Anthropic is facing a class action lawsuit over allegations of misleading claims regarding its Claude Max AI subscription services.
Anthropic Under Legal Fire for Subscription Claims
Anthropic is embroiled in a class action lawsuit alleging that it misrepresented the usage limits of its Claude Max AI subscription services. Filed on June 14 in California, the lawsuit is spearheaded by Karl Kahn, who claims the Max 5x and Max 20x tiers provide significantly less usage than advertised.
Kahn, who upgraded from Claude Pro to the Max plans earlier this year, asserts he overpaid for both subscriptions and had to purchase additional usage after reaching the limits of his plans. The lawsuit seeks damages, restitution, and class action status for all U.S. residents who subscribed to the Max services since April 2025.
Kati Daffan, Kahn's attorney, emphasized that the case hinges on consumer protection laws that require truthful advertising. "This is a strong candidate for a class action because the law clearly states that companies must be truthful in their advertising and marketing,” she stated. Daffan pointed out that the ambiguity in how usage is calculated has left many consumers unable to determine if they are receiving the service promised.
Anthropic's subscription offerings include a free plan and paid options such as the $20 monthly Pro plan and the more expensive Max tiers, which are marketed as providing significantly higher usage limits. The Max 5x plan is priced at $100 per month, while the Max 20x plan costs $200 per month, both claiming to offer enhanced access to the AI's capabilities.
Customers have reportedly raised concerns on various forums about the actual service levels they have received, indicating a widespread feeling of dissatisfaction with the current offerings. The lawsuit argues that this lack of clarity has prevented users from understanding their entitlements under the Max subscriptions.
In addition to seeking financial restitution, the lawsuit calls for injunctive relief, which would require Anthropic to amend its marketing practices. As of now, the company has not publicly responded to the allegations.
This legal action comes shortly after Anthropic's recent AI model launches, which faced criticism due to usage limitations and concerns over national security that led to a U.S. government order to restrict access to certain models for foreign nationals.
