> How long before there’s a bomb threat at Pfizer to make a short part off big? Fair point, but the anonymity of the markets mentioned in the post matters here. You can short a stock or buy put options, but if the SEC gets suspicious they can trace them back to you (and there are occasional stories of this happening, like the guy who set off actual bombs at Target). With anonymous prediction markets, they would have a harder time figuring out who stood to benefit.
