I bet $100k that Marcus Badperson will die on the morning of 15 June 2013"; best way to collect is to do the deed yourself (or subcontract.) But don't you need someone else to take the other side of the bet? You can't just bet X and get more. You can only get what Y bets in opposition. Assuming no one else agrees with you and makes the same bet, because then you'd have to share what Y put down. And who's going to be the opposing side in these bets? I happen to know Marcus Badperson is a janitor for the federal serve and will spend all day on June 15th cleaning the gold bars inside the safest safe in the world. So I bet a billion dollars he does NOT die between the hours of 9am and 5pm on June 15th. Unless someone else bets more than a billion, the best I can do is simply collect the same billion I put down. I was hoping to find an elaboration of who could be the counter party in the Wikipedia page, but nope nothing there. I think the assassination market is very probable if you completely skip the question of who's the counter party. Or if you have no idea how betting and payouts work in the first place. Otherwise this "assassination market" is total bullshit.
