On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell shares representing their belief in each outcome. The price of a share directly corresponds to the probability of that outcome occurring, as perceived by the market participants. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders buy shares in a particular player, the price of those shares increases, and the implied probability of that player winning rises. Conversely, selling shares decreases the price and lowers the implied probability. This dynamic pricing ensures that the market odds constantly reflect the collective intelligence of the traders.

The platform will verify the result against reliable sources to ensure accuracy and transparency, finalizing the market and distributing payouts to those who correctly predicted the winner.
