The price of each share directly corresponds to the implied probability of that outcome occurring. As more traders participate and express their views, the price fluctuates, reflecting the collective prediction. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price movements are driven by supply and demand – if more people believe an outcome is likely, they’ll buy shares, driving up the price, and vice versa.
