1. FC Cologne vs. Real Sociedad San Sebastian - More Markets

Platform comparison

Market context

1. FC Köln were due to face Real Sociedad in a summer friendly at the RheinEnergieStadion, with the clubs also scheduled for a closed-door match the night before. In a programme like this, a **96% YES** crowd price on “More markets” is consistent with a very high chance that bookmakers, exchanges, or the organiser will publish extra derivatives around the fixture before settlement, rather than a pure match-result view.[4][16]

The cleanest historical frame is that these sides have met before in Europe, with Real Sociedad taking the only prior knockout tie in 1988/89 and Köln’s own club history noting the Spanish side managed the decisive late goals in that series.[6][7] For a power user running this market through a bot or conditional-order stack, that background matters less than the event structure: friendlies typically generate multiple listed side-markets, and a second match in 24 hours usually increases the odds of extra props, lineups, or live betting menus being posted. That makes “More markets” easier to model as an availability-and-listing problem than as a football forecasting problem.[4][7]

The main catalysts to monitor are official squad announcements, confirmation of whether the closed-door game is treated as a separate listing, and any schedule changes around kick-off time or venue details.[4][16] If the organiser publishes the match as a standard club friendly with full markets, traders can watch for totals, both-teams-to-score, and half-time derivatives; if coverage is thin or line-ups are heavily rotated, market creation can still occur but with narrower scope and weaker liquidity. Recent live listings already show the fixture as a club friendly at the RheinEnergieStadion, which is the practical trigger most automated setups would use for ingestion and market expansion.[1][3][12]

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 Polymarket Bot UK, 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

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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%.
