Pozoblanco: Paul Inchauspe vs Hamish Stewart

Platform comparison

Market context

Paul Inchauspe and Hamish Stewart are scheduled to meet in a Pozoblanco tennis fixture originally set for 13 July 2026. The match carries a settlement window extending to 20 July 2026 at 08:00 UTC, allowing a seven-day buffer for rescheduling before the market defaults to a 50-50 split. Both players compete on the lower-tier professional circuit where fixture cancellations and delays occur more frequently than on ATP or WTA main tours, making the scheduling buffer material to outcome probability.

The 100% implied probability on Inchauspe reflects either incomplete market information or an assumption that the match will proceed as scheduled. Historical precedent from regional European clay tournaments shows that July fixtures in Spain rarely face weather-related postponements, though player withdrawals due to injury or scheduling conflicts account for roughly 8–12% of lower-ranked professional matches. Traders should monitor entry lists and official tournament updates from the Pozoblanco organisers, typically published 48–72 hours before play, as late scratches reshape match probabilities substantially.

A programmatic approach would flag this market as illiquid given the 100% reading; conditional orders tied to official tournament confirmation announcements would reduce execution risk. Watch for player injury reports or ATP Challenger circuit schedule conflicts that might force withdrawal. The seven-day resolution window creates arbitrage opportunities if the match is delayed: traders holding positions can reassess based on rescheduled dates and updated player form data before the 50-50 default triggers.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
