Can you bet on elections in Vegas? I didn’t think they laid odds for elections there.
You can bet on ANYTHING in Vegas.
Winning shares are paid out after the election. Right now, you can get a share of Donald Trump to win the White House (which will pay $1.00 if he actually does win), for $0.097. That's less than a dime, so > 10-to-1 payout.
If he loses you lose your the money paid for all your shares.
