Granby: Sasha Rozin vs Keegan Rice

Platform comparison

Market context

The underlying event is the Granby tennis match between Sasha Rozin and Keegan Rice, originally scheduled for 14 July 2026 at 2:30PM ET. The market currently shows a 0% implied probability for Sasha Rozin advancing, suggesting the crowd expects Keegan Rice to win or the match to be unresolved in Rozin’s favour.

Historical data from similar junior-level tennis prediction markets on Robinhood shows that when one player holds a clear price advantage (here, Rice at 59¢ versus Rozin’s 42¢), the lower-priced outcome rarely reverses unless the match is delayed or cancelled [1]. In past Granby tournaments, matches postponed beyond seven days without a winner defaulted to a 50-50 resolution, but outright cancellations before play were rare, keeping directional bets stable once odds formed.

Traders should monitor the official tournament schedule for any delay notices or retirement announcements, as these directly trigger the 50-50 settlement clause. A recent update from Robinhood confirms that event resolution typically occurs within one hour of the match ending, meaning liquidity will shift rapidly once the result is confirmed [1]. For users on polymarket-klarna.co.uk, the depth of this book depends on seamless on-ramps via Klarna and SEPA, as withdrawal friction in USDC rails can dampen participation when odds are skewed.
