How do you defend these slimey companies? They’re actively running a mob casino and you still have people acting like government is the bad guys here. That doesn’t mean there can’t be better regulation of other markets, but comparing prediction markets to stock markets is a huge stretch.
It's not a casino. You aren't betting against the house with polymarket, unlike with gambling sites. You're betting against other players.
Disagree, I find their product valuable and use them daily as a source of unusually high quality predictions. When used for this purpose insider trading is a feature that improves the quality of predictions. I see some fraud as in any market, but the overwhelming majority of transactions are voluntary, open and relatively informed within a highly transparent system.
I think that self fulfilling prophecy attempts by deep pockets trying to sway markets by bucking trends generally transfers money from more to less foolish bettors.
