For the first time, ChatGPT holds less than half of the AI assistant market, according to a report highlighted by Gizmodo. The milestone marks a symbolic turning point for OpenAI, whose product has dominated the conversational AI space since its late-2022 launch.
Meanwhile, Anthropic's Claude is carving out a different kind of advantage. According to Forbes, Claude generates more revenue per user than ChatGPT — suggesting that while OpenAI still commands the largest raw user base, Anthropic may be winning on monetization. Users who pay for Claude appear to spend more, a signal that the product is resonating with higher-value customers willing to open their wallets.
The two findings together paint a more complicated picture of the AI assistant race than raw download or signup numbers typically suggest. Market share and revenue efficiency are different games, and different companies are winning each one.
For everyday users, the competition is good news: it means both OpenAI and Anthropic have strong incentives to keep improving their products. For investors and the broader tech industry, it raises a pointed question about which metric matters more — reach or revenue — as these companies race toward profitability.
The erosion of ChatGPT's majority share matters because it signals the AI assistant market is genuinely competitive now, with real consequences for which company ultimately has the resources to build the next generation of the technology.
