Market outcomes
| ITF Nakhon Pathom: Yatawee Chimcham vs Elyse Tse | 22% YES | 79% NO |
| Completed Match | 50% YES | 51% NO |
Yatawee Chimcham, a Thai player competing on the ITF circuit, faces Elyse Tse in a Women's ITF event at Nakhon Pathom scheduled for 14 May 2026. The current order book on Polymarket prices Chimcham's advancement at 22 per cent, implying Tse is favoured at 78 per cent. This pricing reflects the relative ranking and recent form assessments available to traders as of the settlement window opening.
ITF Women's matches at lower-tier venues typically see pricing driven by WTA ranking differentials and recent tournament results. Chimcham competes primarily on the ITF circuit with limited WTA exposure, whilst Tse's recent activity and ranking trajectory inform the substantial probability gap. Historical ITF matchups show that when ranking gaps exceed 100–150 positions, the higher-ranked player wins roughly 70–80 per cent of the time, though surface preference and recent match fitness introduce variance. The Thai venue may offer marginal home advantage for Chimcham, though this rarely shifts odds materially in professional tennis.
Traders should monitor any withdrawals or injury announcements between now and 14 May, as ITF players frequently withdraw due to scheduling conflicts or minor injuries. The settlement window extends to 21 May, allowing seven days for completion; matches abandoned mid-play without a winner resolve to 50–50 under the market terms. Recent ITF scheduling data suggests Nakhon Pathom events typically proceed on schedule, reducing the likelihood of extended delays. Court surface conditions and weather forecasts closer to the event date may influence late trading activity.
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.

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 $318 of resting liquidity puts this market in the below the median by volume for sports 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.
