What it is

Microsoft has committed roughly $13B+ to OpenAI and hosts most of its training/inference on Azure, though a late-2025 restructuring of OpenAI into a PBC loosened Azure exclusivity (OpenAI added Oracle, CoreWeave, and Google Cloud capacity). Microsoft is simultaneously one of the largest Nvidia GPU buyers and is building its own Maia accelerators to reduce dependence. Its capex guidance blew past $80B/year in FY2025 driven almost entirely by AI datacenters.

Amounts keep the filing's own wording (at least, up to, about). They are not added up: a compute commitment, a lease and an equity round are different kinds of money.

Times are New York time. Free sources are pulled on the schedule shown by the pipeline runner (data/corpus/run_pipelines.py), which logs every run; paid sources run only with the owner's yes; filings and newsroom pages are re-read when a new document is filed.

Links come from the AI Systems Map ontology. Deals carry the filing's own wording and a quote, checked against the document; latest source 2026-10-26. Not investment advice.
