Judge Lets Anthropic Face Class Action Alleging Claude Max 5x and 20x Plans Deliver Far Less Usage Than Advertised

Judge Tse ruled the 'five or twenty times more usage' marketing on Claude Max 5x ($100/mo) and Max 20x ($200/mo) plausibly misled monthly subscribers, letting negligent-misrepresentation, breach-of-contract and one California consumer-protection claim proceed in Kahn v. Anthropic. The complaint says actual delivery is roughly 3.5x and 6–8x Pro, because the 5x/20x multipliers apply per five-hour session, not per month. The class period covers anyone who subscribed to either tier since April 9, 2025.
