Wimbledon WTA: Ajla Tomljanovic vs Mariam Bolkvadze

Platform comparison

Market context

Ajla Tomljanovic has already secured victory over Mariam Bolkvadze in their first-round Wimbledon WTA clash, confirming the 100% YES probability on the market that she will advance. The match, originally slated for 29 June 2026, was played on 30 June at Court 11, where Tomljanovic prevailed in straight sets, ending any doubt about the outcome before the settlement window closes in July 2026[1][4].

Historically, such 100% crowd-implied probabilities in tennis prediction markets rarely shift once a match is completed, as seen in prior Wimbledon rounds where decisive straight-set wins locked in outcomes immediately[2]. In cases where one player dominates early, markets like this have consistently resolved without delay, mirroring Tomljanovic’s 83% pre-match win chance projected by predictive models, which proved accurate in real time[2][3].

Traders should now monitor official WTA announcements confirming Tomljanovic’s progression to the next round and any updates on her schedule for the second round, as these will finalise the market’s resolution[1]. No further match-related catalysts remain, given the result is settled; the only dependencies are administrative confirmations from the All England Lawn Tennis and Croquet Club regarding the official record of the match[4]. With the outcome confirmed, the market will resolve to ‘Ajla Tomljanovic’ without ambiguity.

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

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.
