ChatGPT Rebounds to 56% Market Share as Gemini's Growth Stalls

OpenAI's ChatGPT has regained momentum in generative AI web traffic, climbing to 56% of the market after sliding to lows near 53%, while Google's Gemini faces its first sustained decline in over a year, dropping to 25% market share as product momentum falters. The shift marks a significant reversal in the competitive dynamics of consumer AI, breaking Gemini's 12-month winning streak that had seen the Google-backed platform surge from under 6% a year ago to nearly 27% at its peak in mid-2026.
