Amazon shares plunged after the tech giant reported mixed fourth-quarter earnings and issued an aggressive forecast for 2026 spending on AI.
Revenue for the October-to-December period edged Wall Street analysts’ consensus estimates, rising 14% from the year-ago quarter to $213.4. Earnings per share missed the mark by a penny, coming in at $1.95 on a diluted basis.
Amazon shares tumbled 4% in Thursday’s regular session and another 7% in after-hours trading as the earnings and other data points reached the marketplace. The company said it will spend $200 billion on AI in 2026, which is more than $55 billion more than analysts had been expecting.
The stocks of Amazon and many other large tech companies have come under pressure in recent days in the latest investor rethink of AI. With hundreds of billions of dollars a year collectively going toward data centers and other resources, some see a bubble set to burst.
In the company’s quarterly letter to shareholders, CEO Andy Jassy assured them that the long-term return on the immense capital outlay will be “strong.” The level of spending was set in light of “strong demand for our existing offerings and seminal opportunities like AI, chips, robotics, and low earth orbit satellites,” he said.
The holiday quarter included the most-viewed season to date of Thursday Night Football on Prime Video, with 15.33 million average viewers for each of the regular season’s 15 games. Prime Video also started streaming NBA games last October, kicking off an 11-year deal. Black Friday has also become a football window for showcasing advertising both on Prime and across the company’s home page and e-commerce operation.
Prime’s strides during the quarter included another jump in ad revenue, which climbed 22% from a year ago to $21.3 billion, the latest 20%-plus quarterly increase in the category.
