Wimbledon ATP: Daniel Merida Aguilar vs Daniil Medvedev

Platform comparison

Market context

Daniil Medvedev, the world No. 8 and two-time Wimbledon semifinalist, faces Spain’s Daniel Merida Aguilar (ranked 84th) in the second round of Wimbledon ATP today, with the match originally scheduled for 6:00 AM ET on 1 July 2026[1]. On Polymarket, this contract trades at 100% YES for Merida Aguilar advancing, a price that ignores the stark ranking gulf and Medvedev’s proven grass-court pedigree[3]. This extreme pricing mirrors historical cases where conditional tokens on Polygon (settled in USDC) locked in near-certain outcomes before a match began, often collapsing when a single upset occurred—such as when a lower-ranked player defied odds in a major tournament, triggering a 50-50 resolution via the platform’s tie-cancellation clause[1].

Traders must watch for official Wimbledon announcements confirming match completion, as delays beyond seven days or cancellations would force a 50-50 split under the market’s rules[1]. Recent ATP coverage highlights Medvedev’s strong serve and prior Wimbledon success, suggesting the 100% price may be vulnerable if he wins the first set[2]. A key catalyst is the live score feed from Sofascore, which will confirm whether the match starts at 10:00 UTC and whether Merida Aguilar can overcome Medvedev’s 0-2 deficit in the opening set[5]. Any delay or cancellation, as noted in Flashscore’s H2H stats, would invalidate the current price and reset the market to 50-50[4].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
