Microsoft appears to be falling behind in the AI race. According to new figures from analytics company SimilarWeb (spotted by Windows Latest ), Copilot accounts for only 1.1 percent of the market share on the web. The market is unsurprisingly dominated by ChatGPT, which has 64.5 percent, while Google’s Gemini has grown significantly to 21.5 percent. A year ago, the situation was very different. Back then, ChatGPT had 86.7 percent of the market with Gemini at 5.7 percent. During this same period, Copilot has fallen from 1.5 percent (back then) to 1.1 percent (now). Even smaller players in the AI space have climbed ahead of Microsoft’s ailing AI assistant, including Elon Musk’s Grok with 3.4 percent and both Claude and Perplexity with 2 percent each. Note, however, that these figures by SimilarWeb only apply to web traffic. It’s unclear how popular Copilot is on Windows 11, as Microsoft doesn’t publish any user figures. However, if user sentiment is a reliable measure, it can’t be doing that much better.
