Market outcomes
| ITF Nakhon Pathom: Wishaya Trongcharoenchaikul vs Takuya Kumasaka | 13% YES | 87% NO |
| Completed Match | 50% YES | 50% NO |
Wishaya Trongcharoenchaikul, a Thai player, faces Japan's Takuya Kumasaka in an ITF Men's event at Nakhon Pathom scheduled for 13 May 2026. The market currently prices Wishaya's victory at 13% on Polymarket's order book, reflecting substantial backing for Kumasaka. The match sits within the lower-tier professional circuit where ranking gaps and recent form carry outsized predictive weight.
ITF Men's matches at this level typically favour players with consistent ATP ranking progression or recent tournament wins. Kumasaka, competing regularly on the ITF circuit, would need to show clear recent momentum or a documented head-to-head advantage to justify the 87% implied probability against Wishaya. Historical ITF upsets do occur—particularly when home-court advantage (Nakhon Pathom is in Thailand) combines with a player entering form—but the current crowd positioning suggests confidence in Kumasaka's baseline superiority.
Traders should monitor draw confirmations and any late withdrawals closer to 13 May, as ITF scheduling changes remain common. Recent injury reports or ranking updates for either player would shift the order book; Polymarket's current liquidity reflects today's information set. The settlement window extends to 21 May, providing a seven-day buffer for delayed matches, though cancellation or tie outcomes would trigger a 50-50 resolution. Court surface conditions at Nakhon Pathom and any last-minute ranking shifts in the week before play represent the primary catalysts for repricing.
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.
The mechanics for trading "ITF Nakhon Pathom: Wishaya Trongcharoenchaikul vs Takuya Kumasaka" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$0 in lifetime turnover and $221 of resting liquidity puts this market in the below the median by volume for games contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
