Anthropic is facing a federal class-action lawsuit for allegedly misleading customers about usage limits in its premium subscription tiers, according to a report.
The complaint, filed on behalf of Washington, D.C.-based user Karl Kahn, alleges that “oversold the usage allowances” tied to its high-end “Max 5x” and “Max 20x” Claude AI plans, Wall Street Journal reported..
The lawsuit claims the company’s marketing of higher-tier subscriptions is “misleading,” arguing that “the actual usage provided by the Max 5x and Max 20x plans is far below the advertised amount of usage,” as per WSJ.
Claims of confusing or restricted usage caps

The suit alleges promoted the plans as offering five times and 20 times the usage of its standard Pro subscription, but users reportedly encountered stricter real-world caps than advertised.
Complainant says work was disrupted
The lead plaintiff, Karl Kahn, reportedly upgraded to the $100-per-month Max 20x plan but quickly ran into limits.
He “found himself needing either to halt his work, ration his usage, or purchase additional usage to ensure that he could complete his work,” the lawsuit states, according to the report.
