The District of Columbia federal court dismissed the agency’s complaint on Monday. The FTC filed suit against Facebook in December, alleging the firm had “engaged in a systematic strategy … to eliminate threats to its monopoly,” including by buying Instagram and WhatsApp. (The Logic)

Talking point: The agency had suggested the court break off parts of Facebook, including its two app subsidiaries—which it has begun to more closely integrate with its own Messenger service— and require it to seek regulatory signoff for future acquisitions. Facebook’s stock jumped Monday afternoon on news that’s now less likely to happen in the near future, closing up 4.18 per cent. The court said the FTC had failed to properly show that the firm “has monopoly power in the market for Personal Social Networking Services,” suggesting that there aren’t clear definitions of what falls into that category and that the agency hadn’t demonstrated Facebook dominates it. It gave the competition watchdog a chance to amend its complaint, but it’s still a setback for the U.S. government’s broader antitrust campaign against the tech giants.
