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 Round of 64 at Wimbledon today, with the match set to begin at 13:00 Moscow time. The market currently implies a 100% chance that Medvedev advances, a stark contrast to the betting odds where Medvedev holds -5000 favour compared to Merida Aguilar’s +1100 underdog status, translating to an implied 98% win probability for the Russian[1].

Historically, 100% implied probabilities in individual sports like tennis are rare and often signal either a mispriced market or an event that has effectively already concluded before the settlement window; comparable cases in ATP tournaments show that such extreme odds usually accompany matches where one player is significantly outclassed on the specific surface, as grass favours Medvedev’s aggressive baseline style over Merida Aguilar’s lower-ranked versatility[2]. The fact that the market has locked at 100% suggests traders have already priced in Medvedev’s superior grass-court pedigree, having reached two Wimbledon semifinals, while Merida Aguilar lacks comparable high-level experience at this venue[5].

Traders should monitor the official match start confirmation and any potential injury updates from the All England Lawn Tennis and Croquet Club, as a cancellation or delay beyond seven days would reset the market to a 50-50 split[1]. While Medvedev is the clear pick to win in three sets, the key catalyst remains the match’s actual commencement; any delay in the 13:00 Moscow time slot or a sudden withdrawal would invalidate the current certainty[3]. Recent analysis from Tennis Tonic confirms Medvedev as the pick, noting his ability to beat stronger opponents in straight sets, reinforcing the market’s confidence in his advancement[2].

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.
