Market outcomes
| Zagreb (Doubles): Duda/Latinovic vs Ivanisevic/Simundza | 83% YES | 18% NO |
| Completed Match | 50% YES | 51% NO |
The Zagreb doubles match between Duda/Latinovic and Ivanisevic/Simundza represents a lower-tier ATP event pairing, scheduled for May 14, 2026. The 83% implied probability on Polymarket's order book currently favours Duda/Latinovic to advance. This probability reflects real-time positioning among traders on the platform, with the spread between bid and ask orders establishing the current consensus. The settlement window extends to May 21, allowing a seven-day buffer for scheduling delays before triggering the 50-50 tie-break clause.
Comparable doubles matches at regional ATP events typically see favourites priced between 70-85% when one pairing holds a clear ranking or recent form advantage. The current 83% mark sits at the higher end of this range, suggesting traders perceive a material gap in either seeding, recent results, or partnership chemistry. Zagreb's clay court surface and the specific draw positioning will influence whether this probability holds or shifts materially in the days before play.
Key catalysts include official draw confirmations, any last-minute withdrawals or substitutions, and player injury updates from competing tournaments in the preceding week. The early morning scheduling (4:00 AM ET) may affect liquidity on the order book closer to match time. Traders should monitor ATP communications regarding the tournament schedule, particularly if weather or venue issues force rescheduling beyond the seven-day window, which would trigger automatic 50-50 resolution regardless of on-court outcome.
This market settles from the official outcome published at https://www.atptour.com/en/scores/current. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
