Amazon Stock Faces Capex Test After AWS Growth Hits 36.7%

Amazon delivered record quarterly revenue and its fastest AWS growth in years, yet the stock has lagged as investors focus on rising capital spending. The next key catalyst is the October 29 earnings report.

Amazon stock is being pulled in two directions. On one side are record operating results, including $200.6 billion in second-quarter revenue and 36.7% growth at Amazon Web Services. On the other is a sharp rise in capital spending that has pushed free cash flow into negative territory.

At a closing price of $246.15, Amazon was about 14.3% below its early-August 52-week high of $287.20. That retreat has come even as AWS posted its fastest expansion since 2021, highlighting how investors are weighing AI infrastructure spending against near-term cash returns.

The central question for markets is whether Amazon’s roughly $220 billion capital expenditure plan for 2026 will translate into durable earnings power or keep pressure on valuation until cash flow improves.

Key Facts

  • Amazon reported second-quarter revenue of $200.6 billion, up 19.6% year over year, and operating income of $27.5 billion.
  • AWS revenue rose 36.7% to $42.2 billion, with operating income of $16.6 billion and a 39.4% margin.
  • Trailing 12-month operating cash flow reached $161.4 billion, while trailing free cash flow was negative $7.6 billion.
  • Management lifted 2026 cash capital expenditure guidance to about $220 billion, mainly for AI and AWS capacity.
  • Amazon shares closed at $246.15, giving the company a market value of about $2.655 trillion.

Amazon Stock and AWS Growth

The tension around Amazon stock is not about weak demand. It is about timing, capital intensity, and how much patience investors are willing to show while the company builds out AI and cloud infrastructure. The operating backdrop remains strong. AWS has now posted five consecutive quarters of accelerating growth, and its backlog reached $496 billion, growing at a triple-digit pace.

That matters because AWS remains the main profit engine in Amazon’s valuation story. The cloud unit generated $16.6 billion in operating income in the quarter, nearly matching the profitability of the rest of the company on a far smaller revenue base. Advertising also continued to expand, growing 26%, while the North America and international retail businesses stayed profitable.

What has changed is investor tolerance for heavy spending. Second-quarter capital expenditures totaled $54.2 billion, and management’s updated outlook implies a sustained elevated pace. In a market increasingly sensitive to long-duration AI investments, Amazon is being judged not only on growth but on when that spending begins to convert into stronger free cash flow.

Amazon has some of the strongest cloud growth in large-cap tech, but the market wants proof that AI spending will translate into cash returns, not just backlog.

Why the free cash flow debate matters

Free cash flow has become a key battleground in the Amazon investment case. The company’s trailing free cash flow turned negative $7.6 billion after a large jump in property and equipment purchases. While operating cash flow remains substantial, the current spending cycle means reported cash generation does not yet reflect the earnings power bulls expect from AWS and AI services.

There is also a quality-of-earnings issue in the background. Net income in the second quarter was boosted by a $53.4 billion non-operating mark-to-market gain tied to Amazon’s stake in an AI company. That lifted headline earnings sharply, but investors are more focused on the core operating trend and on whether AWS growth above 35% can be sustained as new capacity comes online.

Implications for Investors

For investors, Amazon presents a classic trade-off between near-term cash pressure and long-term strategic advantage. On the bullish side, the company appears to have one of the strongest positions in cloud infrastructure, custom silicon, and enterprise AI services. AWS growth of 36.7%, a 39.4% operating margin, and a $496 billion backlog suggest demand remains strong enough to justify continued buildout.

The valuation argument is also part of the appeal. At roughly 19.2 times forward earnings based on the figures cited in the market debate, Amazon is seen by many analysts as cheaper than some other mega-cap technology peers. However, that multiple must be viewed carefully because consensus earnings have also been influenced by one-time gains rather than purely recurring operations.

The main watch-points are clear. First is the October 29 earnings report, where investors will look for revenue near the upper end of guidance and another strong AWS print. Second is operating income, especially whether margins remain resilient despite heavy infrastructure spending. Third is any update on backlog growth, AI customer commitments, and the path back to positive free cash flow. If Amazon can show that spending is converting into high-margin demand, the stock may regain leadership. If not, concerns about capex discipline could persist.

Amazon’s next few quarters are likely to determine whether the market sees its AI buildout as a temporary drag or a foundation for the next leg of earnings growth. For now, AWS momentum is strong, but investors still need evidence that scale and spending will translate into broader shareholder returns.
