Prediction markets on death are an assassination market. That's why they're against the rules even on Polymarket and Kalshi.

Prediction markets on terrorist attacks and wars are one step back from that, but similar negative side effects are possible. And, regardless of what people are betting on, the corruption incentive appears where it did not previously, resulting in things like this.

(I don't think there's literally an Iranian missile operator opening Polymarket, taking out a position for "missile lands on Israel", and then pressing the launch button, but ultimately that's what uncensored markets with uncensored movement of money would enable)

1. It's not something I don't like, it's something plain illegal in most of the world, including the US under the Dodd-Frank act, which the current executive has decided to not enforce.

2. The reason it is illegal it is beyond obvious: basic economics and game theory explain you how dangerous it is tying real world events with financial incentives.

Why is everything you like protected from being banned?

This is an argument against all laws, which probably deserves more than a couple sentences.

Why do you apparently like a system that lets people bet on atrocities and then take steps to make said atrocities more likely?
