NASCAR: Iowa Corn 350 Powered by Ethanol Winner

Resolution Criteria

This is a Polymarket on the winner of the 2026 NASCAR Cup Series Iowa Corn 350 Powered by Ethanol, scheduled for Aug 9, 2026. If the 2026 NASCAR Cup Series Iowa Corn 350 Powered by Ethanol is canceled or rescheduled to a date 7 days after the original scheduled date, this market will resolve to "Other." This market will resolve in favor of the driver who is officially listed in first place in the Official Race Results published by NASCAR following the conclusion of the race. The official results are typically released shortly after the race ends and include any applied penalties and official adjustments. Disqualifications or changes made after the publication of the official results will not affect market resolution. The timing of the victory lane ceremony does not determine the result for this market — only NASCAR's published results will be used to resolve this market. The resolution source will be the official NASCAR website (nascar.com) and a consensus of credible sports news reporting.
