Market outcomes
| Bengaluru 2: Ilya Ivashka vs Kokoro Isomura | 81% YES | 19% NO |
| Completed Match | 50% YES | 50% NO |
Ilya Ivashka, the Belarusian left-hander ranked around 50th on the ATP tour, faces Japan's Kokoro Isomura in the opening round of the Bengaluru ATP 250 event scheduled for 13 May 2026. The 80% implied probability on Polymarket's order book reflects Ivashka's ranking advantage and experience edge; Isomura, a qualifier or lower-ranked entrant, typically faces steeper odds in such matchups. The settlement window extends to 20 May, allowing a week for the match to conclude before resolution triggers the 50-50 tie clause.
Ivashka's recent form and surface preference provide the foundation for current pricing. The Belarusian has competed regularly on hard courts across the ATP circuit and holds a career record against lower-ranked opponents that justifies favouring him in opening rounds. Isomura, whilst capable on hard courts, lacks the tour-level consistency that would narrow this gap materially. Historical ATP 250 first-round matchups between players of similar ranking differential typically settle near 75–85% for the higher-ranked player, placing this market's 80% within expected bounds.
Traders should monitor official ATP scheduling confirmations and any injury withdrawals in the lead-up to 13 May. Weather disruptions in Bengaluru during May are possible but unlikely to delay play beyond the seven-day window. Court assignments and match order could affect player preparation and fatigue, though these details emerge only days before the event. No recent news suggests either player faces fitness concerns that would materially shift the current probability.
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.
