Case type Proposed consumer antitrust class action[1]
Claims / issues Sherman Act § 1; Clayton Act damages and injunctive relief[1]
Status September 18, 2026: complaint filed[1]

Four consumers filed a proposed class action against Anthropic, 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.[1]

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.[1]

Politico reported the filing and said the defendants had not immediately responded to its requests for comment.[2]
