PGA Tour: FedEx St. Jude Championship Winner

Platform comparison

Market context

The 2026 FedEx St. Jude Championship will take place in August at TPC Southwind in Memphis, Tennessee, as the opening event of the PGA Tour's FedEx Cup playoffs. The tournament attracts the Tour's top 125 players by season-long points standing, making it a high-calibre field where form and recent momentum carry substantial weight. The 6% implied probability reflects a specific player listed in this market's roster, meaning the odds account for field strength and individual recent performance rather than a generic "any player" scenario.

Historical context shows FedEx St. Jude winners typically emerge from the top 30 in world rankings, though the playoff format occasionally rewards players riding hot streaks. Comparing across platforms reveals structural differences: Polymarket displays decimal odds (roughly 16.67 for a 6% probability), whilst Kalshi and Betfair present fractional or decimal formats with varying fee structures—Kalshi charges flat 2% on both sides, Betfair takes commission on net winnings, and Smarkets applies a 4% commission. These fee differences materially affect breakeven thresholds, particularly on lower-probability outcomes where transaction costs compound.

Traders should monitor PGA Tour injury reports and course-fit analysis through June and July 2026, as late withdrawals or form changes can shift individual probabilities substantially. The settlement window closes 16 August 2026, aligning with tournament conclusion. Notably, if the listed player misses the cut or withdraws, this market resolves immediately to "No" rather than remaining open—a rule distinction that separates this contract from broader "winner" markets on other platforms.

Methodology

We read PGA Tour: FedEx St. Jude Championship Winner from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

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.

Is Betfair a Polymarket alternative?

Only partially. Betfair Exchange is UK-focused with a sports-betting emphasis; they have politics markets but with thinner liquidity than Polymarket. Settlement in GBP/EUR, 2-5% commission on winnings.
