Why Market Share is a Misleading Metric for AI Success

Analyzing mobile usage data through December 2025, the study identifies three clear paths to sustainability: scale, ecosystem integration, and premium differentiation. ChatGPT currently functions as the scale leader, commanding 78.4% of daily active users. Its challenge lies in converting that massive reach into durable, long-term profit. Conversely, Google Gemini acts as an ecosystem player. While it holds a 12.5% share of daily active users, its primary value is captured through Google’s broader suite of products rather than direct app revenue.

Claude occupies the third lane: the premium niche. Despite a small 0.5% share of daily active users, it generates significantly higher revenue per user—roughly 40 times that of Gemini and three times that of ChatGPT. This divergence suggests that the AI market is not a zero-sum horse race. The researchers examined 15 major model launches between 2023 and 2025 and found that new releases generally expand the total market rather than cannibalizing rivals. For executives, the core takeaway is that success hinges on aligning a business model with structural advantages rather than chasing a single, universal standard.
