FTC appeals Meta antitrust win, keeping pressure on Big Tech dealmaking and platform dominance

The U.S. Federal Trade Commission has appealed a district court ruling that sided with Meta, escalating a marquee antitrust battle over whether the company unlawfully maintained dominance through acquisitions such as Instagram and WhatsApp. The Financial Times reported the appeal follows a November decision by Judge James Boasberg, who concluded the FTC failed to prove Meta currently holds illegal monopoly power or pursued a “buy-or-bury” approach that violated antitrust law.

Regulators argue the case is about more than a single company. It is a referendum on whether U.S. antitrust enforcement can meaningfully respond to platform-era competition, where markets can be shaped by attention, data and network effects rather than traditional pricing power. The FTC’s position has been that buying fast-growing rivals can prevent competition from developing, even if the acquired products later expand under a parent company’s resources.

Meta has countered that the social media market is intensely competitive, pointing to major rivals such as TikTok and YouTube as evidence that users and advertisers have ample alternatives. The prior ruling echoed that view to a degree, emphasizing the evidentiary burden on the government to show monopoly power and the exclusionary conduct needed to justify remedies as severe as unwinding mergers completed years earlier.

The appeal also lands amid a wider wave of U.S. scrutiny of large technology firms, including tough cases that have not always gone regulators’ way in court. Each loss matters because it shapes how agencies draft future complaints, define relevant markets and select the right legal theory to survive judicial skepticism. For companies, the Meta appeal reinforces that even “closed” merger chapters can remain open for years, and that major deals may still face retroactive challenge if regulators believe competition was harmed.

In practical terms, the FTC appeal prolongs uncertainty for Meta and for the broader tech sector’s acquisition playbook. Investors and executives are watching whether the appellate court is willing to revisit questions about how to measure monopoly power in social platforms, and what level of proof is required to show that acquisitions reduced consumer choice, innovation or privacy protections over time.

If the FTC succeeds, the case could become a template for renewed merger challenges across digital markets; if it fails, it may prompt regulators to pursue narrower cases, focus on conduct remedies, or seek legislative changes to update competition rules for the platform economy. Either way, the appeal signals that Washington’s Big Tech crackdown is far from finished. ([ft.com](https://www.ft.com/content/ef7b57cf-d2e7-4cfb-be24-1b5e1bdc3452?utm_source=openai))
