The US FTC says it will appeal to revive its case accusing Meta of bolstering an illegal monopoly by acquiring Instagram and WhatsApp; Meta won the case in 2025
The U.S. Federal Trade Commission will file an appeal seeking to revive its case accusing Facebook parent company Meta Platforms …
Context & Ripple Effects
The appeal is the next step after a November 2025 ruling in Meta’s favor, now formalized through the FTC’s notice of appeal. The dispute had already survived an earlier effort to avoid trial, when a judge ruled Meta had to face the agency’s breakup case.
At trial, the FTC framed Instagram and WhatsApp as acquisitions under a “buy-or-bury” strategy and defined a narrow personal-social-networking market. The appeal will test whether that legal and market framing can support the case after the trial-court loss.
First-order effects
- Meta remains able to operate Instagram and WhatsApp while the appeal proceeds; the immediate change is renewed litigation risk rather than a mandated divestiture.
- The FTC must persuade an appellate court that the lower court erred in rejecting its monopoly case, extending a challenge that originated in the agency’s 2020 lawsuit.
Second-order effects
- A revived case would keep historical acquisitions central to Meta’s antitrust exposure, making the company’s integration and competitive-defense arguments more consequential in future proceedings.
- Other large platforms and their advisers will watch how the appeal treats market definition, especially the FTC’s earlier narrow personal-social-networking market theory, because that boundary determines which rivals count as competitive constraints.
Third-order effects
- If appellate courts accept narrower digital-market definitions and allow retrospective acquisition challenges to advance, enforcers could have a more durable route to scrutinize already-completed platform deals; that outcome remains uncertain until the appeal is resolved.
- The case illustrates that platform antitrust enforcement is increasingly shaped by litigation over market boundaries and evidence of competitive alternatives, not simply by the size or age of an acquisition.
The trend: US platform antitrust policy is moving toward longer-running tests of whether past acquisitions can be unwound through narrowly defined digital-market theories.
