>Is this short ratio atypical?

I wouldn't say so. There are other heavily shorted stocks that have a much higher short ratio because of their small float (e.g. MTCH).

>but is there a good way to determine who?

Short sellers don't have to disclose their positions, unlike investors who're long the stock. You can try to get a better sense of who's thinking what through headlines and analyst notes/reports.

Side note: Elon tweeted out that we'd see the 'burn of the century' (a short squeeze) and that it would be bigger than the VW/Porsche squeeze in 08.

Thanks, for replying when I couldn't! Generally I agree with you. I would disagree that this level of short interest is typical, I think 20%+ short interest is high 90s percentile territory. The relatively low short ratio is more indicative of how highly traded TSLA is (short ratio = short interest / avg daily volume).

If there's a way to report who is short a stock, I don't know it. There are also other trades to profit from decreases in an underlying security (buying puts, selling calls) and I don't know about reporting obligations there, either.
