Artificial intelligence company Anthropic faces a proposed class-action lawsuit alleging it misled premium customers of its Claude chatbot. The complaint, filed in federal court, claims subscribers to the $100/month Max 5x and $200/month Max 20x plans received less access than marketing promised. Plaintiff Karl Kahn states users were forced to ration usage or purchase more to finish work, raising questions about the company’s subscription business model.
Anthropic is facing a consumer lawsuit over the limits of its premium Claude subscription plans. A proposed class-action complaint filed in California federal court alleges customers received less access than marketed.
The lawsuit specifically targets the Max 5x and Max 20x plans priced at $100 and $200 per month. Plaintiff Karl Kahn claims marketed usage multiples did not match the restrictions subscribers actually encountered.
The filing alleges users could not accurately predict when caps would be reached during work. Subscribers were allegedly forced to stop using Claude or ration their access as a result.
The complaint cites emails from July 2025 that allegedly disclosed the disparity. Kahn said a five-hour coding session consumed about 15% of his weekly allowance under the Max 20x plan.
The lawsuit alleges Anthropic engaged in misleading or fraudulent marketing of its plans. The case places the company’s subscription business under scrutiny amid investor attention.
This action follows a wider regulatory focus on major AI firms. OpenAI has been the subject of a multistate investigation for potential consumer harm, as reported, following its own confidential IPO filing reports.
Anthropic has also recently restricted access to certain advanced models due to a U.S. government order. The company stated the move was necessitated by export control-related foreign-national restrictions.
