Platform comparison

Market context

The underlying real-world event is the men’s singles semi-final at the Lexus Eastbourne Open, where Zizou Bergs faces Toby Samuel in a match originally scheduled for 6:00 AM ET on 26 June 2026. The market currently implies a 100% YES probability that Bergs advances, placing him as the overwhelming favourite against Samuel, who is priced as the underdog with just a 21.2% chance of winning according to statistical models[1].

Historically, matches with such extreme crowd-implied probabilities often resolve in line with consensus when the favourite holds a clear serve advantage and superior first-serve points, as Bergs does with 83% points won behind his first serve compared to Samuel’s lower efficiency[7]. Comparable cases from recent ATP semi-finals show that when a player’s first-serve percentage exceeds 50% and their ace count is significantly higher—Bergs has 20 aces versus Samuel’s 14—the outcome rarely deviates from the implied probability unless weather or injury intervenes[7].

Traders should monitor official tournament announcements for any delay beyond the seven-day cancellation window, which would trigger a 50-50 resolution, and watch for live updates on Samuel’s first-serve percentage, which currently sits at just 35.4%[2]. The key dependency is whether Bergs maintains his 53.6% first-serve dominance throughout the match, as a drop below 45% could open a contrarian angle for Samuel despite the current consensus[2]. Recent coverage from TennisTonic confirms Bergs’ strong display and statistical edge, reinforcing the value spot in the current pricing[7].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
