Market context
Alexis Galarneau’s match with Vit Kopriva at the Canadian Open is live on the tournament’s results page, but the crowd has priced a **0% YES** chance on Galarneau advancing, which is far below the broader market view implied by sportsbook-style listings. Flashscore shows Kopriva as the better-ranked player at ATP No. 70 against Galarneau at No. 167, while tennis-specific preview pages still frame the matchup as one with no prior head-to-head record, so there is no direct history to anchor the price. [6][7][13]
Comparable-case data points do not support a clean read from rank alone. Third-party tennis models and preview sites vary sharply: one head-to-head page puts Galarneau’s hard-court and 2026 win rates ahead of Kopriva’s, while another assigns Kopriva the clear edge at about 79% to win, highlighting how disagreement over recent form can swamp ranking gaps in lower-profile ATP matches. That kind of divergence matters for prediction markets because a zero-cent “YES” can reflect thin participation or stale pricing as much as a genuine view that the underdog has no path. [5][13][14]
The key catalysts are straightforward: whether the match actually starts, whether there is any official schedule change, and whether either player withdraws before first serve. The National Bank Open results page currently shows no completed match statistics, which is consistent with a fixture that has not yet produced a settled result, and the market’s resolution rules also mean a late cancellation or delay beyond seven days would push it to 50-50 rather than a win for either side.

Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
