US stock futures fell on Friday, led lower by a sharp decline in Amazon shares following earnings, as the broader technology selloff deepened.

Nasdaq 100 futures slid more than 1%, while S&P 500 and Dow futures were down 0.7% and 0.4%, respectively.

In extended trading, Amazon shares tumbled over 10% after the company said it expects to ramp up capital spending to about $200 billion this year, with much of the outlay directed toward AI projects and infrastructure.

The guidance disappointed investors already uneasy about the scale and sustainability of massive AI investments.

On Thursday, the S&P 500 and Nasdaq Composite fell 1.23% and 1.59%, respectively, with both benchmarks posting a third consecutive session of losses.

The Dow also dropped 1.2%.

Chipmakers came under pressure after Qualcomm sank 8.5% on a cautious outlook tied to softer memory demand and inventory headwinds.

Software stocks also extended declines amid growing concerns that AI could disrupt the sector.
