Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks set their lines based on internal models and aim to balance action on both sides, while this market allows traders to express their own beliefs about the probability of each outcome. If a significant number of traders believe Kato/Wu are more likely to win than sportsbooks suggest, the odds on Polymarket will shift accordingly. It’s common to see discrepancies, especially before major events, as new information emerges and public opinion evolves.
On Polymarket, this market is priced through a continuous auction mechanism.
