- Pershing Square will file a regulatory disclosure on Friday revealing a new stake in Microsoft.
- Microsoft's stock has fallen roughly 15% this year, prompting Ackman's view that the company is at a “highly compelling valuation”.
- Bill Ackman highlights Azure and the M365 Copilot suite as core to enterprise AI adoption and backs the $190 billion 2026 spending plan.
- OpenAI partnership restructuring is framed by Ackman as a strategic shift toward a more open, multi‑model architecture rather than a concession.
- Microsoft's shares rose more than 1% after the announcement, and analyst Matt Britzman says the current valuation is among the lowest in a decade and unjustified.
Why it matters: Pershing Square's new Microsoft holding validates its belief that the 15% stock decline created a bargain, prompting a 1% share price uptick that benefits existing shareholders while reinforcing the fund's reputation for spotting AI‑driven value.
