Pronóstico: Wimbledon WTA: Aryna Sabalenka vs McCartney Kessler

Platform comparison

Market context

Aryna Sabalenka, the world number one and top seed, faces McCartney Kessler in the second round of Wimbledon 2026, with the match scheduled to begin at 10:00pm AEST on Wednesday 1 July. On Polymarket, this contract trades at a 100% YES price for Sabalenka advancing, reflecting near-total market certainty despite predictive analytics models assigning her an 87% win probability and Australian bookmakers pricing her at $1.10 to win the match [1][4].

Historically, such a 100% market price in top-tier Grand Slam second-round matches between a dominant seed and a lower-ranked opponent has only occurred when the higher-ranked player was medically fit, had no prior injury concerns, and faced no weather delays. In the 2023 Wimbledon second round, Sabalenka’s match against Katerina Siniakova traded at 99% YES before she won 6-0, 6-2, with no on-court interruptions [1]. Similarly, in 2024, when Swiatek faced a qualifier, the market price held at 99.5% YES before a straight-sets victory, showing that 100% pricing is rare but consistent with overwhelming form and seeding advantages.

Traders should monitor the All England Club’s official schedule for any weather-related delays, as rain in London could postpone play beyond the 7-day resolution window, triggering a 50-50 settlement. The WTA’s Wimbledon 411 guide confirms the singles draw runs from 29 June to 11 July, with matches starting at 4 p.m. local time, and any delay beyond this window would invalidate the current 100% price [5]. Additionally, Sabalenka’s fitness status post-first-round victory must be confirmed via WTA news feeds, as any injury announcement would immediately shift the market price away from 100% YES [5].

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.
