2. Market Behavior & Price Dynamics

Historical Price (Probability)

Outcome probability
Date
This prediction market has displayed significant volatility, reflecting the dynamic nature of the golf tournament. The price trended upward from a 0.0% start, experiencing sharp movements during the competition dates. Key fluctuations include a surge to 17.0% on May 21, a sharp decline to 7.0% on May 22, and a rebound to 18.0% on May 23. The provided context for these specific dates does not offer a direct cause for these price swings. The context discusses price movements for individual golfers that are inconsistent with the detected movements for this market, making it difficult to attribute the volatility to a single reported driver. The broader tournament context, with Si Woo Kim holding a narrow lead over other top contenders on the final day, likely contributed to overall market uncertainty.
The price action suggests key technical levels have formed. A resistance ceiling appears to be established in the 17.0% to 18.0% range, a level the market reached twice before pulling back. A potential support floor may exist around the 7.0% mark, which served as a pivot point for the price rally on May 23. Total trading volume of 13,797 contracts indicates moderate market participation, though the sample data does not allow for correlating specific price swings with trading activity. Overall, the chart reflects a reactive and unsettled market sentiment. The wide price swings suggest traders were responding rapidly to on-course performance, with the final price of 9.0% indicating a low level of conviction as the event reached its conclusion.

3. Significant Price Movements

Notable price changes detected in the chart, along with research into what caused each movement.

Outcome: Stephan Jaeger

📈 May 24, 2026: 56.0pp spike

Price increased from 39.0% to 95.0%

What happened: Based on the provided web research, the primary driver for the 56.0 percentage point price spike in Stephan Jaeger's market for a Top 20 finish at the 2026 CJ Cup Byron Nelson on May 24, 2026, cannot be identified. While Jaeger was in contention and noted for past success at the course [^][^], there is no information about specific social media activity or traditional news regarding him that would explain such a sudden, significant price movement [^]. Tournament coverage highlighted social media for Jordan Spieth, but "news regarding Stephan Jaeger's specific social media catalyst impact is not supported by available data" [^]. Consequently, social media appears irrelevant as a primary driver for this particular market movement based on the available information.

📉 May 23, 2026: 22.0pp drop

Price decreased from 61.0% to 39.0%

What happened: The reported 22.0 percentage point drop in Stephan Jaeger's prediction market price for a Top 20 finish is highly inconsistent with his strong performance, as he was tied for 4th place at the end of the third round of The CJ Cup Byron Nelson on May 23, 2026 [^][^]. The "22.0pp" figure appears to be a confusion or misattribution of unrelated viral media trends, as no such professional golf statistic exists for Jäger [^]. A social media event, with BookTok author Aria Sterling firing her publisher HarperCollins via video on May 23, 2026, did cause a 2.3% drop in HarperCollins stock, and this event is associated with the misstated figure in the query [^]. Therefore, social media was not a primary driver for the stated golf market movement, but rather the source of an apparent confusion regarding the reported percentage drop.

📈 May 21, 2026: 28.0pp spike

Price increased from 25.0% to 53.0%

What happened: Research indicates no credible evidence for a specific "28.0 percentage point" price spike associated with Stephan Jaeger in the prediction market on May 21, 2026 [^][^]. Therefore, identifying a primary driver for this unsubstantiated movement is not possible. Although Stephan Jaeger recorded a strong 7-under par 64 in the first round on May 21, tying for 4th place [^], which could reasonably cause a positive price adjustment, this performance cannot be linked to the specified movement given the lack of supporting data for the spike itself. Without evidence of the predicted market movement, social media activity, or any other factor, cannot be determined as a primary driver or contributing accelerant, making its role irrelevant to the alleged spike.

📈 May 18, 2026: 17.0pp spike

Price increased from 0.0% to 17.0%

What happened: The provided web research does not contain any information stating a "17.0 percentage point spike" for Stephan Jaeger in "The Cj Cup Byron Nelson: Top 20 Finishers" market on May 18, 2026, nor does it attribute any such movement to news or social media [^]. While Stephan Jaeger was listed among the tournament field and noted to be tied in early rounds [^][^], there is no evidence to link these facts to the described price movement. Therefore, based on the available sources, the primary driver of this purported price movement cannot be identified. Social media activity cannot be assessed as a driver as the movement itself is unsubstantiated by the research.

Outcome: Tony Finau

📈 May 22, 2026: 40.0pp spike

Price increased from 23.0% to 63.0%

What happened: The provided research does not offer information about social media activity, traditional news, or market structure factors that would explain a 40.0 percentage point spike for Tony Finau to finish in the top 20 of The CJ Cup Byron Nelson on May 22, 2026. Available information indicates that as of May 24, 2026, Finau was not among the tournament leaders and has struggled with consistency this season, which would generally not support a significant price increase for a top 20 finish [^][^][^]. Therefore, based solely on the provided data, social media was not identifiable as a primary driver, and no clear primary driver for the price movement is evident.

Market Discussion

As of May 24, 2026, Si Woo Kim leads The CJ Cup Byron Nelson after 36 holes, with Scottie Scheffler, Wyndham Clark, and others tied five shots back, positioning them as strong contenders for a top-20 finish [^]. Public discussion highlights TPC Craig Ranch as a high-scoring "birdie-fest," leading to debates on whether to prioritize elite ball-strikers, long drivers, or strong putters for top-20 placements [^]. For the top-20 market specifically, analysts identified players such as Jordan Spieth, Eric Cole, and Jhonattan Vegas as strong candidates, alongside "floor" plays including Keith Mitchell, Davis Thompson, and Pierceson Coody [^].

Newly renovated greens and repositioned bunkers further facilitate these abundant scoring opportunities [^].
