How much did Bernie Madoff steal? The exact amount that Bernie Madoff stole is difficult to determine, as his Ponzi scheme lasted for more than two decades and involved many complex financial transactions. However, it is estimated that Madoff’s fraud involved a total of approximately $65 billion, including the money that he stole from investors and the false profits that he claimed to have made on their behalf. This makes it one of the largest financial frauds in history. At the time of his arrest in December 2008, Madoff had reported that his investment firm held approximately $65 billion in assets under management, but in reality, most of this money had already been spent or lost in failed investments.
