Important Note: Analytics platforms (Google Analytics, Adobe) often adjust their reporting to reflect changes in AI referrals. In July 2026, we updated historical data to take these changes into account. OpenAI/ChatGPT data, which accounts for the majority of AI referrals, was impacted, which in turn impacted historical market share data.
Total Search Dominance Index
In July 2026, Google's market share increased to 87.4% from 87.0% in the previous month. Bing's share dipped slightly to 5.8%, while the "All AI" category remained steady at 1.4% of the total search market. This indicates a stable market in which Google maintains its lead, and AI search remains a small, consistent fraction of the overall search landscape.
AI-Specific Search Index
By transforming into a "self-contained answer engine," Google aims to keep users within its ecosystem, countering competitors like ChatGPT, which dominates the AI search niche with a 93% share. ChatGPT faced intense pressure in early 2026. Google executed a strategy to make Gemini the "connective tissue" of its entire ecosystem, releasing the efficient Gemini 3.5 Flash model in May. Anthropic launched its highly anticipated Fable 5 and Mythos 5 models on June 9, only to have them suspended three days later by the U.S. government, creating significant market uncertainty

The long-term trend shows that after a dip in early 2026, ChatGPT's market share has stabilized at a high level. While competitors like Gemini, Claude, and Perplexity hold much smaller shares, their presence contributes to a competitive environment where users show a willingness to try different platforms, especially when the leader's share experiences fluctuations.
