He's not shorting this time. He has put options. This is a "short position" i.e. one that behaves inversely to the stock price, but his downside is limited (at the expense that he pays the full downside up front, and can lose money even if the stock goes down, if it doesn't go down by enough).
TFA says the options are on "roughly 1 million NVDA shares worth $187 million", implying NVDA was around $187 at the time of acquisition. That more or less tracks with the September 26 close, and this was apparently disclosed in a September 30 filing. NVDA is currently above $200. Similarly, he would have options on PLTR bought when that was also somewhere around $182 (roughly matching the September 30 close); even with today's crash, the stock is hovering around $190 as I write this.
So depending on the duration of the options there's a pretty decent chance he's going to lose money, and depending on the strike price it might well be the entire premium. As far as I can tell, neither of these is disclosed in the filing.
