The prediction market for a Top 20 finish at the 2026 Texas Children's Houston Open repriced sharply following the conclusion of the second round on Friday, March 27, 2026. Probabilities surged for players atop the leaderboard, most notably for tournament leader Gary Woodland, whose chances jumped 58.0 percentage points to 96%. The broad shift reflects the market consolidating its expectations around a clear group of front-runners, reallocating probability away from players who fell further down the standings after 36 holes of play at Memorial Park Golf Course [1, 2].
The repricing was widespread among the tournament's top performers. Alongside Woodland, Nicolai Højgaard (+26.0pp), Min Woo Lee (+30.0pp), and Jason Day (+22.0pp) all saw significant gains in their probability of a top-20 finish after strong second-round performances placed them securely in the top five [2]. In total, 37 of the 65 tracked contracts saw their probabilities rise. Conversely, probability shifted away from players like Chris Gotterup (-31.0pp) and Michael Brennan (-32.0pp), who sit further back from the leaders heading into the weekend.
Distribution Analysis
The market shows a clear stratification, with a dozen players now priced above 50% for a top-20 finish, directly correlating with their positions on the live leaderboard. Gary Woodland's 96% probability reflects his commanding lead.

Net: 37 of 65 contracts rose on a combined volume of 96,578, shifting the market's consensus to strongly favor players currently positioned at or near the top of the leaderboard after two rounds.
What's Driving the Shift
The significant repricing is a direct reaction to on-course results from the first 36 holes of the tournament. The market is adjusting pre-tournament expectations to align with the current leaderboard realities.
- Woodland's Dominant Lead: The primary catalyst for the market-wide shift is Gary Woodland's performance. He followed an opening round 64 with a 7-under 63 on Friday, reaching a total score of -13 and establishing a three-shot lead over the nearest competitors [2, 5]. His probability for a top-20 finish has soared to 96%, reflecting the market's view that he is a near-lock to remain among the leaders.
- Challengers Separate from the Pack: Players immediately behind Woodland also saw their probabilities rise after strong second rounds. Nicolai Højgaard tied a Memorial Park course record with an 8-under 62 to move into a tie for second at -10 [2, 5]. Defending champion Min Woo Lee and Jason Day both shot 7-under 63 to climb into a tie for fourth at -9 [2, 5]. These performances created a clear top tier on the leaderboard, which the prediction market promptly priced in.
- Probability Reallocated from Mid-Tier: The surge in probability for the leaders was funded by declines for players who either struggled or failed to keep pace. For instance, Chris Gotterup (T46 at -3) and Michael Brennan (T33 at -4) saw their top-20 chances plummet by over 30 percentage points each [1, 2]. This reflects a typical mid-tournament dynamic where early favorites who are now far from the lead see their chances diminish significantly.
Market Context
This market allows traders to bet on whether any of the 65 listed golfers will finish in the top 20. Because up to 20 outcomes can resolve as "Yes," the sum of probabilities across all contracts (currently 2308%) far exceeds 100%. The movement on Friday is a classic example of a sports prediction market adjusting to live, in-play information. The high volume on many of the contracts experiencing significant price changes—such as Sahith Theegala (13,352) and Chris Gotterup (17,045)—indicates a liquid market with high conviction behind the repricing.
The tournament is being held at Memorial Park Golf Course in Houston, TX, from March 26-29, with a total purse of $9.9 million [3, 7].
What to Watch
The market will continue to be highly active during the third and fourth rounds on Saturday, March 28, and Sunday, March 29. Traders will be watching to see if Woodland can maintain his lead or if challengers from the chasing pack can close the gap. The market is scheduled to close on April 26, 2026, well after the tournament's conclusion, with settlement based on the final official leaderboard published by sources including the PGA Tour and ESPN [6, 2].
