PGA Tour: 3M Open Top 20

Platform comparison

Market context

The 3M Open is under way at TPC Twin Cities in Blaine, with a 144-player field and an 8.8 million dollar purse on a par-71 layout measuring 7,431 yards.[1][5] The market’s 42% yes price implies the contract is being treated as a live but far from assured top-20 finish, which is broadly consistent with a mid-pack PGA Tour proposition rather than a near-lock. In practical terms, that sits well below the kind of pricing usually associated with a genuine contender, and closer to the range where one strong or weak round can swing the outcome materially.[1][2]

For comparison, the main historical anchor is course and field context rather than a direct repeat of this exact contract: TPC Twin Cities tends to reward birdie-making in a standard 72-hole stroke-play format, but even elite names can still miss the top 20 if scoring becomes compressed.[1][2] This week’s field includes eight of the world’s top 50, headed by Scottie Scheffler, while defending champion Kurt Kitayama is also back, so the implied probability on any single player should be judged against a stronger-than-average leader board.[1] If sportsbook lines are materially shorter than 42%, the market may be leaning too optimistically; if they are longer, the exchange is pricing in a better chance than the book.

The main catalysts are straightforward: tee-time draw, early scoring relative to the field, and any injury or withdrawal news before the first round and over the weekend.[1][5] Because the event runs from 23 to 26 July and the contract settles on official PGA Tour results, traders should watch for any change to the field and for who stays inside the top-20 bubble after moving days, especially in a tournament where a low-scoring leaderboard can tighten quickly.[5]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets UK, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
