On Polymarket, this market is priced through a continuous auction mechanism, where traders buy and sell shares representing their belief in the outcome. The price of a share directly reflects the implied probability of that outcome occurring. As more traders participate, the price adjusts to reflect the collective assessment of the event. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market’s price is determined solely by supply and demand within Polymarket, and is not influenced by external factors or other prediction venues. This creates a dynamic and responsive pricing system.
