Four AI firms sued for slowdown deal

A lawsuit filed in California federal court claims Anthropic, OpenAI, SpaceXAI and Google illegally agreed to coordinate slower AI development, violating antitrust laws.

The coordination began in September

On September 12, Anthropic CEO Dario Amodei published an essay calling for industrywide cooperation on slowing AI advancement for safety. OpenAI, SpaceXAI and Google leaders publicly agreed the same day.

Earlier signs of coordination

In July 2026, high-ranking employees from multiple AI labs signed a statement acknowledging competitive pressure not to slow development alone, calling on government to support a global slowdown effort.

Plaintiffs want individual accountability

Paid subscribers to ChatGPT, Claude, Grok and Gemini are suing on behalf of a nationwide class. They don't oppose companies slowing individually, but argue antitrust law forbids coordinated agreements.

“AI will quickly spin out of human control and could kill us all if we allow AI safety and protocol to be controlled by private self-serving agreements”

Amodei sought government cover

In his essay, Anthropic's CEO acknowledged antitrust risks and asked the government to mediate or enable cross-lab discussions, suggesting companies need a legal waiver to coordinate on safety.

Trump opposes regulation and exemptions

President Trump rejected calls for AI regulation, calling them a conspiracy. He opposes antitrust exemptions and wants American AI labs to outpace Chinese competition.

Republicans block exemption path

Senator Josh Hawley said he would never approve an antitrust exemption for the world's most powerful companies, warning they could use it to collude and stifle competition.

The legal path forward is blocked

The companies sought government approval for their coordination, but Trump and Republicans oppose both regulation and exemptions. The lawsuit now tests whether their agreement violates existing antitrust law.
