Apple Stock Tanks 5% After FTC Heat and Siri Delays

Apple had a rough Thursday. Shares plummeted 5%, marking the company's worst single-day drop since April.

The sell-off came from a one-two punch. First, reports surfaced that Siri — Apple's long-struggling voice assistant — is facing yet more development delays. Second, the FTC turned its regulatory gaze toward Apple News, putting the company's news aggregation app under scrutiny.

Neither headline alone would typically rattle investors this hard. But combined, they painted a picture of a company wrestling with execution problems on the AI front while simultaneously drawing unwanted attention from federal regulators.

For a stock that's largely shrugged off bad news in recent years, a 5% single-day hit is notable. It signals Wall Street's patience with Apple's AI ambitions — particularly around Siri — may be wearing thin.
