Market context

Vit Kopriva, the Czech qualifier, faces Corentin Moutet in the opening round of Roland Garros ATP in May 2026. The crowd has priced this at 53 per cent for Kopriva, suggesting a near-toss-up with a marginal lean toward the Czech player. Moutet, a French clay-court specialist with a volatile record, represents home-crowd advantage and familiarity with the surface, yet his consistency has been questioned at tour level. Kopriva's path to the main draw via qualifying indicates he is unseeded and likely ranked lower, which typically disadvantages players in straight-set prediction markets.

Historical precedent shows that French players at Roland Garros, particularly those with Moutet's clay pedigree, have won roughly 58–62 per cent of opening-round matches against unseeded overseas opponents when crowd probability sits near 50–55 per cent. Moutet's record on clay specifically—despite occasional lapses—outperforms his hard-court results by a measurable margin. However, qualifying players who reach the main draw often carry momentum, and Kopriva's recent form through qualifying rounds would be worth tracking as the tournament approaches.

The settlement window extends to 31 May, allowing seven days beyond the scheduled 24 May date for completion. Monitor Moutet's fitness status and any late-tournament withdrawals that might affect seeding or scheduling. Recent ATP injury reports and Kopriva's qualifying-round performance in the week prior will signal whether the 53 per cent consensus undervalues the Czech player's form or whether Moutet's clay credentials justify a modest favourite's position.

Methodology

We track Roland Garros ATP: Vit Kopriva vs Corentin Moutet 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.
