Gaining traction Google reveals sky-high Gemini usage numbers in antitrust case Google revealed in court that Gemini now sees 350 million monthly users.

During day three of Google's antitrust remedies trial, the company presented a slide showing that Gemini reached 350 million monthly active users as of March 2025. That's a massive increase from last year, showing that Google is beginning to gain traction among competing chatbots, but Google's estimation of ChatGPT's traffic shows it still has a long climb ahead of it. The slide was presented during the testimony of Sissie Hsiao, who until recently was leading Google's Gemini efforts. She was replaced earlier this month by Josh Woodward, who also runs Google Labs. The slide listed Gemini's 350 million monthly users, along with daily traffic of 35 million users. These numbers represent a huge increase for Gemini, which languished in the tens of millions of monthly users late last year. Gemini's daily user count at the time was a mere 9 million, according to Google. Since then, Google has released its Gemini 2.0 and 2.5 models, both of which have shown demonstrable improvements over the previous iterations. It has also begun adding Gemini features to more parts of the Google ecosystem, even though some of those integrations can be more frustrating than useful. Despite the uptick in Gemini usage, Google is still far from catching OpenAI. Naturally, Google has been keeping a close eye on ChatGPT traffic. OpenAI has also seen traffic increase, putting ChatGPT around 600 million monthly active users, according to Google's analysis. Early this year, reports pegged ChatGPT usage at around 400 million users per month. There are many ways to measure web traffic, and not all of them tell you what you might think. For example, OpenAI has recently claimed weekly traffic as high as 400 million, but companies can choose the seven-day period in a given month they report as weekly active users. A monthly metric is more straightforward, and we have some degree of trust that Google isn't using fake or unreliable numbers in a case where the company's past conduct has already harmed its legal position. While all AI firms strive to lock in as many users as possible, this is not the total win it would be for a retail site or social media platform—each person using Gemini or ChatGPT costs the company money because generative AI is so computationally expensive. Google doesn't talk about how much it earns (more likely loses) from Gemini subscriptions, but OpenAI has noted that it loses money even on its $200 monthly plan. So while having a broad user base is essential to make these products viable in the long term, it just means higher costs unless the cost of running massive AI models comes down.
