Market context
PGA Tour: FedEx St. Jude Championship Winner — current market-implied probability: 63%. This market will resolve according to the listed player who wins the 2026 FedEx St. Jude Championship tournament. If a listed player is eliminated from contention for the FedEx St. Jude Championship …
Methodology
This page compares PGA Tour: FedEx St. Jude Championship Winner specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. The live probability is the Polymarket mid; the comparison columns summarise each venue's fee structure, KYC, settlement currency and payment rails. Every CTA routes to Polymarket Alternative, which mirrors the Polymarket order book at 0% fees.
Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
