Bill Ackman, CEO of Pershing Square Capital Management, has been active in several media appearances in mid-2026 discussing his investment strategy, market views, and the recent IPO of Pershing Square USA, a closed-end investment company listed on the New York Stock Exchange. Ackman described the IPO as the largest closed-end IPO ever but expressed disappointment with its trading price. He stated that his firm's strategy is to construct a concentrated portfolio of durable growth companies and that he would have returned outside capital sooner to focus on a permanent capital structure, which he called a "huge advantage" for long-term investing. Ackman said he is bullish on large technology companies including Meta, Microsoft, and Amazon, which he described as being perceived as "old-fashioned" by the market and therefore trading at attractive valuations. He expressed skepticism about the business models of some frontier AI model companies, stating he worries about "the Open AIs of the world" due to competition from open-source models. On geopolitical risks, Ackman said he believes the Iran conflict is "weeks as opposed to many months away from resolution" and that its resolution would lead to a "massive peace dividend." He also said the biggest risk to markets is the presence of "very levered players" vulnerable to an extrinsic shock.
