Michael Burry discovers that the US housing market is on the verge of collapse in the early 2000s due to risky subprime mortgages being bundled into bonds. He buys credit default swaps to bet that the mortgage-backed securities will fail. Others like Greg Lippmann, Steve Eisman of FrontPoint Partners, and Charles Ledley and Jamie Mai of Cornwall Capital also buy swaps. In 2007, the housing bubble bursts as subprime mortgages default, causing major financial firms to collapse until the US government intervenes with a bailout.
