A change is this filing measured against the one before it. Est. amount moved is the shares added or sold, priced at the Jun 30, 2026 close. An estimate: a 13F gives no trade prices or dates. For a sold-out position, its value at the previous quarter end.
Questions
What does Bill Ackman hold?
Bill Ackman disclosed 14 positions worth $19.5B in the Q2 2026 13F filing. The largest is UBER at 12.7% of the disclosed value. A 13F lists US-listed stock and options on it; short sales and cash are not in it.
What did Bill Ackman buy and sell last quarter?
Comparing the Q2 2026 filing with the quarter before, the largest moves were opening a position in V, opening a position in MA, opening a position in SPGI and opening a position in NFLX. Changes are measured against the previous filing, not against trades, because a 13F does not disclose trades.
How current is this?
This is the Q2 2026 filing, covering positions held on Jun 30, 2026 and filed with the SEC on Aug 14, 2026. A 13F is due 45 days after the quarter ends, so the most recent filing is always at least six weeks behind the market, and the manager may have changed the book since.
