Intro

This market tracks who will win the 2026 PGA Tour 3M Open tournament. The current aggregated consensus probability for Will Jackson Koivun to win is 100.0%, with Scottie Scheffler at 0.1%, drawn from Polymarket and Kalshi and resolving per the official PGA Tour website. Watch for the tournament conclusion on July 26, 2026, which will determine the official winner and settle all markets.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms use the official PGA Tour tournament results as the sole resolution source, with aligned treatment of ties and eliminations, though Polymarket includes an explicit Other outcome for unlisted winners while Kalshi's binary structure implicitly handles this through No resolution.Primary resolution logic: Official PGA Tour website (https://www.pgatour.com/)

Core resolution logic:

  • Market resolves to Yes/Winner if the named player wins the 2026 3M Open tournament according to official PGA Tour results
  • In case of a tie, the official PGA Tour tournament rules determine the single winner; if multiple winners are announced, the player whose last name comes first alphabetically is the winner (Polymarket rule, consistent with PGA Tour tiebreaker protocols)
  • If a listed player is eliminated from contention based on official tournament rules, the market resolves to No
  • If an unlisted player wins the tournament, Polymarket resolves to Other; Kalshi binary markets implicitly resolve to No for all listed players
  • All markets require resolution by August 1, 2026 at 8:00 PM ET; if no winner is announced by this deadline, Polymarket resolves to Other

Edge cases & clarifications:

  • Tie Resolution: If multiple players finish tied, the official PGA Tour rules apply. Polymarket specifies alphabetical ordering of last names as tiebreaker if multiple winners are announced.
  • Player Elimination: If a listed player is eliminated from contention based on official tournament rules (e.g., withdrawal, disqualification), the market resolves to No.
  • Unlisted Winner: If a player not listed on either platform wins the tournament, Polymarket resolves to Other; Kalshi binary markets resolve to No for all listed players.
  • Deadline Miss: If no official winner is announced by August 1, 2026 at 8:00 PM ET, Polymarket resolves to Other. Kalshi does not specify a deadline but implies resolution upon official announcement.
Timing: Resolution occurs upon official PGA Tour announcement of the 2026 3M Open winner. Polymarket enforces a hard deadline of August 1, 2026 at 8:00 PM ET, after which unresolved markets resolve to Other.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

This market will resolve according to the listed player who wins the 2026 3M Open tournament. If a listed player is eliminated from contention for the 3M Open tournament based on the official rules of the tournament, the relevant market will immediately resolve to "No". If an unlisted player wins the 3M Open tournament this market will resolve to "Other". In the event of a tie, this market will resolve according to the official winner as determined by PGA Tour official tournament rules. If multiple winners are announced then this market will resolve to the player whose listed last name comes first alphabetically. If no winner is announced by August 1, 2026 at 8:00PM ET this market will resolve to "Other". The primary resolution source will be the official results published by the PGA Tour website (https://www.pgatour.com/).

Kalshi

Tournament winner contracts resolve to Yes if the specified player wins the 3M Open. If a player forfeits, withdraws, or does not participate prior to teeing off, Tournament Winner and End of Round Leader markets resolve to No, while Finishing Position, Make the Cut, Head-to-Head, and 3-Ball markets resolve to Fair Market Value.

Frequently asked questions

The 3M Open winner market aggregates real-time odds across Polymarket and Kalshi, letting traders monitor consensus expectations for who will claim the PGA Tour event. Each platform displays its own pricing, volume, and leading contender, giving you a cross-venue view of how the prediction community is positioning ahead of the tournament. This market reflects live trader conviction as new information—player form, course conditions, injury reports—emerges. You can compare how different venues weight the same outcome, spot divergences between platforms, and track momentum shifts as the event approaches.

Prediction markets and sportsbooks price outcomes differently because they operate under distinct incentive structures. Sportsbooks set odds to balance their book and lock in profit margins; prediction markets reflect pure trader belief, since participants profit directly from accuracy rather than volume. Prediction markets often react faster to breaking news—injuries, weather, lineup changes—because traders have immediate financial skin in the game. Comparing the two can reveal where public sentiment diverges from professional oddsmakers, though both incorporate similar underlying data. Many traders use sportsbook lines as a benchmark while monitoring this market for edge opportunities.

Player injuries, withdrawals, or late-round form surges are primary catalysts. Course conditions—weather, greens speed, rough difficulty—can shift odds for players known to excel in specific setups. Recent tournament results and world ranking changes influence trader confidence in contenders. Betting syndicates or informed money entering either platform can trigger sharp moves. Media narratives around momentum, mental state, or equipment changes also sway sentiment. As the event date approaches, each round of practice or warm-up tournament results may trigger repricing. Monitor both platforms for volume spikes, which often signal informed traders positioning ahead of major developments.
