In the constantly evolving world of artificial intelligence, 2025 marks a pivotal year for language generation tools, with notable changes in market share distribution. While ChatGPT, long dominant, sees its position erode, Google Gemini is gradually establishing itself as a major player. What do these developments mean for the future of the sector?
The 3 key facts not to miss
- ChatGPT saw its market share drop from 87.2% to 68% in one year.
- Google’s Gemini experienced growth in its traffic share, reaching 18.2% in 2025.
- The language model market is fluid, with rapid changes in leadership.
Evolution of the language model market
According to SimilarWeb data, the distribution of traffic among the main generative AI services has seen notable changes over the past twelve months. In 2024, ChatGPT largely dominated the sector with 87.2% of the traffic, but this figure dropped to 68% at the beginning of December 2025. This decline illustrates a shift in user preferences towards competing alternatives, mainly Google’s Gemini.
The rise of Google Gemini
Gemini, Google’s generative AI tool, gained significant ground in 2025. Rising from 5.4% traffic share at the end of 2024 to 18.2% a year later, Gemini managed to capture attention thanks to its superior performance in various benchmarks. Designed to provide direct answers and avoid unnecessary flattery, this tool has won over users with its efficiency.
The CEO of Google DeepMind, Demis Hassabis, praised the progress made by the Gemini team, highlighting the impact of this new version in the AI landscape.
Outlook for the generative AI market
The language model market remains dynamic and open to rapid changes. Besides Google and OpenAI, other players, such as Grok backed by Elon Musk, show an upward trend. However, some, like DeepSeek, are losing ground. Nonetheless, the entire market remains adaptable, and user preferences can quickly evolve based on the new capabilities of the models offered.
ChatGPT: A historical player in transition
ChatGPT, developed by OpenAI, has long been a reference in the field of language models. Initially launched in 2019, it established itself thanks to its natural language processing capabilities, attracting a wide audience with its user-friendly interface and relevant responses.
Despite the recent decline in its market share, ChatGPT continues to evolve, with OpenAI seeking to enhance its features to remain competitive against the emergence of new players like Google Gemini. The future of ChatGPT will depend on its ability to adapt to changing user expectations and innovate in a rapidly changing market.
