Short seller allegations cause Carl Icahn's fortune to plummet $10 billion.

Carl Icahn's wealth dropped by $10 billion after Hindenburg Research, a short-seller, released a report alleging "Ponzi-like" economic structures at Icahn Enterprises. The report claimed that the holding company used inflated asset valuations and "Ponzi-like" economic structures. Icahn's fortune was hit by the rout, and he is now worth $14.6 billion, 41% of his net worth on Monday. Icahn Enterprises responded to the allegations, saying the report is "self-serving" and "intended solely to generate profits on Hindenburg's short position at the expense of IEP's long-term unitholders."
