On Polymarket, this market is priced through a continuous auction mechanism. Traders buy and sell shares representing their belief in each outcome – in this case, either Janae Preston or Polina Skliar winning the match. The price of these shares fluctuates based on supply and demand, effectively creating a probability estimate. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The higher the demand for shares in a particular player, the higher the price, and the greater the implied probability of that player winning. This dynamic pricing reflects the collective intelligence of the traders participating in the market.

Any news regarding player injuries, changes in playing conditions, or updated rankings could shift trader sentiment.
