Twitter Thread: The COVID Warnings
The Public Alarm That Preceded the Trade
In the days around his CNBC appearance, Ackman used Twitter to argue for an immediate national lockdown, predicting catastrophic economic and human costs if the virus were allowed to spread unchecked. The threads, dismissed by many at the time as hysteria, read today as a remarkably accurate forecast of both the pandemic and the policy response. They are the public record of the information edge behind the greatest trade of his career.
“[2020-03-18 11:51:47 UTC — status/1240244507246919681] Mr. President, the only answer is to shut down the country for the next 30 days and close the borders. Tell all Americans that you are putting us on an extended Spring Break at home with family.”
Summary
On March 18, 2020, the same morning as his emotional CNBC appearance, Bill Ackman returns to Twitter after a long silence to address President Trump directly. The COVID-19 pandemic has already triggered a rolling market collapse, but U.S. policy remains piecemeal — city-by-city shutdowns, open borders, no national wage support. Ackman treats the platform as a direct channel to the Oval Office, bypassing the financial press to make a single, urgent policy argument before the trading day ends.
The thread's logic is brutally simple. The only way to avoid both mass death and economic ruin, Ackman argues, is a controlled, thirty-day national shutdown paired with closed borders and a rent-interest-tax holiday. He frames uncontrolled spread as the real economic risk: every day of delay multiplies infections exponentially, deepens the eventual shutdown, and destroys the economy. The tweets do not hedge; they predict thousands, then hundreds of thousands, then millions of lives lost if leadership fails.
Read in real time, the thread landed as a public freak-out from a hedge-fund manager. Critics accused Ackman of fear-mongering while positioned for a crash. What the tweets actually reveal, especially the evening clarification, is that Pershing Square was already buying stocks. The thread was the public-policy counterpart to a private trade: credit hedges had paid off, and the same concentrated long book — Hilton, Restaurant Brands, Starbucks — was being added to at panic prices. The market impact was polarized outrage; the portfolio impact was structural.
With the benefit of months, not years, the thread looks less like hysteria and more like a compressed forecast. A national shutdown did come, albeit later and patchier than Ackman wanted; the economy did crater and then recover sharply on stimulus; the asymmetric hedge did close for $2.6 billion. The lasting point is not that Ackman called every detail correctly — he did not — but that he was willing to use his public platform to argue for a policy response that would also make his own insurance position expire worthless.
On the only answer to COVID-19:
"Mr. President, the only answer is to shut down the country for the next 30 days and close the borders. Tell all Americans that you are putting us on an extended Spring Break at home with family. Keep only essential services open. The government pays wages until we reopen."
On exponential cost of delay:
"With exponential compounding, every day we postpone the shutdown costs thousands, and soon hundreds of thousands, and then millions of lives, and destroys the economy."
On buying the bargains:
"That is why we are buying stocks. These are bargains of a lifetime if we manage this crisis correctly."

[2020-03-18 11:51:47 UTC — status/1240244507246919681] Mr. President, the only answer is to shut down the country for the next 30 days and close the borders. Tell all Americans that you are putting us on an extended Spring Break at home with family. Keep only essential services open. The government pays wages until we reopen.
[2020-03-18 11:51:48 UTC — status/1240244508543066112] No one defaults, no one forecloses. A 30-day rent, interest and tax holiday for all. The shutdown is inevitable as it is already happening, but not in a controlled fashion which is extending the economic pain and amplifying the spread of the virus.
[2020-03-18 11:51:48 UTC — status/1240244509344235526] With exponential compounding, every day we postpone the shutdown costs thousands, and soon hundreds of thousands, and then millions of lives, and destroys the economy.
[2020-03-18 11:51:48 UTC — status/1240244510233432064] Please send everyone home now. With your leadership, we can end this now. The rest of the world will follow your lead. A global Spring Break will save us all.
[2020-03-18 12:00:54 UTC — status/1240246799652335622] Mr. President, the moment you send everyone home for Spring Break and close the borders, the infection rate will plummet, the stock market will soar, and the clouds will lift. We need your leadership now!
[2020-03-18 18:55:40 UTC — status/1240351178933895169] Some investors have been confused by remarks. To clarify, I am confident the president will do the right thing in temporarily shutting down the country and closing the borders. If that happens, we can win the war against the virus and the markets and the economy will soar.
[2020-03-18 18:55:40 UTC — status/1240351180129284098] That is why we are buying stocks. These are bargains of a lifetime if we manage this crisis correctly.
Key Themes
- Asymmetric Hedging — the credit protection that turned a roughly $27 million premium into $2.6 billion in three weeks, funding equity purchases at the bottom
- Volatility vs. Permanent Loss of Capital — distinguishing the temporary markdown of Hilton and restaurant stocks from their long-term intrinsic value
- Hell Is Coming — the CNBC interview given hours after this thread, making the same argument with the same raw urgency
- Capital Allocation Discipline — redeploying hedge proceeds immediately into the existing long book rather than raising cash
- Concentration as Risk Mitigation — why a concentrated equity book requires catastrophe insurance rather than dilution
Context & Significance
This thread belongs to Act IV, the renaissance, and it captures the mindset of an investor who had spent the previous four years rebuilding around the Eight Commandments and permanent capital. The Valeant valley taught Ackman that conviction without a kill switch is dangerous; the COVID crisis showed what the kill switch looks like in practice. Rather than sell the concentrated equity book into a panic, he had bought asymmetric protection when it was cheap, and the moment the thesis paid off he became a buyer of the same businesses the market was abandoning.
The honest retrospective is that the tweetstorm was widely misunderstood. Condemned as alarmist, it was in fact the public argument for the policy response — a short, hard shutdown — that would save both lives and the economy. Ackman was not betting on hell; he was insured against it and pleading for the action that would make the insurance expire worthless. Read alongside his CNBC appearance from the same day and the 2020 annual report, the thread documents how the renaissance portfolio was designed to survive volatility, and how Ackman used the volatility to add to positions he already believed were permanent.
