Swedish Open, Qualification: Francesco Passaro vs Martin Krumich

Platform comparison

Market context

Francesco Passaro faces Martin Krumich in the Swedish Open qualification at Court 1, Bastad, with the match scheduled to begin at 09:00 UTC on 13 July 2026[1][10]. The crowd-implied probability of Passaro advancing sits at 0% YES, a stark divergence from platforms like Kalshi, which resolves unstarted matches to a fair price rather than locking in zero odds[4]. While Betfair and Smarkets typically display decimal odds reflecting this uncertainty, Polymarket’s binary probability format here suggests a near-total lack of confidence in the Italian, despite both players holding equal career win records according to historical data[3].

Historical qualification matches in Bastad often see volatility when players have recent form fluctuations, as seen with Passaro’s mixed results in early July, including a defeat to Enrico Dalla Valle before a win against Pietro Orlando Fellin[6]. Comparable cases show that 0% implied probabilities on unplayed matches frequently correct once the ball is in play, particularly when head-to-head records are balanced. Traders comparing books should note that Kalshi’s fair-price settlement for non-starts contrasts sharply with Polymarket’s current pricing, where the market assumes a forfeit or pre-match withdrawal before play commences[4].

Key catalysts include the official start confirmation at 09:00 UTC and any withdrawal announcements prior to the first serve, which would trigger settlement rules[1]. Traders monitoring Kalshi versus Polymarket must watch for the ball-in-play signal, as Kalshi resolves unstarted matches to fair value while Polymarket’s 0% implies a definitive pre-match outcome[4]. No recent news indicates a withdrawal, but the absence of live odds on major books suggests the market is awaiting the match to begin before adjusting probabilities[5].
