DuckDuckGo Sees 30% Install Spike After Google I/O 2026 AI Search Push

• Overall U.S. installs grew by an average of 18.1% week-over-week from May 20 through May 25, sustaining growth for six consecutive days. The single-day peak came on May 25, with a 30.5% increase .
• iOS installs led the charge, averaging 33% week-over-week growth and hitting a peak of 69.9% on May 25 . This suggests a particularly strong reaction among iPhone and iPad users .
• AI-free search portal traffic also rose sharply. Visits to noai.duckduckgo.com, a version of the search engine that disables all AI-assisted answers and features by default, jumped an average of 22.7% week-over-week .

The increases persisted through the Memorial Day long weekend, indicating the shift wasn't just a momentary reaction but a sustained behavioral change .

The core complaint: ‘Force-feeding AI’ with no opt-out

Weinberg didn't mince words about why users were leaving. His central criticism was that Google's AI-first redesign left users with no meaningful way to decline the new features.

In a statement, he said: “Google is force-feeding AI with no way to opt out. As a result, their results are getting worse, not better” . His argument centered on user control—something DuckDuckGo immediately used to differentiate itself. The company positioned its search experience as one that "puts users in charge and allows them to decide how much or how little AI they want" . The noai.duckduckgo.com page was offered as the concrete proof point: an entirely AI-free search experience by default, without requiring users to navigate complex settings .

Tying the user exodus to the antitrust case

Weinberg went a step further, connecting the immediate user backlash to the broader structural issues raised in the U.S. government's antitrust case against Google. During the trial, Weinberg testified that Google's exclusive default-search contracts—worth billions of dollars annually to companies like Apple—blocked DuckDuckGo from competing fairly .

In the context of the I/O 2026 aftermath, Weinberg argued that this market reality amplified the harm. Google's dominance, built and maintained through those exclusionary deals, meant that millions of users had no easy default pathway to escape an AI search experience they didn't ask for and couldn't opt out of . The I/O announcements, by generating widespread media coverage, finally broke through that default barrier and drove users to seek alternatives .

DuckDuckGo framed the moment as a convergence of two harms: the immediate frustration of an unwanted AI overhaul and the long-standing antitrust damage that made switching feel impossible for most users. By positioning itself as both the privacy-first and AI-optional alternative, DuckDuckGo turned a week of search-industry turbulence into its most significant public growth narrative in years.
