Over half of the investment is reserved for infrastructure. Microsoft President Brad Smith frames AI investment as key to economic growth.

The tech giant has pledged that all data centers serving its cloud by this year will have power purchase agreements for 100 percent low-carbon energy.

Many companies and brands have begun shifting to more sustainable practices in recent years. Microsoft has long been leading the charge, pledging to be carbon negative by 2030. And it's now added another tactic in the fight for sustainability: building data centers made of wood and other low-carbon materials.

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 planning to invest about $80 billion in fiscal 2025 on developing data centers to train artificial intelligence (AI) models and deploy AI and cloud-based applications, the company said in a blog post on Friday.

As Microsoft pledges $80 billion on data center spending this year, Michael Stewart of M12 - Microsoft's venture arm - says it will be the quality of AI that will matter in the long run. He joins Caroline Hyde on "Bloomberg Technology" to discuss.

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.

With those whopping returns who could argue with the premis... oh wait The AI datacenter spending splurge looks likely to continue in 2025, with Microsoft alone saying it will invest $80 billion this year on building out infrastructure to train and deploy AI models.
