Anthropic's '20x' Max Claim Draws Expanded Class Action

An expanded class action alleges Anthropic's $200-a-month Max plan never delivered the "20x" usage its marketing graphics advertise. The Verge reported the filing on 8 September 2026.

The complaint matters beyond Claude because it puts a familiar developer grievance — buying a top tier and hitting a wall anyway — in front of a court rather than a support queue.

What the complaint alleges

Per The Verge's report, Max is "an upgrade to the $20/month Pro plan" with "two pricing options: $100 per month for '5x' the usage limits of Pro or $200 per month for '20x'." The subscribers' claim is not that those multiples are invented, but that they are qualified where nobody reads.

The report states the allegation directly: the numbers are "misleadingly couched in fine print", because the promised 5x or 20x is "only promised for five-hour chunks of time that are subject to a weekly limit — which the complaint alleges adds up to a much smaller total increase in usage capacity."

How buried, per the report: it "requires clicking two different hyperlinks to see the word 'session,'" and understanding that word means going to the Pro plan page for an expanded definition. One Reddit user quoted in the piece put the mechanism plainly: "It's like giving someone a bigger gas tank while keeping the fuel pump limited to one gallon every five hours."

The suit was brought by Vaca and Kati Daffan, who "both formerly worked at the Federal Trade Commission under Lina Khan" — by Vaca's account, 38 years at the agency between them. Her legal framing: "There is a long line of precedent on false advertising. It's commercial speech. You can't lie when you're marketing a product."

Anthropic's position

An earlier version of the complaint was filed in July, then withdrawn and refiled as this expanded class action. In its motion to dismiss that first case, Anthropic argued the terms were never hidden: accessing the clarifying information "required nothing more than clicking hyperlinks available in the purchase process—the digital equivalent of flipping a product over to read the back label."

The Verge reports Anthropic "did not respond to a request for comment" on the new filing. Nothing has been decided; these are allegations and a contested motion.

The timeline is the interesting part

Anthropic announced Max in April 2025, but per the report it "didn't impose the allegedly deceptive weekly limits until a few months later in August, as the company pushed to compete with OpenAI." The advertised multiples and the constraint that allegedly undercuts them arrived months apart.

The same report notes Anthropic said of its latest model release, Fable 5.1, that it was "addressing the feedback we've received from customers on price." It also notes Anthropic treats power users as central to its business, "even when it means cutting off other popular applications, like OpenClaw."

If you pay for a top tier

The practical lesson is independent of how the case lands. A usage multiple stated against another plan tells you nothing until you know the window it is measured over. Check whether your limit is a monthly pool, a weekly ceiling, a rolling session, or all three at once — and measure your own throughput before upgrading mid-project, which is exactly the moment Vaca says people buy.

Worth watching: whether the ex-FTC framing survives the motion stage. A ruling that "available if you click through" is not adequate disclosure would land on every metered AI plan, not just this one.
