Wimbledon ATP: Jan-Lennard Struff vs Daniil Medvedev

Platform comparison

Market context

The third-round Wimbledon ATP clash between Jan-Lennard Struff and Daniil Medvedev is set for Friday, 3 July 2026, with the crowd-implied probability of Struff advancing standing at 45% YES. Medvedev, ranked eighth, is the overwhelming favourite, having won both prior career meetings against Struff on hard courts in 2025, while Struff has never progressed beyond the third round in his 11 previous Wimbledon appearances[1][9].

Historical precedents suggest Medvedev’s dominance on grass remains strong, with betting previews predicting a four-set victory and at least 21 games played, though both players are expected to win a set[1]. Comparable third-round encounters in recent years show higher-ranked players like Medvedev typically cover game spreads, with Cloudbet offering Medvedev -5.5 games at 1.69, reflecting the decimal odds divergence between traditional books like FanDuel and implied probability platforms such as Polymarket[2][6].

Traders should monitor live court conditions at Court 3 and any weather delays, as Wimbledon’s grass can favour Medvedev’s baseline style, while fee structures and KYC requirements differ significantly between Kalshi’s regulated US model and Betfair’s global access[2]. Recent ATP head-to-head data confirms Medvedev’s superiority, making the 45% Struff probability a potential value play if grass conditions shift unexpectedly, though most sources still favour Medvedev to win in four sets[1][4].

FAQ

Which platform has the deepest liquidity?

Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.

Is Betfair a Polymarket alternative?

Only partially. Betfair Exchange is UK-focused with a sports-betting emphasis; they have politics markets but with thinner liquidity than Polymarket. Settlement in GBP/EUR, 2-5% commission on winnings.

What about Smarkets as an alternative?

Are all these platforms regulated?
