Market context
Ajla Tomljanovic meets Veronika Erjavec in Eastbourne qualifying, with the match listed for 21 June and both players already visible on live-score and tournament pages for the event.[2][6] The crowd-implied 100% Yes suggests the market is effectively pricing in the match being played and producing a winner, rather than a cancellation or prolonged delay.
The form case points to Tomljanovic being the more established grass-court option: one preview notes she has won four grass matches in six outings this month, while Erjavec has played only one match in Eastbourne qualifying.[1] That gap matters because qualifying on grass often rewards recent match sharpness, and Tomljanovic’s higher WTA ranking in the live listings also supports the perception that she enters as the more proven player.[3] Head-to-head appears to be 0-0, so there is no direct match-up history to lean on.[1]
The main trader watchpoints are scheduling and whether either player is forced into a compressed turnaround by earlier rounds or court delays, which can change how a qualifying match is priced. Tournament and score pages indicate the fixture is on the day’s Eastbourne qualifying slate, so any late withdrawal, walkover, or postponement would be the key event risk for resolution rather than a deep form swing.[2][6] One current preview is already framing Tomljanovic as the stronger outright and even leans to a straight-sets win, which is consistent with the market’s one-sided view.[1]
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
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.
- What does it cost to trade on Sport Prediction?
- Zero. Sport Prediction routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- 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.
- 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.
