Questions

Which hedge funds own MSFT?

Across each manager's latest 13F filing (mostly Q2 2026), 4 of the 18 tracked managers held Microsoft: Pershing Square Capital (15.3%), Altimeter Capital (5.8%), Fundsmith (4.4%), Baron Capital Group (under 0.1%).

Did Pershing Square Capital add or sell MSFT last quarter?

In its Q1 2026 13F, filed May 15, 2026, Pershing Square Capital opened a position; MSFT was 15.3% of its reported portfolio.

What is a 13F and what does it miss?

Managers with $100 million or more in US equities report their long positions on Form 13F each quarter, up to 45 days after it ends. The filing omits short positions, bonds, cash and most foreign listings, and a position may have changed since the quarter ended. Options are excluded here.

From the managers’ Form 13F-HR filings with the SEC, amendments applied, share counts adjusted for splits; GOOG and GOOGL are one position. A record of filings, not a recommendation.
