Microsoft's $25 Billion Bond Offering Draws 4.6x Subscription, Yet 30-Year Spread Exceeds Lower-Rated P&G

Backed by its scarce AAA credit rating and stellar financial results, Microsoft successfully completed a $25 billion bond issuance, one of the most sought-after deals in the history of the U.S. corporate bond market. Yet behind this spectacle, the bond market's selective differentiation among AI hyperscalers has become increasingly clear.

The offering attracted peak orders exceeding $115 billion, with a subscription ratio of 4.6 times. The underwriting team was led by Wells Fargo, JPMorgan and UBS, and narrowed the spread on the longest-dated bonds by up to 30 basis points from initial price guidance.

Microsoft Chief Financial Officer Amy Hood said on this week's earnings call that the company will raise further financing "when it deems the timing appropriate."

However, market participants warned that Microsoft's success does not mean other tech giants will receive equally enthusiastic reception. Recent concerns over AI spending and profitability have weighed on high-risk tech debt—the cost of credit default swaps for Broadcom and SpaceX briefly touched record highs.

Jack Janasiewicz, multi-asset portfolio manager and chief strategist at Natixis Investment Managers Solutions, said, "The credit market is doing a lot of the work of sorting winners from losers; the market remains open to issuance, but not to everyone."

Microsoft shares closed down 0.16% on Thursday.

AAA Rating Advantage: Microsoft's Scarce Status

Microsoft's latest issuance comes nearly eight years after it last tapped the U.S. investment-grade bond market—it raised $17 billion in 2017.

The offering comprised 10 tranches with maturities ranging from 2 to 40 years, with the 40-year bond priced at a spread of about 105 basis points over the benchmark Treasury, notably below Alphabet's roughly 133 basis points on bonds of the same maturity; Alphabet also carries a lower rating than Microsoft.

On the ratings front, Microsoft is the only U.S.-listed company besides Johnson & Johnson to hold top AAA ratings from both Moody's and S&P, a status that gives it a natural advantage in standing out amid crowded tech debt supply.

Brett Kozlowski, a portfolio manager at GW&K Investment Management, said, "The timing of this deal feels quite opportunistic," and strong demand was expected, driven mainly by the market's appetite for "extremely rare long-duration AAA bonds," plus the appeal of yields above 6%.

Microsoft's quarterly results announced on Wednesday also provided strong support for the issuance—cloud revenue grew 48% year over year, and capital expenditure remained within a manageable range, easing investors' concerns about heavy AI spending.

CreditSights analysts noted in a report published on Thursday that the $25 billion bond issuance will raise Microsoft's total lease-adjusted leverage only slightly, to 0.7 times, leaving its balance sheet healthy.

Bond Market Absorption Capacity Nearing Its Limit: Microsoft's 30-Year Spread Higher Than Lower-Rated P&G

Despite Microsoft's smooth sailing, bond supply from the hyperscaler sector as a whole is approaching the limit investors can absorb.

According to Bloomberg-compiled data, as of Thursday, hyperscalers and data center developers had raised more than $313 billion this year through global investment-grade bond issuance, nearly three times the full-year 2025 level, pushing total global bond issuance to a record $6.63 trillion.

Facing market saturation, some large borrowers have begun to cool off voluntarily. Oracle disclosed this week that it has committed to a net debt increase cap of $10 billion through fiscal 2030 to ease investor concerns about its debt expansion; Meta, meanwhile, turned to the equity market and completed a $25 billion equity financing.

Microsoft's own pricing also reflects the market's cautious sentiment. Despite its AAA rating, its 30-year bond spread reached 95 basis points over the benchmark Treasury, higher than the 30-year bond issued the same week by lower-rated Procter & Gamble—which priced at a 60 basis point spread, the lowest premium since 2003.

Ayako Yoshioka, director and senior investment strategist at Wealth Enhancement, said: "For Microsoft's 5-year and 7-year bonds, I would subscribe without hesitation. But once you extend to 30 years, uncertainty at the business model level still needs to be reflected in pricing." Risk Disclosure and Disclaimer
