Contrexeville: Francesca Jones vs Leolia Jeanjean

Platform comparison

Market context

The underlying event is the WTA 125K singles match between Francesca Jones and Leolia Jeanjean at the Grand Est Open 88 in Contrexeville, France, originally set for 4:00am ET on 9 July 2026. Current crowd-implied probability of 0% YES for Jones advancing suggests the market has already priced in her retirement, as live data confirms she retired after losing the first set 1-6 and trailing 0-3 in the second [1]. This aligns with historical precedents where sudden on-court retirements due to injury or illness collapse a player’s win probability to zero within minutes, rendering conditional orders on that side worthless before settlement.

A power-user approaching this programmatically would monitor real-time score feeds and official WTA retirement announcements rather than relying on static odds, which remain misleading until the retirement is confirmed [2]. Key catalysts include the official match result declaration, any subsequent injury reports from the tournament medical team, and the tournament’s finalisation of the draw for the next round [9]. Recent coverage from Tennis.com confirms the match concluded with Jones unable to continue, validating the 0% probability as a factual outcome rather than a speculative guess [9]. Traders should watch for the official resolution timestamp to trigger automated settlement bots, ensuring no delay beyond the seven-day window affects the 50-50 tie clause.

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 Bot UK, which mirrors the Polymarket order book directly.

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

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Bot UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
