Microsoft Seeks at Least US$25 Billion in First US Bond Sale Since 2017
A possible 10-part sale would fund general corporate needs, including capital spending, as investors weigh borrowing for the AI buildout.
Microsoft is seeking at least US$25 billion in its first US investment-grade bond sale in more than nine years, putting its borrowing plans under scrutiny as technology companies raise funds for the artificial intelligence buildout. The sale will also show how much demand investors have for long-term debt from a highly rated company while questions grow about the scale and durability of AI spending.
The target is not final. People familiar with the matter said the size could change with demand, and the company is marketing the debt in as many as 10 tranches, with maturities ranging from two to 40 years. That range would let buyers choose between shorter repayment periods and longer exposure to Microsoft’s credit.
For the longest maturity, a note due in 2066, initial price talk indicates a premium of as much as 1.35 percentage points above US Treasuries. That spread is an early guide to the additional yield buyers may seek for holding the corporate note instead of US government debt. Final pricing can differ from initial discussions as demand and terms take shape.
Borrowing returns after a long gap
Microsoft last issued high-grade debt in 2017, raising US$17 billion, according to data compiled by Bloomberg. The proposed sale would therefore mark a return to the US bond market after a substantial pause, and its minimum target is larger than that earlier deal. The comparison shows the scale of the current financing plan, though the article does not specify how much Microsoft ultimately expects to borrow or how the proceeds will be allocated across projects.
The company is one of only two publicly traded US companies with top-tier AAA ratings from Moody’s Ratings and S&P Global Ratings, alongside Johnson & Johnson. Those ratings provide important credit context for a sale that spans maturities as long as four decades: buyers are assessing Microsoft’s ability to meet payments over time, while the company is seeking terms that fit its financing needs.
Wells Fargo, JPMorgan Chase and UBS are managing the offering. Proceeds are intended for general corporate purposes, including capital expenditures. The company has not identified a specific project or spending category that would receive the funds, so the sale should be read as broad financing rather than a dedicated bond tied to a named AI investment.
A test of demand for AI-related financing
The proposed sale follows a period in which major technology companies have sought debt to help fund investment in artificial intelligence. For Microsoft, the scale of the borrowing plan arrives as investors debate whether the spending by the industry can be sustained. The bond deal cannot settle that debate on its own, but its final size, pricing and demand would provide a market signal about the willingness of buyers to finance a large technology issuer at this point in the spending cycle.
The offering would be the first from a blue-chip hyperscaler since Alphabet priced US$25 billion of debt on Aug 6. That recent transaction gives buyers a nearby point of comparison, although the companies’ financing needs, debt terms and individual credit profiles are not necessarily the same. Microsoft’s sale will add another data point on the volume of capital large technology firms can raise in the bond market.
There is a distinction between demand for a company’s debt and confidence in every project it may fund. Buyers can be attracted to Microsoft’s credit quality and the range of maturities while still questioning whether industry-wide AI spending will generate returns that justify its scale. The sources did not provide demand figures for Microsoft’s proposed sale, and the final terms remain subject to change.
What the terms will reveal
The most useful details to watch are the final amount raised, the pricing across the tranches and the level of demand at different maturities. A sale near or above the stated minimum would show that Microsoft secured substantial funding, while pricing relative to Treasuries would indicate the yield premium buyers accepted. The initial talk for the 2066 note is only a preliminary reference point, not the final spread.
Microsoft and the banks either declined to comment or did not immediately respond to queries. Until final terms are known, the proposed US$25 billion minimum remains a guide to the company’s financing ambition, rather than a completed borrowing total. The deal’s broader significance will rest on both its execution and what its pricing says about appetite for long-dated debt from companies funding the AI investment cycle.
