The prediction market for a Top 20 finish at the 2026 CJ Cup Byron Nelson saw a dramatic repricing on Friday, May 22, 2026, following an explosive second round of play. Probabilities surged for players who posted low scores, with contracts for Jordan Spieth (+37.0pp), Tony Finau (+40.0pp), and Tom Hoge (+47.0pp) seeing the most significant gains on high volume. This upward shift was funded by a broad reallocation of probability away from players who faded or are positioned near the cut line, including a sharp 68.0-percentage-point drop for Seung-Yul Noh. The market is now heavily concentrated around the tournament's new leaders, reflecting the leaderboard shakeup at TPC Craig Ranch [1], [4].
Distribution Analysis
The market repricing was widespread, with 39 of the 67 eligible contracts rising in value while 27 declined. The volume heavily favored the risers, with over 143,000 contracts traded on gaining players compared to approximately 55,700 on decliners. This indicates a strong consensus shift toward the top of the leaderboard. Si Woo Kim, who holds a five-shot lead after a second-round 60, saw his Top 20 probability solidify at 97% [2], [3]. The most notable downward move was a 68.0-point drop for Seung-Yul Noh, though it occurred on minimal volume.

Net: 39 of 67 contracts rose on over 143,000 in total volume, concentrating the market's implied probability around players who posted low scores in Friday's second round.
What's Driving the Shift
The significant market repricing appears to be a direct reaction to the second-round results, where soft course conditions and little wind led to exceptionally low scores and a major leaderboard shuffle [7], [8].
Kim's Dominant Performance: Si Woo Kim's spectacular 11-under 60 on Friday gave him a commanding five-shot lead at 18-under par [2], [4]. His performance, which nearly resulted in the 16th sub-60 round in PGA Tour history, cemented his status as a near-lock for a top finish, pushing his probability to 97%.
Widespread Low Scoring: The market scrambled to keep up as numerous players surged up the leaderboard. Sungjae Im shot a 10-under 61 that included a hole-in-one, while Jordan Spieth and Tom Hoge carded 9-under 62s [3], [8]. These performances vaulted them into contention and drove massive gains in their respective Top 20 contracts, with traders aggressively buying into their strong form.
Post-Cut Reassessment: The cut line was established at 6-under par [1]. Players who finished near or below that line saw their chances of a Top 20 finish plummet. This includes sharp drops for Austin Eckroat (-41.0pp), who finished T53, and Jonathan Byrd (-38.0pp), also at T53 [5]. Seung-Yul Noh's 68.0-point fall, the largest in the market, appears to be a correction from a previously high valuation, exacerbated by very thin liquidity, as indicated by a 24-hour volume of just four contracts.
Market Context
This "Top 20 Finishers" market structure allows for multiple winning outcomes, with a total implied probability currently at 2279%. The high volume directed toward the players who climbed the leaderboard on Friday indicates strong conviction from traders that the weekend's contenders have now been clearly established.
While the drop in Noh's contract triggered this analysis, the broader and more significant story is the market's decisive rally around the top of the leaderboard. The movement reflects a classic repricing event in a sports market, where real-time performance data immediately and drastically reshapes future expectations.
What to Watch
Traders will now be focused on the third and fourth rounds of the tournament, scheduled to conclude on Sunday, May 24, 2026. The PGA Tour has adjusted Saturday's tee times due to the threat of inclement weather, which could introduce volatility and affect course conditions [6]. The market will settle based on the final official leaderboard published by sources including the PGA Tour [9].
