Market context

Pablo Carreno Busta and Jiri Lehecka are scheduled to meet in the first or second round of Roland Garros in May 2026, with the match originally set for 5:00 AM ET on 24 May. The current prediction-market probability of 36% for Carreno Busta reflects a market view favouring Lehecka, the younger Czech player ranked significantly higher on the ATP circuit. At 36%, the implied odds suggest roughly a 2:1 advantage for Lehecka, though sportsbook lines typically reflect tighter margins on clay-court matchups involving established players like Carreno Busta, who remains a dangerous competitor on the surface despite age-related ranking decline.

Carreno Busta's historical record on clay—particularly at Roland Garros, where he reached the semi-finals in 2017—provides context for the current probability. Lehecka, by contrast, has shown inconsistent clay-court form relative to his hard-court results, though his ranking trajectory and recent tournament performances suggest upward momentum. The 36% probability sits between typical sportsbook lines on such pairings and reflects genuine uncertainty; neither player is a clear favourite in the way seeding alone might suggest.

Traders should monitor injury reports and training updates through May, as both players' preparation schedules and any late-tournament withdrawals could shift match likelihood. The 7-day delay clause in the settlement terms means weather disruptions at Roland Garros could trigger a 50-50 resolution if the match extends beyond 31 May without completion. Recent form in April and early May warm-up events will provide the most reliable signal for recalibrating the current 36% reading.

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

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.

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.

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.

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.
