Anthropic Faces Class-Action Lawsuit Over Alleged Misleading Usage Limits on Claude Max Subscription Plans

Jun 15, 2026

Anthropic faces a class-action lawsuit alleging it misleads customers about its premium Claude Max subscription plans. The suit, filed by Karl Kahn, claims the $200/month "Max 20x" plan delivers only 6-8 times the usage of the base plan, not the advertised 20x. The complaint highlights opaque usage calculation methods and a history of user complaints, testing how AI companies market services with complex, token-based costs.
