Market outcomes
| ITF Fukui: Chia Yi Tsao vs Yui Ohwaki | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Chia Yi Tsao and Yui Ohwaki are scheduled to meet in the ITF Women's Fukui tournament on 26 May 2026. The match is set for 10:45 PM ET, with settlement occurring by 3 June 2026. Currently, Polymarket's order book reflects a 100% implied probability, indicating that traders are pricing this as a near-certain event to occur and resolve to a winner. This extreme probability typically emerges when a match is imminent, venue and player confirmations are locked, and no material uncertainty remains about whether the match will be played.
ITF Women's circuit matches at this level rarely face cancellation once scheduled within a week of play, particularly at established venues in Japan. Historical resolution patterns show that ITF events in Asia maintain strong operational continuity. The 100% probability here reflects confidence that the match will proceed to completion rather than any assessment of which player will win—the market structure treats match occurrence and player advancement as a single binary event.
Traders should monitor the ITF's official draw confirmations and any weather alerts for the Fukui region in late May, though disruption risk is minimal at this stage. Player injury announcements or late withdrawals would be the primary catalyst to shift this probability, though such developments are uncommon within 48 hours of scheduled play. The settlement window extends to 3 June, providing a seven-day buffer for any unforeseen delays.

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.
