More than three years into the generative artificial intelligence boom, Google has defied the many skeptics who thought ChatGPT would be the search giant's death knell. But cracks are forming in its core business.

According to a June 23, 2026 report by CNBC, rival search engines and chatbots are steadily eroding the edges of Google's dominance as more people turn to conversational AI to find information. The shifts are still small in percentage terms, but they point to the most serious competitive challenge Google's search business has faced in years. For more context on this story, see our ongoing AI trends.

Competitors Gain Traction

The data cited by CNBC tells a story of incremental but meaningful change. Privacy-focused search engine DuckDuckGo is seeing install rates jump by as much as 40 percent a week, with installs up as much as 75 percent since Google's I/O developer conference in May. Microsoft's Bing, boosted by its integration of AI, reached 1 billion users for the first time last quarter.

Over the past month, Google's search engine traffic is down more than 1 percent, according to web analytics firm Ahrefs, while ChatGPT traffic is up over the same period. ChatGPT, which recently surpassed 1 billion monthly active users, consistently ranks as the top free app on Apple's iOS. Anthropic's Claude sits eighth, one spot behind Google's own Gemini.

Still Dominant, but Pressured

Google still controls roughly 90 percent of the search market, and the company's broader financial position remains formidable. Its stock price has more than doubled over the past year, and first-quarter revenue growth was the fastest for any period since 2022. Advertising still accounts for about three-quarters of Google's revenue, and the sky-high margins from those ads help fund costly bets like Waymo and space-based AI, along with spending close to $200 billion on AI infrastructure.

But the AI concern persists. The threat is twofold: that Google loses its dominance as users migrate to chatbots, and that, in trying to compete, it cannibalizes search in favor of a new way of finding information that does not yet have a proven digital advertising model.

A Search Box Redesigned

Google is not standing still. At its annual developer conference in May, the company said it would redesign the search box for the first time in 25 years, placing an AI Mode button directly inside the box and pushing the traditional search button below it.

"This is the biggest upgrade to our iconic search box since its debut over 25 years ago," Elizabeth Reid, who oversees Google's search organization, said at the event. The company's image generation tool, Nano Banana, is also available from the search box, and on the Google Search mobile app, a large AI Mode button is now nearly the same size as the regular search box.

A Talent War and a Stock Slide

The competitive pressure extends beyond user habits to talent. In recent weeks, Google has lost senior AI leaders to rivals racing toward initial public offerings. Noam Shazeer, a vice president of engineering and co-lead of Gemini, announced he was leaving to join OpenAI. John Jumper, a DeepMind vice president, engineering fellow, and 2024 Nobel chemistry laureate, said he was leaving for Anthropic.

Alphabet's stock had its worst day in more than a year on the news, dropping 5 percent. Analysts at Jefferies sought to downplay the departures, writing that they did not read them as a signal that Google is doing less with AI, "but rather as another data point in an industry-wide war for talent in which frontier labs are aggressively bidding."

A Backlash Against AI Search

Notably, some of the traffic shifting away from Google is moving toward non-AI alternatives rather than chatbots. Earlier in June, DuckDuckGo launched a no-AI search experience with browser extensions that allow users to default to a version of the search engine stripped of AI-generated results.

A Pew Research Center study published in March found that about half of Americans felt that AI in their daily lives made them more concerned than excited. Navigating the internet without AI is, for some, a coping mechanism.

"A lot of people use Google because Google is like the front page of the internet, but they want to go on these journeys and do the clicking and searching themselves and make their own decisions," said Lily Ray, vice president of search engine optimization and AI search at marketing firm Amsive.

Google now faces a delicate balancing act: lean hard enough into AI to keep users from defecting to ChatGPT and Claude, without alienating the audience that still wants a traditional search experience, and without undercutting the advertising business that funds everything else. After more than two decades of near-total dominance, the company is, for the first time, searching for that balance under genuine pressure.
