Canadian Open, Qualification: Shintaro Mochizuki vs Dane Sweeny

Platform comparison

Market context

Shintaro Mochizuki and Dane Sweeny were due to meet in Montréal qualifying on the hard courts, but the key market move is that the match has already been listed as finished on some live result pages, with Mochizuki recorded as the winner. That is consistent with the crowd-implied 100% YES price on Mochizuki, which reflects a result that looks effectively locked in rather than a live 50-50 contest.[1][3][8]

The main framing point is that this is a close ranking match on paper, not a lopsided one: Sofascore lists Mochizuki at ATP No. 114 and Sweeny at No. 121, and tennisstats notes no prior head-to-head, which means there was little historical basis for one player to be strongly favoured before play.[1][16] On comparable pre-match pricing, independent market pages had already leaned Mochizuki, but only modestly, with one market showing him around 49% and another around 60%, underscoring that the current 100% reading is being driven by match progress or completion rather than pre-event expectations.[12][15]

For traders, the immediate catalysts are tournament-side confirmation and any official draw or scoreboard update from the National Bank Open, because settlement depends on whether the match was completed, abandoned, or later voided by delay rules. The published match listing points to Court 9 in Montréal on outdoor hard, and the tournament results page already shows a completed scoreline, so the remaining watchpoints are administrative: whether the result stands, whether any retirement or postponement note appears, and whether there is any contradiction between live data feeds and the official event record.[1][8][18]

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.

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.
