.
    With its new framework in place, the Commission proceeded to analyze
    Qwest’s petition. As relevant to this appeal, 3 the Commission began by defining
    the relevant product market for Qwest’s mass-market retail services. Id. at 8649,
    ¶ 51. This included traditional wireline service, as well as facilities-based (but
    not over-the-top) VoIP services. 4 Id. at 8650, ¶¶ 53–54.
    3
    Qwest has challenged only that portion of the Phoenix Order
    pertaining to mass-market retail services. Qwest Opening Br. at 4 n.1.
    4
    Facilities-based voice-over-Internet-protocol (“VoIP”) services are
    voice services offered by cable providers over their own networks. By contrast,
    over-the-top VoIP providers such as Vonage do not operate their own networks
    (continued...)
    - 15 -
    The Commission then discussed whether to include mobile wireless
    services in the product market. Id. at 8651, ¶ 55. Under the new market-power
    framework, inclusion depended on whether the Phoenix residents’ increasing use
    of wireless services “materially constrain[ed] the price of residential wireline
    voice service[s].” Id. The Commission elaborated on this point:
    These two services should be in the same relevant market only if
    the prospect of buyer substitution to mobile wireless access
    constrains the price of wireline access. The first question before
    us then is whether a hypothetical profit-maximizing firm that was
    the only present and future seller of wireline local access services
    could profitably impose a small but significant and nontransitory
    increase in price (SSNIP). In other words, we consider whether
    there are a sufficient number of wireline service customers who,
    in response to a price increase in wireline local access service,
    would stop subscribing to their wireline service and instead rely
    exclusively on mobile wireless service, so as to render the price
    increase unprofitable.
    Id. at 8651–52, ¶ 56 (footnote omitted).
    The Commission averred that the issue was “complicated” and “one that is
    evolving over time.” Id. at 8651, ¶ 55. On the one hand, the Commission
    observed that “[t]he increasing percentage of residential customers that rely solely
    on mobile wireless voice service suggests that an increasing percentage of voice
    4
    (...continued)
    and instead require customers to obtain access from an incumbent carrier such as
    Qwest. See Phoenix Order, 25 FCC Rcd. at 8650 n.163, ¶ 54. The Commission
    has traditionally viewed facilities-based VoIP services as “sufficiently close
    substitutes for local service to include them in the relevant product market.” Id.
    at 8650, ¶ 54. It has traditionally not viewed over-the-top VoIP the same way.
    See id. at 8650, ¶ 54 & n.163.
    - 16 -
    customers view wireless and wireline services as close substitutes,” thus
    “increasing the likelihood” that wireless services “may materially constrain the
    price of residential wireline voice service” and belong in the same product market
    as wireline services. Id. On the other hand, it noted that “the Commission, the
    DOJ, and foreign regulators have previously found that mobile wireless service
    does not constrain the price of wireline service.” Id. at 8652, ¶ 57.
    Ultimately, the Commission determined that the record before it did not
    allow it to make a finding “for purposes of Qwest’s forbearance request” that
    wireless voice services have a material price-constraining effect with respect to
    wireline voice services. Id. at 8651, ¶ 55. The Commission elaborated on the
    point and, significantly, identified certain deficiencies in Qwest’s evidentiary
    showing:
    [N]either Qwest nor any other commenter has submitted evidence
    that would support a conclusion that mobile wireless service
    constrains the price of wireline service. For example, Qwest has
    produced no econometric analyses that estimate the cross-
    elasticity of demand between mobile wireless and wireline access
    services.[ 5] Nor has it produced any evidence that it has reduced
    5
    The economic concept of elasticity of demand—more specifically,
    cross-elasticity of demand—is relevant in determining the appropriate scope of a
    product market. See, e.g., Brown Shoe Co. v. United States, 
    370 U.S. 294
    , 325
    (1962) (“The outer boundaries of a product market are determined by the
    reasonable interchangeability of use or the cross-elasticity of demand between the
    product itself and substitutes for it.”); United States v. Archer-Daniels-Midland
    Co., 
    866 F.2d 242
    , 246 (8th Cir. 1988) (“The boundaries of the product market of
    a particular product can be determined by the reasonable interchangeability or
    cross-elasticity of demand between itself and possible substitutes for it.”). We

    prices for its wireline services or otherwise adjusted its
    marketing for wireline service in response to changes in the price
    of mobile wireless service. Nor has it produced any marketing
    studies that show the extent to which consumers view wireless
    and wireline access services as close substitutes.
    
    Id.
     at 8653–54, ¶ 58 (footnotes omitted). The Commission noted that, although
    Qwest had provided evidence concerning the percentage of households in the
    Phoenix area that depend exclusively on mobile wireless services, that “cannot
    alone establish whether mobile wireless services should be included in the same
    relevant product market as residential wireline voice service.” 
    Id. at 8654, ¶ 59
    .
    Notably, the Commission observed, “Knowing the percentage of households that
    rely exclusively upon mobile wireless is insufficient to determine whether mobile
    5
    (...continued)
    have had occasion to discuss the concept in a helpful manner: “The basic relevant
    product market test is ‘reasonable interchangeability.’ Interchangeability may be
    measured by, and is substantially synonymous with, cross-elasticity. A market is
    elastic if demand goes down as price goes up. A market is cross-elastic if rising
    prices for product A cause consumers to switch to product B.” Telecor

    ,
    1221 (10th Cir. 1986) (“Defining the relevant market first requires a
    determination of the product market. This inquiry necessitates an examination of
    which commodities are ‘reasonably interchangeable by consumers for the same

    al. eds., 3d ed. 2009) (defining “cross-price elasticity of demand” as the “[t]he
    ratio between the proportional change in demand for a good and the proportional
    change in the price of a different good” (emphases added)). Generally speaking,
    as relevant here, the Commission was inquiring into the extent to which the
    demand for access to wireless voice services would increase in response to an
    increase in the price of wireline voice services.
    - 18 -
    wireless services have a price-constraining effect on wireline access services.”
    
    Id.
     In this regard, it stated that “while . . . the number of customers that rely
    solely on mobile wireless service has been growing steadily, we find that other
    reasons may explain the growth in the number of wireless-only customers, besides
    an increasing cross-elasticity of demand between mobile wireless and wireline
    services.” 
    Id.
    Thus, the Commission excluded mobile wireless services from its analysis.
    See id. at 8655, ¶ 60. It noted, however, that it was “mak[ing] no affirmative
    finding that mobile wireless services do not currently, or may not soon, belong in
    the same product market as residential wireline voice services.” Id. It also
    “acknowledge[d] . . . that more consumers may view mobile wireless as a closer
    substitute for wireline voice service than in the past.” Id. However, in the
    Commission’s view, there was “insufficient data in the record to make such a
    determination here.” Id.
    Having excluded mobile wireless services, the Commission identified the
    market participants in the Phoenix area as Qwest, Cox, and various smaller
    competitors that relied predominantly, if not exclusively, on Qwest facilities. Id.
    at 8657, ¶¶ 64–67. It found that retail mass-market services in the region were
    “highly concentrated with two dominant providers, Qwest and Cox.” Id. at 8664,
    ¶ 80. That duopolistic structure, with the potential for tacit price coordination,
    necessitated an inquiry into whether any other competitors in the Phoenix MSA
    - 19 -
    had deployed or could deploy their own facilities to any significant degree and
    also into the potential for de novo entry by new competitors. See id. at 8665–67,
    ¶¶ 82–84. On both fronts, the Commission found competition in the area
    insufficiently robust to put downward pressure on Qwest’s prices. See id. at
    8667–68, ¶ 86.
    That finding formed the basis for the Commission’s conclusion that
    regulatory requirements, particularly unbundling, remained necessary for
    continued assurance of “just, reasonable, and non-discriminatory” terms of
    service. See id. at 8673, ¶ 98. The Commission also held that these requirements
    “remain[ed] necessary to protect consumers,” id. at 8674, ¶ 101, and that
    forbearance was not in the public interest because it would not “promote
    competitive market conditions,” id. at 8675, ¶ 104 (quoting 
    47 U.S.C. § 160
    (b))
    (internal quotation marks omitted). The Commission denied forbearance.
    Qwest now challenges that decision in its petition for review.

    - 22 -
    Qwest challenges the Commission’s Phoenix Order on two grounds. First,
    it argues that section 10 requires the Commission to make affirmative findings on
    the substantive prerequisites for granting forbearance; that the Commission here
    made no such affirmative findings; and, therefore, that the request for forbearance
    should be “deemed granted” by operation of law. Second, Qwest argues that the
    Commission’s decision was irrational. We reject both contentions. We conclude
    that the Phoenix Order was a reasoned and reasonable decision.
    1
    With respect to a petition for forbearance, section 10(c) of the 1996 Act
    provides as follows:
    Any such petition shall be deemed granted if the Commission
    does not deny the petition for failure to meet the requirements for
    forbearance under subsection (a) of this section within one year
    after the Commission receives it . . . . The Commission may
    grant or deny a petition in whole or in part and shall explain its
    decision in writing.
    
    47 U.S.C. § 160
    (c).
    Qwest reads this provision as a “default rule”—a “statutory thumb on the
    scale in favor of forbearance”—and argues that the Phoenix Order was
    tantamount to a default triggering a “deemed grant[]” of forbearance because the
    Commission did not affirmatively deny Qwest’s petition on the merits. Qwest
    Opening Br. at 29–30. In Qwest’s view, it “met all preexisting standards for
    forbearance,” and the Commission denied its petition, not because it failed to
    - 23 -
    meet those standards, but because the Commission “wished to suspend judgment
    on whether those standards are in fact the right ones.” 
    Id. at 28
    . Qwest argues
    that “the legal consequence of such bureaucratic indecision is to ‘deem[]’ the
    petition ‘granted’ by operation of law.” 
    Id. at 29
     (quoting 
    47 U.S.C. § 160
    (c)).
    The Commission counters that Qwest is improperly attempting to reverse
    the burden of proof in forbearance proceedings. See Aplee. Br. at 28–29. In the
    Commission’s view, section 10(c) does not make forbearance the “default,” and it
    does not put the onus on the Commission to prove that the prerequisites for
    forbearance are not satisfied. Rather, section 10(c) “simply means” that the
    Commission must attend promptly to forbearance petitions, and the burden is on
    the petitioner to show that a regulatory obligation is not needed and that
    forbearance is consonant with the public interest. 
    Id.
     at 29–30 (citing 
    47 U.S.C. § 160
    (a)(1)–(3)). The Commission says that Qwest failed to meet that burden here
    and the Phoenix Order so concluded. See 
    id.
     at 32–33.
    We first address the issue of burden of proof. Although the statute says
    nothing about it, the Commission has determined through a notice-and-comment
    proceeding that the burden of proof—encompassing the burdens of both
    production and persuasion—is on the petitioner. See In the Matter of Petition to
    Establish Procedural Requirements to Govern Proceedings for Forbearance
    Under Section 10 of the Communications Act of 1934, As Amended, 24 FCC Rcd.
    9543, 9554–55, ¶ 20 (2009) [hereinafter Forbearance Procedures Order]. That
    - 24 -
    construction of section 10(c) is entitled to our deference. See Mead Corp., 
    533 U.S. at 230
     (holding that agency interpretations promulgated by notice-and-
    comment rulemaking warrant Chevron deference). And we believe the
    construction to be a reasonable one. See Schaffer ex rel. Schaffer v. Weast, 
    546 U.S. 49
    , 57 (2005) (concluding that, where a statute was silent on the burden of
    persuasion and “[a]bsent some reason to believe that Congress intended
    otherwise,” the burden “lies where it usually falls, upon the party seeking relief”);
    see also Zhang v. Slattery, 
    55 F.3d 732
    , 756 (2d Cir. 1995) (holding that in the
    absence of an express statutory allocation of the burden of proof, the Board of
    Immigration Appeals’s placement of the burden on the alien was reasonable under
    Chevron), superseded by statute on other grounds, 
    8 U.S.C. § 1101
    (a)(42);
    Panhandle Producers & Royalty Owners Ass’n v. Econ. Regulatory Admin., 
    847 F.2d 1168
    , 1175–76 (5th Cir. 1988) (holding that an agency’s policy shift,
    reallocating the burden of proof from natural gas importers to parties opposing
    importation, “was based on a reasonable interpretation of the Natural Gas Act”).
    Even so, a plain reading of section 10 makes clear that the Commission has
    obligations of its own when a party petitions for forbearance. To avoid a
    “deemed grant[]” of forbearance, the Commission must: (1) deny a petition “for
    failure to meet the requirements for forbearance” under section 10(a), (2) explain
    its decision in writing, and (3) do so within the statutorily prescribed period (i.e.,
    one year, with a possible extension of up to ninety days). 
    47 U.S.C. § 160
    (c)
    - 25 -
    (emphasis added). That is, the Commission must, within the statutorily
    prescribed period, affirmatively find that at least one of the substantive
    prerequisites for forbearance is not satisfied—for example, that enforcement
    remains necessary to ensure just, reasonable, and nondiscriminatory terms of
    service, 
    id.
     § 160(a)(1); that enforcement remains necessary to protect consumers,
    id. § 160(a)(2); or that forbearance would not be consistent with the public
    interest, id. § 160(a)(3)—and offer a written explanation to that effect. The
    Commission need only find that one of the prerequisites for forbearance is not
    met to justify denying the petition. See Cellular Telecomms. & Internet Ass’n v.
    FCC, 
    330 F.3d 502
    , 509 (D.C. Cir. 2003) (“The three prongs of § 10(a) are
    conjunctive. The Commission could properly deny a petition for forbearance if it
    finds that any one of the three prongs is unsatisfied.”). But at least one such
    finding is necessary for a proper denial and to avoid a “deemed grant[].”
    Qwest argues that the Commission dropped the ball here; that the Phoenix
    Order “fail[ed] to make the requisite statutory findings” under section 10(a); and
    that we should therefore “deem[]” Qwest’s petition “granted.” Qwest Opening
    Br. at 30. We are not persuaded. In the Phoenix Order, the Commission
    explicitly found that maintaining Qwest’s unbundling obligations was necessary
    both for continued assurance of just, reasonable, and nondiscriminatory terms of
    service and for protection of Phoenix consumers, see 22 FCC Rcd. at 8673–74,
    ¶¶ 98, 101 (citing 
    47 U.S.C. §§ 160
    (a)(1), (a)(2)), and that forbearance would not
    - 26 -
    be consistent with the public interest, see 
    id. at 8675
    , ¶ 105 (citing 
    47 U.S.C. § 160
    (a)(3)). Moreover, as we explain below, the Commission adequately
    justified those conclusions, both on the merits and in light of the conscious policy
    shift it was making.
    Qwest attempts to frame the Phoenix Order as doing nothing more than
    expressing the Commission’s “uncertainty” about its prior forbearance standards
    and “thank[ing]” Qwest for its submission. Qwest Opening Br. at 29–30. We
    need not opine on whether that kind of order would trigger a “deemed grant[]”
    under section 10(c) because we disagree with Qwest’s characterization. In our
    view, the Commission rendered a reasoned decision on the merits of Qwest’s
    petition in writing and within the statutorily prescribed time frame. To be sure, as
    we explicate further below, the Phoenix Order altered precisely how the merits of
    forbearance petitions are assessed, and it might well be true (though we need not
    say) that Qwest “met all preexisting standards for forbearance.” 
    Id. at 28
    (emphasis added). But we decline to hold that a forbearance petition is “deemed
    granted” under section 10(c) whenever the Commission embarks upon a policy
    shift—at least when, as here, we cannot conclude that the Commission’s policy
    shift was arbitrary or capricious.
    We hold that the Commission met its procedural obligations under section
    10 in denying Qwest’s forbearance petition. In other words, the petition was not
    “deemed granted” through some procedural omission of the Commission.
    - 27 -
    Accordingly, we proceed to Qwest’s merits-based challenges to the Phoenix
    Order.
    2
    Qwest attacks the Phoenix Order as irrational, arguing that the Commission
    “ignored” the cut-the-cord phenomenon, contrary to its own precedent, and that
    the Commission’s assessment of competitive conditions in the Phoenix market
    was unreasonable. We reject both arguments and conclude that the Commission’s
    decision was not “arbitrary, capricious, an abuse of discretion, or otherwise not in
    accordance with the law.” Sorenson II, 
    659 F.3d at 1045
     (quoting 
    5 U.S.C. § 706
    (2)(A)) (internal quotation marks omitted).
    a
    We begin with Qwest’s arguments concerning the Commission’s treatment
    of the Phoenix-specific cut-the-cord data supplied by Qwest. We acknowledge
    that the Commission engaged in some goalpost-moving on this issue. We
    nevertheless hold that the exclusion of the cut-the-cord data in the Phoenix Order
    was not arbitrary and capricious based on the unique circumstances of this case
    and the Commission’s adequate explanation for its shift to a market-power
    framework.
    In its Verizon Six-MSA Order, the Commission used a national cut-the-cord
    estimate to calculate Verizon’s market share in various MSAs. See 22 FCC Rcd.
    - 28 -
    at 21,323, App. B. It found that Verizon did not satisfy the market-share
    benchmark even including the cut-the-cord data. See 
    id. at 21
    ,307–08, ¶ 27.
    Subsequently, in the Qwest Four-MSA Order, the Commission found that it was
    “appropriate to include wireless-only households” in calculating a carrier’s
    market share and observed that “[o]ver the past several years, as wireless
    substitution rates have continued to rise, the Commission has begun including
    such intermodal substitution in its competitive analyses of the local services
    market.” 23 FCC Rcd. at 11,742, ¶ 19 (citing several past orders). The
    Commission, however, faulted Qwest for relying on national estimates of
    wireless-only households—despite the Commission’s prior reliance on such
    national data in the Verizon Six-MSA Order. It insisted that Qwest provide
    reliable cut-the-cord data related to the Phoenix MSA and noted that the more
    localized data in the record was neither informative nor reliable. The
    Commission noted that “Qwest might have qualified for some forbearance upon a
    better evidentiary showing.” 
    Id. at 11,745, ¶ 22
    . But it went on to “emphasize
    that petitioners relying on mobile wireless substitution to support forbearance
    relief should submit complete and reliable data that is geographically specific to
    the areas for which forbearance is sought.” 
    Id.
    In the Phoenix Order, Qwest delivered precisely the sort of reliable data
    that was lacking in the Qwest Four-MSA Order concerning the percentage of
    wireless-only voice customers in the Phoenix MSA. And the Commission seemed
    - 29 -
    to acknowledge as much. See Phoenix Order, 25 FCC Rcd. at 8,654, ¶ 59 &
    n.178 (noting that “Qwest submitted studies that estimate the percentage of
    households that exclusively rely upon mobile wireless services in the Phoenix
    area” and “acknowledg[ing] that the Commission in the Qwest 4 MSA
    Forbearance Order suggested that geographically disaggregated evidence of the
    percentage of voice subscribers that rely on mobile wireless only might
    demonstrate that Qwest was entitled to forbearance in the Phoenix MSA.”).
    However, the Commission moved the goalpost. It criticized Qwest’s evidentiary
    showing again, this time because Qwest failed to present evidence that consumers
    consider wireline voice services and wireless voice services to be substitutes,
    such that the latter materially constrains the price of the former. Specifically, the
    Commission observed, “Knowing the percentage of households that rely
    exclusively upon mobile wireless is insufficient to determine whether mobile
    wireless services have a price-constraining effect on wireline access services.”
    
    Id. at 8654, ¶ 59
    .
    This kind of goalpost-moving does not reflect an optimal mode of
    administrative decisionmaking. And we do not foreclose the possibility that
    under some circumstances an agency’s shifting of the policy goalpost (e.g., the
    evidentiary requirements for satisfying a particular statutory or regulatory
    standard) may lead us to conclude that the agency has acted arbitrarily or
    capriciously. See Smiley v. CitiBank (South Dakota), N.A., 
    517 U.S. 735
    , 742
    - 30 -

    - 31 -
    However, this is not a case where a conclusion of arbitrary or capricious
    agency action is warranted. Two factors provide the central pillars supporting our
    view: first, the unique factual circumstances surrounding the issuance of the
    Phoenix Order, which should have provided Qwest with at least some (albeit
    limited) notice that a policy shift to a market-power analytical framework might
    be in the offing; and second, the Commission did not ignore the cut-the-cord
    phenomenon, but rather offered a reasonable explanation for why under the
    circumstances of this proceeding wireless voice services were excluded from the
    product market.
    The factual circumstances surrounding the issuance of the Phoenix Order
    are somewhat unusual. Qwest filed the earlier petition associated with the Qwest
    Four-MSA Order while Verizon’s appeal of the Verizon Six-MSA Order was
    pending. Upon review of the Verizon order, the D.C. Circuit disapproved the
    Commission’s unexplained policy shift toward an exclusive reliance upon a
    carrier’s market share, and it remanded the order. See Verizon Tel., 
    570 F.3d at 305
    . In the meantime, the Commission had issued its decision in the Qwest Four-
    MSA Order. Because that order embraced an analytical approach similar to the
    Verizon order, the D.C. Circuit’s decision applied equally to it. That order, too,
    was remanded (at the Commission’s request). Both remands were an opportunity
    for the Commission to reconsider its reasoning in those orders and, more
    generally, its approach to forbearance petitions.
    - 32 -
    The Commission sought comment on the analytical approach that it should
    adopt for the remanded orders. Among other things, the Commission sought input
    regarding whether it should “depart from its recent precedent regarding
    marketplace analysis in forbearance petitions,” and concerning the kinds of
    evidence beyond “market share for a particular product market” that are relevant
    in determining “whether forbearance from unbundling regulations is warranted.”
    Remand Comment Request, 24 FCC Rcd. at 10,883; see also Phoenix Order, 25
    FCC Rcd. at 8632, ¶ 20 (discussing the regulatory history concerning
    forbearance). At the time, Qwest’s Phoenix-MSA petition was pending before the
    Commission.
    Although the request for comments in connection with the remanded orders
    was quite general, the Commission was more specific when it requested
    comments in connection with Qwest’s Phoenix-MSA petition in April 2010.
    There, the Commission indicated that it was reconsidering its analytical approach
    to forbearance petitions; that, specifically, it was pondering adopting a market-
    power approach as reflected in the FTC-DOJ Horizontal Merger Guidelines; that
    “[a] key element of the Guidelines, as they relate to product market definition,
    includes an inquiry into whether a hypothetical monopoly provider of a service
    [e.g., wireline voice service] profitably could impose a ‘small but significant and
    nontransitory’ increase in the price of such service,” Joint App. at 1199 n.4
    (quoting FTC-DOJ Horizontal Merger Guidelines §§ 1.11, 1.12); and the
    - 33 -
    Commission invited Qwest to “cite specific evidence in the record or provide new
    data . . . in response to these issues,” id. at 1199.
    The Commission, to be sure, did not commit to a definite policy shift in the
    April 2010 notice. And this more specific signal that a policy change might be
    coming came pretty late in the day. The notice was issued only a little more than
    two months before the Commission actually issued the Phoenix Order. However,
    the foregoing factual circumstances suggest to us that the Commission did not act
    whimsically or rashly in altering its forbearance policy—the D.C. Circuit remands
    gave the Commission a concrete reason to step back and assess its current policy
    direction—and that the Commission did provide Qwest with some notice (albeit
    of a temporally and substantively limited sort) that a policy move to a market-
    power approach might be in the offing, thus significantly diminishing the reliance
    that Qwest reasonably could have placed on the Commission’s previous policy
    stance. Therefore, we conclude that these unique circumstances counsel against a
    determination that the Commission acted arbitrarily or capriciously in moving the
    policy goalpost. 6
    6
    Indeed, in the Phoenix Order, the Commission expressly referred to
    this unique set of circumstances in justifying its policy shift:
    We acknowledge that the Commission in the Qwest 4 MSA
    Forbearance Order suggested that geographically disaggregated
    evidence of the percentage of voice subscribers that rely on
    mobile wireless only might demonstrate that Qwest was entitled
    to forbearance in the Phoenix MSA. See Qwest 4 MSA
    (continued...)
    - 34 -
    Furthermore, the Commission offered a reasonable explanation for its
    movement to a market-power analytical framework, which necessitated the
    production of qualitatively different evidence to warrant regulatory forbearance.
    As the Commission indicated, the market-power framework necessitated a more
    rigorous inquiry than the Commission had undertaken in prior orders (such as the
    Omaha Order), and part of the inquiry entailed a specific delineation of the
    relevant product market for evaluating competitive conditions in the Phoenix
    MSA. See Phoenix Order, 25 FCC Rcd. at 8646, ¶¶ 41–42. Further, the product-
    market analysis required more than a facile reliance on cut-the-cord percentages.
    See id. at 8654–55, ¶ 59. Rather, under the market-power rubric, the relevant
    question was the degree to which the cut-the-cord phenomenon materially
    constrained the prices that a wireline carrier like Qwest could charge its existing
    customers. Id. at 8651–52, ¶ 56. That in turn required an inquiry, not simply into
    6
    (...continued)
    Forbearance Order, 23 FCC Rcd at 11745, para. 22. Since those
    statements were made, however, the D.C. Circuit remanded the
    Verizon 6 MSA Forbearance Order and instructed the
    Commission to provide a more complete economic analysis of its
    decision to deny forbearance. The D.C. Circuit, at the
    Commission’s request, also remanded the Qwest 4 MSA
    Forbearance Order.        After the remands, the Wireline
    Competition Bureau issued a Public Notice in the present
    proceeding seeking new record data that might show that, under
    a traditional market power analysis, mobile wireless service is in
    the same relevant product market as mass market wireline
    telephone service.

    the number of wireless-only customers, but into the cross-elasticity of demand
    between wireline and wireless services—that is, roughly speaking, the likelihood
    that customers can and will switch between the two forms of service in response
    to price changes. As to that inquiry, the Commission found that Qwest had
    offered no evidence.
    In sum, the Commission offered an extensive discussion of its reasons for
    abandoning the two-part test in the Omaha Order and for adopting the market-
    power approach—an approach with some basis in the Commission’s precedent
    and, in the Commission’s view, better in keeping with the underlying purposes of
    section 10. 7 See id. at 8633–45, ¶¶ 24–40. The Commission, therefore, was
    conscious of the change it was making, believed it to be better, explained why it
    was necessary, and offered a sound basis for repudiating its prior decisions. See
    Fox Television, 
    556 U.S. at
    515–16; cf. Verizon Tel., 
    570 F.3d at 304
     (stating that
    “[t]he flaw” in the Commission’s policy shift was “not in the th[e] change, but
    rather in the [Commission’s] failure to explain it”). No doubt, the Commission
    7
    It also bears mention that Qwest has not challenged the market-power
    approach as inconsistent per se with section 10. Furthermore, because “Congress
    did not prescribe a ‘particular mode of market analysis’ or otherwise dictate how
    the [Commission] must make predictive judgments ‘within [its] field of discretion
    and expertise,’ such as those required under § 10,” Verizon Tel.,

    462 F.3d 1

    (D.C. Cir. 2006)), the Commission’s construction of section 10 is entitled to
    deference, see Chevron, 
    467 U.S. at
    843–44 (“If Congress has explicitly left a gap
    for the agency to fill, . . . [the agency’s] regulations [filling in that gap] are given
    controlling weight unless they are arbitrary, capricious, or manifestly contrary to
    the statute.”).

    did move the goalpost here, but it did so under somewhat unique circumstances
    and it “articulate[d] a satisfactory explanation” for doing so. Fox Television, 
    556 U.S. at 513
     (quoting State Farm, 
    463 U.S. at 43
    ) (internal quotation marks
    omitted). We conclude, therefore, that its decision was not arbitrary or
    capricious. 8
    8
    Qwest vigorously objects that the Commission misapplied antitrust
    concepts by relying on the fact that Qwest had not decreased its prices in the
    Phoenix area in response to the cut-the-cord phenomenon. See Phoenix Order, 25
    FCC Rcd. at 8653, ¶ 58 (noting that Qwest did not “produce[] any evidence that it
    has reduced prices for its wireline services . . . in response to changes in the price
    of mobile wireless service.”). Qwest argues that the Commission’s reliance on
    this observation is unreasonable because Qwest is a regulated entity that cannot
    decrease prices for some customers while maintaining them at current levels for
    others. Qwest suggests that, insofar as the Commission relies on proof of a price
    reduction in making its product-market determination, it erects an unreasonable
    and virtually insurmountable evidentiary hurdle for regulated entities like Qwest.
    However, we do not believe that the Commission has acted unreasonably.
    As noted in text supra, the Commission specifically identified other types of
    proof—besides evidence indicating that Qwest lowered its prices—that Qwest
    could have relied upon to support its position that wireline and wireless voice
    services should be in the same product market: (1) econometric studies that
    “estimate the cross-elasticity of demand between mobile wireless and wireline
    access services”; (2) documentation revealing that Qwest has “adjusted its
    marketing for wireline service in response to changes in the price of mobile
    wireless service”; or (3) “marketing studies that show the extent to which
    consumers view wireless and wireline access services as close substitutes.”
    Phoenix Order, 25 FCC Rcd. at 8653–54, ¶ 58. Thus, the Commission explicitly
    left open the door for Qwest to demonstrate, through various forms of evidence,
    that wireless voice services belong in the same product market as traditional
    wireline voice services. We would expect, therefore, that with persuasive market
    surveys or econometric studies on substitutability, Qwest’s failure to lower its
    prices would not, of itself, be an insurmountable hurdle—viz., standing alone, it
    would not preclude the Commission from concluding that wireless voice services
    should be in the same product market as Qwest’s wireline voice services. Finally,
    (continued...)
    - 37 -
    b
    We turn to Qwest’s second major challenge to the Phoenix Order. Qwest
    assails as unreasonable the Commission’s assessment of competitive conditions in
    the retail mass market in Phoenix, arguing that the Commission unreasonably
    declined to assess competition from wireless companies and unreasonably viewed
    the Phoenix market as an anti-competitive duopoly. We reject Qwest’s
    arguments.
    In the Phoenix Order, after delineating the product market and excluding
    mobile wireless services, the Commission went on to identify the participants in
    the retail mass market in Phoenix. See Phoenix Order, 25 FCC Rcd. at 8657,
    ¶ 67. It found that Qwest faced competition from Cox and a smattering of
    “fringe” competitors that were “able to compete only by relying extensively on
    UNEs and other Qwest wholesale services.” 9 Id. at 8664, ¶ 80 (internal quotation
    marks omitted).
    8
    (...continued)
    we cannot conclude that it is necessarily unreasonable for the Commission to
    consider Qwest’s pricing behavior. See id. at 8653 n.175 (citing a Department of
    Justice study reasoning that an incumbent carrier would lower prices in response
    to customer cord-cutting “if the loss of revenue from cord-cutting is expected to
    be greater than the loss of revenue from reducing the fees paid by customers who
    would not switch”).
    9
    As the Commission explained, “[a] fringe competitor is a small firm
    operating in a market that is dominated by a single firm or a few firms. The
    fringe competitors take the price set by the dominant firm(s) as given and
    maximize their profits given this price.” Phoenix Order, 25 FCC Rcd. at 8664
    n.241, ¶ 80.
    - 38 -
    Qwest faults the Commission for ignoring competition from national
    wireless providers such as AT&T and Verizon Wireless. But the market
    participants that the Commission identified flowed logically from its definition of
    the relevant product market. Because it had determined that the product market
    excluded mobile wireless services—and because that exclusion was not arbitrary
    in this case—it followed that the pool of service providers in the Phoenix MSA
    did not include the national wireless companies. Furthermore, given the market
    dominance of Qwest and Cox in wireline services, it was proper for the
    Commission to treat the Phoenix MSA as effectively a duopoly. See id.
    (observing that “Cox is Qwest’s only competitor that now provides or is soon
    likely to provide retail service to mass market customers over its own last-mile
    network to any significant extent in the Phoenix MSA”). While the Commission
    acknowledged that “under certain conditions duopoly will yield a competitive
    outcome,” id. at 8637, ¶ 30, it observed that “[e]conomists, courts, and the
    Commission have long recognized that duopolies may present significant risks of
    collusion and supracompetitive pricing,” id. at 8636, ¶ 29 (footnotes omitted).
    Qwest counters that the Commission justified this conclusion only by
    reference to antitrust literature concerning “ordinary duopoly markets” and
    ignored the unique characteristics of the telecommunications industry: high fixed
    costs and low marginal costs. Qwest Reply Br. at 24; see Qwest Opening Br. at
    51. Qwest points out that the Commission has found in previous orders that even
    - 39 -
    a single new entrant who has successfully established extensive facilities
    coverage, such as Cox, has “demonstrated a deep commitment to compete
    vigorously for customers,” thus “lessening the need for regulatory intervention.”
    In the Matter of the Petition of ACS of Anchorage, Inc. Pursuant to Section 10 of
    the Communications Act of 1934, As Amended, for Forbearance from Sections
    251(c)(3) and 252(d)(1) in the Anchorage Study Area, 22 FCC Rcd. 1958, 1977,
    ¶ 31 (2007); see also Omaha Order, 20 FCC Rcd. at 19,432, ¶ 33 (“The
    Commission has repeatedly found that residential customers are highly demand-
    elastic, and willing to switch to or from their provider to obtain price reductions
    and desired features.”).
    The Commission had good reasons, however, to call this prior finding into
    question, or at least to question the breadth of its applicability. In explaining why
    the test articulated in the Omaha Order was inadequate, the Commission noted
    that post-forbearance developments in the Omaha market gave it pause. See
    Phoenix Order, 25 FCC Rcd. at 8639–42, ¶¶ 33–36. Among other things,
    competition for retail mass-market services in Omaha declined following the
    Commission’s grant of forbearance to Qwest, even though the Omaha Order
    predicted the contrary outcome. In the Omaha Order, the Commission believed
    that forbearance would not cause Qwest to curtail competitor access to network
    elements. See 20 FCC Rcd. at 19,455, ¶ 81. In the Commission’s view, Cox’s
    aggressive competition would motivate Qwest to offer retail and wholesale
    - 40 -
    services at competitive rates in order to minimize customer defections to Cox’s
    service. See id.
    That prediction, however, did not pan out. As the Commission noted in the
    Phoenix Order:
    [T]he Commission has long recognized that a vertically
    integrated firm with market power in one market--here upstream
    wholesale markets where, as discussed below, Qwest remains
    dominant--may have the incentive and ability to discriminate
    against rivals in downstream retail markets or raise rivals’ costs.
    . . . [T]here is little evidence, either in the record or of which we
    otherwise are aware, that . . . incumbent LECs have voluntarily
    offered wholesale services at competitive prices once regulatory
    requirements governing wholesale prices were eliminated. For
    example, other than Cox, McLeodUSA was the only other
    competitor of significant size cited by the Commission in the
    Qwest Omaha Forbearance Order. The record indicates that
    subsequent to the Qwest Omaha Forbearance Order, Qwest, with
    one exception, was not spurred to offer McLeodUSA any
    wholesale alternatives to UNEs that were not already offered
    prior to the grant of forbearance. Moreover, the record indicates
    that McLeodUSA has removed most of its employees from the
    Omaha marketplace, has limited its operations primarily to
    serving its existing customer base, and has ceased sales of
    residential and nearly all business services in Omaha. This
    suggests that McLeodUSA likewise no longer should be
    considered a significant competitor in the Omaha marketplace.
    We also note record evidence that Integra, which had been
    contemplating entry into the Omaha market, abandoned its plans
    to do so after the Commission issued the Qwest Omaha
    Forbearance Order.
    25 FCC Rcd. at 8640–41, ¶ 34 (footnotes omitted). The Commission
    acknowledged that “multiple factors” could explain this decline and that it was
    “beyond the scope of this proceeding to estimate the extent of competition in
    - 41 -
    Omaha today.” Id. at 8640 n.105, 8641, ¶ 34. However, the Commission was
    entitled to consider this new data as probative of the soundness (or lack thereof)
    of its prior conclusions. See George E. Warren Corp. v. U.S. EPA, 
    159 F.3d 616
    ,
    626–27 (D.C. Cir. 1998) (holding that it was not arbitrary and capricious for an
    agency to change course when “one of its basic assumptions in [earlier]
    rulemaking was contradicted by new data”), amended on other grounds by 
    164 F.3d 676
     (D.C. Cir. 1999).
    Finally, the Commission evaluated whether potential competition in the
    Phoenix MSA could ameliorate the risks of duopolistic price coordination. See
    Phoenix Order, 25 FCC Rcd. at 8666, ¶ 83. It observed that there were no
    competitors for mass-market services in Phoenix that had deployed or could
    deploy their own facilities to any meaningful degree, and that the potential for de
    novo entry by new competitors was limited. See 
    id.
     at 8665–67, ¶¶ 82–84.
    Taking these factors together—specifically, the well-documented anti-
    competitive risks of duopoly, the subsequent developments in Omaha, and the
    lack of effective competition in the Phoenix market—the Commission could
    rationally call into question its earlier predictions, perceive the need for a
    different approach, and proceed cautiously regarding the possibility of granting
    forbearance in the Phoenix MSA, given the real-world understanding that doing
    so might result in a Qwest-Cox duopoly similar to the one in Omaha. Based upon
    - 42 -
    the foregoing reasoning, we reject Qwest’s contention that the Phoenix Order is
    unreasonable.
