## About

This market covers a Round of 16 men's professional tennis match between Shinji Hazawa and Colin Sinclair at the 2026 M25 / ITF Brisbane event, originally scheduled for July 15, 2026. Traders on Kalshi and Polymarket priced the head-to-head winner, with side markets on totals (over/under game lines) also listed on Polymarket. Under Kalshi's rules, a match cancellation before a ball is played would resolve at $0.50, while a mid-match retirement resolves against the retiring player; Polymarket applies similar walkover and retirement conventions.

On the headline winner market, Colin Sinclair is the clear favourite, priced at 99.0% on Kalshi against just 1.0% for Hazawa. Kalshi carried essentially all of the liquidity here, with roughly $3.99M in volume versus about $5.2K on Polymarket.

The most striking feature of the snapshot is the cross-platform spread on the same head-to-head: Polymarket's separate ITF Brisbane market prices Sinclair at only 36.5% and Hazawa at 63.5%, a 62.5-point gap versus Kalshi's line. Polymarket's various over/under totals sit at or near 50%, suggesting those legs are largely untraded. The takeaway: Kalshi and Polymarket disagree sharply on who is favoured in this match, an unusually wide divergence concentrated on the thinly traded Polymarket side.
