Market context
Carol Young Suh Lee and Gabriela Knutson are scheduled to play in Warsaw, and in a prediction market a **YES** share pays out if the named outcome happens, while a **NO** share pays out if it does not. In this market, the settlement is tied to which player advances, but if the match is not played, ends level, or is delayed beyond seven days without a winner, it resolves 50-50 under the market rules.
The current crowd-implied probability of **100% YES** points to an unusually one-sided market view, but the relevant sporting context is narrower than that number suggests. Public tennis listings show the fixture as a Warsaw final on 8 August 2026, with both players already placed in the same match-up, and historical head-to-head data indicates they have split their previous meetings 1-1, which is a useful reminder that the market is still anchored to a single live event rather than a season-long trend.[3][7][9][14] For newcomers, that means the price reflects the probability of the exact settlement event, not simply which player is stronger on paper.
Traders should watch for any change to the official order of play, late withdrawals, walkovers, or a completed result being recorded after a suspension, because those are the kinds of updates that can move a market from a normal win/lose settlement into a void or split outcome. The key dependency is whether the match is actually completed within the market’s seven-day window from the scheduled date, since that determines whether the contract resolves to one side or reverts to 50-50 under the stated rules.[2][14]
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
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's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- 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%.
