Anthropic faces lawsuits over Claude Max plans
Anthropic has had a class action lawsuit filed against the company by a Washington, D.C.-based customer, with claims that the AI provider’s Claude Max subscription tiers delivered far less usage than was advertised, and offered less value for money than expected.
The lawsuit, filed on behalf of Claude user and subscriber Karl Kahn, is based on alleged fraud in Anthropic’s Claude Max 5x and Max 20x plans, priced at $100 and $200 per month. Both tiers promised multiples of the base Claude Pro plan’s usage, however, Kahn claims the actual limits were not as distinct and shifted without adequate notice, according to reporting by the WSJ.
The lawsuit seeks class-action certification covering subscribers who have used the Max plans since April of last year.
Difference in promised features and delivered product
The lawsuit filed by the Claude user focuses directly on the gap between the language used in marketing of these Anthropic products, and the actual service received.
Anthropic has widely marketed the Max 5x and 20x tiers of its standard Claude Code Pro subscription as direct scaling options and multipliers of base usage limits for the product. However, a lot of heavy users, particularly developers who rely on Claude for coding and technical solutions, are said to have raised complaints about the actual amount of usage they received from the premium service.
The suit alleges the advertised limits were not adhered to, and that Anthropic altered them without giving subscribers any clear notice.
Usage caps have become a major topic of conversation across users and providers of subscription-based AI services. Unlike traditional software subscriptions, where the marginal cost of serving additional users is relatively low, every interaction with an artificial intelligence model requires the use of computing resources that carry real operational costs. Each prompt and response consumes processing power, driving expenses tied to data centers, chips, and energy usage.
That economic reality has pushed AI providers toward implementing stricter usage controls, including throttling mechanisms, rate limits, and daily message caps designed to manage infrastructure demand and maintain profitability.
Google now publishes fixed daily prompt limits for its Gemini service, while Anthropic has taken steps to block third-party tools that allowed subscribers to run high-volume workloads through consumer-tier plans at flat subscription rates.
Anthropic and its power-user cost problem
According to PYMNTS, heavy users on Anthropic’s $200/month Claude Code plan can consume between $600 and $1,500 worth of compute for a flat fee. Lower prices attract more subscribers, but the premium tier customers tend to be the most expensive to serve due to their heavy usage.
That dynamic makes AI subscriptions structurally different from other plans like Netflix or Spotify, where one more viewer or listener adds almost nothing to the bill. For AI companies, each heavy user is a direct cost center for the service.
The pricing pressure is also intensifying from the other AI companies and competitors, with Google dropping its entry-level AI Plus plan from $7.99 to $4.99 per month and cutting its top-tier offering from $250 to $200. OpenAI is also reportedly weighing its own reductions, while Meta has started testing paid AI subscriptions for the first time.
