Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) CEO Sundar Pichai shared a notable statistic at the company's June 2026 investor presentation: AI Overviews now has 2.5 billion monthly users. That kind of reach makes Google Search one of the most powerful monetization channels for artificial intelligence (AI).
"Our AI investments are redefining what's possible across every part of our business," Pichai said on the company's second-quarter earnings call.

The massive reach helps explain why Alphabet generated $81 billion in ad revenue in the second quarter, up 14% year over year. The company's ability to turn Search into massive cash flow -- and reinvest it into chips and data centers -- is why Alphabet remains a compelling way to ride AI's growth.

AI has supercharged Google's advertising revenue
The strong growth in ads shows that high engagement with AI Overviews is improving advertiser returns. The company revealed that users who engage with AI features search more often, helping to drive record query volumes. The growth in search queries generates more behavioral data to improve user experiences and ad quality, which fuels the revenue engine.
The momentum in advertising is pushing Alphabet to accelerate the deployment of Gemini -- the AI that powers Overviews -- deeper into its advertising business. That spells more growth.
The company is also continuing to push the boundaries of what's possible with Search. "We are continuing to incorporate more frontier capabilities into Search with agents, personal intelligence, and notebooks," Pichai said during the Q2 earnings call.
These are meaningful signals for investors, since advertising still accounts for about two-thirds of Alphabet's total revenue.
A solid stock for the long term
The scale of Alphabet's advertising revenue is providing enormous resources for AI infrastructure, which isn't cheap. Alphabet's capital expenditures totaled $136 billion over the trailing 12 months, and management expects another notable increase in 2027. That pace of spending will pressure near-term free cash flow.
The stock is currently trading 16% below its prior high, as market participants weigh the cost of AI on near-term profitability. But those same investments are also strengthening Search and potentially widening Alphabet's moat.
Importantly, Google's cash from operations has climbed to $185 billion on a trailing-12-month basis, supported by growing advertising revenue, improving Google Cloud margins, and lower costs to generate AI Mode responses in Search.
Alphabet is demonstrating that its AI investments are translating into strong revenue growth while also improving compute efficiency, which could be beneficial for long-term free cash flow growth. This is all possible because it has a massive user base to monetize. This puts Google in a strong position to deliver long-term returns to shareholders.
