I’m sort of confused on what prediction markets are going for? Polymarket here said they referred this to the DoJ and are trying to catch users using such insider info, but trading on insider info is the whole point of these markets is it not? They bill themselves as providing accurate predictions, but the accuracy of those predictions is predicated on incentivizing (financially) users with non public info to share it. They should probably pick a lane- is it gambling or is it incentivized insider trading for public good (accurate predictions)?
