He pursued higher education at Harvard College, earning a Bachelor of Arts degree in social studies in 1988. Following his undergraduate studies, Ackman continued his education at Harvard Business School, where he earned his Master of Business Administration (MBA) degree in 1992.
After graduating from Harvard Business School, William Ackman co-founded the investment firm Gotham Partners in 2002 (though general knowledge suggests 1992). Gotham Partners focused on small investments in public companies.
His early career was characterized by a deep dive into value investing and a developing interest in activist strategies, where he would take stakes in companies and push for changes.
The true breakthrough came with the founding of Pershing Square Capital Management in 2004. This firm became the primary vehicle for his activist investing, allowing him to take larger, more influential positions in major corporations.
Pershing Square quickly gained notoriety for its aggressive and often confrontational approach to corporate governance, targeting companies like McDonald's and Wendy's early on.
Ackman scaled his fortune through a series of high-profile activist campaigns, including successful investments in companies like Canadian Pacific Railway and Allergan. These campaigns often involved detailed research, public presentations, and proxy battles.
While some campaigns, such as his short position against Herbalife and his investment in Valeant Pharmaceuticals, faced significant challenges and criticism, his overall track record and the growth of Pershing Square's assets under management solidified his position as a billionaire investor. Recent achievements in 2024 include major investment returns from strategic positions in high-profile companies.
