Microsoft on Thursday announced plans to raise $25 billion in bonds, leveraging its top-tier AAA credit rating, to support its expanding infrastructure as it works to meet demand from artificial intelligence labs Anthropic and OpenAI.
The offerings are expected to close on Nov. 4, the company said. In a statement, Microsoft said it intends to use the net proceeds from the offering for general corporate purposes, which may include, among other things, funding for working capital, capital expenditures, repurchases of capital stock, acquisitions, and repayment of existing debt.
The move is part of Microsoft's push into AI infrastructure, with management targeting $170 billion in capital expenditures for 2026. Finance chief Amy Hood, speaking on the company's earnings call on Wednesday, said the company is fortunate to have access to debt markets given its credit rating, and noted that Microsoft also uses leasing as a financing vehicle. "There's a form of financing called leasing, and we've been using that one as a vehicle," Hood said.
Amazon and Alphabet have engaged the bond market to support infrastructure projects this year, and AI-focused cloud provider CoreWeave has also relied on debt to broaden its data center footprint. Microsoft reported positive free cash flow on Wednesday, differentiating itself from Alphabet, whose cash flow was negative for the second consecutive quarter. Last week Meta said it had negative free cash flow, and on Thursday Amazon reported negative free cash flow. Separately, Oracle unveiled plans to raise $10 billion in new debt and said it anticipates a return to positive free cash flow in the second half of its fiscal 2028 year.
Analysis
Why This Matters
- Microsoft's massive bond issuance signals the scale of capital required for AI infrastructure, with implications for the broader tech industry and investors.
- The move highlights how even cash-rich companies are leveraging debt to fund AI buildout, potentially influencing other firms' financing strategies.
- The growing reliance on debt markets for AI investment could affect interest rates and credit availability for other sectors.
Background
Microsoft is racing to expand its data center capacity to meet surging demand from AI companies, particularly its partner OpenAI and rival Anthropic, which both rely on Microsoft's cloud infrastructure. The company has committed to $170 billion in capital expenditures in 2026, a dramatic increase from prior years. The bond offering is one of several financing tools Microsoft is using, alongside leasing and internal cash flow, to fund this expansion.
What to Watch
- The Nov. 4 closing date for the bond offering: how quickly the bonds are taken up and at what yields.
- Whether Microsoft's competitors also turn to debt markets for AI investment, and how their credit ratings affect terms.
- The trajectory of interest rates: rising rates could make future debt more expensive, impacting long-term capital plans.
