Market context
Polymarket has this **More Markets** contract at **0% YES** today, so the market is effectively assigning no value to any qualifying additional market resolving before the settlement window closes at 16:00 UTC. On-chain, that means USDC on Polygon is still being priced through conditional tokens, but traders are treating the set-up as a dead contract unless a specific ancillary market is listed and settles in time.
The real-world anchor is AC Horsens v Brøndby in the Danish Superliga, due at 16:00 UTC in Horsens, and the comparable read-through is that Brøndby usually carries the stronger market expectation. ESPN lists Brøndby at -145 on the match, while FotMob shows Brøndby ahead in the head-to-head ledger, 10 wins to Horsens’ 8, with 5 draws. That combination matters for “more markets” contracts because the payout usually depends less on the final scoreline itself and more on whether the exchange, league, or event host adds eligible sub-markets before expiry.
The main catalysts are administrative rather than sporting: a late market listing, a rules clarification, or a change to the settlement source. Traders should watch for new Polymarket market creation, any event metadata updates, and whether the match proceeds on schedule at Hybel Arena/CASA Arena without postponement, since timing is central when the window ends the same day. Recent previews and live listings from Tipsbladet, BBC Sport and FotMob all place the fixture on 9 August at 16:00 UTC, but they do not indicate any specific extra-market dependency beyond the match itself.[9][11][3]
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
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'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%.
