ChatGPT Recovers AI Chat Market Share to 55.5%

According to Similarweb, a web traffic analysis service, ChatGPT has recorded a 55.5% share of website visits in the AI chatbot market, recovering its share. Meanwhile, Google's Gemini showed temporary momentum in catching up, but that momentum did not last long.

However, it is important to note that this figure covers only access via web browsers and does not include usage through smartphone apps or desktop-only clients. It does not accurately reflect actual usage patterns and should be understood only as figures from the perspective of website access.

When compared to the same period last year, the shift in the competitive landscape becomes clearer. ChatGPT's share has declined significantly from 73.3% to 55.5%, and the growth of other services is eroding its lead. Gemini has doubled its share from nearly zero, while Anthropic's Claude has expanded its share by approximately five times. Looking at the numbers alone, ChatGPT's overwhelming first-place position remains unchanged, but the presence of those chasing from behind is steadily increasing.

Behind this trend lies the rapid expansion of the overall AI chatbot market. As the market itself grows, later entrants also find it easier to acquire users. Gemini is advancing integration with Google services, while Claude is promoting usage through APIs for developers and enhancing features for business customers, with each service positioned as cutting into the market with different strengths.

For ChatGPT, the recovery in share is a positive development. However, the narrowing of its lead compared to the previous year also indicates that a transition from a monopoly situation to a competitive market with multiple players is steadily progressing. Going forward, the key question will be how each company differentiates itself and promotes user retention.

It is worth noting that the exclusion of mobile apps from this survey is an important limitation for interpretation. Given the increasing usage share from smartphones, relying solely on web access to discuss the entire market has its limitations. The perspective of combining multiple indicators to understand competitive conditions is becoming increasingly important for reading future market changes.
