Amazon.com Inc. reported third-quarter results that exceeded Wall Street expectations, fueled by faster-than-anticipated growth in its cloud computing division, Amazon Web Services.

The e-commerce giant’s earnings, released Thursday after markets closed, outperformed on both revenue and profit. The results came a day after Microsoft Corp. and Alphabet Inc. unveiled their own quarterly numbers, with both tech rivals pledging increased spending on AI-related data centers.

“We’ll continue to invest aggressively in capacity because we’re seeing strong demand,” Chief Executive Officer Andy Jassy told analysts on a conference call.

Amazon shares jumped more than 13% in extended trading following the report.
