ChatGPT remains the clear leader in AI awareness, trial, usage, and subscription. But Gemini finishes just behind ChatGPT on awareness and converts trial into regular usage just as well. And despite Claude’s much smaller audience, its users show strong engagement and are most likely to subscribe. These leaders are setting the pace—and increasingly defining how AI advertising works.

Key Question: Which genAI platforms are most effective at turning consumer awareness into trial, repeat usage, and paid subscriptions?

Key Stat: No single AI platform leads every stage of the conversion funnel. ChatGPT converts 59.9% of people who have heard of it into first-time users, while Gemini leads in trial-to-monthly usage and Claude in converting users into subscribers.
