A Washington DC subscriber is suing Anthropic for allegedly delivering six to eight times Pro usage on a plan marketed as twenty times, and the timing could not be worse with a near-trillion-dollar IPO on the horizon.
Karl Kahn started with Claude Pro in June 2025, upgraded to Max 5x in January, then Max 20x in April. He paid $200 a month for what Anthropic advertised as twenty times the usage of its Pro tier. One five-hour session burned through 15 percent of his weekly allowance. According to a complaint filed June 14 in the U.S. District Court for the Northern District of California, the Max 20x plan actually delivers six to eight times Pro usage in practice, and Max 5x delivers closer to three and a half times rather than five. Kahn is now suing for the rest of the subscriber base too.
The complaint brings claims under California's Consumers Legal Remedies Act and False Advertising Law, plus negligent misrepresentation and breach of contract. It seeks class certification for every U.S. resident who bought Max 5x or Max 20x through Claude.com or the Claude desktop app since April 9, 2025, and asks for damages, restitution, and injunctive relief. Anthropic declined to comment.
Part of what makes this lawsuit credible is not just the gap between advertised and actual usage, it's that Anthropic gives subscribers no way to track the gap in real time. There's no dashboard showing how much of a 5x or 20x allowance you've consumed. Usage resets on rolling five-hour windows and then again on a weekly basis, two separate throttles stacked on top of each other, neither of them spelled out clearly before you upgrade. As Engadget noted, you find out you've hit a cap by hitting it. That's not a minor UX oversight. When someone is paying $200 a month for a multiplier, they need to know what they're multiplying and where they stand.
OpenAI doesn't exactly cover itself in glory on this front either. ChatGPT Plus in 2026 runs dynamic caps that shift with traffic levels and system load. OpenAI publishes a message count for GPT-5.5, currently 160 messages per three hours on the Plus plan, but the fine print acknowledges that
