Four AI companies sued for alleged illegal agreement to slow development
A federal lawsuit was filed Friday in California against Anthropic, OpenAI, SpaceXAI, and Google, alleging they violated antitrust laws by coordinating to slow their artificial intelligence development. Four paid subscribers to AI services claim the companies agreed to reduce the pace of capability improvements, which they say reduces the value consumers receive from their subscriptions. The lawsuit centers on September 12, when Anthropic CEO Dario Amodei published an essay calling for industry-wide cooperation to prioritize AI safety over speed. That same day, the CEOs of OpenAI, SpaceXAI, and Google DeepMind publicly agreed with the proposal. The plaintiffs argue that antitrust law prohibits competitors from collectively restraining their own progress, even for safety reasons. Lead attorney Nick Rowley contends that AI safety decisions should be made by government, not private agreements among powerful companies. The defendants have not yet responded to the allegations.
