A federal court filing seeks to block an agreement between Anthropic, OpenAI, SpaceXAI, and Google to coordinate the pace of research and development. The lawsuit alleges 4 companies created an output restricting cartel that keeps retail prices stable while deliberately slowing the progress of competing AI tools to the detriment of paying users.

Elon Musk joined the legal action, claiming that safety standards written and policed by the industry itself are insufficient. The case argues that AI labs cannot coordinate R&D schedules, even when the calls for pacing are made publicly, without risking antitrust violations for restricting market competition.
