Microsoft targets at least $25 billion in first US investment-grade bond sale since 2017
Microsoft is marketing its first US investment-grade bond sale in more than nine years and is seeking to raise at least $25 billion, according to Bloomberg Technology. The reporting links the offering to funding the artificial intelligence investment boom alongside rivals pursuing similar buildouts. The move follows a week in which filings disclosed Azure revenue of $33.2 billion for the July–September quarter, up 48% year-over-year, and $10 billion in quarterly revenue from commercial arrangements with OpenAI, nearly 11% of Microsoft's $92.3 billion total. Those figures underscore the scale of capital Microsoft is already deploying through cloud and partnership channels. Bloomberg describes active marketing and a minimum fundraising target, not final pricing, bond terms, or confirmed proceeds, so operators should treat the headline size as intent until the sale completes.

Why it matters
Large tech issuers are pairing public debt and equity raises with AI buildouts, which can shift borrowing costs, vendor demand for compute, and how aggressively hyperscalers expand capacity.
Limits and uncertainties
Bloomberg reporting describes marketing and a minimum target, not confirmed pricing, final size, bond terms, or a detailed use-of-proceeds breakdown for the Microsoft sale.
TechCrunch notes it is unclear how much of Microsoft's OpenAI-related revenue came from revenue-sharing versus Azure cloud services.
Azure versus Google Cloud comparisons in TechCrunch rely in part on TechCrunch calculations and differ in segment scope such as Workspace inclusion.
Practical implications
Builders sizing multi-year AI infrastructure plans should watch whether Microsoft and peer issuers close these fundraises and how capital markets react to AI-linked corporate debt.
Operators negotiating cloud commitments may weigh Azure's newly disclosed $33.2 billion quarterly scale and fast growth against limited AI-specific revenue breakdown in the excerpts.
