Wimbledon WTA: Dayana Yastremska vs Jessica Bouzas Maneiro

Platform comparison

Market context

The Wimbledon WTA match between Dayana Yastremska and Jessica Bouzas Maneiro, originally set for 1 July 2026, has already concluded with Bouzas Maneiro advancing. On-chain data on Polymarket prices the "YES" outcome for Yastremska at 0%, reflecting the settled result where Bouzas Maneiro defeated Yastremska 6-3, 6-7(1), 6-2 in the second round [1]. The contract, settled in USDC on Polygon via conditional tokens, now holds a definitive resolution rather than a speculative probability, as the underlying event is no longer pending.

Historically, similar markets where a match result is known before settlement window closure resolve instantly to the actual winner, rendering the crowd-implied probability moot. In this case, Bouzas Maneiro’s victory was confirmed on 2 July, and the market’s 0% price for Yastremska aligns with the factual outcome [1]. Comparable cases from prior Grand Slam events show that once a match is played and a winner determined, conditional tokens automatically execute to the correct party, eliminating any ambiguity or delay in settlement.

Traders should monitor official WTA announcements for any potential match cancellations or delays beyond the seven-day window, though none are expected given the match has already occurred. Bouzas Maneiro’s progression to the fourth round of a Grand Slam for the first time in her career is the key catalyst, confirmed by the tournament’s official results [8]. No further action is required on the contract, as the settlement window ending 8 July 2026 will simply formalise the already-determined result.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

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.
