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.

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.

The massive sum will go towards building out datacenters for training AI models, as well as deploying and improving global AI and cloud-based applications.
