Alphabet’s AI-powered search now reaches 2.5 billion users monthly

Alphabet ↗ 1.05% CEO Sundar Pichai revealed at Google I/O 2026 in May that AI Overviews — the Gemini-powered summaries displayed atop Google Search results — now reaches more than 2.5 billion monthly users, making it the most widely distributed AI product in the world.

Scale Drives Ad Revenue

The milestone, confirmed in a Google blog post from the event, underscores how deeply AI has become embedded in everyday search behavior. Pichai also disclosed that AI Mode, a more conversational search interface, has crossed 1 billion monthly users, while the standalone Gemini app grew to 900 million monthly active users by the time of the conference.blog+2

That massive engagement is translating directly into revenue. Alphabet reported $81 billion in advertising revenue in the second quarter of 2026, up 14% year over year, according to an analysis by The Motley Fool published Friday. "Our AI investments are redefining what's possible across every part of our business," Pichai said on the company's Q2 earnings call.finance.yahoo

Users who interact with AI features search more frequently, the company said, driving record query volumes and generating behavioral data that improves both user experience and ad targeting.aol

Infrastructure Investment at Scale

The user growth comes with enormous infrastructure costs. Alphabet now processes more than 3.2 quadrillion tokens per month, a sevenfold increase from the prior year. Capital expenditures reached $136 billion over the trailing 12 months, and the company has forecast $180 billion to $190 billion in capex for the full year 2026.cryptobriefing+1

Cash from operations climbed to $185 billion on a trailing-12-month basis, supported by advertising growth, improving Google Cloud margins, and lower per-query costs for AI-generated responses.finance.yahoo

Competitive Context

The numbers place Alphabet well ahead of rivals in AI distribution. Meta ↗ 0.75% is integrating its own AI assistant across its apps, while Microsoft ↗ 0.43% has embedded Copilot into Office and Windows. Apple ↘ 0.63% has taken a more measured approach with Apple Intelligence.cryptobriefing

Alphabet's stock is trading roughly 16% below its prior high as investors weigh heavy spending against near-term profitability. But as Pichai told investors in June, the company is "continuing to incorporate more frontier capabilities into Search with agents, personal intelligence, and notebooks".finance.yahoo
