Formative Experiences: Book and Side Hustle
During his undergraduate years, Bill Ackman worked for Harvard Student Agencies, selling advertising for the *Let’s Go* travel guides. The commission-based role earned him roughly $14,000—a sum he later described as his first “taste of business success.” His father, co-founder of Ackman-Ziff Real Estate Group, introduced him to Leonard Marks, who recommended Benjamin Graham’s *The Intelligent Investor*. Ackman has repeatedly said the book shaped his value-investing outlook and cemented his admiration for Warren Buffett.
Founding and Growth of Pershing Square
After winding down his earlier venture, Gotham Partners, Ackman launched Pershing Square Capital Management in the mid-2000s. Over more than two decades, the firm expanded into a $35 billion hedge-fund operation. Investors who remained with the firm from its inception have reportedly compounded returns at an average of about 16.5% per year, outpacing the S&P 500’s roughly 10% annual gain over the same period.
Recent Performance and Capital Raising
In 2026 the firm faced a challenging year, with Pershing Square Holdings down 11% year-to-date through February, while the S&P 500 posted a modest 1% gain. Despite the dip, the firm completed a historic capital raise in April, issuing a $5 billion closed-end fund—the largest such listing in U.S. history. The offering includes a structure that grants investors 20 free shares for every 100 purchased, aiming to secure “permanent capital” similar to Berkshire Hathaway.
Impact and Legacy
Ackman’s 2020 bet on corporate credit during the COVID-19 market crash reportedly turned $27 million into $2.6 billion within weeks, illustrating the firm’s capacity for rapid, high-conviction trades. Earlier successes—including a 2016 investment that nearly doubled a $1.2 billion stake in Chipotle and a celebrated activist campaign at Canadian Pacific Railway—have reinforced his reputation as a leading activist investor. The combination of early entrepreneurial exposure, Graham-inspired value principles, and aggressive capital deployment continues to shape Pershing Square’s influence on public-company governance and market dynamics.
