Market context
Iva Jovic faces Alina Korneeva in the National Bank Open, with the market’s 0% yes price implying the board is treating the outcome as effectively unresolved rather than strongly one-sided. The main factual frame is that this is a first tour-level meeting, so there is no head-to-head history to lean on, and the two players arrive with broadly comparable 2026 hard-court records despite very different rankings and reputations.[2][3][15]
Jovic is the higher-ranked player at WTA 16, while Korneeva is listed around WTA 89, but season stats suggest the gap is narrower on court than in the rankings column.[1][15] One dataset has Jovic at 31–15 for 2026 versus Korneeva at 4–3, while another lists hard-court records of 16–7 and 15–5 respectively; both point to competent form from each side, with Jovic carrying the stronger overall body of work and Korneeva showing a solid conversion on return and break-point chances.[2][3][10]
For traders, the key catalysts are basic availability and whether the match is actually played on schedule, because the market can settle 50-50 if it is cancelled, tied, or delayed beyond seven days without a winner.[Market description] The practical watch-items are the confirmed order of play, any late withdrawals, and whether either player is forced into a reshuffled schedule after the event’s next round; the live match pages already show the pairing as pending, so pre-match movement would likely come from official tournament updates rather than from any prior rivalry angle.[6][8][15]

UK Frequently Asked Questions
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- 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.
- 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%.
