Market context
Liudmila Samsonova and Anastasia Potapova are scheduled to meet in the second round of the Internazionali BNL d'Italia on 9 May 2026. The Polymarket contract currently prices Samsonova's advancement at 100%, reflecting either extreme confidence in her form or minimal liquidity depth; the conditional token mechanics on Polygon mean any shift in available information will immediately reprice USDC-denominated positions. The settlement window closes 16 May, allowing a seven-day buffer for delays before the market resolves to 50-50 split.
Both players are Russian nationals competing on the WTA circuit. Samsonova has historically held a winning record against Potapova in their head-to-head matchups, though Potapova has shown improvement in recent seasons and has taken sets off higher-ranked opponents. The current 100% probability reflects this historical edge rather than certainty; comparable second-round matches at Masters 1000 events typically see probability ranges of 65–85% for the favoured player, suggesting the market may be overweighting Samsonova's advantage or underweighting Potapova's recent trajectory.
Traders should monitor injury reports and draw confirmations released by the WTA in the week preceding the event. Samsonova's recent tournament results and court-surface performance on clay will be critical; the Foro Italico's red clay often favours players with strong baseline consistency. Any withdrawal or late scheduling changes would trigger the seven-day delay clause, making fixture confirmation a key catalyst for repricing before the 16 May settlement deadline.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
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.
