National Bank Open: Thiago Agustin Tirante vs Taylor Fritz

Platform comparison

Market context

Polymarket is pricing the Thiago Agustín Tirante v Taylor Fritz contract at **100% YES** for Fritz, which is consistent with a near-certain view that the American advances in Montreal. Because this market settles on who advances rather than the exact score, a cash position here is mainly a read on match completion and winner selection, with payouts held in **USDC** on **Polygon** through Polymarket’s conditional-token structure.

That pricing sits in line with other pre-match signals. Tennis Tonic and Stats Insider both describe Fritz as the clear favourite, with pre-match moneyline odds around **1.14 to 1.18** for Fritz and roughly **4.5 to 5.5** for Tirante[1][14]. Comparable markets on exact-score outcomes also show the same shape: Fritz winning in straight sets is the dominant expectation, while Tirante-winning outcomes are priced as remote[6]. In practical terms, a 100% market price leaves little room for upset risk but also reflects that traders are effectively saying the contract’s binary event is almost fully resolved in favour of Fritz.

For a Polymarket user, the main catalysts are not form narratives but operational ones: the match status, any rescheduling, and whether the fixture is actually completed within the settlement rules. The National Bank Open match listings show the tie is on the tournament schedule, but live tennis markets can move on delayed starts, retirements, or withdrawals if the on-court outcome is not completed[3][4]. If the match is postponed, cancelled, or pushed beyond the market’s seven-day window without a winner, the contract can resolve at **50-50** under its terms, so the key watchpoint is whether the ATP and event organisers confirm play and an official result[3].

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.
