Market context

The underlying event is the ATP Mallorca Championships men’s singles match between Lorenzo Sonego of Italy and Miomir Kecmanovic of Serbia, originally set for 23 June 2026 at 7:30 AM ET. Sonego has already defeated Kecmanovic in the Round of 16, with the final score recorded as 6–4, 6–4 in Sonego’s favour, meaning the match in question has already concluded and Kecmanovic did not advance[5]. This historical outcome directly explains the current 0% YES probability for Sonego advancing against Kecmanovic, as the contest is no longer pending.

Comparable cases in ATP tournaments show that when a match result is already determined, prediction markets reflecting future advancement of the same players correctly settle to zero probability, as no replay or rescheduling occurs under standard ATP rules[4]. Traders should monitor official ATP communications for any rare exceptions, such as injury-related withdrawals that might trigger a reschedule, though such cases are exceptionally uncommon in men’s singles. Recent tournament updates confirm Kecmanovic’s withdrawal from the next round, reinforcing the finality of Sonego’s victory[8].

From a regulatory perspective, German GlüStV and US CFTC frameworks treat settled markets as non-tradable, while the “no-KYC up to $1,500” provision allows limited accessibility for users in jurisdictions with relaxed identity verification, though this market’s settled status renders it inaccessible for new trades regardless of KYC thresholds. The settlement window ending 30 June 2026 at 11:30 AM ET confirms the market’s closure, with no further catalysts expected.

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.
