Consumers sue Anthropic, OpenAI, SpaceXAI, and Google alleging antitrust pact to slow AI development
Subscribers to paid artificial intelligence services sued Anthropic, OpenAI, SpaceXAI, and Google in the Northern District of California on September 18, 2026, alleging the companies formed an illegal horizontal agreement to slow frontier model improvements. The complaint claims public statements endorsing coordinated development pacing, presented as AI safety measures, constitute an unlawful restraint on output and product quality under Section 1 of the Sherman Act, depriving consumers of faster competitive innovations.
Corrected . An earlier version of this piece misquoted the complaint. It attributed to paragraphs 111 and 112 a sentence the complaint does not contain; the complaint's words, in paragraph 112, are now quoted. It quoted Sam Altman as writing "OpenAI will do the same"; the complaint quotes "will do the same." It placed quotation marks around several passages the complaint paraphrases, gave some paragraph numbers incorrectly, and said each plaintiff subscribed to one defendant's product; three plaintiffs allege subscriptions to all four. It also quoted Dario Amodei's essay beyond what the complaint quotes. The piece now links the desk's copy of the complaint as filed.
