The outcomes listed above show how traders are pricing this question. Venue prices are not currently available on this page. Each price reflects the market’s implied probability, not a guaranteed result. This event is archived; prices shown are historical.
No historical prices are available on this page. The last available price is not necessarily the final settlement price.
Venues have different traders, liquidity and fees, so their prices can differ. A cross-platform comparison needs available prices for the same outcome on at least two venues.
For example, a 40¢ price implies about a 40% chance. For a standard $1 contract, a share pays $1 if its outcome settles as correct and $0 if it settles as incorrect. A winning share bought at 40¢ earns 60¢ before fees. Check each venue’s settlement rules, fees and eligibility before trading. Historical prices alone do not identify the winning outcome.
