A notable share of ChatGPT users have been moving to rival assistants in March 2026, with Anthropic’s Claude the main beneficiary, according to a Forbes report by Rachel Wells and data from several analytics firms. The shift coincides with an online campaign known as QuitGPT, in which users have urged one another to cancel ChatGPT subscriptions over objections to OpenAI’s business decisions.
The most striking numbers come from Larridin, a workplace AI analytics company whose data Forbes cited. According to Larridin, Claude usage inside the organizations it tracks rose by 1,487 percent over a period of weeks, and Claude users averaged about 38 sessions a week, roughly double the figure for ChatGPT. The company also reported that Claude was being used about twice as much as ChatGPT in the corporate environments it measures.
What is behind the shift
The data reflect a specific sample of enterprise customers rather than the whole market, where ChatGPT still has a far larger user base. Even so, the direction is consistent with other indicators from the same period, including Claude’s rise to the top of app store download charts and reports of a jump in Anthropic’s consumer sign-ups.
Two forces appear to be at work. The first is reputational: the QuitGPT campaign grew out of criticism of OpenAI’s policy choices and partnerships, and some users framed switching as a matter of principle. The second is practical: many users and companies say Claude performs better for particular tasks, especially coding, long-document analysis and writing, which has reinforced the movement among professionals.
The end of single-tool loyalty
Analysts quoted in the coverage argue that the more important trend is not which assistant is ahead this month but the erosion of the idea that a person or company should rely on one AI tool. Model quality shifts with each release, pricing changes and services can be restricted or withdrawn, as OpenAI’s decision the same week to shut down its Sora video app illustrated.
That has implications for the job market. Employers are increasingly looking for people who can work across platforms and optimize AI workflows, including skills described as AI-native development and so-called vibe coding, in which developers direct AI agents in natural language. Familiarity with one product is becoming less valuable than the ability to choose and combine tools for a given task.
Implications for organizations
For companies, the episode is an argument for flexibility: building systems that can switch between model providers, avoiding deep lock-in to a single vendor’s interface and maintaining an AI strategy that does not depend on any one company’s roadmap. Whether the current migration toward Claude holds will depend on the next round of model releases from both companies, but the readiness of users to move has already been demonstrated.
