ChatGPT’s Monopoly Fades: Global traffic share drops to 64% as Gemini climbs above 21%
ChatGPT loses 22% traffic share in 2025 as Gemini gains similar ground.
As the global artificial intelligence race intensifies, new website traffic data reveals a sharp shift in user preference between ChatGPT and Google’s Gemini. While OpenAI’s ChatGPT once dominated the generative AI space, 2025 trends indicate that Google’s AI platform is rapidly gaining ground, raising concerns within OpenAI about its long-term competitive position.
According to data shared by web analytics firm Similarweb, ChatGPT’s global website traffic share declined from 86.7 percent to 64.5 percent over the past 12 months. In contrast, Google’s Gemini surged from just 5.7 percent to 21.5 percent during the same period, marking one of the most dramatic shifts in the generative AI market to date.
The data also shows emerging players making modest inroads. Elon Musk-backed Grok captured 3.7 percent of traffic, while DeepSeek reached 3.4 percent despite being virtually unknown before 2025. Anthropic’s Claude posted marginal growth, while Microsoft’s Copilot saw a slight decline, reflecting its reliance on deep integration within Windows and Microsoft 365 rather than standalone web usage.

Analysts note that the traffic war is most significant for OpenAI and Google, as both companies aggressively promote their AI tools through dedicated websites. Other platforms rely more on ecosystem integrations—Grok through X, Copilot via Windows, and Claude primarily through mobile and enterprise applications—making direct web traffic comparisons less critical for them.
The steep decline in ChatGPT’s web traffic is believed to be a key factor behind reports that OpenAI CEO Sam Altman declared a “code red” internally in November 2025. Reports suggested that non-ChatGPT projects were paused after Google released Gemini 3 Pro, which reportedly outperformed GPT-5.1 across several benchmarks, intensifying competitive pressure.
Although OpenAI responded by launching GPT-5.2 in December, the challenge remains significant. Google’s vast distribution network across Search, Android, and Workspace apps gives Gemini a structural advantage. With the open web once serving as ChatGPT’s strongest battleground, the ongoing migration of users toward Gemini signals an urgent need for OpenAI to accelerate innovation and differentiation to retain its leadership in the AI landscape.
