Probabilities for players atop the leaderboard surged, with third-round leader Alex Smalley’s chances jumping to 59%. The gains for contenders like Smalley, Jon Rahm, and Rory McIlroy came largely at the expense of defending champion Scottie Scheffler, whose odds of a top finish fell sharply after a difficult day on the greens [1]. This major shift reflects the market consensus solidifying around the group of players in prime position to contend in the final round. Heading into Saturday, the tournament was described as "up for grabs" with a highly congested leaderboard [1]. The market has now clearly distinguished a set of favorites based on their 54-hole scores. The most significant move among top contenders was for Rory McIlroy, whose odds increased by 34.0 percentage points after he shot a 4-under 66 to move into contention [1]. Conversely, Scottie Scheffler, who is five strokes off the lead, saw his probability drop by 24.0 percentage points on the day's highest trading volume. ## Distribution Analysis The market shows a clear consolidation of probability among the handful of players at the top of the leaderboard heading into the final round. The top five players in the market now account for 251 percentage points of implied probability. | Outcome | Current Prob | Change | Volume | | :--- | :--- | :--- | :--- | | Alex Smalley | 59% | **+26.0pp** | 77,551 | | Jon Rahm | 54% | **+30.0pp** | 26,993 | | Ludvig Aberg | 52% | +19.0pp | 16,448 | | Rory McIlroy | 46% | **+34.0pp** | 59,006 | | Xander Schauffele | 40% | **+28.0pp** | 11,751 | | Nick Taylor | 32% | **+27.0pp** | 18,213 | | Aaron Rai | 29% | +25.0pp | 20,550 | | Scottie Scheffler | 28% | **-24.0pp** | 137,531 | | Patrick Reed | 24% | +18.0pp | 3,828 | | Maverick McNealy | 22% | -5.0pp | 9,505 | | Matti Schmid | 21% | +21.0pp | 32,627 | | Chris Gotterup | 19% | **-19.0pp** | 15,068 | | Min Woo Lee | 18% | **-18.0pp** | 33,895 | | Hideki Matsuyama | 16% | -10.0pp | 7,488 | | Joaquin Niemann | 15% | +20.0pp | 5,867 | | Justin Rose | 14% | +16.0pp | 12,572 | | Kristoffer Reitan | 14% | **+37.0pp** | 1,492 | | Ben Griffin | 11% | +4.0pp | 1,748 | | ...40 more | ... | ... | ... | *Note: Table abridged for clarity. Full distribution includes 56 outcomes.* **Net: 33 of 56 contracts rose on 354,866 in total volume, while 18 contracts declined on 268,540 in volume, shifting the implied consensus sharply toward the players who finished Round 3 in contention.** ## What's Driving the Shift The repricing appears directly tied to the leaderboard positions established after Saturday's third round of the PGA Championship. * **Smalley Takes the Lead:** Alex Smalley's odds surged to become the market favorite after he finished the third round with a two-shot lead at 6-under par [1]. His strong play on the back nine, which included six birdies, established him as the player to beat heading into the final day, a position now reflected in his 59% implied probability. * **Contenders Emerge From a Crowded Field:** A logjam near the top of the leaderboard broke apart Saturday, with a clear group of contenders emerging. The market reacted by boosting the odds for players like Jon Rahm (+30.0pp), who is in a five-way tie for second place, along with Rory McIlroy (+34.0pp) and Xander Schauffele (+28.0pp), who are both three shots behind the leader [1]. * **Scheffler Falters:** The most significant drop in probability was for defending champion Scottie Scheffler (-24.0pp). This move coincides with his struggles in the third round, where he missed six putts from inside 10 feet and finished the day five shots off the lead [1]. The high trading volume on his contract suggests strong market conviction that his chances of a top-five finish have diminished. ## Market Context This market allows for multiple outcomes to be successful, as five different golfers will ultimately finish in the Top 5. The total implied probability across all 56 contracts is 654%. In a market where exactly five contracts will resolve to 'Yes', the theoretical sum of probabilities should be 500%. The current sum suggests the market sees more than five players with a strong chance, reflecting the competitive nature of the leaderboard where several players are clustered within a few strokes of the lead [1]. The day's trading activity shows a clear reallocation of probability. Volume was heavily concentrated in the contracts for players whose fortunes changed most dramatically during the third round. Scottie Scheffler's contract saw the highest volume (137,531), followed by Alex Smalley (77,551) and Rory McIlroy (59,006), indicating that traders were most active in repricing the odds of the new leader, the surging major champion, and the faltering favorite. ## What to Watch The market will close on June 14, 2026, and will be settled based on the final official leaderboard of the 2026 PGA Championship. The key event is the tournament's final round, scheduled for Sunday, May 17, 2026. The official results will be confirmed by sources including the PGA Tour, ESPN, and Fox Sports [5, 9]. ## Related Analysis - [Read the complete market report for PGA Championship: Top 5 Finishers](/markets/sports/golf/pga-championship-top-5-finishers/) ### Relevant Answer Library - [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) - [How do I read a prediction market price as a probability?](/answers/how-do-i-read-a-prediction-market-price-as-a-probability) - [Browse all Answer Library topics](/answer-library)
