A class-action lawsuit alleges that a coordinated slowdown by Anthropic, OpenAI, Google, and SpaceX violated antitrust law.[^1]

The suit additionally claims OpenAI operated an internal program named Project Lily. Under this program, third-party contractors read and summarised user prompts, and scored ChatGPT responses on a 1-to-7 scale for model training.[^4]

Lonsdale, an investor associated with Anthropic, criticised moves by figures close to Anthropic and OpenAI to fund third-party groups that lobby for stricter industry rules at the Reuters Momentum AI Austin event.[^2]

As of 31 August 2024, top holdings of the ARK Venture Fund included SpaceX at 7.54%, OpenAI at 5.26%, and Anthropic at 3.86%.[^3]
