PGA Tour: 3M Open Top 20

Platform comparison

Market context

The 2026 3M Open at TPC Twin Cities is the real-world event behind this contract, and a top-20 finish market is usually much less volatile than an outright-winner market because a strong four-round profile can cash even without contending on Sunday. That matters when reading the current **42% YES** crowd price: it is broadly consistent with a player who is viewed as having a meaningful chance to survive the cut and post a mid-pack finish, but it is not pricing in a dominant favourite’s level of edge. By comparison, pre-tournament sportsbooks are still centred on the usual win market names, with Scheffler listed around +275 outright and several other established PGA Tour players clustered well behind him, suggesting that trader attention is focused on finishing position rather than only victory probability.[1][2][6]

Historical 3M Open fields also point to a tournament where top-20 outcomes can be compressed by scoring conditions and weekend variance. The event has a full 144-player field, the top 65 and ties make the cut, and it awards 500 FedExCup points to the winner, which tends to attract a deep but not especially top-heavy entry list.[7] On prediction markets, the live Polymarket board shows a wide range of player-specific top-20 probabilities, with the front of the board materially above the 42% contract price for other runners, which implies analysts and market-makers see clear separation between the likelier and less-likely names in this prop.[3]

For traders, the main catalysts are the final field, any late withdrawals, and how the opening two rounds set up cutline risk, because top-20 tickets are sensitive to both participation and weekend access. Recent preview coverage has already highlighted that prices can move sharply if Scottie Scheffler or another leading name withdraws before Thursday’s first round, while the field and odds are still being updated into the eve of play.[1][6] The contract also resolves on the official PGA Tour results, so any weather delay, score correction, or administrative delay that pushes final standings beyond the stated deadline becomes relevant to settlement risk rather than just on-course probability.[7]

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
