A new class action lawsuit accuses Anthropic of misleading the customers who pay the most for its Claude AI chatbot. The complaint centers on the company’s Max subscription plan, which is marketed as a premium tier above the $20-per-month Pro option. Max offers two price points: $100 per month for what Anthropic advertises as five times the usage limits of Pro, and $200 per month for twenty times those limits. The lawsuit claims those multipliers are deceptive because they are tied to five-hour session windows that are capped by a separate weekly allowance, reducing the actual total capacity increase.
The plaintiffs argue that a consumer cannot reasonably understand the true limits from the marketing materials alone. To grasp the terms, a user must click through multiple hyperlinks to find the word “session” and then visit the Pro plan’s webpage to learn what that term means in practice. The complaint was originally filed in July, then withdrawn and refiled as an expanded class action. One Reddit user compared the situation to receiving a larger fuel tank while the pump only delivers one gallon every five hours, suggesting the weekly allowance creates the illusion of generous access while the rolling window controls real work capacity.
Anthropic has pushed back, filing a motion to dismiss the earlier case. In that motion, the company argued that the session limits were not omitted from its marketing, but were accessible to anyone who clicked the provided links during the purchase process. Anthropic compared this to flipping a product over to read the back label in a physical store. The company’s position is that the clarifying information was technically available before checkout.
The attorneys leading the case, who say they spent a combined 38 years at the Federal Trade Commission, reject that defense. One of them argued that consumers have no way to audit what an AI service actually delivers before paying, so they must rely on the marketer’s claims. She said the situation forces users to take a leap of faith in an honest marketplace, which is not fair when a subscription costs between $100 and $200 per month. She also noted that false advertising law treats marketing as commercial speech, and lying in that context has a long precedent of being illegal.
The timing of the alleged deception matters. Anthropic announced the Max plan in April 2025, but did not impose the disputed weekly limits until August of that year, as the company sought to compete with OpenAI. The lawsuit also arrives amid broader frustration among AI customers who say major labs are passing on steep operating costs. In the latest model release from Anthropic, called Fable 5.1, the company acknowledged feedback on price, writing that it was addressing customer concerns about cost in the new product’s pricing structure.
Beyond the technical terms, the lawyers said they were drawn to the case because of who is affected. They began hearing from users who felt pressured to pay for high-tier AI subscriptions to stay relevant in the job market, yet often believed they were not receiving the value promised. The attorneys stressed that even if Anthropic’s stipulations appear somewhere on its website, the burden should not fall on the consumer to hunt for them. One lawyer described the company’s approach as “buyer beware,” which she said is not fair to people making a significant monthly financial commitment.
