On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell shares representing their belief in the likelihood of each outcome. The price of a share directly corresponds to the implied probability of that outcome occurring. As more traders participate, the market price adjusts to reflect the collective assessment. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price movement is driven by supply and demand; if more traders believe Dellien/Roncadelli will win, the price of shares representing that outcome will increase, and vice versa. This dynamic pricing ensures the market remains responsive to new information and evolving sentiment.
