Background
Anthropic offers Claude subscriptions at several price points, including a Pro plan priced at roughly $17–$20 per month and two higher "Max" tiers marketed as offering five times and twenty times the Pro plan's usage caps: Max 5x at $100 per month and Max 20x at $200 per month (Source: https://www.wsj.com/tech/ai/anthropic-sued-over-limits-on-its-200-a-month-ai-plans-e2a109e4).
Claims
According to the Wall Street Journal's account of the complaint, the suit alleges that the real usage limits on the Max 5x and Max 20x plans are lower than the advertised multiples and are difficult for subscribers to determine in advance. The complaint rests in substantial part on emails Anthropic sent to subscribers in July 2025 describing the weekly usage each plan was expected to allow (Source: https://www.wsj.com/tech/ai/anthropic-sued-over-limits-on-its-200-a-month-ai-plans-e2a109e4). The suit seeks class-action status covering subscribers since April 2025.
Current status
The complaint was docketed on 14 June 2026 and is in its initial stage; no responsive pleading or class-certification ruling had been reported as of 16 June 2026.
