Who Is John Paulson?

Early Life and Education
John Alfred Paulson was born on December 14, 1955, in Queens, New York City. He grew up in New York and developed an interest in business and finance.
Paulson attended New York University, where he studied finance and business-related subjects. He later earned an MBA from Harvard Business School.
His education helped provide a foundation for his career in investment banking, private equity and eventually hedge fund management.
How Did John Paulson Start His Career?

In 1994, he founded Paulson & Co., an investment management firm based in New York.
The Trade That Made John Paulson Famous
John Paulson’s biggest rise to fame came during the U.S. housing and mortgage crisis.
In the years before 2008, the U.S. housing market had experienced a major boom. Many financial institutions were heavily exposed to mortgage-backed securities, including securities connected to risky subprime mortgages.
Paulson believed the housing market was overvalued and that problems in the subprime mortgage market could cause a major financial collapse.
His firm used financial instruments called credit default swaps (CDS) to bet against mortgage-related securities.
When the housing market collapsed, the value of many mortgage-related investments fell sharply. Paulson’s positions produced extraordinary profits.
This trade reportedly generated billions of dollars in profits for Paulson & Co. and made John Paulson one of the world’s best-known hedge fund managers.
