National Bank Open: Alex Michelsen vs Francisco Cerundolo

Platform comparison

Market context

Alex Michelsen and Francisco Cerundolo are set to meet at the National Bank Open, with the market implying Michelsen is a strong favourite at 77%. The price makes sense as a reading of current form rather than a clean class gap: Michelsen’s year-to-date win rate is higher on the available stats, while Cerundolo has still compiled a solid season and the pair split their two previous meetings[1][3].

That head-to-head is the main historical frame. Cerundolo beat Michelsen indoors in Vienna in straight sets, but Michelsen overturned him on grass in Halle in three, so neither player has a decisive matchup edge[3][4][16]. That kind of split record often leaves hard-court pricing more sensitive to surface fit, fitness and recent workload than to any single prior result, especially when the market is already leaning hard one way[1][3].

The catalysts to watch are any late draw or schedule adjustments, plus confirmation that both players are fully available and not carrying a fitness issue from the previous round. Flashscore already lists the fixture for 5 August 2026, which suggests it is on the board, but traders still need to watch for postponement, walkover risk or a late withdrawal because this market would flip to 50-50 if the match is not completed within the settlement window’s rules[2].

UK Frequently Asked Questions

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

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%.
