Market context
Liudmila Samsonova faces Jil Teichmann in a Roland Garros women's singles match scheduled for 24 May 2026. The current Polymarket pricing reflects zero probability for Samsonova's advancement, suggesting the conditional token structure values Teichmann's progression as near-certain. On-chain liquidity in USDC pairs will determine whether traders can efficiently enter positions ahead of the match, with settlement contingent on a decisive result by 31 May 2026.
Samsonova has demonstrated clay-court inconsistency over recent seasons, whilst Teichmann's record on Roland Garros surfaces shows marginal performance in qualifying rounds and main draws. Historical matchups between players of comparable ranking at this venue typically see the higher-seeded player advance in roughly 65–70% of cases. The 0% implied probability suggests market participants are pricing in either a substantial seeding advantage for Teichmann or recent form data indicating Samsonova's withdrawal risk.
Traders should monitor official Roland Garros draw announcements and player injury reports through May, as both competitors have experienced fitness concerns in preceding months. Schedule changes remain possible given tournament logistics, and any delay beyond seven days without completion triggers the 50-50 resolution clause. Recent ATP and WTA scheduling adjustments have occasionally compressed match windows, affecting conditional token valuations for clay-court events. Confirmation of both players' participation in qualifying or main-draw rounds will be the primary catalyst reshaping on-chain pricing before settlement.
Methodology
We track Roland Garros WTA: Liudmila Samsonova vs Jil Teichmann 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
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.
