Bill Ackman says permanent capital is his edge in short-term markets

Pershing Square's Bill Ackman, questioned by Norway's sovereign wealth fund CEO Nicolai Tangen, argues that permanent capital is an edge as AI and indexation shorten everyone else's horizons.

Bill Ackman says permanent capital is his edge in short-term markets

Recorded 28 October 2026 · 53 min

Bill Ackman, founder of Pershing Square, runs a portfolio of 12-14 investments and argues that his decisive edge is structural rather than analytical: permanent capital that lets him own great businesses when short-term holders are forced to sell. Interviewer Nicolai Tangen, who runs Norway's sovereign wealth fund, credits him with compounding at 16% over a long period.

The tension is that Ackman sees AI, indexation and leveraged short-term money making markets more volatile, which creates the discounts his strategy feeds on. He also expects AI to turn intelligence into a commodity. The conversation also covers how he tests conviction, his shift away from combative activism, and a personal turn toward brain-recovery research.

  1. Structure over sector — ▶ 1:02

    Ackman defines a great business as one he could own through a 20-year market closure with enormous certainty that it would still be valuable. The ideal resembles a royalty collector or annuity: it grows at a high rate for a long time and does not need its cash reinvested. He says structure matters more than industry. McDonald's is a restaurant business, but also a real estate business and a franchising operation. He estimates only a couple hundred to 300 truly great businesses exist. They rarely trade at a great price, which is why Pershing Square concentrates and writes large checks.

  2. Predictability as the filter — ▶ 7:34

    Pershing Square converted its principles into a checklist. The first test is whether the firm can model a business over 10, 15 or 20 years, because value is the present value of lifetime cash flows. If it cannot model the business, it does not look at it. It also wants a moat and avoids exposure to commodity, interest-rate and regulatory factors it cannot control. Ackman contrasts this with funds that trade on earnings beats and misses or expected news events, which the firm deliberately ignores.

  3. No individual P&Ls — ▶ 9:07

    The firm has 48 people, nine of them investment professionals, and one portfolio of 12-14 investments. Nobody is paid on an individual P&L. Ackman argues the typical hedge fund rewards analysts for winning capital, which pushes them to lean into their own ideas. At Pershing, two people do the deep work, two do partial work, and the rest of the team has nothing invested before judging a presentation. Objections trigger more diligence. Ackman has the final say but cannot recall an investment in the last decade without a collective view.

  4. AI shortens market horizons — ▶ 13:48

    Ackman says AI is making market participants shorter-term: a 10-K can be read instantly, and a great deal of capital is hunting for a short-term edge. His response has been to buy after sell-offs tied to spending. He bought Amazon after Trump's tariff announcements, and Meta and Microsoft after they disappointed investors by committing more capex than expected, in Microsoft's case citing demand it could not otherwise meet. Those holdings are about a third of the portfolio. He adds that every business is AI-related, or should be, or will be disrupted by AI.

  5. Intelligence as commodity — ▶ 15:08

    Ackman expects AI to give almost everyone access to very low-cost, very high intelligence. If intelligence is a competitive advantage and becomes a commodity, he argues, creativity is what remains for humans. He doubts AI can be creative yet: nothing read before Einstein would have yielded relativity. He also predicts abundance, with an explosion of entrepreneurship and of global GDP growth. These are forecasts supported by an illustration rather than evidence, and the timing and mechanism of the growth are not specified.

  6. Activism without breaking doors — ▶ 17:00

    Ackman's last activist investment launched in 2016. He says CEOs now often send thank-you notes when he takes a stake, where once he might not have received a return call. He credits activism's broader acceptance, his firm's reputation and his familiarity with every CEO in America. He also says market structure changed: indexation reduces float and leveraged short-term capital adds volatility, so a quality business that once fell 3-4% on a miss can now fall 30-40%. That makes durable growth companies available at a discount, and he is content as a quiet owner.

  7. Founder control and succession — ▶ 23:10

    Ackman believes founder-controlled companies, citing Warren Buffett, Sam Walton and Elon Musk, can make smarter long-term decisions in a short-term market. He doubts the next generation should inherit that control, prefers one share, one vote, and generally avoids controlled companies unless the controller is a phenomenal CEO. He also ranks CEO quality below business quality, growth and durability, since a weak CEO can be replaced. Great businesses usually reach attractive prices, in his experience, because management has made a series of mistakes.

  8. Permanent capital as arbitrage — ▶ 25:45

    Ackman says Buffett, in 1969, gave up a right to 25% of profits over a 6% return, returned investor capital, and took control of a textile business on a $100,000 salary with no incentive fee. His reading is that Buffett concluded capital that could vanish would impair compounding. Ackman says Pershing's permanent capital let it deploy aggressively during COVID without worrying about month-end redemptions. He calls the result "time arbitrage", and says outside sovereign wealth funds very little capital in asset management is permanent.

  9. Howard Hughes becomes insurer — ▶ 28:36

    Ackman calls Howard Hughes his version of Buffett's textile business: a good real estate operation, but one where the market assigns a high cost of capital that is hard to exceed. The plan is to shift capital out and into insurance, aiming for a company that is 80%+ insurance and about 20% real estate in a decade. He distinguishes the approach from Apollo's levered spread model. His insurer underwrites property-casualty risk with much lower leverage, holds float in short-term Treasuries, and invests part of the equity in common stocks.

  10. Steelman before conviction — ▶ 34:21

    Ackman's test for investment conviction is to find the best short seller of something he owns and try to rebut each argument. If he can, he can be more confident. He applies the same rule to other beliefs, using X, where he follows about 1,000 people, to find the most articulate voices on each side of an issue. He argues that media owners shape coverage and that engagement-driven social platforms push people toward their existing views. He would like a button that surfaces the best counterargument to any post.

  11. Brain recovery as a bet — ▶ 40:09

    After his 26-year-old daughter suffered a brain hemorrhage, Ackman concluded the field of brain rehabilitation is underserved, partly because many neurosurgeons and neurologists are, in his word, nihilists. His daughter is regaining function, though he says she has lost roughly 98% of her vision. He has assembled a 3.4 acre New York site with a 400,000 foot biotech building and is recruiting to run an institute. He predicts that AI, better signal interpretation and brain-computer interfaces will let the blind see and paraplegics walk in years, not months.

The open question. Ackman's framework demands businesses he can model 10-20 years out, yet he says every company is either AI-related or will be disrupted by AI, and about a third of his portfolio sits in three firms spending heavily on it. The interview does not reconcile these claims. It also does not examine whether his discounts depend on the short-term, leveraged capital he criticizes, and what happens to the opportunity if that behavior changes or permanent capital becomes less scarce.
