Market context
Coco Gauff faces Anastasia Potapova in the women's singles draw at Roland Garros, with the match originally scheduled for 30 May 2026 at 05:00 ET. The settlement window closes on 6 June at 09:00 UTC, allowing a seven-day buffer for completion or rescheduling. The current 100% YES probability reflects Gauff's seeding and recent form, though this extreme reading leaves no margin for upsets, withdrawals, or scheduling disruptions common in clay-court tournaments.
Gauff's head-to-head record against Potapova and their respective clay-court performances provide the baseline for reassessing this probability. Gauff has competed consistently at Roland Garros, reaching the quarter-finals in recent editions, whilst Potapova, ranked lower, has struggled to maintain momentum on the WTA circuit. Historical clay-court matchups between players of similar calibre show that seeded players advance roughly 75–85% of the time in early rounds, suggesting the market's 100% reading is overconfident. Injury withdrawals at Roland Garros occur in approximately 3–5% of scheduled matches, adding genuine tail risk.
Traders should monitor official Roland Garros draw confirmations and any injury reports from either player in the week preceding the match. Weather delays on clay courts can push matches beyond their scheduled time; the settlement window's seven-day extension mitigates this, but late-stage rescheduling occasionally triggers technical disputes. On-chain USDC settlement will execute once the match result is confirmed by the ATP/WTA official database, typically within hours of completion.

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?
- BTC Prediction 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.
- 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 BTC Prediction?
- Zero. BTC Prediction routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
