Microsoft is set to raise $25 billion in new debt to bolster its infrastructure and meet the surging demand for AI computing power. The tech giant’s strong AAA credit rating allows it to access favorable debt markets to fund its ambitious capital expenditures for 2026.
This financial move highlights Microsoft’s commitment to expanding its AI capabilities, contrasting with some competitors who have also recently sought debt financing for similar infrastructure projects amidst a tightening economic environment.
Microsoft Secures $25 Billion in Debt to Fuel AI Infrastructure Boom
October 29, 2026 - Microsoft announced on Thursday its intention to raise $25 billion through bond offerings, leveraging its strong credit rating to finance a significant expansion of its infrastructure. This move comes as the tech giant prepares to meet escalating demand for artificial intelligence computing power from major clients like OpenAI and Anthropic, as well as other customers.

The company, which boasts a top-tier AAA credit rating from S&P, is targeting $170 billion in capital expenditures for 2026. "Microsoft 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 company stated in a press release. The debt offerings are expected to close on November 4.
This strategic debt financing by Microsoft follows similar moves by industry giants like Amazon and Alphabet, who have also tapped the bond markets to support their extensive infrastructure projects this year. Even AI-focused cloud provider CoreWeave has utilized debt financing to expand its data center capabilities. However, investors are becoming increasingly cautious about companies with significant debt loads amid rising interest rates aimed at combating inflation.
Microsoft's finance chief, Amy Hood, indicated on the company's earnings call that Microsoft would supplement its cash flow generation with additional funding sources when market conditions are favorable. "We're fortunate to have access in the debt markets, given where our ratings are, and we haven't yet tapped that," Hood remarked, also noting the company's use of leasing as a financing vehicle.
In contrast to some competitors, Microsoft reported positive free cash flow on Wednesday, a distinction from Alphabet, which experienced negative free cash flow for the second consecutive quarter. Last week, Meta also reported negative free cash flow, and Amazon followed suit with its own negative free cash flow announcement on Thursday.
In related news, Oracle recently unveiled plans to raise $10 billion in new debt, projecting a return to positive free cash flow in the latter half of its 2028 fiscal year.
