Iasi Open: Paula Badosa vs Anhelina Kalinina

Platform comparison

Market context

Paula Badosa is already confirmed to have advanced past Anhelina Kalinina at the Iasi Open, as the match originally scheduled for 13 July has been resolved with Badosa winning. The crowd-implied probability of 100% YES reflects this completed outcome, not a live contest, meaning the market has effectively settled before the official resolution window closes on 20 July 2026.

Historically, prediction markets on tennis matches that resolve to a definitive winner before the settlement deadline behave like post-event bets, where the probability locks at 100% once the result is confirmed by official WTA records. Comparable cases from recent WTA tournaments show that once a match result is published on the official site or major sports data providers like Tennis Explorer, markets stop trading and reflect the outcome with near-zero variance [1][6].

Traders should monitor the official WTA match result page and Tennis Explorer for any late amendments, though such changes are rare once a scoreline like Badosa’s victory is recorded. No further announcements or schedule dependencies remain relevant, as the match is complete and the winner determined. The only catalyst now is the formal confirmation by the tournament organiser, which is already reflected in current odds [1][2].

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Today trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
