Meta Wins FTC Antitrust Trial: Analysis of Regulatory Impact and Market Reaction

Meta Platforms Inc. prevailed in a landmark FTC antitrust trial on November 18, 2025 (EST), when a federal judge ruled that its 2012 acquisition of Instagram and 2014 acquisition of WhatsApp do not violate U.S. antitrust laws [1][2][3]. The decision eliminates the risk of Meta being forced to spin off the two platforms, which are core to its social media ecosystem. Meta stated the ruling “recognizes that Meta faces fierce competition” and reaffirms the value of its products for users and businesses [2]. The FTC has not yet announced whether it will appeal the decision [2].

Meta’s stock (META) showed a muted but mixed reaction on the day of the ruling. The stock closed at $597.69, a 0.72% decline from the previous day’s close, but recovered 1.03% intraday from its opening price [0]. Volume surged to 25.31M shares—53% higher than the previous day—indicating increased investor activity [0]. The Communication Services sector (which includes Meta) was the third-best performing sector with a 0.97% gain [0].

The ruling removes a critical regulatory overhang for Meta, potentially supporting its ad pricing power and strategic flexibility in future acquisitions [1][3]. It also sets a precedent for tech companies facing antitrust scrutiny over past acquisitions, as the judge emphasized the need to prove current or imminent harm (not just historical actions) [2].

Investors reacted positively to the regulatory clarity, as reflected in Meta’s intraday recovery and the strong performance of the Communication Services sector [0][1]. Competitor Snap Inc. (SNAP) also saw a 1.98% gain, suggesting broader optimism for the social media space [4].
