AI companies sued for "collusion" to slow down
A class-action lawsuit alleges that Anthropic, OpenAI, SpaceXAI, and Google illegally coordinated to slow the pace of AI development, violating federal antitrust laws. The plaintiffs argue that executives from these competing firms agreed to limit progress, effectively creating a cartel that restrains competition and harms consumers. The suit seeks an injunction and a declaration that the companies violated the Sherman Antitrust Act by agreeing on the rate of product improvement.
- ▪The lawsuit names Anthropic, OpenAI, SpaceXAI, and Google as defendants for allegedly conspiring to restrict the speed of AI advancements.
- ▪Plaintiffs claim the coordination began when Anthropic CEO Dario Amodei published an essay advocating for industry-wide limits on AI progress, which was subsequently endorsed by leaders from the other companies.
- ▪The complaint asserts that this agreement violates Section 1 of the Sherman Antitrust Act by functioning as an output-restricting cartel among competitors.
- ▪Consumers are seeking class certification, an injunction against the defendants, and a declaratory judgment that federal antitrust laws were breached.
- ▪The case, titled Buist v. Anthropic PBC, was filed in the Northern District of California, with the plaintiffs represented by Trial Lawyers for Justice.
