National Bank Open: Ekaterina Alexandrova vs Elina Svitolina

Platform comparison

Market context

Ekaterina Alexandrova and Elina Svitolina are set for a National Bank Open quarter-final meeting, with the market currently giving Alexandrova only a **17%** chance despite the fixture being live. The latest pre-match pricing and model views still lean towards Svitolina, with several outlets listing her as the clear favourite and projecting a straight-sets win, which keeps the crowd figure on the low side for Alexandrova.[1][3][5][17]

That probability fits the broader record of this matchup: Svitolina has generally been rated ahead on hard courts, including in head-to-head and Elo-style comparisons, and the recent preview consensus also tilts her way.[8][19] Comparable tournament pricing has treated Alexandrova as the outsider in this pairing, so a sub-20% market price is consistent with a side that needs either an upset profile or a notable shift in form to re-rate materially.[3][12][15]

For traders, the main catalysts are simple: whether the match stays on the published schedule, whether either player is withdrawn late, and whether play actually starts without weather or court-order disruption. The market rules also matter, because a cancellation before play or a delay beyond seven days from the scheduled date would settle 50-50, so any change to the tournament’s scheduling or completion status is more important here than in a standard winner market.[2][11]

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 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.

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.

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%.
