Market context
The upcoming Wimbledon WTA second-round match between Katerina Siniakova and Nikola Bartunkova is set to begin at 10:00 UTC on 1 July 2026 in London, with the current market pricing Bartunkova as the near-certain winner at a 0% implied probability for Siniakova advancing. This contract trades on Polymarket using USDC on the Polygon network, where conditional tokens resolve automatically once the match concludes, reflecting the on-chain mechanics that bind settlement to the official result.
Historically, grass-court tournaments have produced stark upsets when lower-ranked players exploit surface unfamiliarity, yet Siniakova’s 0% market price mirrors past cases where a player’s withdrawal or forfeiture before the first ball was struck triggered a fair-price resolution rather than a competitive outcome. In similar WTA matches at Wimbledon, markets have collapsed to near-zero for one side when pre-match data showed a severe fitness deficit or a confirmed walkover, as seen in Kalshi’s resolution rules for postponed or unstarted matches where the market closes after a fair price is determined [4].
Traders should monitor the official Wimbledon draw updates and any late injury announcements from the WTA, as a withdrawal before the match starts would resolve the contract to a fair price rather than a competitive result. Recent coverage from Tennis Majors confirms this is a second-round grass match with no prior head-to-head data between the Czech players, meaning any sudden schedule change or medical report could shift the conditional token outcome dramatically [9]. The settlement window ends on 8 July 2026, so any delay beyond seven days without a winner would trigger the 50-50 resolution clause.
Methodology
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 Polymarket Qué Es, which mirrors the Polymarket order book directly.
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.
