Collusion in Silicon Valley: OpenAI, Google, Anthropic, and SpaceXAI sued for agreeing to a pause on AI

Four of the world's leading artificial intelligence companies are facing a federal class-action lawsuit in the Northern District of California, accused of violating U.S. antitrust laws by illegally agreeing to slow their technological advancement.

The lawsuit alleges that the agreement between Anthropic, OpenAI, SpaceXAI, and Google undermines free competition and reduces the actual value users receive for their paid subscriptions.

According to the complaint, the coordination was formalized on September 12, after Anthropic CEO Dario Amodei published an essay urging industry-wide cooperation to slow the pace of development in favor of safety protocols.

Amodei proposed a three-point plan to slow the pace of technological advancement, citing cybersecurity risks.

That same day, the leaders of competing companies—Sam Altman of OpenAI, Elon Musk of SpaceXAI, and Demis Hassabis of Google DeepMind—expressed their support for the initiative. However, the lawsuit emphasizes that antitrust laws prevent rival corporations from agreeing to limit innovation on their own terms.

"Antitrust laws do not allow competitors to decide among themselves that competition is too dangerous," the legal document states.

Attorneys representing users subscribed to platforms such as ChatGPT, Claude, Grok, and Gemini filed the lawsuit.

"AI will quickly spiral out of human control if we allow safety to be governed by private, self-serving agreements among the world's most powerful for-profit tech companies," Nick Rowley, lead attorney for the plaintiffs, said.

Although Amodei acknowledged potential antitrust implications in his initial proposal and suggested that the federal government grant a limited exception or exemption for these discussions, federal courts are already scrutinizing the de facto agreement among industry leaders.
