For all the attention on OpenAI‘s ChatGPT and Alphabet Inc‘s (NASDAQ:GOOGL) (NASDAQ:GOOG) Google Gemini, one of the fastest-moving stories in generative AI may belong to a much smaller player.
Anthropic‘s Claude has quietly increased its share of global generative AI website traffic from 1.6% a year ago to 9.2% in June 2026, according to new data from Similarweb. That’s a gain of nearly 500%, allowing Claude to leapfrog rivals like Grok, DeepSeek, Microsoft Corp‘s (NASDAQ:MSFT) Copilot and Perplexity in the race for user attention.
Claude Is Winning The Battle Below The Top Two
The AI traffic leaderboard still belongs to ChatGPT, which held a commanding 52.7% share in June despite slipping from 76.4% a year earlier. Google’s Gemini has emerged as the clear No. 2, climbing from 9.1% to 27.8% over the same period.
But the real surprise sits just below them.
