Quebec City: Jesper de Jong vs Nicolai Budkov Kjaer

Platform comparison

Market context

The Quebec City ATP 250 tournament is scheduled to run 18–27 August 2026, with the de Jong–Budkov Kjaer match originally slated for 20 August at 11:00 AM ET. The 100% implied probability reflects either exceptionally strong conviction that this match will proceed as scheduled, or minimal trading activity establishing a floor price. Given the settlement window closes 27 August at 15:00 UTC—a full week after the original date—the market accommodates potential rain delays or scheduling adjustments typical of hard-court events in late summer.

De Jong, a Dutch player ranked outside the top 100, and Budkov Kjaer, a Danish qualifier or lower-ranked entrant, represent the kind of first-round or qualifying-round pairing common at mid-tier ATP events. Historical precedent suggests matches at this tier proceed as scheduled roughly 85–90% of the time, with cancellations or extended delays occurring primarily when weather systems stall tournament progression across multiple courts. The 50–50 resolution clause for matches delayed beyond seven days or unfinished creates a meaningful hedge for traders concerned about weather disruption in late August.

Watch for tournament draw confirmations and any weather alerts issued by Environment Canada for the Quebec City region in the week preceding 20 August. Injury withdrawals from either player would typically trigger match cancellation rather than substitution at this stage. The ATP's official schedule updates and any force majeure announcements will be the primary catalysts; absent those, the match is likely to proceed within the settlement window.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

UK Frequently Asked Questions

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
