The price of each share directly corresponds to the implied probability of that outcome occurring. As more shares are traded, the price adjusts to reflect the collective belief of the participants. 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 isn’t influenced by external factors or other prediction markets.
