On Polymarket, this market reflects trader sentiment rather than traditional sportsbook lines. Prediction market odds often diverge from sportsbook odds due to different participant dynamics and information availability. Traders on Polymarket may price in nuances or early signals not fully captured by sportsbooks, leading to variations in implied probabilities. The volume of $37,165 shows strong engagement, but these odds should be viewed as a separate analytical tool rather than a direct comparison to sportsbook lines. Sportsbook odds incorporate different risk models and market maker adjustments, which can cause consistent differences in pricing.

The final determination will match the officially recorded winner or draw, closing all positions based on the confirmed match result.
