I know very little about markets, but: aren't the short-sellers just going to provide liquidity for the big index funds? Like, if the funds HAVE to buy SpaceX, and the funds are enormous, wont every single stock sold short be immediately gobbled up, as well as pretty much anyone else wanting to sell? Even if everyone else is selling like mad, it wont affect price much at all?

Maybe this is naive, but if these enormous funds are more or less forced to buy SpaceX, it seems impossible that "actual price discovery" is going to happen in any reasonable amount of time, and the short-sellers will be screwed.
