Granby: Aleksandar Vukic vs Alexis Galarneau

Platform comparison

Market context

The Granby Challenger match between Aleksandar Vukic and Alexis Galarneau, originally set for 17 July 2026, has already concluded with Vukic dominating Galarneau 2–0 in sets, securing a 15–0 lead in the first set and 7–6 in the second before the match ended [1]. On Polymarket, this outcome is reflected in the contract pricing at 100% YES for Vukic advancing, as the on-chain conditional tokens on Polygon have effectively locked in the result with USDC settlement now certain [3].

Historically, prediction markets for tennis matches that conclude before the settlement window close resolve immediately once the governing body confirms the winner, mirroring how earlier ATP Challenger contracts settled within hours of match completion rather than waiting for the official deadline [3]. In cases where a match is abandoned mid-set, markets default to 50–50, but here the full two-set victory eliminates any ambiguity, aligning the crowd-implied probability with the factual result.

Traders should monitor the official ATP Challenger Granby draw update for confirmation of Vukic’s next-round placement, as this will trigger the final settlement of the contract [2]. No further catalysts are expected, given the match’s completion; the only dependency is the event organizer’s formal validation, which typically occurs within 24 hours of the final point. With the result confirmed and the market at 100%, the on-chain mechanics on Polygon will execute the USDC payout automatically once the settlement window closes on 24 July 2026.

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.
