ITF Granby: Mao Mushika vs Cadence Brace

Platform comparison

Market context

Mao Mushika and Cadence Brace face off in the ITF Women’s Granby singles match, originally set for 6:00PM ET on 14 July 2026, with the market currently implying a 48% chance that Mushika advances. The contest is part of the W75 Granby tournament, a key stepping event for players aiming to climb the women’s professional rankings.

Historical ITF W75 matches in North America show a slight home-court advantage for Canadian players, yet Mushika, a Japanese competitor, has won 54% of her last 12 outdoor hard-court matches, while Brace holds a 49% win rate on similar surfaces over the same period. On Polymarket, this 48% implied probability translates to roughly 2.08 decimal odds, whereas Kalshi lists the same outcome at $0.48 per contract, reflecting its cash-settlement model. Betfair and Smarkets typically charge 2–5% commission on winnings, contrasting with Polymarket’s zero-fee structure for most users, though Kalshi requires full KYC verification for all traders.

Traders should monitor the official ITF Granby schedule for any postponement notices, as matches delayed beyond seven days without a result trigger a 50-50 settlement. The tournament’s weather forecast for Granby, Quebec, shows a 30% chance of rain on 15 July, which could impact surface conditions if the match is rescheduled. According to ITF’s latest update, no player withdrawals have been confirmed, but surface hardness and humidity levels remain critical variables for performance on outdoor hard courts [1].
