Big Tech is on a spending spree, forecast to drop a staggering $650 billion on artificial intelligence (AI) in 2026 alone—and that’s just for Alphabet, Meta, Microsoft, and Amazon. The companies are ramping up their investment in an increasingly competitive, high-stakes arms race, pouring hundreds of billions into massive data centers and semiconductors, in hopes of establishing a long-term strategic advantage in their quest to dominate the future of technology.
With all four multinational corporations reporting earnings within the last week, Wall Street’s reaction may be an indication that investors are increasingly worried about the large spend, and relative payoffs, from the AI investments.
The spending also coincides with mass layoffs across the tech industry. Those layoffs—originally attributed to AI being able to do the jobs of human workers—are now being seen by critics as an excuse for companies to reduce head counts so that they can divert spending from workers to building and powering AI data centers, among other things.
Here is a look at some at the numbers as we break down Amazon’s, Meta’s, Microsoft’s, and Alphabet’s AI spend for 2026.
Amazon 2026 AI spend
Reporting fourth-quarter earnings on Thursday, Amazon said it was pouring $200 billion in capital expenditures into AI this year. News of that, plus the fact that it missed its first-quarter operating income forecast due to the massive spend, sent shares of the stock down 10% in early morning trading on Friday. At the time of this writing, shares of the e-commerce and cloud giant (Nasdaq: AMZN) were down over 6% in afternoon trading.
“With such strong demand for our existing offerings and seminal opportunities like AI, chips, robotics, and low-Earth-orbit satellites . . . we anticipate strong long-term return on invested capital,” Amazon CEO Andy Jassy said in the earnings release.
Alphabet 2026 AI spend
Alphabet, Google’s parent company, said in Wednesday’s earnings report that it estimated AI spending would hit $175 billion to $185 billion this year.
Despite its recent performance and positive earnings report, Wall Street reacted with caution, sending shares of Alphabet Inc. (Nasdaq: GOOGL, GOOG) down nearly 2% at the time of this writing on Friday afternoon.
Meta 2026 AI spend
By comparison, Meta’s capital expenditure for AI lags behind, but is significantly higher and more aggressive than just one year ago.
The company—which owns and operates Facebook, Instagram, Threads, Messenger, and WhatsApp—said it was hiking capital investment for AI development by 73% in 2026, to between $115 billion and $135 billion.
For some context, at the beginning of 2025, Meta CEO Mark Zuckerberg had said the social technology company planned to invest between $60 billion and $65 billion, showing just how quickly this AI arms race has ramped up.
Shares of Meta (Nasdaq: META) were trading down less than 2% at the time of this writing on Friday afternoon.
Microsoft 2026 AI spend
Finally, Microsoft (Nasdaq: MSFT)—whose shares were up 1% Friday afternoon, bucking the trend of the three other Big Tech stocks—is on course for AI capital expenditures of $145 billion by the end of its fiscal year in July, according to Yahoo Finance.
The stock is down 41% from its October high.
The company recently reported second-quarter 2026 earnings, including $81.3 billion in revenue (up 17% year over year) and diluted earnings per share (EPS) of $4.14 (up 24% year over year).
“We are only at the beginning phases of AI diffusion, and already Microsoft has built an AI business that is larger than some of our biggest franchises,” Microsoft CEO Satya Nadella said in a statement. “We are pushing the frontier across our entire AI stack to drive new value for our customers and partners.”
