The FTC plans to appeal a court ruling that favored Meta in an antitrust case regarding its acquisitions of Instagram and WhatsApp. The FTC argues that Meta has unlawfully maintained a monopoly, harming competition and consumers. The case, which began in December 2020, has seen various legal developments, including a major victory for Meta in November 2025 when a judge ruled the FTC failed to prove Meta's monopoly power. The appeal will be heard by the US Court of Appeals for the District of Columbia.
