Amazon’s cash engine is getting stronger and spending even faster
Amazon’s AI expansion could bring annual capital spending within striking distance of half a trillion dollars. The company is already demonstrating how stronger business performance can coexist with much heavier cash consumption.
JPMorgan analyst Doug Anmuth projects $395 billion in capital expenditures for 2027 and $476 billion for 2028. Those are analyst estimates. Amazon’s own guidance remains approximately $220 billion for 2026, with management expecting spending to increase meaningfully next year.
The latest cash-flow reconciliation shows how quickly the investment bill is expanding:
| Trailing 12 months through September | 2025 | 2026 |
|---|---|---|
| Operating cash flow | $130.7 billion | $168.3 billion |
| Net property and equipment purchases | $115.9 billion | $210.7 billion |
| Free cash flow | $14.8 billion | −$42.4 billion |
Amazon generated roughly $37.6 billion more operating cash, but net property and equipment purchases increased by approximately $94.8 billion. Its cash engine improved substantially while its infrastructure bill grew much faster.
AWS demand gives Amazon a reason to keep building
The spending has a growing business behind it. AWS revenue reached $46 billion, rising approximately 39%, while segment operating income increased to $17.8 billion. AWS supplied nearly two-thirds of Amazon’s total operating profit during the quarter.
Andy Jassy projects AWS revenue growth above 40% in both 2027 and 2028. Supporting that outlook, Amazon disclosed approximately $578 billion in remaining contractual commitments, primarily associated with AWS.
One detail deserves particular attention: those long-term contracts have a weighted-average remaining life of 6.1 years. Revenue recognition depends on customer usage and Amazon delivering the contracted services. The backlog provides visibility, but it does not represent cash immediately available to finance construction.
Amazon must install capacity before collecting much of the revenue that justifies it. Strong demand can therefore increase the immediate funding requirement as the company races to serve customers.

The return on each new dollar becomes the test
A $476 billion spending forecast raises the stakes around how quickly infrastructure starts earning its keep.
Capital spending buys assets expected to generate revenue over several years. Cash leaves upfront, while depreciation spreads much of the accounting expense across their useful lives. Investors consequently need to examine both operating earnings and the cash required to sustain expansion.
Amazon’s filing already shows AWS depreciation and amortization rising to $9.2 billion in the quarter from $5.6 billion a year earlier. The existing build-out is reaching the income statement even as further investment accelerates.
Successful expansion requires customers to use the new capacity at prices that cover equipment, power, maintenance and financing while leaving an attractive return.
Amazon has supplied evidence of demand and growing operating cash generation. The next proof is whether each wave of capacity produces enough additional cash to support the wave behind it. At nearly half a trillion dollars annually, the time between buying equipment and earning back its cost becomes a central part of the investment case.
