UFC Fight Night: Steven Asplund vs. Guilherme Pat (Heavyweight, Main Card)

Platform comparison

Market context

Steven Asplund meets Guilherme Pat in a heavyweight main-card fight at UFC Fight Night, and the market’s 100% crowd-implied price for Asplund is much firmer than the sportsbook range suggests. Across listed books, Asplund is generally around the -270 to -333 band, with Pat roughly +220 to +270, which points to a clear favourite but not a lock; the wider market has Asplund around the low-70s in implied win probability rather than a perfect score. [1][7][9]

That gap matters because comparable UFC moneyline markets can still reprice sharply once weigh-ins, late injury news, or camp changes surface, especially in heavyweight bouts where one punch can flip the result. Public previews also frame both men as coming in off losses, with Asplund still favoured on form and recent knockout upside while Pat is being treated more as a live underdog than a longshot. [19][14]

For traders, the main catalysts are the official bout status, any last-minute replacement, and the UFC’s final pre-fight confirmation before the August 22 settlement cutoff. The most relevant watchpoint is whether the matchup stays intact on the final card and whether either side brings a materially changed camp report, because current pricing already assumes the fight happens and reaches an official result. Kalshi’s event page also shows the contract expiring on August 22, reinforcing that postponement or cancellation would push the market towards 50-50 rather than a fighter-side settlement. [9][12]

UK Frequently Asked Questions

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

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%.
