Kenzhibayeva vs Tupitsyna

This market covers a Round of 16 tennis match at the 2026 W15 Astana ITF Women's event between Sandugash Kenzhibayeva and Ekaterina Tupitsyna. Each platform resolves to the player who advances, with slightly different handling of walkovers and cancellations: Kalshi refunds to $0.50 if no ball is played, while Polymarket applies a 50-50 split for cancellations, walkovers, or delays beyond seven days. Volume is concentrated almost entirely on Kalshi, which has logged roughly $1.29m in turnover against Polymarket's $380. Ekaterina Tupitsyna is the clear favourite, with a cross-platform consensus of 99.0%. Kalshi prices her at 99.0% and Kenzhibayeva at 1.0%, indicating traders there view the outcome as effectively settled. Polymarket, on much thinner liquidity, is noticeably less lopsided at 90.5% for Tupitsyna and 9.5% for Kenzhibayeva, an 8.5-point spread on the same outcome. The gap almost certainly reflects Polymarket's minimal activity rather than a genuine difference of opinion, since one-sided book pricing on tiny volume tends to leave wider margins. The cross-platform takeaway: both venues agree Tupitsyna is the heavy favourite, but Kalshi's deeper market prices her closer to certainty than Polymarket's thin book.
