Market outcomes
| ITF Andong: Sohyun Park vs Malaika Rapolu | 62% YES | 39% NO |
| Completed Match | 50% YES | 50% NO |
Sohyun Park and Malaika Rapolu are scheduled to compete in the ITF Women's tournament in Andong on 13 May 2026. The market currently reflects a 62% implied probability favouring Park's advancement, formed across Polymarket's order book as traders price the matchup. Settlement occurs by 21 May 2026, allowing a seven-day window for completion; matches not finished within that period or cancelled outright resolve to 50-50.
Park competes regularly on the ITF circuit, where outcomes depend heavily on recent form, surface preference, and head-to-head records. ITF Women's matches at this tier typically see favourites priced between 55–70% when there exists meaningful historical data or ranking differential. The current 62% reading suggests traders perceive a moderate but not overwhelming advantage to Park, likely reflecting either comparable recent results or modest ranking separation. Rapolu's presence at Andong indicates she holds sufficient ranking points or qualifying credentials to merit seeding consideration, which constrains how far the probability can drift without fresh information.
Traders should monitor tournament draw confirmations, any withdrawal announcements, and surface conditions at the Andong venue, as hard court performance varies significantly amongst lower-ranked players. Injury reports or late schedule adjustments in the days before 13 May could shift the order book materially. Weather delays are common at ITF events in May; the seven-day settlement window provides buffer, but extended rain could trigger the 50-50 clause if no winner emerges by 21 May.
This market settles from the official outcome published at https://www.itftennis.com/en/tournament-calendar/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
