2. Market Behavior & Price Dynamics

Historical Price (Probability)

Outcome probability
Date
This market, predicting a win for Coco Gauff, has shown significant volatility against a generally downward trend. The contract opened at 68.0% and briefly spiked to a high of 77.0% on May 10. However, this was immediately followed by a sharp 18.0 percentage point drop on May 11, bringing the price to its current and lowest point of 59.0%. This steep decline represents the most significant price movement in the market's history and has defined its current trajectory. Trading volume patterns underscore the conviction behind this downward shift. Initial trading was light, including during the spike to 77.0%, but the subsequent crash to 59.0% occurred on a massive volume of over 348,000 contracts, indicating a strong consensus driving the price down.
The price action appears disconnected from the provided external context. While betting markets and expert previews consistently favor Gauff, with implied probabilities around 75%, this prediction market has moved in the opposite direction. The spike on May 10 and the subsequent sharp drop on May 11 are not explained by the available news, which was published prior to these movements and consistently positioned Gauff as the heavy favorite. This divergence suggests that market participants may be acting on information or interpretations not captured in the public consensus. The peak of 77.0%-78.0% acted as a clear resistance level that was swiftly rejected. The current market sentiment, priced at 59.0%, reflects significantly more skepticism about a Gauff victory than is indicated by traditional sports betting odds.

Price decreased from 77.0% to 59.0%

Outcome: Coco Gauff

What happened: The provided web research does not contain specific social media activity or traditional news that directly explains an 18.0 percentage point drop for Coco Gauff in the prediction market on 2026-05-11. An Instagram post from TennisChannel on 2026-05-09 announced the Gauff vs. Jovic match [^], which is scheduled for 2026-05-11 in Rome [^], [^].

While a "ranking points drop date" for Iva Jovic is noted [^], its link to Gauff's 18.0pp price drop is unconfirmed, and no specific timing or causal mechanism is provided.
