Bernard “Bernie” Madoff was one of the most respected men on Wall Street. Once the chairman of the NASDAQ stock exchange, his client base included some of the most influential people in the world. To the outside world, he projected the appearance of confidence, trustworthiness and competence. 

But it was all a mirage. Behind the facade, Madoff was running what became the largest Ponzi scheme in history, an elaborate financial lie that unraveled in the wake of the 2008 financial crisis. When the smoke cleared, it was revealed he’d robbed thousands of investors of an estimated $65 billion. 

Bernie Madoff’s Early Career

Born in 1938 in Queens, N.Y., Madoff came from a working-class family. As a teen and during college, he worked a series of jobs to help fund a brokerage firm, Bernard L. Madoff Investment Securities, which opened in 1960. He served as chairman of NASDAQ for three one-year terms in the 1990s.

But while the brokerage firm that served as the public face of Madoff’s business operated legally for decades, his private investment advisory business, kept mostly hidden, was not. Like other brokerage firms, Madoff’s was subject to the whims of the stock market’s performance. But Madoff's private investment funds posted annual returns of 10-12% profits, regardless of market conditions. That kind of consistency was highly unusual. Most funds average 7–10% annually, and even top performers experience market-related ups and downs. Madoff’s claimed returns, delivered smoothly every year, simply didn’t match historic market performances.

He explained the fund’s impressive performance as the result of what he called a “split-strike conversion” strategy. Few clients understood how the method worked, but even those who might have questioned his methods didn’t want to rock the boat.

Inside the Fraud

Madoff’s operation functioned like a classic Ponzi scheme. Early investors were paid with money from newer investors. There were no actual profits. Instead, he fabricated phony account statements to show gains that didn’t exist. His success relied entirely on a continuous flow of new money.

Madoff’s main weapon was trust and his facade of cool competence. He cultivated exclusivity, and investors sometimes had to beg to be allowed to invest with his fund. His investors ran the gamut, from friends and family members to retirees who trusted him with their life savings. The fund boasted charities, pension and hedge funds, banks and even celebrities like Kevin Bacon, Kyra Sedgwick and Steven Spielberg. The foundation of Holocaust survivor Elie Wiesel invested much of its funding with Madoff as well.

Others in the financial industry grew skeptical of Madoff’s unusual success, including analyst Harry Markopolos. As early as 1999, Markopolos had approached the Securities and Exchange Commission, the government agency responsible for regulating financial markets, with his concerns. But despite repeated attempts to present evidence of Markoplos’s claims, the SEC largely ignored them. Madoff’s firm managed to pass its five audits in two years thanks to fake documents and a bit of good fortune. 

The Collapse

In late 2008, a global financial crisis was underway, triggered by the collapse of the U.S. housing market and risky lending practices. With bank failures and stock market crashes following, many feared economic collapse and Madoff’s investors rushed to withdraw billions from the fund.

His house of cards quickly fell apart.

Madoff, who’d lived a lavish lifestyle that included multiple luxury homes around the world, a private jet and expensive artwork, didn’t have the cash to pay the mass redemptions. On December 10, 2008, Madoff confessed the truth to his sons Mark and Andrew, who worked at his firm, after they questioned where he got the money for early holiday bonuses as the market was falling apart. Shocked and devastated, they reported him to federal authorities. When Madoff was arrested the following day, he admitted to running the Ponzi scheme for decades. 

The Madoff Aftermath

In March 2009, Madoff pled guilty to 11 felonies, including securities fraud, wire fraud and money laundering. He infuriated many with his seeming lack of contrition or remorse for his crimes, and in June 2009, he received the maximum allowable sentence: 150 years in federal prison. Thousands of Madoff’s victims lost homes and their life savings. Efforts to recover stolen funds led to the return of more than $14 billion to defrauded investors.

Madoff’s family was also devastated by the patriarch’s massive criminal enterprise. While his wife Ruth Madoff was never formally charged, many believed she must have been involved in the scheme, and she later agreed to a settlement with prosecutors to surrender most of the couple’s assets. His son Mark died by suicide in 2010, the second anniversary of Madoff’s arrest, and his other son Andrew died of cancer in 2014. Bernie was sent to a federal prison in North Carolina until he died of natural causes on April 14, 2021, at age 82.
