Market context

Victoria Mboko and Leylah Fernandez are due to meet in the Internationaux de Strasbourg quarter-finals, an all-Canadian clay-court match that has already been reported as set by the WTA and Sportsnet after both won on Tuesday. Fernandez came through a long three-setter against Magdalena Frech, while Mboko beat Lois Boisson in straight sets after receiving a first-round bye, so the market is looking at a live tennis result rather than a scheduling placeholder.

A 100% YES price is only coherent if traders are treating the contract as a near-certainty that the match is officially on, rather than a view on who wins. In comparable WTA markets, the main risk to a binary settlement is usually not competitive strength but whether the match is actually completed within the settlement window, because cancellation, retirement before completion, or a delay beyond seven days can force a 50-50 outcome under the rules. Mboko also arrived with less clay-court match play, while Fernandez had already logged nearly three hours on court in her previous round, a contrast noted in WTA reporting.

For traders, the key catalysts are the tournament order of play, any late injury or withdrawal news, and whether the quarter-final is started and finished before 2026-05-28 08:30 UTC. On-chain, the market’s value should settle in USDC only once the contract resolves, so any operational delay matters more than pre-match noise. There is no obvious BTC or ETH linkage here unless broader crypto risk moves affect liquidity and spreads on the venue; in practice, the decisive inputs are the official Strasbourg schedule, player fitness updates, and the referee’s final match status.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

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.
