Anthropic, OpenAI, SpaceXAI, and Google face a federal lawsuit alleging the firms violated antitrust laws by coordinating to pace AI development. The plaintiffs seek a court order to block the alleged agreement, which they describe as an "output-restricting cartel" designed to slow the improvement of competing AI products.

The legal action claims paying users continue to pay the same prices while the companies deliberately restrict the speed of technical progress. The suit targets a coordinated effort to slow the release of new capabilities among the four firms to maintain current market conditions.
