Pronóstico: PGA Tour: The Open Championship Winner

Platform comparison

Market context

Scottie Scheffler holds the Claret Jug after his 2025 triumph, making him the +700 favourite for the 2026 Open Championship at Royal Portrush, while Rory McIlroy sits second at +850 [1][2]. The Polymarket contract for a specific listed player currently trades at 11% YES, implying a modest but non-trivial chance of victory against the field. On Polygon, this position settles in USDC via conditional tokens, where elimination from the tournament triggers an immediate "No" resolution, and an unlisted winner forces an "Other" outcome.

Historically, defending champions in major golf tournaments face steep odds of repeating, with only a handful securing back-to-back Claret Jugs in the last century. The 11% price reflects this structural difficulty, aligning with comparable cases where favourites outside the top two struggled to convert odds into wins. Traders reading this probability should note that bookmakers list Scheffler at 4/1 and McIlroy at 13/2, suggesting the market may be underpricing the top tier relative to the broader field [2].

Key catalysts include the final confirmed field list and any injury updates from the PGA Tour ahead of the July start. Scheffler’s schedule and McIlroy’s recent form will dictate short-term price swings, while weather forecasts for Royal Portrush could alter contention dynamics. Recent odds confirm Scheffler as the primary favourite, with Englishmen Tommy Fleetwood and Matt Fitzpatrick trailing at +1500, offering potential value if the market overreacts to early practice round performances [1].
