Jankanj vs Funk

This market covers the ITF Men's M15 Kursumlijska Banja Round of 32 tennis match between Vlado Jankanj and Aaron Funk, originally scheduled for July 8, 2026. Both Polymarket and Kalshi list the head-to-head, resolving to whichever player advances. Polymarket treats retirements or defaults after play begins as a win for the advancing player and sends walkovers to 50-50, while Kalshi requires that a ball be played and resolves cancellations before that point at $0.50. Pricing across the two venues is one-sided in favour of Jankanj. Kalshi has him at 99.0% with Funk at 1.0%, while Polymarket is even more extreme at 99.9% for Jankanj and just 0.1% for Funk. That makes Jankanj the overwhelming favourite by roughly 98 percentage points on either book, a level typically seen once a match is effectively decided or already progressing decisively. Kalshi has absorbed the vast majority of the activity here, with about $115,000 in volume versus under $1,000 on Polymarket. The cross-platform takeaway: both venues agree Jankanj is a near-certain winner, with only a sub-one-point spread separating Polymarket's tighter 99.9% mark from Kalshi's 99.0%.
