Maverick McNealy's probability of a top-10 finish surged 51 percentage points to 60%, marking the most significant individual contract move. This repricing directly reflects the market's pivot from pre-tournament speculation to in-play results after the first two rounds of competition. **Key Market Signals** - **Market Repricing:** Xander Schauffele's probability for a top-10 finish declined 38.0pp to 30%, reflecting underperformance in the initial tournament rounds. - **Consensus Rebalancing:** While 34 contracts rose against 33 that declined, total trading volume on declining contracts (390,804) substantially exceeded that of rising contracts (257,104), indicating a strong market consensus shift away from underperforming favorites. - **Performance Catalyst:** Live leaderboard standings after 36 holes were the primary driver, with players like Chris Gotterup and Hideki Matsuyama seeing probabilities rise +42.0pp and +34.0pp respectively, directly coinciding with their strong tournament positions. --- The prediction market for a top-10 finish at the 2026 PGA Championship saw a significant reshuffling on Friday, May 15, 2026, as traders reacted to the first two rounds of play at Aronimink Golf Club. Probability shifted dramatically away from several pre-tournament favorites who posted mediocre scores and toward players atop the live leaderboard. The most notable movement was for Maverick McNealy, who surged 51 percentage points to a 60% chance of a top-10 finish after securing a share of the lead at 4-under par [1, 9]. This repricing reflects a broad pivot from pre-tournament speculation to in-play performance. ## Distribution Analysis The market repricing was widespread, with 34 contracts rising against 33 that declined. The most significant gains were seen by players who performed well in the opening rounds, including McNealy (+51.0pp), Chris Gotterup (+42.0pp), and Ludvig Aberg (+38.0pp). Conversely, major probability drops occurred for high-profile players further down the leaderboard, such as Xander Schauffele (-38.0pp), Shane Lowry (-22.0pp), and Rickie Fowler (-17.0pp). | Outcome | Current Prob | Change | Volume | | :--- | :--- | :--- | :--- | | Scottie Scheffler | 75% | -8.0pp | 94,537 | | Maverick McNealy | 60% | **+51.0pp** | 11,762 | | Ludvig Aberg | 53% | **+38.0pp** | 3,181 | | Cameron Young | 53% | +30.0pp | 26,819 | | Chris Gotterup | 50% | **+42.0pp** | 13,162 | | Hideki Matsuyama | 50% | +34.0pp | 9,581 | | Alex Smalley | 50% | +18.0pp | 13,826 | | Min Woo Lee | 49% | +5.0pp | 13,513 | | Jon Rahm | 46% | +3.0pp | 9,540 | | Si Woo Kim | 40% | +27.0pp | 6,560 | | Justin Thomas | 39% | +13.0pp | 12,469 | | Patrick Cantlay | 37% | +5.0pp | 4,664 | | Rory McIlroy | 35% | +25.0pp | 21,461 | | Harris English | 34% | +15.0pp | 9,893 | | David Puig | 33% | +23.0pp | 3,107 | | Xander Schauffele | 30% | **-38.0pp** | 37,003 | | Max Greyserman | 30% | +15.0pp | 3,721 | | Kurt Kitayama | 27% | +23.0pp | 5,313 | | Stephan Jaeger | 27% | +20.0pp | 3,048 | | Aldrich Potgieter | 26% | +18.0pp | 9,033 | | Jason Day | 21% | +1.0pp | 11,594 | | Brooks Koepka | 21% | -14.0pp | 44,593 | | Jordan Spieth | 20% | -16.0pp | 33,939 | | Patrick Reed | 19% | -10.0pp | 16,158 | | Aaron Rai | 18% | +18.0pp | 1,495 | | Collin Morikawa | 16% | -15.0pp | 5,141 | | Rickie Fowler | 15% | **-17.0pp** | 9,094 | | ... (and 47 others) | | | | **Net: While the number of rising (34) and falling (33) contracts was nearly even, total volume on declining contracts (390,804) significantly outpaced that of rising ones (257,104), signaling a strong consensus shift away from underperforming favorites.** ## What's Driving the Shift The movement in the market aligns directly with the leaderboard standings as the tournament heads into the weekend. * **Strong Early Performance:** The primary catalyst is the live leaderboard after 36 holes of play. Maverick McNealy's 51-point gain is a direct reaction to his position as co-leader with a score of 4-under par [1]. Similarly, large probability increases for Chris Gotterup (+42.0pp) and Hideki Matsuyama (+34.0pp) coincide with their strong positions tied for third place at 3-under par [1, 9]. Cameron Young and Ludvig Aberg, both pre-tournament favorites, saw their chances rise after positioning themselves at 2-under par heading into the weekend [2]. * **Fading Pre-Tournament Favorites:** A significant amount of probability has moved away from established stars who struggled in the opening rounds. Xander Schauffele, whose chances fell 38 points to 30%, finished the second round at 1-over par [9]. Other major champions like Brooks Koepka (-14.0pp) and Jordan Spieth (-16.0pp) also ended Friday at 1-over par, well outside the top-10 positions they would need to secure a payout [9]. This represents traders selling off positions that were based on pre-tournament reputation in favor of current, on-course results. * **Cut-Line Survival:** The tournament cut was made at 4-over par, with 79 players advancing to the weekend rounds [6, 9]. Players who flirted with the cut line but survived, like Rory McIlroy, saw their probabilities increase (+25.0pp) as the risk of elimination passed, though they remain far from the lead [6]. Conversely, those who missed the cut saw their probabilities fall to near-zero. ## Market Context This market allows for multiple contracts to resolve as "Yes," as there will be ten players who finish in the top 10. The total implied probability across all 74 contracts is 1,234%, which reflects the market structure where the sum of probabilities is expected to approach 1,000% (10 winners x 100%), plus a market overround. The sharp repricing is a classic example of a market transitioning from *ex-ante* (before the event) probabilities to *in-play* odds. Initial prices were heavily influenced by season-long performance and historical success in majors. The current prices, however, are dominated by the realities of the first two rounds at the demanding Aronimink Golf Club course [5]. The high volume on declining favorites like Schauffele (37K) and Koepka (44K) suggests a high degree of conviction among traders that these players have left themselves too much ground to make up over the weekend. ## What to Watch The market will remain active as play continues through the weekend, with Round 3 scheduled for Saturday, May 16, and the Final Round on Sunday, May 17 [1]. Traders will be closely watching the "Moving Day" performance of the leaders to see if they can maintain their positions. The market is set to close on June 14, 2026, with settlement determined by the final official tournament leaderboard published by sources including the PGA Tour, ESPN, and Fox Sports. ## Related Analysis - [Read the complete market report for PGA Championship: Top 10 Finishers](/markets/sports/golf/pga-championship-top-10-finishers/) ### Relevant Answer Library - [Why do prediction market probabilities change so quickly after news events?](/answers/why-do-prediction-market-probabilities-change-so-quickly-after-news-events) - [How do fees and platform rules affect prediction market prices?](/answers/how-do-fees-and-platform-rules-affect-prediction-market-prices) - [How do I calculate expected value (EV) for a trade in a prediction market?](/answers/how-do-i-calculate-expected-value-for-a-trade-in-a-prediction-market) - [Browse all Answer Library topics](/answer-library)
