All of these "politican out" markets will resolve to true if the politician dies: https://polymarket.com/predictions/out.

The language is usually "This market will resolve to “Yes” if <politician> ceases to be <Prime Minister/President/whatever>".

Or for another example: https://polymarket.com/event/will-neymar-play-in-the-2026-fi.... Will Neymar play in the world cup? Not if he's dead. Any kind of "will celebrity appear in X in the future" can be reduced to an assassination market.

Kalshi supposedly does not pay out if a death is involved

Not sure if Polymarket does the same. Also not sure if I really trust these people to be the arbiter of morality and adhere to their own rules when it doesn't benefit them.

I can't find any evidence that Polymarket has a rule like this, and they have paid out for assassinations in the past: https://polymarket.com/event/khamenei-out-as-supreme-leader-...

Yeah, Kalshi can't pay. 17 CFR § 40.11

> A registered entity shall not list for trading or accept for clearing on or through the registered entity any of the following:

> (1) An agreement, contract, transaction, or swap based upon an excluded commodity, as defined in Section 1a(19)(iv) of the Act, that *involves*, relates to, or references terrorism, *assassination*, war, gaming, or an activity that is unlawful under any State or Federal law.

Polymarket doesn't seem to care too much.

Polymarket is now two separate entities. Last year they were banned from the US and stopped taking on new US customers and made their site withdrawal only for anyone based in the US. You could bypass it with a VPN, but they did enough to at least look like they were complying.

They've now created a separate company that I believe is called Polymarket US which has it's own version of the site/app which they are using to re-enter the US market. This switched from invite only beta to open sign ups a few months ago.

Polymarket US is mainly just sports betting with a small number of crypto, commodities, and political election based markets, although they have said they plan to expand their market options. Their US based site almost certainly doesn't violate those rules. The version that is used outside the US is the one that has markets that violate that, but since they're not in the US, there's not much that can be done.

So if you kidnap them, hold them in a bunker for a month, then release them, it will pay out. That's probably a positive thing for the world somehow, right?

I can't see how that can ever backfire /s

Sure but so does any political betting.
