Just-In: Elon Musk-Backed Anthropic Faces Lawsuit Over Claude AI Amid SpaceX Hype

Anthropic, the artificial intelligence firm affiliated with Elon Musk’s SpaceX, is now facing a class-action lawsuit. The suit centers around the pricing model for its premium “Claude” AI subscription, which allegedly misleads users on the usage limits.

Anthropic Slapped With Lawsuit Over Claude AI Subscription

The lawsuit was filed Monday in the U.S. District Court for the Northern District of California on behalf of Karl Kahn from Washington, D.C. it seeks class-action status for people who have paid for Anthropic’s higher-tiered plans for the Claude model since April 2024. Despite partner SpaceX IPO hype and even Anthropic’s own IPO plans, the move hints at waning consumer trust.

The crux of the issue is the subscription tiers, with Anthropic’s Max 5x subscription plan at $100/month and Max 20x at $200/month. These plans are marketed as ones that offer five times and 20 times the amount of usage in the company’s standard Pro plan.

However, according to the lawsuit, subscribers are not getting the access they are expecting based on those offers. The complaint states that “the actual usage provided by the Max 5x and Max 20x plans is far below the advertised amount of usage.” The filing also says that the restrictions are difficult for customers to understand or predict.

Nonetheless, Anthropic is not alone in facing legal action in the AI industry. Recently, Sam Altman’s OpenAI was also hit by a multistate probe over alleged user harm due to the use of its ChatGPT chatbot. The move grabbed market attention as it came on the heels of OpenAI’s confidential IPO filing.

Plaintiff Details His Experience With Claude AI

Kahn noted that he switched to the Max 20x plan when he started using the software more for coding and development than for casual use in April. According to the complaint, “a single five-hour work session consumed 15% of his weekly allotment.” He added that this puts him at a disadvantage to continue working.

Consequently, Kahn allegedly “found himself needing either to halt his work, ration his usage, or purchase additional usage to ensure that he could complete his work,” the filing states.

The lawsuit also references emails Anthropic allegedly sent to subscribers in July 2025. These mails outlined the expected weekly usage of various Claude models and tiers for each subscription. Those disclosures emphasize plaintiffs’ argument that the limits to access are not in line with the promoting of these services.

Moreover, the complaint asks that Anthropic’s marketing be deemed fraudulent and/or misleading. It seeks relief for affected subscribers. It has put the much-awaited Anthropic IPO under scrutiny.

Anthropic declined to comment on the lawsuit, The Wall Street Journal reported.
