Amazon’s Extreme AI Spending Sends Stock to Worst Month in Years

Amazon.com Inc. may be a leader in the artificial intelligence race, but investors are increasingly unwilling to pay up for the cost of maintaining that position.

Shares of the e-commerce and cloud computing giant plunged 12% in February, their worst month since December 2022, as Wall Street takes an increasingly jaundiced view of the company’s aggressive AI spending plans. Not only are the capital expenditures eating into Amazon’s free cash flow, but market pros are growing impatient about when they’ll pay off in dramatic fashion.

The stock also was the worst performer of the so-called Magnificent Seven technology behemoths last month and among the 40 weakest companies in the S&P 500. And that’s coming off a tepid 5.2% gain in 2025, which was the weakest return in the Mag Seven as well.

“Amazon is starting to look like a cautionary tale, because its investments are so high but the returns are among the lowest in Big Tech,” said Adam Rich, who helps oversee more than $15 billion in assets as deputy chief investment officer and portfolio manager at Vaughan Nelson Investment Management. “The growth we’re seeing just isn’t enough to justify the higher capex.”

Amazon was down around 2% on Monday as part of a broader selloff in equity markets following military strikes across the Middle East.
