Zug: Jerome Kym vs Philip Henning

Platform comparison

Market context

Jerome Kym and Philip Henning were scheduled to meet in Zug on 22 July 2026, and this market pays out on which player *advances* if the match is played to a result. In prediction-market terms, a **YES** share means Jerome Kym advances; a **NO** share means Philip Henning advances, while a cancellation, tie, or delay beyond seven days would settle 50-50 under the market rules. The current crowd-implied probability of 0% YES suggests the market is pricing Jerome Kym as having no chance to be the advancing player, which is an unusually extreme reading for a live tennis contest.[1]

For context, very low or zero-priced outcomes in tennis markets often reflect missing information rather than certainty, especially when the official scoreline, draw status, or walkover details are not yet confirmed. Comparable cases on smaller tours can move sharply if a player withdraws, if a match is postponed, or if the event feed lags behind the actual result, so the key question is not only who was stronger on paper but whether the fixture was completed in the form the market requires. A 0% price is therefore best read as a snapshot of market sentiment, not proof that the result is impossible.[1]

The main catalysts to watch are the tournament’s match updates, any retirement or walkover notice, and whether the contest is marked as completed by the relevant score provider. Because the market settles on *advancement*, not merely the scheduled start, a player can still win the market through an opponent retirement if the match begins but does not finish. If the published draw or live score feed changes, traders should treat that as the decisive signal; if nothing is formally recorded within the seven-day window after the scheduled date, the market rules point to a 50-50 settlement.[1]

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 Prediction Market UK, which mirrors the Polymarket order book directly.

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.
