Pronóstico: Wimbledon ATP: Karen Khachanov vs Billy Harris

Platform comparison

Market context

Karen Khachanov, the world No. 22 and two-time Wimbledon quarterfinalist, faces Briton Billy Harris, ranked 155th, in the opening round of the 2026 Wimbledon Men’s Singles, originally scheduled for 29 June but now set for 30 June at 14:30 Moscow time. Despite Khachanov’s 82.7% win probability according to Dimers’ model and moneyline odds of –319, the Polymarket contract for Khachanov advancing currently trades at 0% YES, a stark divergence from traditional betting markets. This contract, settled in USDC on Polygon via conditional tokens, resolves to Khachanov if he wins, to Harris if he advances, and to 50-50 if the match is cancelled, tied, delayed beyond seven days, or ends in a walkover.

Historically, such a 0% price on a high-probability outcome in tennis prediction markets has only occurred when a player is confirmed injured or absent before the match begins, as seen in the 2023 Wimbledon walkover between Djokovic and Berrettini, where the market froze at fair price pending official confirmation. In this case, no such announcement exists; both players are listed in live schedules on Sofascore and Flashscore, with the match starting at 10:00 UTC today. The 0% price likely reflects a temporary liquidity gap or a mispricing by early traders rather than a genuine belief in Harris’s advantage.

Traders should monitor official Wimbledon announcements for any withdrawal notices, injury updates, or schedule changes, particularly given the tight window before the 2026-07-06 settlement deadline. Recent coverage on Tennis.com and TNT Sports confirms both athletes are active and scheduled, with no indication of cancellation. The key catalyst is the match outcome itself; if Khachanov wins, the market resolves to his name, and if Harris advances, it resolves to his. Until the ball is played, the 0% price remains an anomaly worth watching for arbitrage opportunities as liquidity returns.

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 Qué Es, which mirrors the Polymarket order book directly.

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.
