Bill Ackman’s dream of taking Pershing Square public hit a wall in 2024 when investor demand vanished and his $25 billion IPO target crumbled to zero. But the billionaire hedge fund manager refuses to stay down. On March 10, 2026, he filed for a bold new dual listing on the New York Stock Exchange, this time with a completely different playbook.
How the Original $25 Billion IPO Fell Apart
Ackman had floated a potential size of $25 billion during the marketing of the offering earlier in 2024, which took place in a series of one-on-one meetings and larger town halls.1 It would have been the largest closed-end fund IPO in U.S. history.
The withdrawal came after the anticipated size was slashed twice in just two weeks.1 Pershing Square USA was scaled back to a range of $2.5 billion to $4 billion in a July 24 letter, and finally $2 billion.1
The fund officially withdrew its planned initial public offering in July 2024 after struggling to secure investor backing.2
The core problem was simple. Investors saw little reason to buy in at the IPO price, given the high likelihood that the stock would, like its European sibling, end up trading at a discount.3 With interest rates jumping in recent years, many closed-end funds had traded well below the value of their underlying assets.1
There were also unforced errors along the way. The pulled offering followed Seth Klarman’s Baupost Group deciding against investing in the fund.1 Ackman had publicly touted Baupost’s participation, making the retreat more embarrassing.

Why Investors Said No to Pershing Square
Concerns about after-market performance proved to be a major factor. In meetings with institutions and family offices, investors questioned whether they’d be better served waiting for the fund to trade rather than purchasing shares in the IPO.1
Hedge funds face a unique challenge when going public. Their earnings swing with markets, driven by performance fees that can vary wildly from year to year. Public market investors generally prefer steady, predictable cash flows.
Here is what stacked against Ackman’s original offering:
- Net asset value discount risk: Closed-end funds frequently trade below the actual value of their holdings
- Fee structure concerns: Pershing Square charges management fees plus performance fees on top
- No distribution component: Unlike most U.S. equity closed-end funds, the original offering did not include regular payouts to shareholders
- Competition from safer options: Money market funds and private credit were delivering attractive returns with less risk
Ackman listed his hedge fund in Amsterdam in 2014, but for most of the past decade, it has been trading well below its net asset value.3 That track record gave buyers little reason to trust a New York version would be different.
Ackman Returns With a Revamped Dual Listing
Fast forward to March 2026, and Ackman is trying again with a radically different approach.
He filed to list his hedge fund firm Pershing Square Capital Management on the New York Stock Exchange.4 The transaction involves a dual listing structure. Pershing Square’s common shares and the shares of its closed-end fund, PSUS, will both trade on the NYSE. The securities will be listed concurrently but will trade separately.4
Ackman is seeking to raise between $5 billion and $10 billion for PSUS, with investors able to purchase shares at $50 apiece.4 That target is far more modest than the $25 billion ambition that collapsed in 2024.
The biggest change? A sweetener designed to make the IPO too good to pass up.
The firm expects to deliver 20 shares of Pershing Square Capital Management’s common stock for every 100 PSUS shares purchased in the initial public offering, at no additional cost.4 Private placement investors who committed capital before the filing receive an even more generous 30 shares per 100.5
| Feature | 2024 IPO Attempt | 2026 IPO Filing |
|---|---|---|
| Target Raise | Up to $25 billion | $5 billion to $10 billion |
| Structure | Closed-end fund only | Dual listing (fund + management company) |
| Free equity bonus | None | 20 shares of PS per 100 PSUS shares |
| Pre-committed capital | Minimal | $2.8 billion secured |
| Institutional backing | Weak | Family offices, pensions, insurers |
The investment firm has already secured $2.8 billion in commitments ahead of the offering.4 Unlike the 2024 attempt, which relied heavily on retail enthusiasm that failed to materialize at scale, the 2026 filing showcases a diversified institutional front.5
The Buffett Playbook Behind Ackman’s Vision
By filing to take Pershing Square public, Ackman may have taken the first step toward reaching his biggest goal yet, to create his own “modern-day” Berkshire Hathaway.6
The idea rests on one powerful concept: permanent capital.
Traditional hedge funds like Pershing Square allow investors to pull out their money either quarterly or annually. Fund managers need to keep cash on hand and may have to sell holdings in case their investors flee. Through the dual listing, Pershing will instead have access to capital in its closed-end fund that can’t be directly revoked.6
That structure frees Ackman to think in decades, not quarters.
In a letter to investors, Ackman noted recent market volatility including the war in Iran, and said that unlike operating companies considering IPOs, stock market disruption actually helps Pershing Square’s acquisition program.7
The alternative asset manager has roughly $30.7 billion in total assets under management, with $20.7 billion of that in fee-paying assets as of the end of 2025.8 Since the failed 2024 effort, Ackman has expanded his platform, including taking control of Howard Hughes Holdings and striking a $2.1 billion deal for Bermuda-based insurer Vantage Risk.9
What This Means for the Hedge Fund Industry
This filing fits into a broader industry trend where elite hedge fund managers are moving away from the “2-and-20” fee model in favor of permanent capital vehicles.10
Publicly traded hedge fund managers are rare, but not unheard of.11 Man Group has been around for years, with assets under management around $200 billion, although they operate outside most U.S. retail investors’ radar.11
But pure-play hedge fund listings have a mixed track record for one big reason. Performance fees make quarterly earnings unpredictable. That scares off investors who buy stocks for steady dividends and clean financial statements.
By listing on the NYSE, Pershing Square is inviting a level of public disclosure and regulatory oversight that is uncommon for activist hedge funds. This could pave the way for other high-profile managers to “go public,” potentially opening access to activist investment strategies that were previously reserved for the ultra-wealthy.10
Key takeaway for investors: If Ackman’s dual listing succeeds, expect more hedge fund managers to explore similar permanent capital structures in the coming years.
Key risks include high concentration in a small number of large-cap growth names, elevated fee structure at roughly 3.2% total, and potential failure to hedge effectively during market downturns.12
The 2024 collapse and the 2026 comeback tell the same story from two different angles. Wall Street does not hand out second chances easily. But Ackman has shown he is willing to learn from failure, lower his sights, and redesign the offering to address exactly what went wrong the first time. Whether public investors will finally buy into his Buffett-inspired dream remains the biggest open question in asset management this year. Drop your thoughts in the comments below.
