Anthropic’s power-user tier for its Claude AI assistant is under legal fire, as a proposed class-action lawsuit accuses the company of selling “Max” subscriptions that deliver far less usage than the bold 5x and 20x multipliers touted in its marketing.
Filed in mid-June 2026 in the U.S. District Court for the Northern District of California, the complaint names Claude subscriber Karl Kahn as the lead plaintiff and seeks class status on behalf of U.S. customers who bought the Max 5x or Max 20x plans since their launch in April 2025. The suit claims Anthropic’s actual limits are closer to three-and-a-half times Pro on the Max 5x tier and only six to eight times Pro on Max 20x, far below the advertised fivefold and twentyfold boosts. The filing alleges false advertising and unfair business practices, and pegs the amount in controversy at more than $5 million, excluding attorneys’ fees and costs.
At the center of the dispute are Anthropic’s Max subscriptions: Max 5x, priced at $100 per month, and Max 20x, at $200 per month, positioned as premium options for developers, researchers, and other heavy Claude users. Anthropic’s own help center materials describe Max 5x as providing five times more usage per session than the $20 Pro plan, and Max 20x as offering twenty times more usage per session, with allocations resetting every five hours. Those same docs note that Max plans also carry a weekly usage limit across all Claude models, which resets at a fixed day and time tied to each account. The lawsuit argues that these weekly caps and other internal throttles effectively erase the headline multipliers for customers who use Claude heavily, turning what looks like unlimited “turbo” access into a much narrower runway.
For the geek and dev crowds who adopted Claude as a coding buddy and creative partner, the friction around limits is not new. In 2025, Anthropic announced detailed rate limits for Claude Code, spelling out expected ranges of Sonnet and Opus model hours for Pro and Max subscribers and emphasizing that usage is governed by rolling five-hour windows. The company subsequently said it was doubling Claude Code’s five-hour rate limits across Pro, Max, Team, and enterprise plans, signaling that heavy usage was both a core feature and a stress point for its infrastructure. Third-party trackers and comparison sites have tried to translate Anthropic’s messaging into concrete numbers—often estimating hundreds of messages per window and large hour blocks per week for Max tiers—but nearly all of them flag that actual usage can vary and that internal caps and safety systems can quietly cut sessions short.
The complaint now puts those nuances under a microscope, arguing that while Anthropic may technically offer larger per-session allocations, undisclosed or under-emphasized weekly ceilings mean many Max subscribers never see anything close to the advertised 5x or 20x experience. Engadget’s reporting notes that the suit focuses specifically on how Anthropic framed Max as a simple multiple of Pro usage, without clearly spelling out the complex network of time windows and weekly caps that govern real-world access. For creators running long-lived story prompts, coders grinding through refactors in Claude Code, or teams leaning on Claude for documentation and test generation, hitting an invisible wall mid-project can feel less like “fair use controls” and more like bait-and-switch.
Beyond Anthropic, the case lands in a moment when subscription-based AI services are racing to lock in power users with tiered plans that promise more context, more tokens, and more time—often described in shorthand multipliers that hide the fine print. Consumer advocates have already drawn parallels between this lawsuit and past actions against ISPs, streaming platforms, and mobile carriers that advertised big numbers while quietly enforcing caps. The plaintiffs are asking for refunds, damages, and injunctive relief that could force Anthropic to rework how it markets Max and to surface clearer, more prominent disclosures around usage limits. The case is still in its early stages, but for anyone building workflows atop Claude, the outcome could help define how transparent AI companies must be when they sell “more” to their most dedicated users.
