The Facts

  • A U.S. federal judge has ruled that the AI firm Anthropic must face claims that it misled buyers by advertising Claude Max as offering "5x or 20x more usage" than Claude Pro, letting deceptive advertising, negligent misrepresentation and contract claims proceed.
  • The lawsuit, initially filed in June by Karl Kahn, alleged that Anthropic's $100-per-month Max 5x subscription provided only 3.5 times the usage of its Pro plan, while the $200 Max 20x plan offered between six and eight times Pro's usage.
  • Although Anthropic's website stated that the multipliers were applied on a per-session basis, Kahn, later joined by Solomon Smith, argued that this qualification was not sufficiently prominent or clearly communicated to consumers, and that the term "session" itself was inadequately explained.

The Spin


Prosecution narrative

Thanks to poor advertising and unclear guidance, Anthropic misled users into buying Claude Max plans, thinking the purchase would increase their number of sessions, while burying the math behind the multipliers out of sight. This is an unacceptable breach of consumer trust. After all, advertising should match what it claims.

Defense narrative

Anthropic clearly outlined in its fine print exactly what it meant when it advertised Claude Max's multiplier, spelling out that this applied per session and that weekly caps are separate. The company should not be penalized because consumers misunderstood this qualification, especially since it appears in the sign-up process.
