Is Bill Ackman buying or selling right now?
Across the reported book, Bill Ackman added to 0 positions and trimmed 2, which makes the latest quarter a net selling one. "Right now" is the important caveat: a 13F is a snapshot as of the quarter end, filed up to 45 days later, so it shows what was held then, not what is held today.
What fund does Bill Ackman run?
The filings on this page come from Pershing Square, SEC CIK 1336528. That is the entity that files the 13F, which is why holdings are reported under the firm name rather than the person's name.
Is this Bill Ackman's current portfolio?
No. It is the most recent one that has been publicly filed. Institutional managers report holdings quarterly on Form 13F, as of the last day of the quarter, with up to 45 days to file. This page reflects the filing dated May 15, 2026 and updates automatically when the next one hits SEC EDGAR.
Does this show Bill Ackman's short positions or options?
Mostly no. A 13F covers reported long U.S. exchange-traded equity positions and some equity options and convertibles. Short positions are not disclosed, and neither are bonds, cash, commodities, currencies, or foreign-listed holdings. A manager with a large short book or heavy non-equity exposure can look very different in a 13F than in reality.
How do I track Bill Ackman's next moves?
This page rebuilds straight from SEC EDGAR, so the next 13F appears here as soon as it is filed. New stakes disclosed between quarters on Schedule 13D and 13G show up on the Smart Money page ahead of the next 13F, because those filings are due within days of crossing a 5% ownership threshold rather than at quarter end.
