Why is Meta spending so much on AI infrastructure?

Meta's primary goal is to use AI to improve its advertising capabilities. CEO Zuckerberg said the company wants to let any business specify their objective (like selling something or acquiring a customer) and their budget, then let AI handle the rest. Advertising is critical: ad sales were $55 billion（約8.8兆円） in Q1 and represented 98% of Meta's entire revenue.

How much did Meta spend on capex last year?

Meta spent $72 billion（約12兆円） on capital expenditures in the prior year. The planned $125 billion（約20兆円） to $145 billion（約23兆円） for 2026 would be roughly double that amount.

How has Meta's advertising performed recently?

In Q1 (ended March 31), Meta reported a 19% year-over-year increase in ad impressions and a 12% rise in average price per ad. Overall revenue rose 33% compared to Q1 of the prior year, the fastest growth rate since Q3 2021.

Key takeaway

Meta Platforms plans to spend $125 billion（約20兆円） to $145 billion（約23兆円） on AI infrastructure in 2026, about double last year's $72 billion（約12兆円） outlay. The company is betting almost entirely on AI-powered advertising: founder Mark Zuckerberg said the goal is to let businesses specify their objectives and budgets while AI optimizes results, with the hope that improved ad productivity will expand advertising's share of global GDP. While Meta's Q1 ad revenue grew 33% year-over-year—its fastest pace since Q3 2021—investors remain cautious, with the stock down sharply in 2026.

3 Key Points

What happened
Meta Platforms announced plans to spend $125 billion（約20兆円） to $145 billion（約23兆円） on capital expenditures in 2026, mostly for AI infrastructure—roughly double the $72 billion（約12兆円） figure from last year.
Why it matters
The spending surge is driven by a single priority: using AI to improve Meta's advertising capabilities. CEO Mark Zuckerberg stated the goal is to let any business specify what they want to achieve and how much they'll pay per result, with AI handling the rest. Ad sales totaled $55 billion（約8.8兆円） in Q1 (ended March 31), representing 98% of the company's entire revenue, so investors will scrutinize whether the capex delivers returns.
What to watch
Meta reported a 19% year-over-year increase in ad impressions and a 12% rise in average price per ad during Q1, lifting revenue 33% compared to Q1 2025—the fastest growth rate since Q3 2021. However, the stock is down 15% in 2026 (as of June 29) and 29% off its record, suggesting investor concern about whether AI spending will justify the cost.
