Anthropic faces class-action lawsuit over Claude subscription limits

The lawsuit, filed Monday in the U.S. District Court for the Northern District of California, targets Anthropic’s Max 5x and Max 20x subscription tiers. Kahn contends that these plans, marketed as offering five and 20 times the usage of standard Pro subscriptions, impose restrictive caps that hinder professional coding and development work. According to the filing, a single five-hour session reportedly consumed 15% of a weekly allowance, forcing users to either halt their projects or purchase additional access.

Evidence cited in the complaint includes internal communications from July 2025, which allegedly reveal a stark discrepancy between the company’s marketing promises and the actual weekly usage allowances provided to subscribers. The plaintiff seeks to represent all customers who purchased these tiers since April 2024, arguing the company’s practices constitute misleading or fraudulent conduct. This legal challenge arrives as Anthropic navigates broader scrutiny, including the recent suspension of its Fable 5 and Mythos 5 models due to U.S. export control directives.
