What happened
A lawsuit filed on September 18, 2026, alleges that Anthropic PBC, OpenAI OPCO LLC, SpaceXAI, and Google LLC coordinated to slow the pace of AI development. The complaint states that the companies' executives publicly agreed with an essay advocating for limits on AI progress, effectively conspiring to restrain competition.
The plaintiffs, who are consumers subscribing to the defendants' AI services, argue that this coordination violates Section 1 of the Sherman Antitrust Act. They claim that the agreement among competitors about the rate of product improvement is illegal and that they are effectively overcharged for slower-improving products.
The lawsuit seeks class certification, an injunction against the companies, and a declaratory judgment that they violated federal antitrust law. The plaintiffs are represented by Trial Lawyers for Justice.
