Market dominance is rarely permanent even for a company that started the race. OpenAI currently faces a sobering reality as its primary rival begins to eat into its market share with alarming speed. Data from late 2025 reveals that traffic to ChatGPT declined while Google’s Gemini platform surged following a major product release. The release of Gemini 3 Pro appears to be the catalyst that finally shifted user momentum away from the industry leader.
• Gemini traffic rose 28.4% month-over-month in December
• ChatGPT traffic dropped 5.6% during the same period
• The shift followed the November release of Gemini 3 Pro
Year-over-year statistics paint an even more drastic picture of how the landscape is evolving. Web traffic for ChatGPT grew by a respectable 49.5% compared to the previous year. Gemini, however, exploded with a staggering 563.6% growth rate over the same timeframe. These figures suggest that while the incumbent is still growing, the challenger is accelerating at a pace that could eventually close the gap.

• Gemini traffic exploded with 563.6% growth
• The data highlights shifting tides in the AI race
OpenAI retains a healthy lead in total volume despite these trends. ChatGPT attracted 5.5 billion visitors in December compared to 1.7 billion for Gemini. Other competitors such as DeepSeek, Grok, and Claude trailed significantly with fewer than 400 million visitors each. The sheer size of the lead means that Google still has a mountain to climb before claiming the top spot.
• ChatGPT led with 5.5 billion visitors in December
• Gemini followed with 1.7 billion visitors
• Competitors like DeepSeek and Grok trail significantly
Google is leveraging its massive ecosystem advantage to drive these numbers. The tech giant integrates its models directly into search products that billions of people already use daily. Gemini 3 Pro also received praise for superior coding abilities and creative visual features compared to previous versions. OpenAI faces the difficult task of convincing users to leave a platform they already inhabit to use a standalone tool.
• Google integrates AI into its dominant search products
• Gemini 3 Pro was lauded for coding and visuals
• OpenAI must convince users to switch platforms
The pressure has reportedly caused internal alarm within OpenAI. CEO Sam Altman allegedly declared a code red to prioritize product development in response to the competitive threat. He later admitted that the rival launch identified specific weaknesses in their strategy that required immediate attention. Both companies are now locked in a tight race that includes expanding into new territories like image generation.
