Market context
Hailey Baptiste faces Barbora Krejcikova in the Roland Garros women's draw, scheduled for 24 May 2026. The Polymarket contract currently trades at 100% YES, implying near-certainty that one player will advance. This pricing reflects the match's position within the tournament structure and the conditional token mechanics on Polygon: traders holding YES tokens receive full payout if Baptiste wins, whilst Krejcikova backers would need the market to resolve to her name instead. The settlement window closes 31 May, allowing a week beyond the scheduled date for completion before the 50-50 tie-break clause activates.
Krejcikova enters as the heavier favourite in most conventional sportsbooks, having won three Grand Slam singles titles and maintaining top-10 ranking status. Baptiste, ranked considerably lower, has shown improvement on clay but lacks the tournament pedigree of her opponent. Historical matchups between mismatched seeds at Roland Garros rarely produce upsets; the 100% probability on Polymarket reflects this structural imbalance rather than genuine uncertainty about whether the match occurs. The contract's design—resolving to 50-50 only if cancelled or delayed beyond seven days—makes completion the base case.
Traders should monitor the official Roland Garros draw confirmation and any weather disruptions to the Paris schedule in late May. Injury withdrawals or scheduling conflicts could trigger the tie-break clause, though the French Tennis Federation typically maintains tournament integrity through the first week. Court assignments and match timing announcements typically arrive 48 hours before play, offering a final catalyst for repricing before settlement.
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
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?
- 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.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
