Sportsbooks set odds to balance liability and extract a margin, while prediction markets like this one are driven by trader consensus on actual probability. This market aggregates the beliefs of many independent participants without a built-in house edge, potentially offering a purer signal of true likelihood. However, sportsbooks may incorporate sharper professional action and real-time injury or weather data, so neither source is universally more accurate.
