Market context
Polymarket is pricing Movistar KOI to win this best-of-three at about **66%** on USDC-settled conditional tokens on Polygon, so the market is already leaning towards KOI rather than treating this as a coin flip. The match itself is scheduled as Movistar KOI versus GIANTX in the LEC Regular Season, with settlement tied to the actual winner, while a cancellation, tie, or delay beyond seven days would push the market to 50-50.
That price fits the broader pattern from recent matchup data. KOI have generally had the stronger head-to-head record against GIANTX, with one recent series preview noting an 80% H2H win rate across the last five meetings and another model giving KOI a clear edge despite mixed short-term form[6][10]. More recent live market and preview pages also put KOI ahead on series quality and matchup experience, although GIANTX have shown they can punish slow starts and make best-of-three formats messy if draft or early map control breaks their way[1][2].
For traders, the main catalysts are straightforward: line-up confirmation, any last-minute schedule change, and whether the series starts on time, because Polymarket resolution depends on the match actually being completed under LEC conditions. Sofascore lists the match start at 17:15 UTC, which matches the listed settlement window, and any postponement or technical disruption could matter more here than in a one-off scoreboard market[12]. In practice, the most relevant watchpoints are official LEC broadcast updates, team social posts, and whether either side arrives with a stable roster or substitute announcement close to lock[2][12].

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
- 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%.
