Well, if I had bet a large sum of money on the pound tanking in the near future, I would have an excellent reason for wanting a no-deal Brexit. Of course I'd be an utterly appalling sociopath for wanting to enrich myself at the expense of an entire nation, but then again if I'm a sociopath that probably won't bother me.
Short selling the Pound and then manipulating it through major sociopolitical change is a fairly complex and involved way of achieving something you can almost as easily achieve by short-selling a failing large business, though.
(Personally I think short-selling is evil and needs to be banned - betting on failure is not how things should work - in the stock market one should bet on and invest in success)
