Wimbledon ATP: Daniel Merida Aguilar vs Daniil Medvedev

Platform comparison

Market context

The real-world event is the second-round Wimbledon ATP clash between Spain’s Daniel Merida Aguilar (ranked 84) and Russia’s Daniil Medvedev (ranked 8), scheduled for 13:00 Moscow time on 1 July 2026. Medvedev, a two-time Wimbledon semifinalist, is the overwhelming favourite with -5000 odds, implying a 98% win probability, while Merida Aguilar holds +1100 odds and an 8.3% implied chance [1][4].

Historically, such extreme odds in Grand Slam second rounds—where a top-10 player faces a qualifier or low-ranked opponent—almost never deviate from the implied probability unless injury or weather intervenes. In comparable cases from recent Wimbledon editions, matches with similar moneylines resolved to the favourite in over 97% of instances, with cancellations being the primary outlier [1][2]. For a programmatic trader, this market functions as a near-arbitrage utility: conditional orders can lock in the 100% YES position with minimal slippage, treating the settlement as a deterministic outcome unless the match is delayed beyond seven days.

Traders should monitor live score feeds for start-time confirmations and any pre-match injury announcements, as Medvedev’s physical condition is the only credible catalyst for probability shift. The match begins at 16:05 Moscow time, and any delay beyond this window without a winner triggers the 50-50 resolution clause [3][7]. Recent tournament coverage confirms Medvedev is expected to win in three sets, reinforcing the current crowd-implied certainty [2]. No external news source has reported a withdrawal, so the 100% YES position remains grounded in the ranking gulf and historical precedent [5].

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

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.
