Centurion 2: Philip Henning vs Alexander Donski

Market context

Philip Henning faces Alexander Donski in a Centurion 2 tennis match scheduled for 7 June 2026 at 5:00 AM ET. The Polymarket contract currently prices this at 100% YES, reflecting either near-certainty that the match occurs and produces a decisive result, or insufficient liquidity to move the price from its initial state. On-chain settlement depends on whether one player advances cleanly; any cancellation, tie, or delay exceeding seven days from the scheduled date triggers a 50-50 resolution, whilst an abandoned match mid-play also defaults to split odds.

Centurion events are relatively recent additions to professional tennis calendars, with limited historical precedent for predicting completion rates. Standard ATP and Challenger tour matches show cancellation rates below 2% when scheduled, though early-morning fixtures (particularly at 5:00 AM ET) carry marginally higher withdrawal risk due to travel fatigue and scheduling conflicts. Neither Henning nor Donski holds a ranking suggesting injury-prone patterns, though lower-ranked players on secondary tours experience fixture changes more frequently than top-100 competitors.

Traders should monitor the official Centurion 2 schedule for any postponements or player withdrawals in the week preceding 7 June. Weather forecasts for the venue become material 72 hours before play. Recent ATP Challenger announcements typically surface on the ATP website and official tournament channels; any player injury updates or scheduling revisions would immediately affect the conditional token's validity. The settlement window extends to 14 June, allowing a seven-day grace period for rescheduling before the market resolves to 50-50.

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

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.
