Granby: Sasha Rozin vs Keegan Rice

Platform comparison

Market context

On 14 July 2026, Sasha Rozin and Keegan Rice will face off in the round of 16 at the Granby Challenger, a men’s hard-court tournament in Quebec. A YES share in this market pays out if the named player wins the match and advances; a NO share pays if they lose or the match is cancelled under the settlement rules. With the crowd-implied probability for Sasha Rozin at 0% YES, the market currently treats his advancement as virtually impossible, despite him entering with two consecutive 2–0 wins.

Historically, such extreme odds in Challenger tennis often signal either a severe injury, a withdrawal, or a mismatch in form that bookmakers have already priced in. Comparable cases from 2024–2025 show that when a player’s probability drops below 1% before a match, it usually reflects confirmed absence rather than pure performance doubt, as live betting markets rarely leave such gaps unless the event is effectively off the table.

Traders should monitor official tournament updates for any withdrawal notices or schedule changes, as Granby’s draw can shift quickly due to weather or player availability. The ATP Challenger Tour’s official site and Granby’s tournament page are the primary sources for such announcements, with recent coverage noting that several Challengers in July 2026 have seen mid-week draw adjustments due to rain delays [1]. If the match is delayed beyond seven days or not played, the market resolves to 50–50, adding a binary contingency to the usual win/loss outcome.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
