Bill Ackman’s bold attempt to take his hedge fund public in 2024 ended in one of Wall Street’s most talked about retreats. He wanted to raise up to $25 billion for a New York Stock Exchange listing. He walked away with nothing. Now, barely two years later, the billionaire investor has filed a fresh SEC registration to list Pershing Square on the NYSE, this time with a completely different playbook.
How the $25 Billion IPO Dream Fell Apart
After filing the prospectus in early 2024, Ackman ended funding for Pershing Square USA and withdrew its IPO in July of that year, as lack of investor interest made him scale back its size from $25 billion to $2 billion.1
Ackman’s big idea was that he would parlay his notoriety on X, where he has 1.3 million followers, into becoming the next Warren Buffett.2 Actually raising the money, however, proved much harder than he’d anticipated, partly because of his own unforced errors.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.2 Pershing Square’s Bill Ackman listed his hedge fund in Amsterdam in 2014, but for most of the past decade, it has been trading unhappily well below its net asset value.2
The collapse exposed a deeper truth about why hedge funds struggle to go public. There’s a reason so few hedge fund firms seek a stock market listing: investors don’t like them. The allure of an economic interest in these money machines is tempered by the risks.3
Here are the key risks that spooked investors in 2024:
- Key person risk: Many such firms are dominated by a single executive.3
- Earnings volatility: Most profits stem from incentive fees, typically set at 20% of fund performance, but these are unpredictable and in bad years can disappear altogether.3
- NAV discount trap: Closed-end fund shares often trade below their actual asset value, punishing long-term holders.

What Changed Between 2024 and 2026
Ackman did not sit still after the failure. He pivoted quickly.
After a plan to raise up to $25 billion to list its closed-end fund fell apart in 2024, Pershing Square pivoted to boosting its stake in Howard Hughes Holdings as a platform for acquiring majority stakes in other companies.4
He also laid the groundwork for a second attempt. In 2024, Ackman agreed to sell a 10% stake in Pershing in a private deal that valued it at more than $10 billion ahead of the planned IPO.5 That deal gave outside investors a taste of what a public Pershing Square could look like, and it set a price floor for the eventual listing.
By late 2025, reports surfaced that Ackman was preparing to try again. This time around, Ackman has sweetened the deal for investors who put money into the new fund by offering free shares of Pershing Square, which would also go public.1
Ackman’s New Dual IPO Structure Explained
Outspoken investor Bill Ackman is taking a step toward his long-held ambition of building a publicly traded investment vehicle modeled on Warren Buffett’s approach, filing to list his hedge fund firm Pershing Square Capital Management on the New York Stock Exchange.4
The 2026 plan looks nothing like the 2024 version. This time, Ackman filed for a dual listing. 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, allowing investors to buy or sell each independently.4
Here is how the deal works:
| Feature | Details |
|---|---|
| Target raise | $5 billion to $10 billion |
| Share price | $50 per PSUS share |
| Bonus shares | 20 PS shares for every 100 PSUS shares bought |
| Private placement | $2.8 billion already secured |
| Private investor bonus | 30 PS shares for every 100 PSUS shares |
| Lead banks | Citigroup, UBS, Bank of America, Jefferies, Wells Fargo |
| NYSE tickers | PS (management company), PSUS (closed-end fund) |
Unlike the 2024 attempt, which relied heavily on retail enthusiasm that failed to materialize at scale, the 2026 filing showcases a diversified institutional front.6 This group, which includes family offices (30%), pension funds (25%), and insurance companies (22%), provides a stabilizing foundation for the IPO.6
There will be a 2% management fee and no performance fee.7 That is a massive change from the typical hedge fund model and directly addresses the earnings volatility that scared off 2024 investors.
Why Hedge Fund IPOs Remain So Rare
Publicly traded hedge fund managers are rare, but not unheard of. Man Group has been around for years, with AUM around $200 billion, although they operate outside most U.S. retail investors’ radar.8
Listing alternative asset managers on exchanges remains relatively uncommon. This changed briefly in 2006/2007 when, among others, Partners Group, Absolute Capital, BlueBay and GLG as well as Och Ziff and Fortress Group secured IPOs.9 Since the credit crunch the IPO window has remained firmly closed.9
The hedge fund business model is the problem. Unlike private equity firms with long-duration fee streams, hedge fund revenues can be more cyclical, tied closely to performance and assets under management. Convincing public investors to assign premium multiples to those earnings may prove challenging.10
Private equity giants like Blackstone and Apollo have thrived as public companies because their locked up capital and management fees create steady, recurring revenue. Hedge funds offer the opposite. Redemptions can come at any time, and a bad quarter can wipe out an entire year of performance fees.
“Pershing Square has been a long-term beneficiary of the opportunity to buy superb companies at bargain prices driven by macro events.” Ackman wrote this in a letter to investors, pointing to the current market volatility as a buying opportunity rather than a threat.11
The Risks Ackman Still Faces in 2026
Even with a smarter structure, Ackman faces real headwinds.
With the U.S. war on Iran and widespread market volatility, 2026 is a nervy time to float an S-1.8 Wall Street is quietly starting to trim as geopolitical risk threatens to delay M&A pipelines, stall IPOs, and keep the Fed on hold longer than anyone wants.12
Pershing Square’s own performance has wobbled. The fund posted a negative 7.7% return in February and is down 10.1% year to date through February 28, 2026, while the S&P 500 gained 0.3%.13 That drawdown is a direct result of heavy concentration. PSUS employs a concentrated large-cap growth strategy with leverage, but faces high fees and potential for NAV discounts.14
Some analysts are already urging caution. One major investment research platform rates both PSUS and PS a Hold due to high fees and uncertain PS valuation, recommending investors revisit on deep NAV discounts or more attractive pricing.14
Still, the long-term record is hard to ignore. Pershing returned 34% last year, well ahead of the S&P 500’s 17.9% and marking the latest in a near decade long streak of besting the index.7 Since January 2004, the fund has delivered a 16.2% CAGR versus 10.7% for the S&P 500.13
Ackman’s 2024 failure was a hard lesson in how Wall Street punishes overconfidence. His 2026 filing is a quieter, more calculated move built on institutional backing, a creative share structure, and the lessons of a very public stumble. Whether he can pull it off this time will depend on markets that are anything but calm. If he succeeds, it could open the door for other hedge funds to follow. If he stumbles again, it may close that door for a generation. Drop your thoughts in the comments below.
