The tech giant tapped the U.S. investment-grade debt market for the first time since 2017, drawing up to $115 billion in investor demand.

In short
- Microsoft announced the pricing of a $25 billion senior unsecured note offering divided into ten floating- and fixed-rate tranches maturing between 2028 and 2066.
- Order books reached as high as $115 billion, demonstrating strong investor demand for Microsoft's rare AAA-rated corporate debt.
- Proceeds are designated for general corporate purposes, including capital expenditures as Microsoft targets $170 billion in capital spending for 2026.
- Unlike hyperscaler peers Alphabet, Meta, and Amazon, which recently posted negative free cash flow, Microsoft maintained positive free cash flow in its latest quarter.
Microsoft Corp. priced a $25 billion offering of senior unsecured notes on October 29, 2026, marking its first transaction in the U.S. investment-grade bond market since 2017. The massive debt sale arrives as the company targets $170 billion in capital expenditures in 2026 to support its expanding artificial intelligence and cloud computing infrastructure, according to reporting by Superpower Daily.
According to an official release from Microsoft, the company plans to use the net proceeds for general corporate purposes. These include working capital, capital expenditures, stock repurchases, acquisitions, and the repayment of existing debt. The transaction is scheduled to close on November 4, 2026.

Structure of the Ten-Tranche Debt Offering
The bond offering is structured across ten tranches, combining floating-rate debt with fixed-rate notes carrying maturities that extend from two to 40 years, as detailed in Microsoft's debt announcement.
The two floating-rate tranches total $2.00 billion:
- $1.00 billion due November 3, 2028, paying Compounded SOFR plus a spread
- $1.00 billion due November 3, 2029, paying Compounded SOFR plus a spread
The remaining eight tranches consist of fixed-rate paper across maturities running through 2066:
- $2.00 billion at 4.85 percent due November 3, 2028
- $3.25 billion at 5.00 percent due November 3, 2029
- $3.25 billion at 5.20 percent due November 3, 2031
- $2.50 billion at 5.35 percent due November 3, 2033
- $4.00 billion at 5.55 percent due November 3, 2036
- $2.00 billion at 6.15 percent due November 3, 2046
- $4.00 billion at 6.25 percent due November 3, 2056
- $2.00 billion at 6.35 percent due November 3, 2066
J.P. Morgan Securities, UBS Securities, and Wells Fargo Securities acted as joint lead book-running managers alongside eight other primary underwriters, including Barclays, Goldman Sachs, and Morgan Stanley. As noted by Quartz, the notes will be senior unsecured obligations, ranking equally with existing unsecured debt, and will not be listed on any securities exchange. Microsoft reported total outstanding debt of $35.481 billion as of September 30, 2026.
Surging Investor Demand and Pricing Spreads
Investor interest in the offering proved intense. Bids peaked at $115 billion, according to people familiar with the matter cited by Business Standard, representing an oversubscription rate of roughly 4.6 times the issued amount.
Strong demand enabled underwriters to reduce the risk premiums demanded by debt investors. On the 40-year tranche maturing in 2066, pricing tightened by as much as 0.30 percentage points during marketing, settling at a spread of 1.05 percentage points over benchmark Treasuries. In comparison, Alphabet sold 40-year debt on August 6 at a wider spread of roughly 1.33 percentage points over Treasuries, reflecting Microsoft's premier credit standing.
Alongside healthcare giant Johnson & Johnson, Microsoft is one of only two publicly traded U.S. corporations to hold top AAA credit ratings from both Moody’s Ratings and S&P Global Ratings, as reported by Business Standard. Analysts at CreditSights calculated that the $25 billion issuance will elevate the company's gross lease-adjusted leverage only slightly to 0.7 times.

Big Tech Debt and Cash Flow Divergence
The transaction highlights differing financial trajectories across the technology sector. As tracked by Livemint, global hyperscalers and data center operators have traditionally relied on substantial internal cash flow to fund hardware and facilities. However, with massive computing demands, several major firms have turned to debt or equity.
Microsoft stands apart from several hyperscaler rivals because it continues to generate positive free cash flow. In fiscal first-quarter earnings reported on October 28, Microsoft posted 48 percent growth in Azure revenue and affirmed that it expects free cash flow to stay positive throughout its fiscal year ending June 2027. By comparison, Alphabet recently logged its second consecutive quarter of negative free cash flow, while Meta and Amazon also reported negative free cash flow, according to Livemint.
Other tech firms have pursued different capital strategies. Oracle disclosed plans to raise $10 billion in debt while committing to limit gross debt growth through fiscal 2030, and Meta turned to public equity markets to raise $25 billion. Meanwhile, specialized infrastructure operator CoreWeave saw its 2032 debt trade at elevated yields near 14.2 percent following broader pressure on high-yield debt, as reported by Morningstar.
Financing Infrastructure for the Next Phase of Growth
On Microsoft's quarterly earnings call, Chief Financial Officer Amy Hood addressed the company's funding philosophy, stating that management intends to pursue additional external capital "when we believe it is attractive to do so." Hood emphasized the value of maintaining financial flexibility while drawing on existing debt capacity.
Market participants noted that the success of the bond sale reflects a widening tiering among technology borrowers. Byron Anderson, head of fixed income at Laffer Tengler Investments, told Morningstar that markets are splitting into "haves and have-nots" based on balance sheet strength.
Year-to-date in 2026, global investment-grade bond sales by hyperscalers and data center developers have exceeded $313 billion, nearly triple the volume recorded across all of 2025, according to Bloomberg data cited by Business Standard. Microsoft's successful multi-decade financing suggests that while credit markets remain selective, top-rated tech firms can still command deep liquidity at low risk premiums.
