National Bank Open: Raphael Collignon vs Alexei Popyrin

Platform comparison

Market context

Raphael Collignon’s meeting with Alexei Popyrin at the National Bank Open comes with Collignon priced as the likelier winner, and the crowd’s 60% yes reflects the same broad split seen in the pair’s recent form. Collignon already beat Popyrin on grass in Halle in June, winning 6-4, 6-2, so there is a direct recent head-to-head that leans his way[1][3][11]. The underlying records also point in the same direction: one source shows Collignon at 36-14 this season versus Popyrin’s 10-19, while another places Collignon’s last-52-weeks mark at 46-23[1][2]. That gap helps explain why the market is not treating this as close to a coin flip, despite Popyrin’s higher profile and stronger historical standing on tour[6][12].

For traders, the main catalysts are simple: whether both players are confirmed in the draw and on schedule, and whether either side enters with a late fitness or withdrawal issue that could alter the market before the August 6 start time. Collignon’s recent edge is strongest against lower-ranked opposition, having won 19 of 21 matches against non-top-100 players this season, while Popyrin has only managed back-to-back main-draw wins three times all year[1]. If the match is delayed past the settlement rules, or if it is not completed after starting, the payout mechanics become more important than pre-match form, because unresolved outcomes can revert the market to 50-50 rather than either player[1].

UK Frequently Asked Questions

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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%.
