U.S. Judge: Anthropic Claude Max Misleading Claims Lawsuit Advances

• A federal judge allowed a class action lawsuit against Anthropic to proceed over allegedly misleading claims about its Claude Max AI chatbot subscription.
• U.S. Magistrate Judge Alex Tse found that Anthropic's promise of "5x or 20x more usage" was "plausibly misleading" because customers pay monthly but actual usage limits are per-session.
• Anthropic's defense, pointing to a help page explaining per-session limits, was rejected as the disclosure was not readily accessible from the main sales pages.
• While some claims were dismissed, the lawsuit can continue on allegations of negligent misrepresentation, breach of contract, and a specific claim under California's Consumers Legal Remedies Act.

The judge emphasized that customers paying a monthly fee could reasonably expect the promised 'more usage' to apply to their entire monthly subscription period, not just individual sessions.

A federal judge in California has determined that Anthropic's marketing claims for its Claude Max AI chatbot subscription plans could plausibly mislead consumers, allowing a proposed class action lawsuit to advance. U.S. Magistrate Judge Alex Tse found that the company's promise of "5x or 20x more usage" for its premium Claude Max tiers, compared to the standard Pro plan, was ambiguous and potentially deceptive. This ruling permits key aspects of the lawsuit, brought by customers Karl Kahn and Solomon Smith, to move forward.

The core of the dispute centers on how Anthropic's usage claims are interpreted. While customers pay for their Claude Max subscriptions on a monthly basis, the actual increased usage is applied per five-hour session, not across the entire month. This discrepancy means that Max 20x users, for example, receive only about six times the weekly usage of the Pro plan, rather than the twenty times implied by the advertising. Similarly, Max 5x users experience approximately 3.5 times the weekly usage, falling short of the advertised fivefold increase.

Customers reported significant frustration, with one user on the 20x Max plan noting they had exhausted 50% of their weekly allowance by the third day. Judge Tse concluded that, given the monthly payment structure, it was reasonable for subscribers to understand the

Anthropic defended its advertising by asserting that the

The ruling by Judge Tse split the plaintiffs' claims under California's Consumers Legal Remedies Act (CLRA), a statute designed to protect consumers from deceptive business practices in transactions for personal, family, or household use. Solomon Smith's CLRA claim was allowed to proceed because he demonstrated using Claude for educational purposes, including coursework, coding projects, and an IBM-sponsored hackathon, which the court deemed non-commercial. Tse agreed that educational use does not amount to commercial use. Conversely, Karl Kahn's CLRA claim was dismissed because he only vaguely stated using Claude Code for

This judicial decision carries significant implications for companies offering AI chatbot subscription services, particularly regarding the clarity and accessibility of their marketing disclosures. The ruling underscores that courts may not accept 'fine print' disclosures if they are not readily accessible, increasing exposure to consumer protection claims like those under California's CLRA and potential class actions for negligent misrepresentation or breach of contract. Companies must ensure that claims about usage limits and tiered pricing are transparent and align with customer expectations, especially when services are billed monthly.

The judge's emphasis on the monthly payment structure influencing reasonable consumer expectations highlights a critical area for legal scrutiny in subscription-based models. This case serves as a reminder that the perceived value and limitations of a service must be clearly communicated to avoid allegations of misleading advertising and potential legal challenges.

Lawyers advising AI or tech companies offering subscription services must scrutinize marketing claims, especially regarding usage limits and tiered pricing, to ensure they are not plausibly misleading. This ruling underscores that courts may not accept 'fine print' disclosures if they are not readily accessible, increasing exposure to consumer protection claims like those under California's CLRA and potential class actions for negligent misrepresentation or breach of contract.
