Amazon Q3 2026 Earnings: AWS Booms, Free Cash Flow Sinks

Amazon Is Borrowing Its Way Into the AI Race

Amazon’s best cloud quarter in five years came with a $42.4 billion free cash flow hole and a debt pile that has more than doubled since December. The market noticed.

AWS revenue grew 39.3% to $46 billion, its fastest growth in almost five years, and now drives about 63% of Amazon’s operating profit.
Amazon’s trailing free cash flow fell to minus $42.4 billion, down from minus $7.6 billion just three months earlier.
Long-term debt rose from $65.6 billion to $173.1 billion in nine months as capex heads toward $220 billion this year.
Microsoft spent heavily too but stayed cash positive, adding $18.6 billion in free cash flow over the same quarter.

Amazon has just posted its best cloud quarter in almost five years. AWS revenue jumped 39.3% to $46 billion, helping push the company's operating margin to a record 13.9%, and Andy Jassy, Amazon's president and CEO, told analysts that AWS would grow by more than 40% in both 2027 and 2028.

But investors heard all of that and sold anyway, knocking more than 6% off the stock in after hours trading.

That isn't a contradiction so much as a verdict. For two years, the market treated Amazon's AI spending as a story about the future. On October 29, it started reading it as a story about the balance sheet, because the numbers beneath the AWS headline show a company that's no longer paying for its future out of what it earns today. It's borrowing to build it.

What Amazon reported in Q3 2026

The headline numbers were good, which is what makes the selloff interesting.

Revenue rose 12% to $201.9 billion, just shy of the roughly $202.1 billion analysts expected, and earnings per share of $1.89 came in a few cents below the $1.96 estimate. Net income dipped to $20.7 billion from $21.2 billion, but that comparison flatters last year, which included a large gain on Amazon's stake in Anthropic. Operating income is the cleaner measure, and it rose 61% to $28.1 billion.

Most of that came from AWS, whose operating income climbed to $17.8 billion from $11.4 billion a year earlier. In other words, a division that brings in less than a quarter of Amazon's revenue now produces about 63% of its operating profit, which explains why Jassy sounded so confident:

"Our AWS investment in functionality and infrastructure is working, with over 39% year-over-year revenue growth in Q3 ($184 billion revenue run rate) and projected revenue growth rates of over 40% both in 2027 and in 2028."

Had the story ended there, the stock would probably have gone up. It didn't, and the reason sits in the cash flow statement.
