"Big Short" Bill Ackman's latest bet revealed: aggressively shorting over $1 billion on Nvidia and Palantir.

The recently released 13F filing shows that the fund under Berkshire has shorted NVIDIA for $186 million (notional value) and shorted Palantir for $912 million. This guy made $725 million by shorting the housing market in 2007, and now he's targeting AI concept stocks.

What is his logic? History repeats itself:

1️⃣ AI Bubble Warning Signs - 30 years ago, before the internet bubble burst, the P/S ratios of those internet companies were around 30-40 times. Now Nvidia has surpassed 30 times, and Palantir is outrageous at 152 times. Is this data outrageous?

2️⃣ Technical Hype Cycle - Internet, gene sequencing, nanotechnology, blockchain... every time the "next big event" is first hyped up and then bursts. This wave of AI is unlikely to be an exception.

3️⃣ Valuation corrections will eventually come - even if it temporarily holds up due to the Federal Reserve's rate cuts and high growth, the P/S ceiling has never historically been broken in the long term.

To be honest, this shorting may be poorly timed (it could still rise in the short term), but historically speaking, the probability of Boli betting right this time is quite high.
