A proposed class action, Kahn v. Anthropic PBC, was filed June 14, 2026 in the U.S. District Court for the Northern District of California (CourtListener docket 73482575), alleging Anthropic oversold the usage on its premium Claude Max plans. Plaintiff Karl Kahn, a Washington DC resident, claims the Max 5x and Max 20x tiers deliver far less than the advertised 5x and 20x of the Pro plan — and that Anthropic never disclosed how usage is actually measured, so subscribers can’t tell what they’re getting. The suit was first reported by The Wall Street Journal; Anthropic declined to comment.

Key Takeaways

  • The core allegation (quoting the complaint). Max 20x (100/mo, marketed as 5x Pro) allegedly delivers “just three-and-a-half times the usage of Pro” (¶7). The complaint also alleges the “50% savings” pitch on Max 20x is false (¶8). (Pro is 200/yr — ~$17/mo billed annually.)
  • Opacity is central. The complaint calls Anthropic’s website “a black box, without any meaningful description of how usage is calculated,” says “session” is never defined, and argues consumers had no way to verify what they received — which counsel Kati Daffan (Vaca Daffan LLP) says is why no similar suit was filed earlier.
  • Evidence cited. Anthropic allegedly emailed Max subscribers in July 2025 spelling out per-model weekly usage per tier, which the suit says fell below the advertised amount. Kahn’s example: after upgrading to Max 20x for Claude Code work, a single five-hour session burned ~15% of his weekly allowance.
  • The claims. Four causes of action — California Consumers Legal Remedies Act (§1750), False Advertising Law (§17500), Negligent Misrepresentation, and Breach of Contract. Amount in controversy exceeds $5 million.
  • The class. All U.S. residents who purchased or upgraded to Max 5x or Max 20x via Claude.com or the Claude desktop app between April 9, 2025 and the present. Relief sought: damages, restitution, injunctive and declaratory relief, attorneys’ fees, and class certification.
  • Context. The filing landed days after the Fable 5 / Mythos 5 launch, which itself drew complaints that the new models consume subscription allowances faster than earlier Claude models — sharpening the long-running tension between flat subscription pricing and per-token inference cost. ^[inferred]
  • Status. Allegations are unproven; no ruling has been made, and Anthropic has not responded to the substance publicly.
