Granby: Yuta Shimizu vs Jay Dylan Friend

Platform comparison

Market context

Yuta Shimizu faces Jay Dylan Friend in a Granby tournament match originally scheduled for 13 July 2026. The settlement window closes on 20 July, allowing a seven-day window for the match to conclude before resolution triggers the tie-break clause. The 100% implied probability reflects either exceptionally strong conviction about one player's advancement or minimal market liquidity at present.

Shimizu and Friend operate at different tiers of professional tennis, which typically determines match outcomes more reliably than head-to-head records in lower-tier events. Shimizu's recent form and ranking position relative to Friend's trajectory matter considerably; players ranked outside the top 200 often face inconsistent scheduling and withdrawal patterns that can affect tournament completion rates. Historical precedent from Granby events shows that matches at this level occasionally fail to complete due to injury retirements or scheduling conflicts, though outright cancellations remain uncommon once draws are finalised.

Traders should monitor official ATP or ITF announcements regarding either player's fitness status in the week leading to 13 July, as late withdrawals are more frequent at secondary tour events than majors. Weather disruptions at the Granby venue could delay play beyond the seven-day threshold, triggering the 50-50 resolution. Any news of suspension, injury, or unexpected scheduling changes from the tournament organisers would shift the current certainty meaningfully. The settlement window's tight margin—only seven days from the scheduled date—makes completion timing a material factor rather than a peripheral detail.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
