Market context
Gabriele Piraino faces Lorenzo Comino in an ITF Men's 25k tournament at Lesa, scheduled for 19 August 2026. The market currently shows 0% probability for Piraino's advancement on Polymarket, with settlement occurring by 26 August. This pricing reflects either minimal liquidity or strong conviction amongst traders that Comino will prevail. On Polygon, the conditional token structure means positions settle in USDC once the match outcome is determined and reported to the oracle.
ITF M25 events sit at the lower tier of professional tennis, where seeding and ranking disparities often prove decisive. Historical resolution patterns for similar low-level ITF matches show that markets frequently misprice unknowns due to sparse trading volume and limited public information on player form. A 0% probability on an event with genuine uncertainty—particularly when neither player commands significant media coverage—typically signals shallow order books rather than certainty. Comparable M25 markets have shifted dramatically once match day approaches and traders with direct knowledge enter positions.
Traders should monitor the official ITF schedule for any postponements or venue changes, which would trigger the seven-day delay clause leading to 50-50 resolution. Player withdrawal announcements, injury reports, or late-draw confirmations rarely surface in mainstream tennis news but occasionally appear on ITF official channels. The settlement window's tight margin—ending just hours after the scheduled match time—leaves minimal room for dispute resolution, making early confirmation of the result critical for position holders.
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
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
