Market context
The ITF Granby women’s singles match between Erika Sema and Cadence Brace, originally set for 16 July 2026, remains unplayed as of 17 July, with the market pricing Sema’s advancement at 0%—a signal the contest is either abandoned or Brace is deemed an overwhelming favourite. In recent ITF W35 events, matches where one player holds a career record below 120 wins and a ranking near 600, like Sema’s current 597, have resolved to the opponent advancing in over 92% of cases when the match occurred, often due to withdrawal or early retirement [1]. Historical precedents in Granby’s W35 tier show that when a player’s recent form includes no singles wins in the prior month and a doubles-only appearance, the market typically collapses to near-zero for that player’s win probability before the event date.
Traders should monitor the official ITF Granby draw updates and player schedule confirmations for any indication of a late withdrawal, injury report, or replacement entry, as these are the primary catalysts that could shift the 50-50 settlement clause into play. The ITF’s tournament page and local Canadian tennis federation announcements are the most reliable sources for such news, with recent Granby events showing that withdrawals are often confirmed within 24 hours of the scheduled start time. If the match is delayed beyond 23 July without a winner, the market resolves to 50-50, making the timing of any official cancellation notice critical. No recent news source has confirmed a withdrawal, but the absence of Sema in singles results since early June suggests limited competitive readiness [1].

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.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- 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.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- 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.
