Anthropic Must Face Lawsuit Over Claude Max Subscription Marketing, US Judge Rules

Anthropic must face key claims in a proposed class-action lawsuit alleging that its Claude Max subscription marketing misled customers about usage limits, according to Reuters.
The plaintiffs argue that advertising promising five or 20 times more usage than lower-priced plans could reasonably be understood as applying to overall monthly usage. Anthropic maintains that the advertised multiples refer to usage within individual five-hour sessions.
US Magistrate Judge Alex Tse allowed claims involving deceptive advertising, negligent misrepresentation and breach of contract to proceed, while dismissing other allegations. The ruling does not establish that Anthropic violated the law.
The dispute concerns the company's $100 and $200 monthly subscription tiers and the relationship between advertised usage allowances and separate weekly limits. The case could influence how AI service providers communicate usage restrictions to paying customers.
