Insider trading is already illegal. What needs to be regulated is not markets, it is politicians. Once that is done, markets can peacefully continue the way they are.

Hard disagree. In the prediction market case, we're seeing many categories of people being incentivised to act on markets: soldiers, diplomats, staffers, journalists, businesses, sports and esports teams, as a quick, non-exhaustive list.

Do you think regulation of all possible categories of people who could behave adversely to influence prediction markets would be preferable to just regulating the market itself?
