Canadian Open, Qualification: Hugo Gaston vs Duncan Chan

Platform comparison

Market context

Hugo Gaston and Duncan Chan were still in play in Montréal, with the qualifying match listed on the National Bank Open site and live scoring pages showing an outdoor hard-court contest at Centre Court.[2][7][13] The crowd-implied probability at 0% YES suggests the market is already pricing in no remaining path to a normal win resolution, which fits a market that can only settle 50-50 if the match is abandoned, tied or delayed beyond the seven-day window.

The comparison frame is straightforward: Gaston is the established ATP-level player, ranked around No. 90, while Chan is far lower in the rankings at around No. 601.[2][8] In similar qualifier match-ups, rank gap tends to matter most when the favourite is still active and the match is completed; but if a market has already moved to zero, traders usually read it through completion risk rather than pure tennis ability. Head-to-head data also appears limited or absent, so there is little historical basis here beyond the ranking mismatch and the live contest itself.[10][15]

What matters now is whether the event is formally completed and published as a result, or whether any late interruption changes settlement. The tournament’s own match page and third-party scoreboards are the key dependencies to watch for the final outcome state, especially if there is a suspension, retirement or scheduling slip before the settlement window closes.[2][7][13] If the match is recorded as finished, the market should resolve to the advancing player; if not, the 50-50 clause becomes the relevant fallback.[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 Prediction Today, which mirrors the Polymarket order book directly.

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

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 Prediction Today trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
