Pronóstico: National Bank Open: Nicolas Mejia vs Martin Landaluce

Platform comparison

Market context

Polymarket is pricing this contract at **100% YES**, which, on the market’s USDC-settled Polygon conditional-token structure, implies traders expect Martin Landaluce to advance against Nicolas Mejia with essentially no room left for an opposite outcome. The event is a first-round match at the National Bank Open, and the contract only settles to 50-50 if the match is not played, ends tied, or is delayed beyond the seven-day window without a winner.

That near-certain price is easy to read against the available comparison set: the pair have **no prior head-to-head**, so there is no direct matchup history to anchor a fair line[1][2][6]. The ranking gap is one obvious clue, with Landaluce listed around ATP **63-64** and Mejia around ATP **129-131** across live event pages[1][4][10]. Landaluce also carries the cleaner hard-court profile in the data shown, while Mejia’s tour-level hard-court record is notably thin, including a reported **0-3** mark in main-draw hard-court matches[1][3].

For traders, the main catalysts are not abstract form but whether the match is actually staged and completed inside the settlement rules. The tournament listing places the match in the Montreal draw, and live scoreboards indicate it was originally scheduled for 2 August, so any late withdrawal, weather hold, or schedule reshuffle is relevant because a non-played or badly delayed match can push the market to **50-50** rather than a one-sided payout[1][10][13]. Recent score pages also show both players coming in with mixed short-term results, which matters less than their final availability and the official result once play begins[12][14].

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
