National Bank Open: Raphael Collignon vs Alexei Popyrin

Platform comparison

Market context

Raphael Collignon is due to face Alexei Popyrin in the National Bank Open, and the market’s 60% implied probability for Collignon tracks a narrow but real edge rather than a commanding favourite. The pair already met on grass in Halle in June, where Collignon won 6-4, 6-2, so the current price is being read against a live head-to-head that favours the Belgian 1-0.[3][4][12]

That earlier result matters because it showed Collignon handling Popyrin’s power game well on a fast surface, while also underlining how volatile this kind of matchup can be in ATP main draws. Collignon has also posted a stronger recent win rate over the last 52 weeks, with one source putting him at 46-23, while comparative season data show Popyrin with more losses than wins in 2026 to date.[1][2] At the same time, Popyrin’s higher career ceiling and deeper tour experience keep the market from drifting into a one-sided price, especially in a best-of-three hard-court setting where a few service games can swing the outcome quickly.[7][16]

For traders, the key catalysts are straightforward: confirmation that the match starts on schedule, any late withdrawal or walkover, and whether the tournament order of play changes before the settlement window closes. Because this market resolves to 50-50 if the match is not played, is tied, or is delayed beyond seven days without a winner, the event risk is as important as the tennis itself. On-chain, the main practical factor is USDC liquidity around the contract, while broader BTC and ETH moves mainly matter if they shift overall risk appetite and exchange funding conditions rather than this specific match’s fundamentals.

Methodology

This page reads National Bank Open: Raphael Collignon vs Alexei Popyrin on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

UK Frequently Asked Questions

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

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%.
