About Bill Ackman

Bill Ackman runs Pershing Square Capital Management, a concentrated, long-biased activist fund that typically holds fewer than fifteen positions — the 2026 Q1 13F shows eleven, with the top five accounting for roughly 78% of a $13.7B disclosed book. His edge, historically, has been identifying businesses with durable pricing power and then using an activist ownership stake to pressure management on capital allocation or strategic direction. He became widely known for a series of high-conviction macro overlays on top of the equity book: most notably, a CDS hedge on corporate credit indices at the onset of COVID-19 in early 2020 that returned roughly $2.6B on a ~$27M premium outlay, and a subsequent well-publicized short on the CDX at rising rate expectations. Readers parsing the 13F should understand that the filing captures only long equity and certain option positions reported to the SEC — Ackman's macro overlays, interest rate hedges, and short book do not appear, which is why cloned long-only backtests tend to diverge materially from Pershing Square's actual fund returns.

2026Q1 brief

Pershing Square's $13.7B concentrated book got a significant reshuffle in 2026Q1, with MSFT arriving as a new 15.3% position — instantly Ackman's fourth-largest holding — and slotting neatly alongside existing mega-cap tech exposure in AMZN (17.4%) and META (11.1%). The 95% liquidation of both GOOG (trimmed to a rounding-error 0.7%) and GOOGL (0.07%) is striking: Ackman is effectively rotating out of Alphabet entirely while doubling down on the broader software/platform theme via Microsoft, perhaps preferring Azure's enterprise AI positioning over Google's more advertising-dependent revenue mix. HLT (previously 5.6%) was fully exited, ending a hospitality bet that never fit cleanly with the rest of the book. The portfolio now sits at just 11 positions with top-5 concentration at 78%, dominated by BN, AMZN, UBER, MSFT, and QSR. Watch whether MSFT gets scaled further toward a top-3 slot in Q2, and whether the residual Alphabet stub gets cleaned out entirely.
