Pronóstico: National Bank Open: Thiago Agustin Tirante vs Taylor Fritz

Platform comparison

Market context

Polymarket is pricing the contract as a near-certainty on **Taylor Fritz**, with the crowd-implied probability at **100% YES** for the Fritz side. On Polymarket, that means users are holding USDC exposure on Polygon through conditional tokens, so the payoff is tied to the official match outcome rather than a straight sportsbook line.

The historical read also leans heavily Fritz’s way. He enters as the higher-ranked player, listed at **ATP No. 9** against Tirante at **No. 65**, and the pair have **no prior head-to-head** record, which is common in early-round ATP matches but still leaves the market anchored to overall tour-level strength rather than matchup history.[17][12] Fritz’s recent-season numbers are materially stronger too: he is reported with a 2026 win rate in the mid-60s to low-70s depending on source, while Tirante’s sits lower, and Fritz’s serve profile is notably more powerful, with far more aces and a higher first-serve success rate.[1][2][6]

For traders, the key catalysts are simple: whether the match is played as scheduled, whether the ATP/organisers keep the court assignment and start time intact, and whether any late withdrawal, postponement or retirement changes the settlement path. Flashscore and tournament pages currently list the match for 5 August 2026, which supports the live status of the market rather than a cancellation scenario.[8][13][17] Because this market resolves to **50-50** if the match is not played at all, or is delayed beyond the seven-day window without a winner, schedule changes matter just as much as form.

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.
