The US FTC files a notice to appeal a November 2025 ruling that found Meta did not hold an illegal monopoly by acquiring Instagram and WhatsApp
The U.S. Federal Trade Commission is seeking to revive its case accusing Facebook parent company Meta Platforms (META.O) of bolstering …
Context & Ripple Effects
The notice advances the FTC’s effort to overturn Meta’s November 2025 courtroom win, after a case that had already survived an earlier ruling requiring Meta to face trial over the Instagram and WhatsApp acquisitions. At trial, the agency framed the dispute around a narrow “personal social networking” market, a definition central to its monopoly argument.
The appeal means the FTC is not accepting the outcome of a case built around its claim that Meta used a “buy-or-bury” acquisition strategy. It keeps the legal status of those past deals under active appellate review rather than changing Meta’s operations immediately.
First-order effects
- The FTC can now pursue appellate review of the ruling that rejected its monopoly case; Meta must continue defending the legality of its Instagram and WhatsApp acquisitions.
- The November ruling remains in force unless an appeal changes it, so the notice itself does not require a breakup or alter Meta’s control of either service.
Second-order effects
- The appeal will further test whether the FTC can define a sufficiently narrow social-networking market and prove that historic acquisitions unlawfully preserved power—questions that shape how platforms assess antitrust exposure.
- Other large platforms and prospective acquisition targets gain a live signal that completed deals can remain subject to lengthy enforcement challenges, even after a trial-level win.
Third-order effects
- If the FTC ultimately succeeds, the case could strengthen merger enforcement aimed at dominant platforms’ past acquisitions; if it fails, it may reinforce the difficulty of unwinding completed tech deals under current monopoly standards.
- The broader issue is whether competition policy can address platform consolidation through retrospective litigation, rather than relying chiefly on review before transactions close.
The trend: This is part of a continuing push to test whether antitrust law can constrain dominant digital platforms through challenges to acquisitions made years earlier.
