More than half of the investment has been earmarked for infrastructure in the U.S.. Microsoft President Brad Smith frames AI investment as key to economic growth.

Microsoft is set to double down on its generative artificial intelligence efforts in 2025 following the company's Vice Chair and President, Brad Smith's recent announcement of the tech giant's plans to invest up to $80 billion in building data centers.

Microsoft is one of the biggest spenders, followed closely by Google and AWS, Bloomberg Intelligence said. Its estimate of Microsoft’s capital spending on AI, at $62.4 billion for calendar 2025, is lower than Smith’s claim that the company will invest $80 billion in the fiscal year to June 30, 2025.
