Hagen: Lorenzo Giustino vs Jerome Kym

Platform comparison

Market context

Polymarket’s contract is showing **0% YES**, so the market is effectively pricing no chance of Lorenzo Giustino advancing against Jerome Kym on the current order book. On Polymarket, buyers pay in **USDC** on **Polygon**, and the outcome is represented through **conditional tokens**, so the live price is the market’s view of who is most likely to advance rather than a direct forecast of the scoreline.

The 0% reading is best read against the usual limits of thin tennis markets: when a contract is near the floor, the price can reflect low activity as much as strong conviction. There is no previous head-to-head record listed for the pair, and both players are relatively close in current ATP ranking, with Giustino around No. 198 and Kym around No. 205 in live listings, so the market is not being driven by a large ranking gap alone.[3][4][5] Kym has also been in stronger recent form in the surrounding event pages, including a straight-sets win over Matej Dodig, which helps explain why traders may have little appetite for YES at this stage.[2][8]

For settlement, the key issue is not just who is favoured but whether the match is actually completed inside the window. Current live listings place the fixture in Hagen on 7 August 2026 at 12:00 local time, and Polymarket’s rules mean a cancelled match, a tie, or a delay beyond seven days without a winner would resolve to 50-50 rather than a player result.[1][9] Traders should watch ATP Challenger scheduling pages and live score feeds for court changes, postponements, or retirement scenarios, because once a match starts but is unfinished, the advance decision can still determine settlement.[4][14]

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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%.
