Granby: Aleksandar Vukic vs Nicolas Arseneault

Platform comparison

Market context

The Granby Challenger match between Aleksandar Vukic and Nicolas Arseneault, originally set for 15 July 2026, has already seen Vukic advance, leaving the Polymarket contract for his victory at a near-certain 100% YES. On Polygon, this USDC-backed position trades as a conditional token reflecting an outcome that has effectively occurred, with the settlement window closing in July 2026 only to formalise the result.

Historically, prediction markets for tennis matches where one player has already won resolve to 100% once the result is confirmed, mirroring cases like the 2024 ATP Challenger events where early match completions locked prices instantly. In such instances, the conditional token’s value aligns perfectly with the real-world outcome, eliminating arbitrage opportunities and confirming the market’s efficiency in capturing known results.

Traders should monitor the official Granby tournament schedule for any administrative delays or cancellations that might trigger the 50-50 resolution clause, though Vukic’s advancement is already documented. Tennis Tonic’s pre-match analysis, which picked Vukic to win in two sets at odds of 1.137, aligns with the current market pricing, reinforcing the certainty of his victory [1]. No further announcements are expected before the settlement date, as the match outcome is final.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
