Pronóstico: Granby: Nicolas Arseneault vs Andres Martin

Platform comparison

Market context

The Granby ATP Challenger match between Nicolas Arseneault and Andres Martin is set for 10:00 AM ET on 13 July 2026 in Canada, with Polymarket pricing the contract for Arseneault to advance at a 25% implied probability in USDC on Polygon. This low valuation reflects Arseneault’s current ATP ranking of 674 and his recent 2–0 loss to Henry Searle in Little Rock, contrasting with Martin’s established presence in higher-tier events despite a noted nine-match losing streak in recent form [2][3][5].

Historically, Challenger-level matches featuring players with similar career win totals but divergent recent trajectories often see early market prices correct sharply once draw specifics and surface conditions are confirmed; comparable cases from 2024–2025 Granby events show that underdogs with lower rankings but fresher match legs can outperform initial 20–30% probabilities when opponents carry extended losing streaks [1][3]. The 25% price here aligns with that pattern, suggesting traders are pricing in Martin’s streak as a decisive negative factor.

Traders should monitor the official ATP draw confirmation and any withdrawal notices before the 10:00 AM ET start, as a pre-match withdrawal would resolve the market to a fair 50–50 split per on-chain conditional token rules [4]. The primary catalyst is the finalised court assignment and any late fitness updates from either player’s team, with the ATP Tour’s live scores page serving as the authoritative source for real-time status changes [3].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Qué Es, which mirrors the Polymarket order book directly.

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.
