Microsoft is seeking to raise at least $25 billion through a US bond sale, according to multiple reports. The proposed offering would be Microsoft’s first US investment-grade bond sale in several years, with Bloomberg reporting it would be split into multiple tranches and include maturities spanning roughly two to 40 years. The final size would depend on market conditions, the reports say.

The coverage places the deal in the broader context of corporate borrowing and investment. One report frames it as part of a wider borrowing push by technology companies to fund artificial intelligence-related spending. Another notes the sale would mark a return to US high-grade debt issuance after a long gap. Across outlets, the core details—size target, US location, and the “first since” timing—are consistent, while emphasis varies between deal mechanics and the AI spending context.
