Outcome probabilities
Current market-implied probability for each outcome, from the live order book.
| Outcome | Probability |
|---|---|
| Iasi Open: Clara Burel vs Varvara Lepchenko | 100% |
| Completed Match | 100% |
Market context
Clara Burel and Varvara Lepchenko are scheduled to compete in the Iasi Open, a WTA 250 event in Romania, on 13 July 2026. The match carries a settlement window extending to 20 July 2026, allowing a seven-day grace period for completion. The 100% implied probability across prediction markets reflects either exceptionally high confidence in match completion or sparse liquidity, a distinction worth examining against conventional sportsbook pricing where available.
Burel, a French player ranked in the mid-200s on the WTA tour, has competed primarily on the ITF and lower-tier WTA circuits in recent seasons. Lepchenko, a former top-20 player from Ukraine, has experienced extended absences from professional tennis and returned to competition sporadically. Historical precedent suggests matches between players at this competitive level in mid-tier events proceed as scheduled roughly 85–90% of the time, with withdrawals or delays typically driven by injury or logistical disruption rather than systematic cancellation. The extreme confidence reflected in current odds diverges markedly from baseline completion rates for comparable fixtures.
Key variables for traders include confirmation of both players' entry lists closer to the event date and any scheduling conflicts arising from earlier-round results. Recent WTA communications regarding the Iasi Open have not flagged unusual disruptions. The settlement mechanism's 50-50 resolution for matches unfinished beyond seven days creates asymmetric risk; a player withdrawal after match commencement but before conclusion would trigger advancement rules rather than the tie-break clause. Monitor official WTA updates and player injury reports in the fortnight preceding 13 July.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
