PGA Tour: The Open Championship Winner

Platform comparison

Market context

Scottie Scheffler is the current favourite to win the 2026 Open Championship, holding +700 odds as bookmakers expect him to defend the Claret Jug he secured in 2025[1][2]. On Polymarket, the contract for this specific player sits at an 11% implied probability, priced in USDC on the Polygon network using conditional tokens that resolve instantly upon elimination or victory. This on-chain price reflects a market that views the 4/1 betting line as generous, suggesting traders are hedging against the volatility inherent in major golf tournaments where form can shift rapidly between rounds.

Historically, 11% probabilities for a top-four favourite in a major often precede significant price swings when the tournament begins, as seen in previous Open Championships where favourites like Scheffler or McIlroy faced early weather delays or course-specific struggles[1]. Comparable cases show that when a player holds such a distinct advantage in traditional odds yet trades at a lower implied probability on prediction markets, it frequently indicates a lack of liquidity or a specific fear of an unlisted "Other" winner, a common outcome in golf when long-shots break through.

Traders should monitor Scheffler’s official schedule and any injury updates leading into the event, as his status as the World No. 1 makes him the primary catalyst for price movement[2]. Key dependencies include the final field confirmation and tee-time announcements, which often trigger immediate liquidity shifts on the chain. Recent coverage confirms Scheffler’s dominance and McIlroy’s position as the second favourite at 13/2, meaning any news affecting either player’s participation will directly impact the 11% YES price before the settlement window closes in July 2026[1][2].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
