Market outcomes
| ITF Nakhon Pathom: Kamonwan Yodpetch vs Anchisa Chanta | 28% YES | 73% NO |
| Completed Match | 49% YES | 51% NO |
Kamonwan Yodpetch and Anchisa Chanta will compete in the ITF Women's circuit event at Nakhon Pathom, Thailand, scheduled for 13 May 2026. The match represents a lower-tier professional tennis fixture where both players are competing for ranking points and prize money on the International Tennis Federation circuit. The current order book on Polymarket reflects a 28% implied probability for Yodpetch's advancement, suggesting the market views Chanta as the favoured competitor. This probability has formed through the cumulative trading activity of participants pricing in available information about both players' recent form, head-to-head records, and surface conditions.
Both players operate primarily within the ITF circuit, where historical precedent shows that recent tournament results and ranking trajectories significantly influence match outcomes. Players competing at this level typically have limited public match data compared to WTA-ranked competitors, meaning traders must rely on ITF rankings, recent tournament placements, and any available head-to-head history. The 28% probability suggests the market has identified factors favouring Chanta, though the relatively modest gap leaves meaningful uncertainty about the actual match dynamics.
Traders should monitor for any official tournament withdrawals or schedule changes from the ITF's published fixture list, as the settlement window extends to 21 May 2026, allowing seven days beyond the scheduled date. Court surface conditions at Nakhon Pathom and any late injury announcements could shift the probability, though such information rarely surfaces widely for ITF-level matches. Confirmation of the match proceeding as scheduled remains the primary catalyst affecting settlement certainty.
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 market has been open for under a month — fresh enough that information asymmetry remains a real factor.
