AI infrastructure spending in 2026 is running at a pace with no precedent in corporate history. In the March 2026 quarter alone, Microsoft (MSFT), Alphabet (GOOGL), Meta Platforms (META) and Amazon (AMZN) together reported about $130.6 billion of capital expenditures, and Meta raised its full-year 2026 capital spending outlook to $125 billion to $145 billion [4]. The largest single collector of that money is Nvidia (NVDA), whose data center revenue reached a record $75.2 billion in the quarter ended April 26, 2026, up 92% from a year earlier, as of May 20, 2026 [1]. This note walks through who is spending, who is collecting, and what the numbers say about returns.
How much is AI infrastructure spending in 2026?
The four largest cloud and platform companies disclose capital spending every quarter, and the March 2026 quarter set a new high for each of them. Microsoft reported $30.9 billion of additions to property and equipment for the quarter ended March 31, 2026 [2]. Alphabet reported $35.7 billion of purchases of property and equipment in the same period [3]. Meta reported $19.8 billion of capital expenditures including finance lease principal payments [4]. Amazon reported $44.2 billion of capital expenditures in the first quarter and $151.0 billion over the trailing twelve months [5].
Adding the four quarterly figures gives about $130.6 billion for a single quarter, an annualized run rate above $520 billion before any further increases. Meta is the only one of the four that publishes a formal full-year capital expenditure range, and it moved that range up by $10 billion at both ends, from $115 billion to $135 billion to $125 billion to $145 billion, citing higher component pricing and, to a lesser extent, additional data center costs [4]. Higher component pricing is a direct signal that suppliers, not buyers, hold pricing power in this cycle.
| Company | Quarter ended | Capital expenditures | Revenue growth |
|---|---|---|---|
| Microsoft (MSFT) | March 31, 2026 | $30.9 billion | 18% [2] |
| Alphabet (GOOGL) | March 31, 2026 | $35.7 billion | 22% [3] |
| Meta Platforms (META) | March 31, 2026 | $19.8 billion | 33% [4] |
| Amazon (AMZN) | March 31, 2026 | $44.2 billion | 17% [5] |
Who is collecting the money?
Nvidia: the primary beneficiary of data center capital budgets
Nvidia's results for the first quarter of fiscal 2027, released on May 20, 2026, show where much of the capital goes. Total revenue was $81.6 billion, up 85% from a year earlier, and data center revenue was $75.2 billion, up 21% from the prior quarter and 92% from a year earlier [1]. GAAP gross margin was 74.9% and net income was $58.3 billion [1]. For the second quarter of fiscal 2027, Nvidia guided to revenue of $91.0 billion, plus or minus 2% [1]. Nvidia also changed its reporting structure to two segments, Data Center and Edge Computing, with Edge Computing (which now includes gaming) at $6.4 billion [1].
DataPorium's business segment data puts the shift in context: in fiscal 2026, Nvidia's Compute and Networking segment generated $193.5 billion of revenue against $22.5 billion for Graphics, and the United States accounted for $149.6 billion of company revenue [6]. Investors can track this and other segment breakdowns on DataPorium's stock market pages.
The cloud platforms: spending to sell capacity
The spenders are also collectors, because most of the capacity is rented out. Microsoft's Intelligent Cloud revenue was $34.7 billion, up 30%, with Azure and other cloud services up 40%, and the company said its AI business reached an annual revenue run rate of $37 billion, up 123% year over year [2]. Google Cloud revenue was $20.0 billion, up 63% [3]. Amazon Web Services revenue was $37.6 billion, up 28%, with AWS operating income of $14.2 billion [5]. Those growth rates are the demand signal that justifies the capital budgets, at least for now.
Are the returns on AI infrastructure spending holding up?
The profit numbers say yes so far. Microsoft's net income rose 23% to $31.8 billion [2]. Alphabet's operating income rose 30% to $39.7 billion, with operating margin expanding two percentage points to 36.1% [3]. Meta's net income rose 61% to $26.8 billion on revenue of $56.3 billion, up 33% [4]. Amazon's operating income was $23.9 billion, up from $18.4 billion a year earlier [5]. Every one of the big four is growing profits while spending more, which is the opposite of what a bubble usually looks like at this stage.
The caution is in cash flow and depreciation. Amazon's trailing twelve month capital spending of $151.0 billion is close to its trailing revenue growth in dollar terms, and Meta guided total 2026 expenses to $162 billion to $169 billion [4][5]. Depreciation on servers bought in 2025 and 2026 will hit income statements for years. If AI service revenue growth slows before that depreciation is absorbed, margins would compress. That is the main risk investors may want to monitor.
What the market is pricing
DataPorium's sector data shows the technology sector on NASDAQ trading at an average price to earnings ratio of about 50.0 as of July 6, 2026, compared with about 20.8 for financial services and 16.9 for energy [6]. That premium reflects expectations that the capital spending will keep producing revenue growth in the 20% to 60% range seen in the cloud units above. The sector was roughly flat on July 6, down 0.08% on average [6].
- Spenders: Microsoft, Alphabet, Meta and Amazon, about $130.6 billion of capital expenditures in the March 2026 quarter combined [2][3][4][5].
- Collectors: Nvidia, with $75.2 billion of data center revenue in its April 2026 quarter [1].
- Demand proof: Azure up 40%, Google Cloud up 63%, AWS up 28% [2][3][5].
- Risk: rising component prices and future depreciation, as Meta's raised expense outlook shows [4].
The AI build-out is being funded from record profits rather than debt, which makes it more durable than past capital spending booms, but the return on that capital will be decided by whether cloud AI revenue keeps growing faster than depreciation.
From a market-oriented view, this is private capital taking private risk. No public subsidy is driving the $130 billion quarterly figure. That is healthy: if the returns fail, shareholders of the four companies bear the cost, and if the returns succeed, the productivity gains spread across the economy. The counterpoint is concentration. A handful of buyers and one dominant chip supplier create dependence on a few balance sheets, and any pause by one large buyer would ripple through the entire supply chain.
Key takeaways
- Microsoft, Alphabet, Meta and Amazon reported about $130.6 billion of combined capital expenditures in the March 2026 quarter [2][3][4][5].

- Cloud revenue growth (Azure 40%, Google Cloud 63%, AWS 28%) is the demand evidence behind the spending [2][3][5].
- NASDAQ technology stocks traded at an average P/E near 50 as of July 6, 2026, according to DataPorium sector data [6].
Frequently asked questions
How much will big tech spend on AI in 2026?
Only Meta publishes a formal full-year range, $125 billion to $145 billion for 2026 [4]. The four largest spenders together reported about $130.6 billion of capital expenditures in the March 2026 quarter alone [2][3][4][5].
Which company makes the most money from AI infrastructure?
Nvidia reported $75.2 billion of data center revenue and $58.3 billion of net income in its quarter ended April 26, 2026, with a 74.9% GAAP gross margin [1].
Is AI spending paying off for cloud providers?
Growth rates suggest it is so far: Azure grew 40%, Google Cloud grew 63% and AWS grew 28% in the March 2026 quarter, and all four parent companies grew profits [2][3][5].
What is the biggest risk to AI infrastructure investment?
Depreciation on hundreds of billions of dollars of servers will weigh on earnings for years, so a slowdown in AI service revenue before that cost is absorbed would compress margins.
