Lawsuit alleges misleading advertising for Anthropic's Claude Max subscription
A group of Claude users has filed a lawsuit against AI company Anthropic, alleging misleading advertising regarding usage limits and terms for its highest-tier Max subscription plan.
AI company Anthropic, the developer of the Claude chatbot, is facing a class-action lawsuit from users who claim the company engaged in misleading advertising for its top-tier Max subscription plan. The core of the dispute centers on the clarity of usage limitations associated with the service.
The lawsuit contends that Anthropic failed to adequately disclose the specific restrictions tied to its Claude Max offering, which was launched in April 2025. The service was advertised as providing 5x or 20x "usage credits" compared to the Pro tier for a monthly fee of $100 or $200, respectively. For context, Claude Pro costs a minimum of $17 per month when billed annually.
The central argument in the lawsuit revolves around the interpretation of these "usage credit multipliers." Plaintiffs allege that the advertised 5x or 20x multipliers apply only to session-based usage that resets every five hours, and not to weekly usage caps. Furthermore, Max subscribers are subject to a weekly usage limit, a restriction that was reportedly added months after the plan's initial release, in August 2025.
While Anthropic updated its Claude support pages on August 7, 2026, to detail the Max plan's restrictions, one of the plaintiffs' attorneys stated that these terms are not sufficiently clear. Consumers, according to the attorney, must navigate multiple links to understand the true meaning of the multipliers. This lack of transparency has prompted the legal action.
The case highlights growing concerns about transparency in the pricing and terms of service for advanced AI subscription models.
