Pozoblanco: Paul Inchauspe vs Hamish Stewart

Platform comparison

Market context

Paul Inchauspe and Hamish Stewart are scheduled to compete in a Pozoblanco tennis match on 13 July 2026, with the contest originally set for 4:00 AM ET. The market currently reflects 100% implied probability for Inchauspe, suggesting either strong historical precedent, recent form data, or significant information asymmetry regarding Stewart's fitness or availability. The settlement window extends to 20 July, allowing a seven-day buffer for rescheduling before the market defaults to 50-50 resolution.

Historical precedent in lower-tier professional tennis markets shows that 100% probabilities typically emerge when one player has withdrawn, announced injury, or when tournament draws reveal a significant ranking disparity. Comparable Challenger-level matches with similarly skewed probabilities have occasionally reversed when late withdrawals trigger walkovers or when scheduling changes force unexpected substitutions. Traders automating conditional orders should flag any ATP or ITF announcements regarding player status changes, as these often precede official tournament communications by several hours.

The critical catalyst window runs from the scheduled date through 20 July. Monitor the Pozoblanco tournament's official draw updates and both players' social media for withdrawal notices or injury statements. Programmatic traders should set alerts for ITF or ATP injury reports and cross-reference against tournament scheduling pages; delays beyond 13 July without a completed match trigger the 50-50 resolution clause, creating arbitrage opportunities if the market hasn't already repriced that tail risk.

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.
