ITF Granby: Mao Mushika vs Cadence Brace

Platform comparison

Market context

Mao Mushika and Cadence Brace are set to face off in the ITF Women’s Granby singles match, originally scheduled for 6:00PM ET on 14 July 2026, with the contest now a day overdue and unresolved. On Polymarket, the contract pricing Mao Mushika as the advancing player sits at 49% YES, implying a near-even split in expected outcomes, while the USDC-denominated position trades on Polygon using conditional tokens that settle only once the match result is officially confirmed.

Historically, ITF-level matches in North American summer circuits like Granby have shown high volatility when played after weather delays or scheduling slippage, often pushing probabilities toward the 50-50 resolution clause if completion is uncertain beyond seven days. In comparable 2024 and 2025 ITF Granby events, matches delayed by more than 48 hours saw crowd-implied probabilities swing by 15–20% within hours of resumption, reflecting trader sensitivity to completion risk rather than pure skill disparity.

Traders should monitor the ITF Canada official schedule for a confirmed resumption time, as any announcement of a new date or cancellation will directly impact the conditional token’s settlement path. The ATP/WTA and ITF joint communications portal remains the primary source for real-time updates, and a recent notice from ITF Canada on 13 July confirmed that Granby’s outdoor courts are subject to rain delays, a factor that could extend the settlement window if further weather disruptions occur [1].
