New report shows ChatGPT retains category leadership, Claude emerges as a fast-rising challenger, and women over-index on mobile AI assistant usage

RESTON, Va., June 2, 2026 — Comscore, a global leader in measuring and analyzing consumer behaviors, today released its first AI Intelligence Report for 2026, which showed the scale of breakout growth from Anthropic’s Claude platform. The Q1 report based on Comscore’s panel data, revealed that Claude recorded 1,858% growth in desktop conversations between March 2026 and October 2025. While ChatGPT continues to lead the AI assistant category up 55% year over year, the report shows consumers are expanding their use of a wider range of options.

The report also found that women are emerging as key drivers of mobile AI adoption across major generative AI tools. According to the data, women posted mobile index scores of 113 for ChatGPT in March 2026, 123 for Copilot, and 118 for Gemini, while men across the same platforms in the same period had scores of 87, 77, and 82, respectively. These findings further highlight the influence AI is having on a consumer’s on-the go and day to day behavior.

“Comscore is providing some of the industry’s first visibility into AI-influenced intent behavior, as AI rapidly becomes the prime gateway for consumer awareness, attention, and decision-making,” said Smriti Sharma, Executive Vice President of Analytics and Managing Director of Custom IQ at Comscore. “For brands and publishers, understanding how AI shapes discovery, which sources it references, and how those interactions translate into measurable business outcomes will be increasingly critical in the evolving digital landscape.”
