Market context

The All England Club will host the 2026 Women's Singles championship across the grass courts of Wimbledon from 29 June to 12 July. The 19% implied probability reflects a fragmented field where no single player commands overwhelming consensus. This pricing sits between the historical norm—where the favourite typically carries 25–35% of the total probability mass—and the reality of women's tennis in 2025–26, where injury, form volatility, and surface-specific preparation create genuine uncertainty across multiple contenders.

Wimbledon's grass-court specialisation has historically compressed favourite odds relative to other majors. Serena Williams won five titles but never carried more than 30% implied probability on the eve of play; Ashleigh Barty's 2021 victory came at 18% after a year away from competition. The current 19% suggests the market is pricing either a genuinely open draw or a consensus favourite whose odds have drifted due to recent injury concerns or ranking fluctuations. Comparing this to Roland Garros or the Australian Open, where clay and hard courts reward consistency, grass demands specific preparation windows and carries higher injury risk in the weeks preceding the tournament.

Traders should monitor ranking movements and injury reports through May and June 2026, particularly for players ranked in the top 20 who traditionally perform well on grass. Wimbledon's seeding system directly influences draw difficulty; a player seeded outside the top four faces a substantially harder path. Recent form on grass—the Eastbourne International and Birmingham Classic typically precede Wimbledon—will signal readiness. Any late withdrawals from the warm-up events or announcements regarding ongoing physical issues should trigger reassessment of the favourite's viability.

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

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.
