Roland Garros ATP: Ugo Humbert vs Quentin Halys

Platform comparison

Active sub-markets

Market context

Ugo Humbert and Quentin Halys, both French players, are scheduled to meet in the opening rounds of Roland Garros in May 2026. The match carries particular weight given the domestic rivalry context and the tournament's significance as a Grand Slam event on clay. Settlement depends on a completed match result by 3 June 2026; any cancellation, tie, or unresolved delay beyond seven days triggers a 50-50 resolution.

The 0% implied probability reflects the market's current state rather than analytical consensus on the matchup itself. Historical precedent suggests French domestic clay-court encounters at Roland Garros rarely sustain extreme probability skew unless one player has withdrawn or injury news surfaces beforehand. Comparable early-round French pairings typically see modest probability spreads (60-40 to 70-30 ranges) unless recent form data or head-to-head records strongly favour one player. The flat probability here likely indicates minimal trading activity or pending confirmation of player fitness.

Traders monitoring this market should track official Roland Garros draw confirmations and ATP injury bulletins through May. Schedule changes occasionally occur at Grand Slams, particularly if weather disruptions cascade through earlier rounds. For programmatic approaches, conditional orders tied to ATP ranking updates or official withdrawal announcements would capture material shifts. The settlement window's 7-day grace period creates edge cases worth monitoring—if either player contests a walkover or retirement decision, resolution could extend into early June. Recent ATP communications typically appear via official tournament channels and player social media within 48 hours of scheduling changes.

Methodology

We track Roland Garros ATP: Ugo Humbert vs Quentin Halys on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
