On April 13, renowned short-seller and founder of Muddy Waters, Carson Block, issued a startling warning: as AI disrupts the market, bets against the U.S. stock market will be "smooth sailing." Carson Block stated that AI could trigger a market shock greater than the 2008-2009 global financial crisis. For those short-sellers who have endured years of "hard times" in the U.S. stock market, this undoubtedly opens the door to profit once again. Block noted that with the rapid proliferation of AI, the economy and markets will face profound impacts in the coming years, as turmoil in the job market will inevitably affect government finances and financial stability. "In the medium to long term, there will be severe economic and market consequences, as well as financial issues for governments, which I believe will make the global financial crisis seem trivial in comparison." He added, "As a short-seller, this will be an excellent opportunity to thrive," comparing it to the substantial profits earned by short-sellers who bet on the market crash in 2008. In recent years, many prominent short-sellers have retreated and closed their firms, including Jim Chanos, who shorted Enron before its collapse in 2001, and Nathan Anderson of Hindenburg Research. Block's prediction signifies that after years of struggle, U.S. stock short-sellers may be on the verge of a turnaround.
