Grodzisk Mazowiecki: Andrea Guerrieri vs Daniil Glinka

Platform comparison

Market context

Polymarket prices this Guerrieri-Glinka contract at **48% YES** today, which is close to a coin flip in USDC terms on Polygon. On-chain, the market is just a conditional token position: if Andrea Guerrieri advances, the YES side pays; if Daniil Glinka advances, it does not, and if the match is not completed within the settlement rules the contract can fall back to 50-50.

That near-even level is consistent with a match where the market has not built in a strong separation between the players. Public tennis listings put Glinka higher in the ATP rankings than Guerrieri, at roughly No. 169 versus No. 215, but the pair are also shown on the same indoor hard-court challenger draw in Grodzisk Mazowiecki, and preview sites describe this as their first professional head-to-head. Guerrieri is priced only marginally behind in some third-party previews, which helps explain why the market is not far from parity.

For traders, the key catalysts are straightforward: whether the match starts on schedule, whether the draw and court order hold, and whether either player retires or the fixture is postponed. Sofascore lists the start time for 8 August at 09:00 UTC on Central Court, while other listings show 11:00 local, so timing and live completion matter for settlement. If play is interrupted and no winner is determined within seven days of the scheduled date, the contract resolves 50-50 rather than to either player.

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 PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

UK Frequently Asked Questions

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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%.
