Bill Ackman's New Closed-End Fund Trades 20% Below IPO Price

Billionaire investor Bill Ackman launched his new closed-end fund, Pershing Square USA (ticker: PSUS), in July 2026, but it is now trading roughly 20% below its IPO price of $50 per share. This weak performance raises questions about the viability of the Berkshire Hathaway-like model.

Fund Details

Pershing Square USA is a closed-end fund that offers investors access to Bill Ackman's concentrated portfolio. Unlike open-end funds, closed-end funds do not redeem shares, so the market price can deviate significantly from net asset value (NAV). Currently, the fund trades at a 20% discount, indicating that investors are unwilling to pay full value for the assets.

Why the Discount?

Several factors may explain the discount:

• Closed-end structure: These funds often trade at discounts or premiums, especially early after listing.
• High expectations: Investors may have overestimated demand for an Ackman fund, leading to a high IPO price.
• Market conditions: Volatility or weak confidence in Ackman's strategy may have weighed on the price.

Comparison with Berkshire Hathaway

The fund is often compared to Berkshire Hathaway (BRK-B) due to Ackman's long-term, concentrated investment style. However, closed-end funds differ from holding companies in that their prices are influenced by secondary market supply and demand, not just asset value.

What It Means for Investors

The current discount could represent a buying opportunity for those who believe in Ackman's ability to generate long-term returns. However, caution is warranted as the discount may persist or widen if market sentiment remains negative. Investors should monitor NAV and portfolio performance before making decisions.
