It's a world where renting a helicopter is hilariously cheap available to some average person.
Looking at my local tourist helicopter place, a private custom flight is $1k per ~15m. That seems like nothing if it allows you be make millions with the information.
You can’t make millions from shorts unless you’ve already got millions to risk.
Shorts don't cost much to open, just the borrow rate on the shares. As long as it goes straight down you can leverage quite a bit without getting called.
Of course, this is the fastest way to lose your shirt and everything you have ever worked for, if there is any uncertainty.
Yes, I'm sure Robinhood or Schwab will allow me to open a $2M short position when my portfolio is $[sufficiently small that I'm debating the costs of a couple of thousand for a helicopter charter].
It's easy enough to synthesize 100x leverage by synthesis through options. If you have $25k for a margin account you could do it no problem. Of course, your funds would be rapidly vaporized if you were even a little bit wrong on timing or you needed more margin for volatility to keep it from getting called before it dips.
