Market context
Emma Raducanu and Solana Sierra are scheduled to meet in the first or second round of the 2026 Roland Garros women's singles draw on 24 May. The 0% implied probability reflects either extreme uncertainty about whether the match will occur as scheduled, or a technical issue with market liquidity at the time of snapshot. Raducanu, a former US Open champion, typically carries higher seeding and ranking advantage in such matchups, though her injury history and clay-court form remain variables. Sierra, ranked substantially lower, would require a significant upset to advance.
The regulatory treatment of this market depends on trader jurisdiction. Under the German GlüStV framework, prediction markets on sports outcomes fall within the licensed betting category; operators must hold explicit approval, though the market's settlement window extends beyond typical match-day windows, potentially affecting how German regulators classify it. US CFTC oversight applies if the platform accepts US traders; the CFTC has asserted authority over event derivatives, though enforcement remains selective. The "no-KYC up to $1,500" threshold commonly cited by platforms means traders can deposit and trade without identity verification below that cumulative exposure, though this does not exempt the underlying market from regulatory classification—it merely reflects customer onboarding policy rather than substantive exemption.
Key catalysts include official draw confirmation (typically 48–72 hours before play), injury announcements affecting either player, and weather delays at Roland Garros, which frequently push matches beyond their scheduled slots. The settlement window's 7-day grace period is material: if the match is postponed but completed within that window, resolution proceeds normally. Traders should monitor ATP/WTA injury bulletins and the official Roland Garros schedule updates, particularly given the early morning ET slot (5:00 AM), which may affect match timing if court allocations shift.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
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.
FAQ
- Where can I trade this market with the lowest fees?
- On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- 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.
- 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.
- 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.
- 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.
