Four consumers filed a proposed class action against [[Anthropic]], [[OpenAI|OpenAI OpCo LLC]], SpaceXAI LLC and Google LLC on September 18, 2026. They allege that coordination to slow improvement of competing AI subscription products violates Section 1 of the Sherman Act.<ref name="buist-complaint">[https://drive.google.com/file/d/1ufb8Bg9RA9LmRKOvXSm9UbP9YITI9sDq/view Buist et al. v. Anthropic PBC et al., No. 3:26-cv-10693 (N.D. Cal.), ECF 1, filed September 18, 2026, pp. 1–7, 25–29.]</ref>

== Claims and requested relief ==
The complaint seeks class certification, treble damages and injunctive relief. It frames the alleged injury as reduced product quality and slower improvements for subscription prices paid. The pleaded challenge concerns an alleged agreement among competitors; the requested relief preserves independent safety decisions and lawful standard-setting.<ref name="buist-complaint" />

Politico reported the filing and said the defendants had not immediately responded to its requests for comment.<ref name="buist-politico">[https://www.yahoo.com/news/politics/articles/anthropic-openai-spacexai-google-sued-010440086.html Tyler Katzenberger and Christine Mui, Politico via Yahoo News, “Anthropic, OpenAI, SpaceXAI, Google sued over call to ‘pace’ AI development,” September 18, 2026 (September 19 UTC).]</ref>
