Muddy Waters’ Carson Block on How AI Could Unwind the S&P 500 | #640

from The Meb Faber Show - Better Investing · host The Idea Farm

My guest today is Carson Block, founder of Muddy Waters Research & Muddy Waters Capital and one of the last short sellers still standing. In today’s episode, Carson Block explains why he thinks AI could displace 15% of knowledge workers and unwind the market’s biggest stocks. He breaks down his short of SoFi’s aggressive loan accounting, why record-tight credit spreads worry him, and how he trades that risk with put spreads.  To close, Carson explains why he still calls China uninvestable and recounts his hardest battles.
