Arsenal FC vs. Real Betis Seville - More Markets

Platform comparison

Market context

Arsenal play Real Betis Seville in a club friendly, and Polymarket is currently pricing the relevant contract at **0% YES**, which means the market is treating the named “more markets” condition as essentially shut off despite the fixture itself being scheduled. Because this is a Polymarket sports market, settlement runs through USDC on Polygon via conditional tokens, so traders are effectively bidding on the contract’s resolution rules rather than the abstract result of the match.

That 0% reading sits well below the broader pre-match view elsewhere, where Arsenal are still generally framed as favourites. Sports Mole gives Arsenal a **55.25%** win probability, with Betis on **20.85%** and the draw at **23.9%**[19]. Other previews also lean Arsenal, with scoreline calls such as **2-1** or **2-0** appearing repeatedly, which suggests the market’s current zero-price is more about the specific Polymarket sub-market structure than a consensus that Betis are likely to dominate[2][5][8]. In comparable friendly markets, line-ups and rotation usually matter more than season-long quality, because pre-season substitutions can swing individual side markets quickly.

A trader should watch team-sheet announcements, late injury or travel updates, and whether either side confirms a heavily rotated XI, because those are the main dependencies that can move a friendly-market price late. Arsenal-focused previews note the fixture is part of pre-season sharpness work, with younger players and fringe names expected to feature, which increases variance versus a competitive league match[8]. On the Polymarket side, the contract remains open if postponed until the game is completed, so any delay or schedule change would matter for timing as much as for outcome[1].

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.

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%.
