Wimbledon ATP: Soon-Woo Kwon vs Martin Landaluce

Platform comparison

Market context

The underlying event is the first-round ATP men’s singles match at Wimbledon between Soon-Woo Kwon and Martin Landaluce, scheduled to begin at 6:00 AM ET on 29 June 2026. The prediction market currently implies a 100% YES probability that Kwon will advance, yet this diverges sharply from sportsbook lines and analyst consensus. FanDuel prices Landaluce as the favourite to win 3-0 at +280, while Tennis Tonic explicitly picks Landaluce to win in five sets, citing his 25-19 win-loss record in 2026 and the absence of any prior head-to-head between the players[2].

Historically, such 100% implied probabilities in open prediction markets on unplayed matches have resolved to near-50% outcomes when no walkover or pre-match withdrawal occurs, particularly in grass-court tournaments where form is volatile. Comparable cases from recent Wimbeldon rounds show that even players with strong recent handicaps—Kwon won +2.5 sets in 11 of his last 12 ATP Wimbeldon matches—can be overturned by opponents with superior aggregate records, as Landaluce’s 3-3 set record in 2026 suggests[7]. Traders should watch for official AELTC announcements on player fitness, any walkover declarations before 6:00 AM ET, and the live set score progression, as a match ending in a tie or cancellation beyond seven days resolves to 50-50[3]. No walkover has been reported as of 5:39 PM UTC today, meaning the market’s certainty is unsupported by real-time dependencies.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets UK, which mirrors the Polymarket order book directly.

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.

FAQ

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
