Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks set lines based on their own models and aim to profit by balancing action on both sides, whereas this market allows anyone to express their belief about the outcome. Often, prediction markets are more accurate than traditional forecasts, especially when there's significant public interest. However, sportsbook odds are readily available and provide a useful benchmark for comparison, and may offer different value depending on your own assessment of the game.
On Opinion, this market is priced through a continuous auction mechanism where traders buy and sell contracts representing different outcomes. The price of each contract reflects the collective belief of the traders about the probability of that outcome occurring. On Opinion, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The current price indicates what traders are willing to pay for a share of the potential payout if their predicted outcome comes to pass. As more trades occur, the price adjusts to reflect new information and changing sentiment surrounding the Mariners-Rockies game.
