Platform comparison

Active sub-markets

Market context

The underlying real-world event is the ATP Challenger tennis match in Piracicaba between Maximo Zeitune and Nicolas Zanellato, which was originally scheduled for 23 June 2026 but has already been played on 25 June 2026, with Nicolas Zanellato securing a decisive victory. The market’s 100% YES crowd-implied probability reflects the completed result where Zanellato advanced, making the outcome certain rather than speculative.

Historically, prediction markets on tennis matches that resolve after the event has concluded exhibit near-perfect accuracy, as seen in Kalshi’s ATP Challenger markets where post-match settlements consistently align with official match reports[4]. Comparable cases from the 2025 Brazil Challenger series show that once a match is played and a winner determined, market probabilities converge to 100% for the advancing player, eliminating any uncertainty regarding cancellations or delays[2].

Traders should monitor official ATP Tour head-to-head records and tournament withdrawal notices, though these are now irrelevant given the match completion[8]. The primary catalyst the market leans on is the confirmed game report from 365scores, which documents Zanellato’s 6–4, 7–6 win, confirming his advancement and resolving the market definitively[1]. No further announcements or schedules will alter this outcome, as the settlement window remains open only for administrative finalisation until 30 June 2026.
