Market context
Norwich City and West Bromwich Albion will meet on 15 August in the opening fixture of the 2024–25 EFL Championship season. Polymarket currently prices this "More Markets" contract at 0% YES, reflecting minimal trading activity or settlement ambiguity around supplementary betting options that may emerge for this fixture. The settlement window closes at 14:00 BST on match day, giving traders a narrow window to react once additional markets are formally listed on-chain via USDC-denominated conditional tokens on Polygon.
Championship opening-day fixtures historically attract fragmented liquidity across secondary market clusters. Norwich finished fifth last season and retained most of their promotion-chasing squad, whilst West Brom secured automatic promotion as runners-up and enter as favourites. Previous seasons show that "More Markets" contracts—typically covering goal scorer combinations, half-time/full-time permutations, or card-based outcomes—settle YES when Polymarket expands its offering beyond standard 1X2 and over/under lines. The 0% pricing suggests either minimal expectation of expansion or insufficient trader conviction to establish a position ahead of the settlement deadline.
Traders should monitor Polymarket's official announcements and the EFL fixture calendar for any last-minute postponements, which would trigger settlement disputes. Team news regarding injuries or suspensions typically emerges 48 hours pre-match; Norwich's recent squad depth and West Brom's settled roster reduce postponement risk. The tight settlement window means conditional token holders cannot rely on post-match clarity—any ambiguity in market definitions must resolve before 14:00 BST, making early clarity from the platform essential.

Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
UK Frequently Asked Questions

- Is Polymarket legal in the UK?
- Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction.
