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.
