Anthropic faces expanded class action over Claude Max usage claims

Anthropic faces an expanded proposed class action filed by Karl Kahn in the Northern District of California over claims that its $100-a-month Claude Max 5x and $200-a-month Max 20x plans mislead subscribers about usable capacity, according to a first amended complaint docketed July 20, 2026. The complaint alleges the advertised five-times and 20-times Pro usage multipliers apply only to rolling five-hour sessions, while separate weekly limits constrain total usage, and raises California consumer-protection and false-advertising claims plus negligent misrepresentation and breach of contract theories. No class has been certified and no court has ruled on the allegations; Anthropic did not respond to The Verge's request for comment, and an earlier motion to dismiss argued the information was available through hyperlinks in the purchase process.

The case targets the $100-a-month Max 5x and $200-a-month Max 20x tiers, which Anthropic advertises as providing five or 20 times the usage of its $20 Pro plan. \ 1\ https://www.theverge.com/ai-artificial-intelligence/990313/anthropic-class-action-lawsuit-pricing-subscription-plans The complaint alleges that the multipliers apply only to rolling five-hour sessions, while separate weekly limits constrain total usage.

The court docket lists a first amended complaint filed July 20, 2026, and identifies claims under California consumer-protection and false-advertising laws, along with negligent misrepresentation and breach of contract theories. <sup \ 3\ https://dockets.justia.com/docket/california/candce/3%3A2026cv05763/472161 </sup The proposed class covers customers who purchased the Max tiers, according to reporting on the complaint. \ 4\ https://theplanettools.ai/blog/anthropic-claude-max-usage-limits-lawsuit-2026 Anthropic’s current help center says Max 5x and Max 20x provide five or 20 times more usage “per session,” with the session resetting every five hours. It also says weekly limits apply across models and that Anthropic may impose additional caps at its discretion. <sup \ 2\ https://support.claude.com/en/articles/11049741-what-is-the-max-plan </sup The company did not respond to The Verge’s request for comment; an earlier motion to dismiss argued that the relevant information was available through hyperlinks in the purchase process. \ 5\ https://www.theverge.com/ai-artificial-intelligence/990313/anthropic-class-action-lawsuit-pricing-subscription-plans The dispute fits a broader line of subscription cases involving allegedly unclear disclosures. In a separate 2026 case, the Federal Trade Commission accused online advice service JustAnswer of enrolling consumers in recurring subscriptions without affirmative consent. Kahn’s case concerns advertised service capacity rather than automatic enrollment, and its allegations remain untested. \ 6\ https://www.ftc.gov/legal-library/browse/cases-proceedings/justanswer Companies mentioned Further sources The stories that matter, in one email.
