A federal judge has ruled that Anthropic must face claims that its Claude Max plans promised paying subscribers far more usage than they actually deliver. In an order issued on November 6, Magistrate Judge Alex G. Tse found the pitch of '5x or 20x more usage than Pro' plausibly misleading, and allowed a proposed class action by two subscribers to move forward. No class has been certified, and nothing has been proven yet, since the court treats the complaint's allegations as true at this stage.
The session cap versus the weekly cap
Claude Pro costs $17 to $20 a month, while Max 5x costs $100 and Max 20x costs $200. Anthropic renamed the two Max plans Max and Ultra on October 30, but the case concerns the marketing used while they carried the Max names. The dispute turns on what 'more usage' means when a subscriber pays by the month.
Paid Claude plans carry two separate limits: a cap on each five-hour session and a weekly cap. According to the complaint, Max subscribers receive 5 or 20 times Pro's allowance inside a single session, yet their weekly limits are nowhere near 5 or 20 times higher.
For Claude's Sonnet 4 model, the plaintiffs calculate that Max 5x delivers about 3.5 times Pro's weekly usage, while Max 20x delivers about 6 times. The complaint also says one subscriber found that using Max 20x to the full in a single five-hour window could burn 15% of his weekly allotment.
What the judge said
Anthropic argued that customers should understand 'more usage' to mean more per session, citing its help pages. Judge Tse was not persuaded. Because subscribers pay monthly, he wrote, consumers could take the promise to mean 5x or 20x more usage per month. He likened the help page to the back label on a shampoo bottle, which shoppers need not read.
The ruling was mixed. Going ahead are one subscriber's claim under California's Consumers Legal Remedies Act, plus claims of negligent misrepresentation and breach of contract. Dismissed, with leave to amend, were the other subscriber's consumer-protection claim, claims under California's unfair competition and false advertising laws, and a claim that Anthropic broke its duty of good faith by changing limits mid-billing-period.
What happens next
If the plaintiffs do not file an amended complaint by December 2, Anthropic must answer the current one by December 16. Anthropic has not commented. The order does not say whether any certified class would reach subscribers outside the United States. Ultra has dropped its five-hour limit, but every plan keeps the weekly cap at the heart of the case.
Our Read
This is a narrow ruling, not a verdict, and it should be read that way. A motion to dismiss asks only whether the complaint states a claim a court can hear, so the judge treated the subscribers' numbers as true without deciding they are right.
What matters is the reasoning: a monthly price invites a monthly reading, and a disclosure buried two clicks from the sales page may not save the headline promise. If that reasoning survives, every AI company that sells usage in multiples will have to say plainly whether the multiple is per session, per week, or per month.
OpenAI and Google sell premium tiers on usage too, and both have faced complaints when subscribers hit caps early. Anthropic's case is the first to reach a federal judge's reasoning on the point, which is why it carries weight beyond Claude. The industry's habit of advertising a single multiplier, while real limits hide in help pages, is now on trial.
Why It Matters
Usage is what Claude subscribers pay for, so a misleading multiplier strikes at the purchase itself. If the claims proceed, Anthropic may have to rewrite how it sells Max and Ultra, and rivals may follow rather than risk the same challenge. Subscribers should read the weekly cap, not just the headline number, before paying $100 or $200 a month.
Background
Anthropic launched the Max plans in April 2025 for heavy users, and renamed them Max and Ultra on October 30. The two subscribers filed their case in June 2026. Anthropic is heading toward a public listing, with its roadshow expected in the week of November 9.
