Kubka vs Bertacchi

This market covers a women's professional tennis match between Martyna Kubka and Anastasia Bertacchi at the ITF W35 Don Benito quarterfinal, originally scheduled for July 10, 2026. Each moneyline outcome resolves to the player who advances, with standard tennis-market provisions for walkovers, retirements, and cancellations. Kalshi, Polymarket, and Azuro all listed the head-to-head, with Kalshi carrying the bulk of activity at roughly $132,810 in volume. Martyna Kubka is the overwhelming favourite, priced at a 99.9% consensus. Polymarket has her at 99.9%, Kalshi at 99.0%, and Azuro noticeably lower at 95.2%. Bertacchi's implied probability mirrors this: 0.1% on Polymarket, 1.0% on Kalshi, but 11.2% on Azuro. That leaves Azuro as the clear outlier on both sides of the moneyline, though its volume on this event is negligible ($1), which likely explains the stale pricing. Beyond the moneyline, Polymarket and Azuro also list totals and handicap markets, with Kubka -1.5 games at 80.0% and Kubka -5.5 at 59.5% on Azuro. The cross-platform takeaway: Kalshi and Polymarket agree Kubka is a near-certain winner, while Azuro's thinly traded book leaves Bertacchi materially more expensive to back against.
