Who will win the 1st round 3-ball: Thompson/Campbell/Homa?

Prediction market odds and sportsbook odds often diverge because they reflect different pricing mechanisms and trader bases. Sportsbooks set lines to balance action and manage risk, while prediction markets aggregate the collective beliefs of traders wagering real money on outcomes. This market may show materially different odds than traditional sportsbooks, particularly as new information emerges or as event time approaches. Comparing the two can reveal where professional traders and casual bettors disagree on the likely result.
