On Polymarket, this market is priced through a continuous auction mechanism. Traders buy and sell shares representing their belief in the likelihood of each outcome. As more shares are traded, the price adjusts to reflect the collective sentiment. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of a share directly corresponds to the implied probability of that outcome occurring. Higher demand for shares in a particular outcome drives up its price, increasing its implied probability, and vice versa. This dynamic pricing ensures that the market reflects the most up-to-date information available.
