Market context
Billy Ray Goff faces Ty Miller in a welterweight prelim at UFC Fight Night, and the market’s 0% YES implies the crowd is treating it as a near-certainty that the posted side is not the winner. In programmatic terms, this is a classic live-event binary with a hard settlement source: the official UFC result, so any bot, scraper or conditional-order workflow should key off the final bout announcement rather than third-party scorecards or sportsbook lines.[4][5]
The comparable-case frame is straightforward: Goff has the stronger power profile, with 7 KO/TKO wins from 9 career victories, while Miller is unbeaten at 7-0 with a broader decision mix and one no contest on his ledger.[2][4] UFC Stats shows Goff lands 7.16 significant strikes per minute to Miller’s 7.51, but Goff’s accuracy is higher and his takedown defence is better, which matters if a market model is trying to distinguish a volatile finish from a slower points win.[4] That combination usually produces a wider pricing band than a pure 0% print unless there is a late lineup or injury edge.
The main catalysts to watch are official bout status, weigh-in clearance, and any late-card reshuffle before the UFC’s settlement window closes. Because the market also pays out 50-50 if the fight is cancelled, postponed beyond the cutoff, or ruled no contest, a production bot should monitor UFC bout announcements and event-day cancellation notes, then suppress stale orders if the matchup is removed from the card.[4] If you are automating exposure, the useful trigger is not pre-fight media noise but the final UFC result feed, since even a technical draw or no contest flips the outcome away from either fighter.[4]

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
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 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%.
