Bill Ackman: Investment Strategy, What the Market is Missing, How AI Breaks Businesses

Bill Ackman opens by describing his evolution as an investor, explaining that the most significant change over time has been an appreciation for long-term, durable, protected, and non-disruptible business growth. He recounts an early activist campaign at Wendy's International, where he identified that the value of Tim Hortons exceeded the entire market cap of Wendy's, and used public pressure and a Blackstone fairness opinion to force a spin-off — illustrating how his tactics have shifted from aggressive public campaigns to leveraging his established reputation for more collaborative board-level engagement.

On AI, Ackman argues that we are in the greatest era in history to build a business, with unlimited access to compute, capital, and talent — but that this also dramatically raises the risk of disruption for incumbent businesses. He notes that while capital is flowing toward chips, semiconductors, and energy, high-quality companies like Microsoft, Meta, and Amazon are being left behind and are trading at historically low multiples, drawing a parallel to how Berkshire Hathaway was undervalued during the dot-com bubble. He is cautious about SaaS companies with monopolistic pricing and niche products, suggesting they face real disruption risk, while believing platform companies with low per-seat pricing are more defensible.

Ackman reflects on his high-profile CNBC appearance during COVID-19 in March 2020, clarifying that his motivation was less about markets and more about pressuring President Trump to implement a two-week national shutdown to prevent hospital overflow. He explains that valuation acts like a tether or rubber band — when stocks get extremely cheap, there is a psychological and fundamental force pulling them back up, and calling that out publicly can itself catalyze a reset.

On venture-style investing, Ackman explains that companies like SpaceX, OpenAI, and Anthropic should be underwritten using a venture framework — evaluating people, opportunity, context, and deal terms — even though they are late-stage. He is personally invested in X and XAI through an SPV, and praises OpenAI CFO Sarah Friar's articulation of capital allocation strategy, saying it made him more bullish and that she should be CEO.

Ackman endorses the founder-led company thesis, arguing that founders have longer time horizons, larger economic stakes, full authority to make bold decisions, and a track record of making difficult calls — advantages that professional CEOs with short tenures and misaligned compensation structures lack. He cites Zuckerberg's acquisitions of Instagram and WhatsApp as examples of founder conviction paying off.

Regarding Howard Hughes Corporation, Ackman outlines his plan to replicate Buffett's Berkshire Hathaway model: buy a discounted asset-heavy company, inject insurance operations, invest the insurance float in short-term treasuries, and invest equity surplus in common stocks — creating a long-term compounding machine. He traces Howard Hughes back to its origins as a General Growth bankruptcy spin-off and acknowledges it has traded at a persistent discount because of its real estate and development nature. The goal is to transform it into a trillion-dollar compounding entity over 50 years without issuing additional stock.

Finally, Ackman discusses the three ways to invest alongside him: Pershing Square (the management company, which is a royalty on compounding), PSUS (a public vehicle trading at an 18% discount holding his best ideas), and Howard Hughes Corporation. He also reflects on the power of social media, noting that his large Twitter following allows him to communicate his investment thesis directly to millions, though he distinguishes his influence from meme stock dynamics driven by figures like Ryan Cohen.
