Investing.com — ChatGPT maintained consistent share gains in global and U.S. search markets in July, according to Wells Fargo’s August 2025 Consumer AI Agent Monitor.
The AI language model increased its global search instance share by 60 basis points month-over-month and accelerated its U.S. share growth to 100 basis points, Wells Fargo said.
“ChatGPT’s global share gain moderated slightly in July to +60bps m/m (June +80bps), but accelerated in the US to +100bps m/m (June +70bps),” the note said.
This steady expansion is said to reflect ChatGPT’s ongoing ability to capture users amid evolving search behaviours.
Meanwhile, the bank said Google’s global usage instance growth improved to about 10% year-over-year in July, up from roughly 8% over the prior four months.
Despite this growth, Google (NASDAQ:GOOGL) faced accelerated U.S. share loss, highlighting the competitive pressure from AI agents like ChatGPT.
Wells Fargo noted, “Consistent share loss to ChatGPT likely necessitates more aggressive action from Google.”
The research also pointed out that Google’s Gemini AI search share remained steady at 0.9%, which Wells Fargo deemed “disappointing” given the AI market’s rapid growth.
Currently, AI agents hold 12.1% of the global search share, while traditional Google search accounts for 88%, down 10 percentage points from July 2024.
Looking ahead, Wells Fargo expects Google to integrate its AI Mode fully into the main search bar by early 2026, aiming to respond to the growing threat posed by ChatGPT and other AI tools.
Overall, Wells Fargo sees the latest trends as “broadly consistent” with prior months and anticipates accelerated share gains following major OpenAI launches such as GPT-5.
