alt Hacker NewsPrediction markets as a useful tool are predicated on insider information. The punters without edge are the bait incentivizing the insiders.
And in the US prediction markets are regulated like commodities which have much more lax insider rules, because again, insider trading is the point.

Why would we want insiders to profit on a public decision like war? If some general has money on Iran's leader being taken out by March 1, he might not be acting in the best interest of the country.
How is it useful when what we are seeing is insiders place massive bets immediately before the event resolves. Does gaining this information a few hours early provide value to society that offsets the impact of normalizing gambling and attaching incentives to bad outcomes of war, politics, etc.
This notion that price discovery is only possible with insider trading is demonstrably false yet somehow surprisingly pervasive.

And like any other gambling (see 1919 Black Sox), they can also incentivize behavior for actors who can influence the outcome of what’s being gambled upon.
Personally, that’s a significant enough negative externality for me to not want to live in a society where “prediction markets” are popular.
