Market context

The underlying event is the WTA Wimbledon qualifying match between Aliaksandra Sasnovich and Bianca Andreescu, scheduled for 8:00 AM ET on 25 June 2026 in London. Sasnovich, ranked 113th, recently overcame Storm Hunter in the previous round after a tight 5-7, 6-4 loss to Hunter in the first qualifying set, while Andreescu, holding a 25-12 record in 2026, defeated Fiona Ferro 6-0, 2-0 in Oeiras earlier this month. This is their second meeting overall, with Andreescu winning the sole prior encounter 6-2, 2-6, 6-1 in Beijing’s 2019 first round, though they have never contested a match on grass before.

Historical cases where a 0% crowd-implied probability appeared in qualifying tennis often reflect one player’s severe injury, withdrawal, or overwhelming surface disadvantage; here, Andreescu’s 33-22 grass record and recent W35 Bradenton title suggest she is the clear favourite, yet Sasnovich’s resilience in London’s qualifications (overcoming Teichmann 6-7, 6-1, 6-4) means the 0% line may be premature rather than definitive. Traders should watch for any late injury announcements from either player, as both started from qualifications and lost a set in the event, with Sasnovich conceding two sets versus Andreescu’s one. Recent coverage from TennisTonic notes Andreescu’s 2-1 grass form in 2026 and her Bradenton and Vero Beach titles, while Sasnovich’s 55.9% win rate in 2026 remains solid but less dominant on grass. Monitor the WTA’s official injury list and match-day weather in London, as rain delays could push the settlement window beyond seven days, triggering the 50-50 resolution clause.

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.
