The triple-A rated company is seeking at least $25 billion across up to 10 tranches, a day after spending less than expected on data centers. Treasury yields held lower, but investment-grade bond funds gave up their morning gains.
For most of this year, the question about artificial-intelligence spending has been whether it pays off. On Thursday the question shifted to who lends the money, and at what price.
Microsoft is looking to raise at least $25 billion in its first U.S. investment-grade bond sale since 2017, Bloomberg reported, citing people familiar with the deal. The offering could come in up to 10 parts with maturities from two to 40 years, with initial price talk of up to 1.35 percentage points over Treasuries on the longest note, due in 2066. Proceeds are for general corporate purposes including capital expenditures. The bonds are expected to be rated Aaa and AAA and to settle on Nov. 4. Wells Fargo, JPMorgan and UBS are managing the sale.
The timing is notable. On Wednesday evening, Microsoft reported capital spending of $45.2 billion for its fiscal first quarter, about $5.5 billion below what analysts expected, which it attributed to late deliveries of third-party data-center capacity. It guided to more than $50 billion this quarter and trimmed its calendar 2026 spending outlook to about $170 billion, from about $175 billion, citing the same delays. The company generated $18.6 billion of free cash flow in the quarter, so it is not borrowing out of necessity. It is choosing to fund part of the build-out in the bond market.
A second hyperscaler, a different balance sheet
Alphabet has already gone further. In the third quarter it raised about $28.7 billion from bond sales and $12.4 billion by selling shares, against free cash flow of negative $9.1 billion, and its long-term debt reached $125.1 billion, up from $46.5 billion at the end of 2025. Alphabet priced a $25 billion bond deal on Aug. 6.
Microsoft's deal brings the strongest balance sheet in the group to the same market. That changes the test. Investors are no longer only asking whether one company can afford its spending. They are being asked to absorb a growing supply of very long-dated technology debt.
A central banker names the channel
In Frankfurt, European Central Bank President Christine Lagarde told reporters after Thursday's rate decision that debt issuance by hyperscalers was one of the factors behind the rise in bond yields, according to FXStreet's live account of the press conference. The ECB's formal statement did not single out technology companies, but it warned that "intensifying spillovers in global bond markets could tighten financing conditions."
U.S. Treasury Secretary Scott Bessent has taken the opposite view of the risk. Asked on Wednesday about double-digit yields on some AI-related debt, he said: "I don't think it's problematic at all because, you know, we're seeing that the neo-clouds are a small component of the overall ecosystem." He added: "We're still seeing the financing getting done."
What the market did
Treasuries held most of their gains. The 10-year yield was about 5.00% in early afternoon, down about 4 basis points on the day, and the 30-year about 5.34%, down about 2 basis points. A long-term Treasury fund was up about 0.3%.
Corporate credit was weaker. The largest investment-grade corporate bond ETF was down about 0.1% in early afternoon after trading about 0.3% higher in late morning, and the main high-yield ETF slipped about 0.2% after being flat. The turn came as Microsoft's deal was in the market, but also as technology stocks extended their losses, so the timing alone does not establish a cause.
Healthy access or growing supply?
The case that this is healthy: a triple-A borrower with strong cash flow is borrowing at initial price talk ranging from about half a percentage point over Treasuries on two-year notes to as much as 1.35 points on 40-year debt, Treasury yields fell on the day, and the Treasury secretary says financing is getting done.
The case that it is a new source of pressure: the largest technology companies are now funding capital spending with long-dated debt and, in Alphabet's case, new shares; a central bank president has publicly linked that borrowing to higher yields; and credit funds gave back their gains on the day the biggest borrower came to market.
What to watch
Final size and pricing of Microsoft's deal, including how far the 40-year note tightens from initial talk; Amazon's capital spending figures after Thursday's close; Treasury's borrowing estimates on Nov. 2; and the Nov. 4 quarterly refunding, which falls on the same day Microsoft's bonds settle.
