The Anthropic lawsuit has raised new questions over premium Claude subscription limits. A proposed class-action complaint says customers paying up to $200 per month received less access than Anthropic’s marketing suggested. The case targets higher-tier Claude users in federal court.
The lawsuit was filed on Monday in the U.S. District Court for the Northern District of California. Washington, D.C. resident Karl Kahn is seeking class-action status. The case relates to customers who purchased premium Claude plans since April 2024.

Anthropic Lawsuit Questions Paid Claude Access Claims
The Anthropic lawsuit targets the plans of the Max 5x and Max 20x. The prices for those subscriptions are $100/month and $200/month. According to the complaint, Anthropic marketed them as providing five times and 20 times the amount of usage compared to Claude Pro.
Kahn says that the offered access was not the same as the restrictions placed on subscribers. The filing alleges that users would be unable to accurately anticipate the arrival of caps. It also states that the allowances were less than expected by customers.
The Anthropic lawsuit alleges that restrictions impacted users with extended work sessions using Claude. Kahn said that he has upgraded to Max 20x because he has been using Claude more for coding. One five-hour session consumed approximately 15% of his weekly allowance, according to the complaint.
Then subscribers had to change their work patterns, the filing states. Several users had to cease their use of Claude until their limits were reset. Others were forced to ration access or purchase additional use to complete projects, the complaint said.
The complaint also cites emails that Anthropic allegedly sent to subscribers in July 2025. Those messages outlined the usage level one could expect in a week by model and tier, the filing says. The disclosures revealed the disparity between marketing and delivered access, Kahn says.
Claude Subscription Business Faces Consumer Scrutiny
The Anthropic lawsuit alleges that the company used misleading or fraudulent marketing. The plaintiff is seeking relief for affected customers. The filing does not show that the court has made any finding on those claims.
The case comes as Anthropic continues to draw investor attention. The company has been in a rumored listing. The complaint places its subscription business under consumer scrutiny during that period.
The Anthropic lawsuit also comes amid a wider crackdown on big AI firms. OpenAI has recently been the subject of a multistate investigation for consumer harm related to ChatGPT. That probe drew attention after reports said OpenAI had confidentially filed paperwork for a potential IPO.
Anthropic has also faced a separate dispute over advanced model access. Following a U.S. government order related to export controls, the company has stopped offering its Fable 5 and Mythos 5 models. Anthropic says that other Claude models were still available.
The company stated that the order necessitated foreign-national restrictions. Anthropic said those restrictions were for foreign-national workers both inside and outside of the U.S. The Anthropic lawsuit now challenges its paid Claude plans under a separate consumer-facing challenge.
