PGA Tour: Wyndham Championship Winner

Platform comparison

Market context

The Wyndham Championship is being played at Sedgefield Country Club in Greensboro, with a 144-player field and a regular-season finish that feeds directly into FedExCup positioning.[1][5][6] A 0% crowd-implied probability on a named winner is consistent with an open market only if no golfer has materially separated from the field yet; on platforms such as Polymarket the contract price is shown as implied probability, while Betfair and Smarkets present decimal odds that can move more slowly when liquidity is thin, and KYC access is generally broader on regulated exchanges than on crypto-native venues.

Historically, this event can produce volatile pricing because the field is strong but not as top-heavy as a major, and late withdrawals have already changed the entrant list several times this week, including Patrick Cantlay, Daniel Berger, Garrick Higgo, Taylor Moore, and Si Woo Kim.[2][3][4] That matters for market reading because a withdrawal or official elimination can force an immediate “No” on a listed player under the rules here, while an unlisted champion would settle as “Other”; by contrast, exchanges such as Betfair or Smarkets usually let traders express the same view by laying or backing at decimal prices, with fees reducing realised edge more visibly than a raw probability quote.

The main catalysts are scoreboard position, weekend cut dynamics, and final-round tee-time timing, plus any late medical or weather-related withdrawals before the tournament ends.[5][15][16] The PGA Tour and tournament site have the field and schedule pinned down for 6-9 August, and the event is being broadcast across Golf Channel, CBS, and streaming services, so a trader can watch for leader-board shifts in real time rather than waiting for post-round updates.[4][5][6]

Methodology

This page compares PGA Tour: Wyndham 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.
