Amazon, Microsoft, Alphabet and Meta spent about $202 billion on property and equipment from July through September 2026, more than twice the amount a year earlier, according to company filings compiled in the source material. Their funding mix now includes operating cash, debt, leases, partnerships and stock sales, while the scale of future obligations raises questions about who bears the cost if AI revenues lag.
Amazon, Microsoft, Alphabet and Meta spent about $202 billion on property and equipment from July through September 2026, more than double their spending in the same quarter a year earlier, according to a calculation based on their filings. As data center and AI infrastructure costs rise, the companies are drawing on debt, leases, partnerships and stock sales as well as operating cash, raising questions about how much risk may ultimately reach investors, landlords and electricity customers.
The four companies’ combined property and equipment spending was about $202 billion, compared with about $97 billion a year earlier. The source’s figures, drawn from company cash flow statements, include more than AI infrastructure: Amazon also invests in warehouses. Amazon reported $77.3 billion in property and equipment purchases for the quarter, up from $35.1 billion a year earlier, and said the increase primarily reflected AI investment. It expects about $220 billion in cash capital spending for 2026.
Alphabet reported $51.4 billion in spending, up from $24 billion a year earlier. Its 2026 forecast remained at $195 billion to $205 billion, and it forecast a significant increase in 2027. Microsoft spent $39.4 billion, while Meta spent $33.9 billion. The source’s comparison of spending with operating cash indicates that three of the four spent more on property and equipment than their businesses generated in cash during the quarter; Microsoft generated $58 billion in operating cash against $39.4 billion in spending.
Borrowing and equity are also part of the funding mix. The source’s tally of company filings says Amazon, Alphabet and Meta raised about $225 billion in long-term debt during the first nine months of 2026. Microsoft issued $25 billion in bonds this week, including debt that matures in 2066. Meta said it plans to fund AI investment through a mix of operating cash flow, investment-grade debt, strategic partnerships and equity capital.

From Cash to Power Bills: Who Covers the Cost of AI Data Centers?
Four technology giants spent about $202 billion on property and equipment in one quarter. Cash is still in the mix, but so are debt, leases, partnerships and equity—and the commitments can outlast the servers.
The central question
$1.02T
Estimated future payments on signed leases not yet started as of September 30, mostly tied to data centers.
Author’s combined estimate
Calculated from four quarterly filings; not a single company-reported total.
Four companies. One quarter. $202 billion.
Company filings put combined property and equipment purchases at more than twice the level a year earlier. These totals cover broader investment, not AI alone.
Amazon
$77.3B↑ from $35.1B a year earlier. Increase primarily reflected AI investment; warehouses are also included.
Alphabet

Cash remains central. It is no longer alone.
The funding mix has widened as infrastructure needs rise. The figures do not mean every dollar raised is dedicated to AI.
Debt extends the funding runway
Amazon, Alphabet and Meta raised about $225 billion in long-term debt during the first nine months of 2026, according to the source’s tally of filings. Microsoft issued $25 billion in bonds, including debt maturing in 2066.
More ways to share capital needs
Meta described a balanced mix of operating cash flow, investment-grade debt, strategic partnerships and equity capital. Leases and long-term power contracts also support the build-out.

The financing creates connected obligations across a long infrastructure chain. Filings show exposure exists; they do not show that costs have shifted to any particular group.
Technology firms
Fund construction, equipment and power through cash and multiple financing sources.
Lenders & investors
Provide debt and equity, with returns tied to companies’ ability to sustain commitments.
Building owners
Lease data center space under agreements that can last well beyond server lifetimes.
Electricity customers
May be exposed to power costs; the source does not quantify any transfer or timing.
$1.02T
Estimated future payments under signed leases that had not started by September 30, mostly for data centers. This is the source author’s sum of four filings; no company-by-company breakdown is provided.
If AI demand or revenue grows more slowly than expected, lease, power and debt obligations still come due.
Revenue has to meet long commitments.
The available figures document investment and obligations. They do not establish how much future AI revenue will cover costs—or whether the market is in a bubble.
How much did the four spend?
About $202 billion on property and equipment in July–September 2026. The total includes investments beyond AI.
Who is paying for the build-out?
Companies use operating cash, debt, leases, partnerships and equity, alongside long-term power contracts. Cost shifts to outside parties are not quantified.
What does $1.02 trillion represent?
An estimated combined total of future payments on signed leases not yet started as of September 30, based on four filings; most are described as data center related.
Does spending prove there is a bubble?
No. The figures show the scale of investment and obligations, but not whether future revenue will meet costs or whether the market is a bubble.
Next indicators: future quarterly filings on capital spending, debt issuance and lease commitments; Amazon’s 2026 spend expectation is about $220 billion, and Alphabet’s is $195–$205 billion.
Who Carries the Infrastructure Cost
The financing choices matter because the build-out creates obligations that can last longer than the equipment they support. The source estimates the four companies had about $1.02 trillion in future payments under signed leases that had not yet started as of September 30, mostly for data centers. That is a calculation from their quarterly filings, not a single company-reported total.
Servers are typically written off over five to six years, while data center leases and power contracts can last 15 to 20 years, and some bonds run for 40 years. If demand for AI services or revenue grows more slowly than expected, companies still have to meet these longer commitments. The strain could be felt by technology firms, their lenders and investors, companies that own data center buildings, and customers exposed to electricity costs. The filings and figures do not establish that costs have been passed on to any particular group.

From Profits to Multiple Funding Sources
For years, the largest technology companies could fund data centers from cash generated by advertising, software and online commerce. The source describes 2026 as a shift toward using several financing methods at once: cash, debt, leases, partnerships and new shares, alongside long-term power contracts. That does not mean every dollar raised is dedicated to AI; the reported capital spending covers broader property and equipment, and the source notes Amazon’s warehouse investments.
Companies’ results and filings provide the basis for the spending and debt figures, while some totals in the source are the author’s calculations combining those reports. The spending comparison covers July through September 2026. Microsoft’s quarter is its fiscal first quarter of 2027, covering the same calendar months. The source also points to newer GPU cloud providers such as CoreWeave, whose senior notes carry stated interest rates of 8.5% to 9.75%, as a more financially exposed part of the infrastructure market. Those rates alone do not establish the company’s overall risk or future ability to pay.
“through a balanced mix of operating cash flow, investment-grade debt, strategic partnerships, and equity capital.”
— Meta, in a statement about funding AI investment on October 26, 2026
Revenue and Long-Term Commitments
The filings show reported spending, debt and lease obligations, but do not establish how much future AI revenue will cover those costs. It is also unclear how much of the combined property and equipment spending is directly tied to AI, since the figures include other investments, and the source explicitly notes Amazon’s warehouse construction.
The estimated $1.02 trillion in future lease payments is the source author’s sum of four filings; the material does not provide a company-by-company breakdown. It does not quantify how much of the financing risk has shifted to building owners, lenders, shareholders or power customers. The timing and scale of any resulting cost increases are also not established.
Upcoming Spending and Financing
The next indicators are the companies’ future quarterly filings, which can show whether capital spending, debt issuance and lease commitments continue to rise. Amazon’s stated 2026 spending expectation is about $220 billion, while Alphabet has held its 2026 forecast at $195 billion to $205 billion and expects a significant increase in 2027.
Investors and customers will also be watching whether AI services generate enough revenue to support the infrastructure and long-term contracts. The source material does not identify a specific upcoming decision or date that will settle that question.
Key Questions
How much did the four companies spend in the third quarter of 2026?
About $202 billion on property and equipment from July through September, according to a total calculated from company filings. The figure is not limited to AI spending.
Who is paying for the data center build-out?
The companies are using a mix of operating cash, borrowing, leases, partnerships and equity. Long-term power contracts also support data center operations. The source does not quantify how much cost has shifted to outside parties.
What does the $1.02 trillion lease figure represent?
It is the source author’s combined estimate of future payments under signed leases that had not started as of September 30, 2026, based on four company filings. Most of those leases are described as data center related.
Does the spending prove that AI data centers are a bubble?
No. The spending and financing figures show the scale of investment and obligations, but they do not establish whether expected AI revenue will meet costs or whether the market is in a bubble.
