> I see no problem with betting on who will win a sports match...

I do wonder - what if the sports teams or politician loses intentionally; which could either be to profit off the loss or due to threats from an actor who seeks to profit?

I heard that Kalshi paid out for when Khamenei was killed in Iran (the bet was for when he would go out of power), so murdering people could be another way to win such a bet on who will lose. Even injuring a sports player could easily change a game result. With so much money on the line, it doesn't seem like a good mix.
