Swedish Open, Qualification: Francesco Passaro vs Martin Krumich

Platform comparison

Market context

Francesco Passaro faces Martin Krumich in the final Swedish Open qualification match at Bastad, with the on-chain contract on Polymarket currently pricing Passaro’s advancement at 0% YES despite him being the fourth seed in qualifying. This near-zero pricing contradicts traditional bookmaker odds, where Passaro holds a clear advantage at +119 for a 2–0 win, suggesting the market is either mispriced or awaiting a critical off-chain event like a withdrawal or cancellation that would trigger the 50-50 settlement clause.

Historical precedents in ATP qualification markets show that 0% prices often precede either a late withdrawal by the favoured player or a technical error in the conditional token logic, as seen in similar low-stakes European tour events where liquidity dries up before the match begins. In past cases, such extreme pricing resolved quickly once the match commenced or was confirmed as played, with the probability snapping to reflect the actual head-to-head advantage rather than remaining at zero.

Traders should monitor the official ATP Bastad schedule and real-time updates from Flashscore for any delay notices or player status changes, as a delay beyond seven days without a winner would force the 50-50 resolution. SportyTrader notes Passaro is nearly 100% likely to advance based on current form, so the 0% market price likely reflects a liquidity gap or unconfirmed withdrawal rather than genuine doubt about his ability to win the match on court.

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.

FAQ

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

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

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
