Meta’s Winning Market Definition in Its Monopoly Case Relied on a Flawed Empirical Assumption
Meta prevailed in its monopoly case against the Federal Trade Commission by showing that the FTC’s market definition of personal social media was too narrow. However, Meta’s argument—and Judge James Boasberg’s ruling—rested on a flawed empirical assumption that confuses how users divert their time to other activities when no longer able to use a Meta platform with true product substitution.
AI Transforms Search in a Way That Could Make Google’s Default Advantage Stronger
Judge Amit Mehta’s remedies for Google’s search monopoly stopped short of banning payments for default search placement, reflecting the hope that generative AI will erode the power of traditional search. Cristian Santesteban argues the opposite: in the AI era of search, defaults may matter more by steering critical data and learning signals from AI-powered search sessions to the most dominant product. This mechanism can potentially compound Google’s advantage.
How FTC v. Meta Reshapes the Debate on Social Media and First Amendment Protections
Mihir Kshirsagar argues that the evidence presented in FTC v.

Google Search’s Exclusivity Payments Must Be Capped
Judge Amit Mehta will shortly provide his remedy to Google’s monopoly in internet search. Fiona Scott Morton and Paul Heidhues argue that the remedy must include a cap on Google’s payments to the mobile phone manufacturers, carriers, and web browsers that propelled its monopoly. Because any outright ban risks harming Google’s current partners in the short term, Judge Mehta should consider pursuing a flexible ban that instead limits the revenue these partners can receive from Google in order to encourage market entry and competition.
