Swedish Open, Qualification: Francesco Passaro vs Martin Krumich

Platform comparison

Market context

Francesco Passaro faces Martin Krumich in the Swedish Open qualifying round at Court 1 in Båstad, Sweden, on a clay surface scheduled for 09:00 UTC on 13 July 2026[1][10]. The market currently implies a 0% probability that Passaro advances, a stark signal often seen in pre-match liquidity for lower-tier qualifiers where one player is a significant favourite or where data gaps distort pricing[2]. Historically, such extreme odds in ATP qualifying on clay frequently resolve to the favourite once the match begins, as early market inefficiencies in these tiers are corrected by live trading once serve metrics and first-set performance become visible[2].

Traders evaluating this programmatically should monitor the official ATP start-time feed and live score APIs for any delay beyond the 7-day settlement window, which would trigger a 50-50 resolution[7]. Key catalysts include Passaro’s career earnings of $1,452,403 and his head-to-head record against Krumich, which remains a critical dependency for algorithmic models assessing win probability[5][8]. Watch for real-time updates on court conditions and player availability via live score services, as clay surface performance in Båstad heavily influences serve-break dynamics and can shift odds rapidly once the match is underway[1][6].

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
