AI giants Anthropic, OpenAI, SpaceXAI, and Google sued for alleged development slowdown pact

antitrust lawsuit artificial intelligence Sherman Act AI development pace tech industry coordination

A class action lawsuit has been filed in the U.S. District Court for the Northern District of California against Anthropic, OpenAI, SpaceXAI, and Google. The plaintiffs, who are paid subscribers of services including ChatGPT, Claude, Grok, and Gemini, allege that these companies entered into an illegal agreement to coordinate and slow the pace of artificial intelligence development.

The complaint asserts that this coordination violates Section 1 of the Sherman Antitrust Act. Plaintiffs argue that by agreeing to advance their technologies more slowly than natural market competition would dictate, the companies have reduced the value of the paid subscriptions consumers purchase. The lawsuit seeks treble damages and an injunction.

The legal action points to a specific sequence of events, notably an essay published on September 12, 2026, by Anthropic CEO Dario Amodei titled ‘We Must Pace the Frontier,’ which called for industry-wide cooperation to prioritize safety over speed. The lawsuit notes that leaders from OpenAI, SpaceXAI, and Google DeepMind publicly supported these proposals. The plaintiffs contend that while individual companies may choose to slow down for safety, coordinating this effort among competitors constitutes an unlawful restraint of trade.
