Market context
Kaitlin Quevedo and Laura Samson are scheduled to meet in the Modena tournament on 11 June 2026. The match carries a settlement window extending to 18 June, allowing a seven-day grace period for rescheduling before the market defaults to a 50–50 split. The 0% crowd probability reflects either minimal trading activity or strong consensus that one player will not participate, though both are active professionals on the ITF and WTA circuits.
Historical precedent suggests that matches involving lower-ranked players at secondary European clay events experience higher cancellation and withdrawal rates than Grand Slam fixtures. Quevedo and Samson's recent form, injury status, and entry confirmations remain the primary determinants of whether this match materialises. Recent ITF rankings and tournament draw confirmations typically emerge 48 to 72 hours before the scheduled start date; traders should monitor official Modena tournament communications and the WTA website for withdrawal announcements or schedule adjustments.
From a regulatory standpoint, this market operates under German GlüStV provisions if accessed from the EU, with CFTC oversight applying to US-based traders. The no-KYC threshold of $1,500 USD permits retail participation without identity verification up to that stake level on polymarket-kyc.co.uk, though position limits and settlement procedures remain subject to platform terms. Traders should verify their jurisdiction's local betting and derivatives regulations before committing capital, as prediction markets occupy a contested legal space across different territories.
Methodology
We track Modena: Kaitlin Quevedo vs Laura Samson on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
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.
