Madoff investment scandal
investment scandal discovered in 2008

The Madoff investment scandal, sometimes known as Madoffgate, was a financial scandal discovered in late 2008. In December of that year, Bernie Madoff, the former Nasdaq chairman and founder of the Wall Street firm Bernard L. Madoff Investment Securities LLC, admitted that the wealth management arm of his business was an elaborate multi-billion-dollar Ponzi scheme. Madoff founded Bernard L. Madoff Investment Securities LLC in 1960, and was its chairman until his arrest. The firm employed Madoff's brother Peter as senior managing director and chief compliance officer, Peter's daughter Shana Madoff as rules and compliance officer and attorney, and Madoff's sons Mark and Andrew. Peter was sentenced to 10 years in prison, and Mark died by suicide two years to the day after his father's arrest.
Alerted by Madoff's sons, federal authorities arrested Madoff on December 11, 2008. On March 12, 2009, Madoff pleaded guilty to 11 federal crimes and admitted to operating the largest known Ponzi scheme in history. On June 29, 2009, he was sentenced to 150 years in prison, the maximum sentence allowed, with restitution of $170 billion. He died in prison in 2021. According to the original federal charges, Madoff said that his firm had "liabilities of approximately US$50billion." Prosecutors estimated the size of the fraud to be $64.8 billion, based on the amounts in the accounts of Madoff's 4,800 clients as of November 30, 2008.
