Market context
Islam Makhachev’s welterweight title defence against Ian Machado Garry is set, and the market’s **76%** crowd-implied chance for Makhachev reflects that the fight is still being read as a grappling-versus-range contest rather than a clean coin flip. UFC Stats lists Makhachev at 28-1 and Garry at 17-1, with Makhachev carrying the stronger takedown volume and a much higher takedown defence number, while Garry brings a reach edge and higher striking output. [8]
That probability sits in line with how comparable UFC championship match-ups have been priced when one fighter has the clearer control game and the other relies on distance management. The historical pattern in these fights is that the favourite’s price tends to hold unless the underdog can keep the bout standing for long stretches or force a low-variance decision; that is why markets often stay anchored near the wrestler-champion side even when the challenger has cleaner volume and range. [3][9]
For the next 24-48 hours, the key catalysts are any official UFC media, weigh-in notes, or late scheduling changes, because the market resolves only on the official result and would flip to 50-50 if the bout were declared a no contest, draw, or postponed beyond the cutoff. Recent reporting has also kept attention on Makhachev’s comments about Garry and on whether the bout remains framed as a title defence in Philadelphia, which matters for any last-minute card or venue updates.

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.
- 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.
- 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%.
