What happened
Judge Tse ruled that the 'five or twenty times more usage' marketing for Claude Max 5x ($100/mo) and Max 20x ($200/mo) plausibly misled monthly subscribers, allowing negligent-misrepresentation, breach-of-contract and one California consumer-protection claim to proceed in Kahn v. Anthropic.
Why it matters
The ruling means Anthropic must defend its subscription marketing in court, a potential precedent for how AI plan usage limits are described to paying customers.
WHO IT HITSThis ruling directly affects Anthropic's paying subscribers on the Claude Max 5x and Max 20x tiers, who may now be part of the class, and it puts pressure on how AI companies market usage multipliers to consumers.
Summaries like this, every morning.
The case centers on how Anthropic described the usage limits of its Claude Max tiers. According to the complaint, the 5x and 20x multipliers that appear in the marketing apply per five-hour session rather than per month, resulting in actual delivery of roughly 3.5x and 6–8x Pro. Judge Tse found that this discrepancy plausibly misled monthly subscribers, allowing several claims to advance.
The class period covers anyone who subscribed to either tier since April 9, 2025, meaning a broad set of paying customers could be affected. The ruling does not resolve the case but ensures that Anthropic will have to answer the allegations in court. How the company defends its marketing language may draw attention from other AI providers that sell tiered subscription plans with usage multipliers.
