Buist v. Anthropic, PBC

What this case is about

Consumers are suing Anthropic, the company behind the Claude artificial intelligence assistant, alleging that the company engaged in anticompetitive behavior in violation of federal antitrust law. The plaintiffs claim that Anthropic used improper tactics to dominate or suppress competition in the AI services market, harming consumers by limiting their choices or artificially affecting pricing and access to competing AI products. The lawsuit seeks to represent a class of consumers who purchased or used Anthropic's AI services and were allegedly harmed by these anticompetitive practices. The case is in its early stages, and the proposed class likely includes individuals across the United States who paid for or otherwise used Anthropic's products and services during a relevant time period defined in the complaint.
