Microsoft plans to raise about $25 billion through a U.S. bond offering for AI-related capital expenditures
On October 29, 2026, people familiar with the matter told Reuters and Bloomberg that Microsoft plans to raise about $25 billion through its first U.S. investment-grade bond offering in more than nine years. The bond offering is proposed to be divided into as many as 10 maturity tranches, with maturity dates ranging from 2 years to 40 years, and the final size may be adjusted based on demand. Wells Fargo, JPMorgan Chase and UBS are the underwriters.
Microsoft confirmed the bond offering in a regulatory filing, but did not disclose the specific size. CFO Amy Hood said on the prior day’s earnings call that the company would seek additional sources of financing when it considered them attractive, in order to preserve cash flow and financial flexibility. Microsoft’s capital expenditures and finance leases last quarter were about $45.2 billion, and Azure revenue increased 48% year over year to $33.2 billion.
The offering is at the planning stage and has not yet been priced or completed. Bloomberg later reported that the offering attracted more than four times demand. Microsoft’s last U.S. investment-grade bond offering was $17 billion in 2017.

ABAB AI Insight
This bond offering by Microsoft is an action to seek debt financing amid rising capital expenditures on AI infrastructure. The company’s capital expenditures last quarter were about $45.2 billion, and Azure demand continues to exceed current capacity that can be brought online. By issuing long-dated bonds, the company can spread part of its financing costs over the coming decades while keeping cash available for other uses.
On the capital path, large technology companies have increased their use of the debt market over the past year to support investments in data centers and related equipment. Microsoft has an AAA rating, which gives it relatively low financing costs. The final size of the offering depends on investor demand, and current reports show demand exceeded four times, indicating the market’s acceptance of the company’s credit profile.
Unlike relying entirely on internal cash flow, this offering gives the company an additional funding option. The actual use of proceeds will depend on subsequent capital expenditure progress and project delivery. Metrics to watch are the final pricing and size of the bonds, as well as whether Microsoft later raises its capital expenditure guidance.
