Market context

Iva Jovic and Magda Linette are scheduled to play at the National Bank Open, and the market resolves on who advances rather than on a completed scoreline. At a crowd-implied **94% YES**, the contract is pricing a near-certain Jovic advance, which is consistent with her having already beaten Linette in two recent hard-court meetings, including at the 2026 Hobart quarter-finals and the 2024 US Open.[2][12][13]

The historical frame also leans towards Jovic. Public H2H pages show Jovic leading the series 2-0, with the most recent meeting in Hobart going to three sets before Jovic closed it out, while her current-year hard-court win rate has been materially stronger than Linette’s on the same comparison pages.[2][11][13] That sort of gap is usually what pushes a binary advance market into the 90s, especially when the opponent has already been beaten twice on the same surface.[3][8]

For traders, the main catalysts are simple: official match start, any late schedule change, and whether the contest is completed inside the contract’s seven-day settlement window. If the match is postponed, abandoned, or not resolved by the deadline, the market can fall back to 50-50 rather than paying out on the favoured side. In practice, that makes draw risk, weather, and tournament scheduling more relevant than broader tennis form; on the crypto side, the payoff is still USDC-settled, so there is no direct BTC or ETH linkage unless wider market volatility is affecting position sizing or exchange liquidity.

Methodology

This page reads National Bank Open: Iva Jovic vs Magda Linette 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%.
