Summary

A recent market report indicates that ChatGPT's share of AI chatbot web visits significantly declined from approximately 76% in early 2025 to about 55% by spring. This shift occurred despite continuous product improvements, suggesting factors beyond quality are driving market dynamics. Google's Gemini has concurrently risen to roughly 27% with triple-digit growth, while Anthropic's Claude saw an impressive 306% increase in a single quarter, albeit from a smaller base. DeepSeek and Grok hold smaller shares. The analysis, based on Momentic's reading of Similarweb data, highlights that competitors are gaining ground primarily through built-in distribution channels, such as pre-installation in operating systems, search bars, and enterprise software, rather than superior model performance. This trend suggests that ownership of "front doors" is a critical determinant in the consumer AI market.

Key takeaway

For AI Product Managers evaluating market strategy, recognize that distribution channels are currently more critical than raw model quality for user acquisition. Your product's success increasingly depends on being a default option within existing ecosystems, not just being the "best." Focus on securing pre-installation deals, integrating into widely used platforms, or developing proprietary hardware to become a "front-door" AI. Otherwise, even superior models risk losing market share to competitors with built-in access.

Key insights

In consumer AI, distribution ownership, not just model quality, is the primary driver of market share.

Principles

• Default access beats deliberate choice.
• Built-in distribution compounds usage.
• "Front-door" ownership dictates market.

Method

To predict AI market winners, apply the "front-door test": assess if an AI assistant is sought out or arrives by default, and who owns its embedded surfaces.

In practice

• Embed AI into existing user workflows.
• Prioritize platform deals for distribution.
• Develop proprietary hardware or OS integration.

Topics

• AI Market Share
