I give permission to anyone to make bets on my human life, I don’t mind at all :-)
It never made an iota of economic sense -- if insurance underwriters are on the wrong end of that deal, they aren't doing their jobs very well -- but a number of large corporations would do it, and gleefully pocket the payouts when rank and file employees died.
A sufficiently liquid prediction market on a human life is indistinguishable from a bounty. That’s exactly why you can only take out life insurance if you have some reasonable financial stake in somebody staying alive and not the opposite.
