Open AI Vs Google; ChatGPT edges past 10% of market share in June, search slips to 88.5%

ChatGPT’s rise in consumer usage continued in June, crossing a key milestone with more than 10% share of global usage instances, according to a new note from Wells Fargo.

“ChatGPT share gain modestly accelerated in June, surpassing 10% share (+80bps m/m), while traditional search fell to 88.5%,” the analysts wrote.

This is said to mark an incremental acceleration from May, when ChatGPT gained 70 basis points.

The pace in June was also broadly in line with the average monthly gains seen in the first half of 2025, excluding April’s record surge, according to the bank.

Meanwhile, traditional search platforms, still dominated by Google (NASDAQ: GOOGL), continued to cede ground.

“Traditional search instance share declined to 88.5% (-90bps m/m),” Wells Fargo said, noting that Google has now lost 6.6 percentage points of market share year to date.

Despite this, Google’s own usage growth remained steady. “Growth of Google usage instance across search and Gemini remained stable in June at HSD% y/y,” Wells Fargo wrote, although it added that the company “continues to observe share loss amid strong user adoption of ChatGPT.”

Google’s Gemini AI platform saw a small increase as well. “Gemini’s usage share saw similar modest gain of ~10bps, consistent with May, reaching 0.7% of global usage share,” the analysts said.

Looking ahead, Wells Fargo forecasts that Google will show a modest improvement in its second-quarter earnings.

“Based on improving growth in Google’s usage instances in 2Q vs. 1Q, we forecast 2Q reported Google search paid clicks growth to accelerate to +3.5% y/y from 1Q’s low of +2% y/y.”
