Both sports betting and prediction markets are effectively the same as reading tea leaves anyway. You can determine the real odds in roulette or blackjack because those are closed games that have simple probabilities, but any odds given in sports betting or prediction markets are just fancy guesses
The odds in betting are the payout ratio. To hinder manipulation, the payout ratio would have to be hidden and then the platform can just always say you won less money than you did.
