Typically, prediction market odds reflect a wisdom-of-the-crowd perspective, often differing from initial sportsbook lines. Sportsbooks set odds based on their internal models and aim to balance action on both sides, while this market aggregates the beliefs of many individual traders. If a significant amount of money is wagered on one outcome, the odds will shift accordingly, potentially revealing information not yet fully priced into traditional sportsbook offerings. It's common to see prediction markets move faster than sportsbooks in response to new information or changing sentiment.
On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell shares representing their belief in the outcome. The price of a share directly corresponds to the probability of that outcome occurring. As more traders participate and express their views, the price adjusts to reflect the collective assessment. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market’s price is determined solely by supply and demand among traders on Polymarket, and isn’t influenced by external factors or a central authority setting the odds.
This market resolves around Oct 23, 2026, with the outcome confirmed once the event is verifiable from credible public reporting.

Traders holding shares in the winning outcome will be entitled to a payout based on the final market price at resolution.
