Arzhankin vs Arce Fernandez

This market covers a first-round men's singles match at the 2026 ITF M15 Kursumlijska Banja tournament between Anton Arzhankin and Mario Arce Fernandez, originally scheduled for July 8, 2026. Both Kalshi and Polymarket list a straightforward head-to-head: the market resolves to whichever player advances, with tie-breaker rules for walkovers, cancellations, or mid-match retirements broadly aligned across the two venues. Anton Arzhankin is the clear favourite. Kalshi prices him at 96.0%, while Polymarket has him at 79.0%, producing a consensus of roughly 96.0% and marking Arce Fernandez as a heavy underdog at 24.0% on Kalshi and 21.0% on Polymarket. Total volume sits around $10,178, with the bulk of activity concentrated on Kalshi ($10,178 in volume and $9,198 in liquidity) versus a thinner $578 on Polymarket. The notable feature here is the 17-point gap on Arzhankin between Kalshi (96.0%) and Polymarket (79.0%), which likely reflects Polymarket's very shallow liquidity rather than a genuine disagreement about the match. The cross-platform takeaway: both venues agree Arzhankin is a strong favourite, but Kalshi's deeper book pushes his implied probability materially higher than Polymarket's thinly traded quote.
