More to your point... I don't think economic theory has anything to do with it. I'm a capitalist and I think that "prediction markets" is just an idiotic rebranding of "legalized gambling" and generally speaking, gambling more than a token sum (say, less than $100) should not be legal exactly because any benefits of gambling is far outweighed by the mountains of externalities it brings. Yes, this includes the obvious incentives to threaten random people. It's bad for society, so it should be effectively banned. The only reason why it has suddenly become legal everywhere in the US is because many states have found themselves under mountains of deferred liabilities and are scrambling to raise revenues however they can without raising taxes. It's shameful.
