Description

This market focuses on identifying which driver achieves the greatest improvement in race position from start to finish at a specific IndyCar event. The outcome depends entirely on each driver's official starting and finishing positions, reflecting their performance gains during the race.

Kalshi

The market resolves based on which driver records the largest positive difference between their starting grid position and finishing position in the main race. All drivers must have both an official starting grid and a classified finishing position to qualify. If multiple drivers tie for the largest position gain, payouts are divided equally among 'Yes' positions, with 'No' positions receiving the complementary amount. Special rules handle tie scenarios in grid or finish positions, and pit-lane starters are assigned positions accordingly. Postponements within 48 hours keep the market active, while outright cancellations or reschedules beyond that window result in fair settlement of all contracts.
