Pronóstico: Liege: Gauthier Onclin vs Florian Broska

Platform comparison

Market context

The tennis match between Gauthier Onclin and Florian Broska in Liege, Belgium, is set to begin tonight at 5:00pm ET on Centre Court, with the market currently pricing Onclin’s advancement at 0% YES. This near-zero probability suggests the crowd believes Onclin faces an overwhelming disadvantage, despite head-to-head records showing both players hold equal career wins[3]. In comparable ATP Challenger scenarios where a favourite is priced at 0%, the outcome typically hinges on a sudden, unannounced withdrawal or a severe pre-match injury rather than a competitive loss on court. Historical data from similar low-probability contracts on Polymarket reveals that when USDC liquidity is thin on Polygon, conditional tokens often resolve to the 50-50 tie clause if the match is delayed beyond seven days without a winner, a mechanism traders must monitor closely[2].

Traders should watch for immediate announcements regarding player fitness or schedule changes, as any delay past the seven-day threshold triggers the 50-50 resolution automatically. Recent coverage from TennisTonic highlights that the match is scheduled for 6:00pm on Centre Court, with no prior indication of withdrawal, yet the market’s 0% pricing implies a hidden dependency not yet public[1]. The key catalyst is the official start time confirmation; if the match begins but is not completed due to weather or injury, the conditional token structure on Polymarket will default to the 50-50 split rather than awarding the win to either player. With the settlement window ending on 16 July 2026, the on-chain mechanics will enforce this resolution strictly, making the 0% price a reflection of the crowd’s belief that Onclin will not advance under any normal competitive circumstance.

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

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.
