Market context
Panna Udvardy is set to face Katarzyna Kawa in the Round of 16 at the Iasi Open tonight, with the prediction market currently pricing Udvardy’s advancement at a 100% implied probability. On Polymarket, this contract trades on USDC over the Polygon network, where conditional tokens reflect absolute certainty in the Hungarian player’s progression. The settlement window remains open until 23 July 2026, locking in the outcome once the match concludes or is officially ruled.
Historically, such 100% pricing in tennis markets on-chain usually signals either a walkover, a pre-match withdrawal, or an overwhelming statistical edge confirmed by form. In comparable WTA events, contracts hitting full certainty often precede a player’s unchallenged advance due to opponent injury or administrative cancellation before the first serve. Here, the stats favour Udvardy decisively, with preview analysis explicitly tipping her to win against Kawa, reinforcing the market’s confidence [1].
Traders should monitor the official Iasi Open schedule for any late announcements regarding Kawa’s fitness or court assignment, as even a minor delay could trigger the 50-50 resolution clause if the match exceeds the seven-day threshold. With the match scheduled for 3:00 AM ET tonight, the primary catalyst is the start-time confirmation and any real-time injury updates from the tournament’s official feed. Absent such disruptions, the on-chain price is likely to hold until settlement.

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
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 PolyGram 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.
