Icahn's $9 Billion Bet Against America Backfires.

Billionaire investor Carl Icahn lost almost $9 billion after betting against the US economy and the stock market, according to an analysis by the Financial Times. Icahn began betting on a market collapse in the aftermath of the 2008 financial crisis, and became increasingly aggressive in later years. His investment portfolio has lost money every year since 2014, largely because of his increasingly bearish positions. Icahn Enterprises' shares are down 37% this month due to a report by short-seller Hindenburg Research, which alleged the company employs a "ponzi-like" financial structure.
