John Paulson made nearly $20 billion in two years by betting against subprime mortgage bonds with credit default swaps, a contrarian trade in an industry where he had no experience. The Greatest Trade Ever was made by an unknown, small-time hedge fund manager using an obscure strategy. Its only rivals are David Tepper’s $7 billion financial crisis recovery bet and George Soros’ $2 billion bet against the pound.
This article covers what Paulson noticed in the housing market, how credit default swaps worked in his favor, how he got through years of rejection, and why contrarian investing is a mindset rather than a strategy.

1. The contrarian idea behind the trade
Contrarian investing treats the market like a mad man you should not pay attention to. People follow each other even when they think they are following data, and they swing between euphoria and panic. That swing creates mispricing, where assets are overvalued or undervalued relative to their true worth.
From 2000 to 2006 the US market was in a euphoric state. Housing prices usually rise 3% to 5% a year. This time they rose 10% a year, for two reasons: banks handed credit and mortgages to people who could not afford them, and credit rating agencies gave those mortgage packages AAA ratings, so everything looked great.
2. What Paulson noticed: the subprime boom
From his office on Madison Avenue, Paulson noticed a strange trend. Loans go to two kinds of borrowers. Prime borrowers are financially stable with credit scores usually above 660. Subprime borrowers have scores under 620, and to offset the risk their loans carry higher interest rates and aggressive terms like prepayment penalties.
Between 2000 and 2006, subprime loans tripled, and what people owed on their homes doubled from $4.8 trillion to $9.8 trillion. Paulson had little real estate experience, so he hired an analyst, Paolo Pellegrini, to research it in depth.
They found that banks no longer cared who they approved. Traditionally a bank lent responsibly and collected payments over 30 years. Now it could sell the loan to Wall Street and get its money back immediately, so cheaper mortgages meant more customers and instant cash, and banks approved nearly everyone. Two things made this possible: in the late 1990s Congress removed a law that kept regular banks and investment banks separate, and after 9/11 the Federal Reserve cut interest rates, making mortgages much cheaper.
3. The CDO smoothie
The banks were using collateralized debt obligations, or CDOs, to turn loans into investments. A CDO bundles mortgages, corporate loans and bonds into one pool and sells pieces to investors. Think of a smoothie: apples are home mortgages, bananas are corporate loans, berries are student loans. Blend them together and nobody notices that some of the fruit is spoiled. Then pour the smoothie into cups called tranches, French for slices.
Wall Street sold these slices to investors promised monthly income from mortgage payments, and those investors used pension funds, insurance companies, hedge funds and other government funds, so they were not really using their own money. The fruit was rotten, banks kept blending, Wall Street kept selling and investors kept buying with other people’s money.
The watchdogs were supposed to be the rating agencies, but Paulson and Pellegrini found they were giving these CDOs AAA ratings. That told them the collapse was a matter of when, not if.
Everyone in the chain was paid before the risk showed up, so nobody had a reason to look closely.
4. The hard years before the payoff
Paulson was smart: he graduated top of his class at New York University and in the top 5% at Harvard Business School. After graduating he went into management consulting, where he spent a good few years enjoying the good life, then started his own hedge fund, Paulson & Co, in 1994. No clients came in.
The video notes that when everyone else seems to be soaring while you run to catch up, self-doubt sets in, and the longer you stay stuck, the harder it is to get out. In Gregory Zuckerman’s book The Greatest Trade Ever, Paulson describes this as a lonely, demoralizing period of constant rejection. He said two people kept him going: his dad, and Winston Churchill, whose 1941 Never Give In speech pushed him on.
He started the firm with $2 million and one employee. It took a year to land the first client, and although he managed tens of millions, his funds netted about 5% a year for clients, well under the 9% average of other funds.
The trade of a lifetime came after years of being ignored.
5. How credit default swaps made $20 billion
That changed when he started buying credit default swaps on subprime mortgage loans. Few investors had heard of them. Paulson found them only because his research explained the surge in subprime lending. A credit default swap, or CDS, is insurance on a bond: if someone cannot pay the mortgage, the CDS pays out, and you pay small monthly premiums. Unlike normal insurance, you do not have to own the bond. It is like buying fire insurance on other people’s houses because you know they will burn down.
He bought CDS contracts from big financial companies like AIG and investment banks, paying regular fees. When the housing market collapsed and the bonds lost value, the sellers had to pay him billions, even though he never owned the mortgage bonds and never shorted the housing market directly.
The contracts were cheap because nobody believed they would pay out. They were mostly used by banks to protect against a company failing to repay, and almost nobody used them against mortgage-backed securities, since everyone believed housing was safe. They were also sold privately, not on the stock market, so they were nearly impossible to track, and even the firms selling them did not fully understand how much they might owe.
Paulson did not need the whole market to collapse, only enough bad loans inside certain bonds to fail. Other investors betting on falling home prices only made money after the crash had started, but his bet on the riskiest bonds paid off sooner. Michael Burry made $700 million, but began betting aggressively later, when the people meant to pay out were already struggling. Paulson’s exit was timed just before the full crash, locking in profit before CDS premiums became expensive and crowded.
In 2007 alone he made $15 billion for his fund and personally earned $4 billion, the largest one-year payout in hedge fund history.
A small premium, a bet that looked absurd, and a very large payout.
6. Why contrarian investing is a mindset
National housing prices had never gone down in America. It had happened in specific states, but a nationwide collapse seemed impossible, and people said too big to fail. Paulson’s all-in bet looked absurd, and had he been wrong it would have destroyed his reputation and career.
A strategy is a neat plan: if X happens, do Y. A mindset is how you approach decisions under pressure. Contrarian investors are comfortable being uncomfortable and do not need others to agree with them to feel confident. That takes experience, emotional control and strong belief in your view even when the crowd says you are wrong.
David Dreman, a value investor focused on market psychology, wrote five books on contrarian strategies between 1977 and 2012. In his fourth he collects quotes showing how experts fail to predict big shifts. In 1977 Ken Olsen, founder of Digital Equipment Corporation, said there was no reason anyone would want a computer in their home. In 1903 the president of Michigan Savings Bank warned a lawyer off Henry Ford’s company, saying the horse was here to stay and the automobile was only a novelty.
Dreman’s point: the more widely shared a belief is, the more dangerous it becomes. When people accept a belief as fact, it stops being questioned, everyone acts on it, prices move, and the belief seems even more true. Markets move on risk, behavior and surprise, because certainty is already priced in. When a widely held belief turns out wrong, everyone is on the same platform and nobody is left on the other side of the trade, so people panic together. Dreman says that when everyone moves toward or runs from the same platform, you should go the opposite way because that is where the profit is.
7. Why it is so hard to do
The foundation of the contrarian approach, and what Paulson did, is to ignore the hype, not trust what everyone else is doing, and rely on your own real-world observations instead of models or assumptions.
That is psychologically uncomfortable. It means buying stocks everyone hates, investing when the news is bad and holding when others panic. People are wired to follow the crowd: fear kicks in when markets fall, and FOMO takes over when others are making money. Entering early, being wrong at first and standing alone is painful, which is why most people never stick with it.
Paulson had no real estate experience, unlike Michael Burry, and no insider knowledge, unlike Deutsche Bank, and still went all in while the world stood on a different platform. Then he watched that platform take strain and got out just before it collapsed and people ran to his side.
Humility, talent, confidence, self-belief and instinct add up to $20 billion.
What made the trade the greatest of all time
His lack of knowledge in the industry, his ability to spot something wrong, his realization that he needed an expert to dig in, and his determination to understand it all mattered. So did his resolve to go all in when everyone else did the opposite, and his timing in getting in early and recognizing when the tide would turn.
The video’s closing question is whether those are skills worth honing, and it also asks whether the market will always go up, since Dreman shows that experts can be wrong.
