Market context
Jacob Fearnley and Alexis Galarneau are scheduled to meet in the opening round of the Quebec City ATP 250 tournament on 20 August 2026. The market currently prices this contract at 100% YES on Polymarket's USDC/Polygon infrastructure, indicating conditional tokens have collapsed entirely toward Fearnley advancement. This extreme pricing reflects either overwhelming confidence in a Fearnley victory or, more likely given the 100% reading, a thin liquidity position where few traders have committed capital to back Galarneau's chances at any price point.
Fearnley, a British player ranked in the 80s, has shown steady improvement on the ATP circuit with occasional deep runs in lower-tier events. Galarneau, a Canadian qualifier or main-draw entrant depending on final draw confirmation, typically competes in Challenger events and would represent a significant step up in competition. Historical precedent suggests home-nation players at ATP 250 events often receive favourable seeding and scheduling, though this cuts both ways—Galarneau's Canadian status may energise crowd support but rarely translates to meaningful odds shifts in professional markets. The 100% pricing appears disconnected from typical match uncertainty; comparable first-round ATP 250 matchups between ranked players and lower-ranked opponents usually settle between 65–80% for the higher-ranked player.
Traders should monitor official ATP draw confirmation (typically released 10–14 days before the event), any late withdrawals or injury announcements, and weather forecasts for Quebec City in mid-August. The settlement window closes 28 August 2026, providing an eight-day buffer beyond the scheduled date for match completion or resolution under the 50-50 tie-break clause.
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 PolyGram, 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
- 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.
- 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.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
