Wimbledon ATP: Jan-Lennard Struff vs Daniil Medvedev

Platform comparison

Market context

The upcoming third-round clash at Wimbledon pits Jan-Lennard Struff against Daniil Medvedev on Court 3, with the match scheduled to begin at 12:30 PM BST today. In the prediction market, Struff advancing is currently priced at 45% YES, implying a slight edge for Medvedev to progress, which aligns with the initial betting odds where Medvedev sits at 1.189 against Struff’s 4.7[1].

Historically, this rivalry has been heavily skewed, with Medvedev leading the head-to-head record 9-2 and securing two wins over Struff on hard courts in 2025 alone[2][8]. While Wimbledon is a grass tournament, the pattern of Medvedev dominating Struff in recent years suggests that the 45% probability for Struff is a generous valuation, mirroring past third-round encounters where the higher-ranked player consistently outperformed the underdog[2].

Traders should monitor the live on-court conditions and any weather delays, as the match is set to start shortly and any disruption could trigger the 50-50 settlement clause if unresolved beyond seven days[3]. The primary catalyst is the immediate performance on grass, given Medvedev’s preference for faster surfaces and his tactical ability to neutralise Struff’s serve, a factor highlighted in recent pre-match analysis from Tennis Tonic[1]. On-chain, the contract resolves via conditional tokens on Polygon using USDC, meaning liquidity will shift rapidly once the first set concludes[1].

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
