Frequently Asked Questions
Indy 500 markets on PolyGram are binary contracts that pay $1.00 per YES share if the stated outcome occurs, and $0 if it does not. The price is the crowd's real-time probability, set by traders in the Polymarket order book — no house edge, no vig.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome after the event, a two-hour dispute window opens, and if no counter-claim is staked, USDC payouts clear to winning traders automatically.
