He bought 8001 put options on some undisclosed date at an undisclosed strike date and price. You can take a look at the options chain for TSLA to get an idea. For example, a $450 put for September 17th 2021 would cost about $16.70 per share: https://finance.yahoo.com/quote/TSLA/options?strike=450&straddle=true https://finance.yahoo.com/quote/TSLA/options?strike=450&stra... One option counts for 100 shares, so that would be a (8001 * 16.70 * 100) 13.36 million dollar bet. Suppose that TSLA is worth only $400 on that date, with your right to sell at $450 you'd be in the money for 40 million dollars, or roughly $26 million in profits. If TSLA is worth $450 or more on that date, your options expire worthless.
