Market context

The All England Lawn Tennis and Croquet Club will host the 2026 Women's Singles Championship from 29 June to 12 July. The tournament operates under standard WTA rules, with a 128-player draw progressing through qualifying and main draw rounds. A player must complete all seven matches to claim the title; withdrawal, disqualification, or injury after the draw closes results in "No" resolution for that player's market. The 19% crowd probability reflects uncertainty across a field where no single competitor has yet dominated the 2025–26 season sufficiently to establish clear favouritism at this early stage.

Historical precedent suggests Wimbledon outcomes remain volatile relative to other majors. Between 2015 and 2024, only three players won multiple titles, whilst unseeded or lower-ranked entrants reached finals in five instances. Serena Williams' 2016 loss to Angelique Kerber and Markéta Vondroušová's 2023 semi-final exit despite top seeding illustrate how grass-court form diverges sharply from hard-court rankings. Current probability distribution typically reflects this unpredictability: a 19% YES reading suggests traders expect the named player to finish within the top five contenders but face genuine competition from four or more alternatives.

Key catalysts include WTA rankings freezes in spring 2026, grass-court preparation tournaments in June (Birmingham, Eastbourne), and injury announcements within two weeks of the draw. Traders should monitor ITF grass-court records and recent Wimbledon qualifying performance. Regulatory accessibility varies: German GlüStV permits trading up to €1,500 without KYC verification; US CFTC oversight applies to US-domiciled traders regardless of market size, requiring compliance checks through the host platform. UK-based traders face no specific KYC threshold for this market under current Gambling Commission guidance, though platform-level verification remains standard practice.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Where can I trade this market with the lowest fees?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
