William A. Ackman: trading record in brief
William A. Ackman is a declared insider at 3 companies (chief executive); the most frequent names are Pershing Square USA, Ltd., Pershing Square Inc. and Pershing Square SPARC Holdings, Ltd./DE. Between 21 April 2026 and 17 August 2026, the trades on record add up to 7 filings.
Purchases make up the whole of the open-market record (5 purchases, €205.4M). Unlike grants, an open-market purchase is paid for by the insider, at the market price.
In size, the median ticket on the buying side is €17.9M. Of 5 purchases, 5 formed part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.
Most recently, on 19 August 2026, the filings show a transaction in Pershing Square Inc. The last insider purchase was made public on 1 May 2026, 170 days ago. Typically, a trade is published a median of 1 day after it takes place. Section 16 rules allow two business days to file each Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
