Ok, thanks for the clarification. Makes sense, otherwise there'd be free money on the table with some of the current bets where betting on both outcomes at the same time would yield assured profits.
I should have guessed from this message on your main page:
Winners split the losers sats All bets on one outcome go into a pot. When the event occurs, the pot is split proportionally among the winning bets.
Maybe adding somewhere it's parimutuel betting could clarify things further.
