Market context
Coco Gauff faces Solana Sierra in the second round of the Wimbledon WTA, originally set for 6:00 AM ET on 1 July 2026, with the market currently pricing a 12% chance that Sierra advances. On Polymarket, this contract trades at 0.12 USDC per share on the Polygon network, reflecting conditional tokens that will resolve to Sierra if she wins, Gauff if she wins, or a 50-50 split if the match is cancelled, tied, or delayed beyond seven days without a winner.
Historically, Sierra has shown resilience against Gauff despite a rankings gap, notably rallying past her in Rome after trailing by a double break in the third set, though Gauff ultimately won 5-7, 6-0, 6-4[3]. This prior scare suggests Sierra is not a pushover, yet Gauff’s dominance in subsequent matches—including a 6-1, 6-1 victory at the United Cup in Perth[4]—frames the 12% probability as a realistic but cautious assessment of Sierra’s narrow path to victory.
Traders should monitor live score updates from Court 1 in London, where the match begins at 13:10 UTC, and watch for any weather-related delays or injury announcements that could trigger the 50-50 resolution clause[6]. Recent form indicates Gauff is primed for another decisive win, but Sierra’s ability to force tight sets remains a key catalyst, as noted in pre-match previews highlighting the clear rankings disparity[2]. Any shift in momentum or unexpected retirements will directly impact the on-chain settlement, making real-time data from Flashscore or Sofascore essential for timing share purchases[5][6].
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 Argentina, which mirrors the Polymarket order book directly.
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.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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 Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Argentina trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
