Comscore Reports ChatGPT Market Share Decline as Gemini and Claude Gain Ground

Comscore's latest AI Intelligence Report indicates a significant shift in the generative AI landscape. ChatGPT's market share, specifically its prompt share, has reportedly fallen from 70% to 50%. This decline coincides with substantial gains by Google's Gemini and Anthropic's Claude, which are increasingly capturing user attention. Gemini has emerged as the second-largest bot referral to websites, while Claude has seen a dramatic increase in visits. The data suggests a broader adoption of AI tools beyond ChatGPT, leading to a more fragmented discovery ecosystem across desktop and mobile platforms.
