Key points
- The order denies dismissal of Smith's CLRA, negligent misrepresentation and breach of contract claims, and grants it, with leave to amend, for Kahn's CLRA, UCL, FAL and implied-covenant claims.
- The order says Max weekly limits are higher than Pro's but not 5x or 20x higher; the plaintiffs calculate 3.5 times and 6 times Pro's weekly usage on Sonnet 4.
- Plaintiffs have leave to amend, with an amended complaint due on 2 December 2026; if they do not amend, Anthropic must answer by 16 December 2026.
What happened
A federal judge ruled that Anthropic's promise of "5x or 20x more usage" for Claude Max is plausibly misleading, so a proposed class action by Max subscribers will go forward. Magistrate Judge Alex G. Tse made the ruling in an order on a motion to dismiss in Kahn v. Anthropic PBC, No. 26-cv-05763-AGT, in the Northern District of California, filed on 6 November 2026.
The plaintiffs say Anthropic markets the Max 5x and Max 20x plans as giving 5x or 20x more usage than Pro. The order says Max subscribers do get 5x or 20x more usage per five-hour session, but their weekly limits are not 5x or 20x higher. It cites the plaintiffs' calculation that for the Sonnet 4 model Max 5x users get 3.5 times and Max 20x users 6 times Pro's weekly usage.
Anthropic said its help pages disclose that the multiples apply per session. The judge noted that disclosure sits two hyperlinks away from the main sales pages, outside the sales funnel, and said that because payments are due monthly, customers could plausibly read the promise as monthly.
The motion was granted for one plaintiff's consumer-protection claim, the unfair-competition and false-advertising claims, and the implied-covenant claim, all with leave to amend. It was denied for the other plaintiff's consumer-protection claim, negligent misrepresentation and breach of contract. An amended complaint is due on 2 December 2026.
What it means for you
Our viewThis is an early ruling on a motion to dismiss, not a finding of fact. The court wrote that the advertising is plausibly misleading, and the weekly-usage multiples are the plaintiffs' own calculation.
Anthropic says its help pages disclose that the multiples apply per session; the order notes that disclosure sits two hyperlinks away from the main sales pages, and reasons that because payments are due monthly, customers could plausibly read the promise as monthly.
If you buy a plan on a stated usage multiple, check which period the multiple refers to, and watch for the amended complaint due on 2 December 2026.
