This market will resolve according to the driver who wins the 2026 NASCAR O'Reilly Auto Parts Series (Xfinity Series) championship. If at any point it becomes impossible for a listed driver to win the 2026 NASCAR O'Reilly Auto Parts Series (Xfinity Series) championship (e.g., they are mathematically eliminated from the playoffs), the corresponding market will resolve to "No". If the 2026 NASCAR O'Reilly Auto Parts Series (Xfinity Series) season is cancelled, postponed after November 21, 2026, 11:59 PM ET, or there is otherwise no champion crowned within that timeframe, this market will resolve to "Other". The primary resolution source will be official information from NASCAR (https://www.nascar.com); however, a consensus of credible reporting may also be used.
