UFC Fight Night: Diego Ferreira vs. Billy Quarantillo (Lightweight, Main Card)

Platform comparison

Market context

Diego Ferreira versus Billy Quarantillo is a lightweight main-card bout at UFC Fight Night in Las Vegas, and the market is effectively pricing a completed, officially recognised result rather than a delay or cancellation. Ferreira comes in with a 19-7 record and Quarantillo at 18-7, with the matchup pairing a more submission-heavy Ferreira profile against a higher-output Quarantillo style.[1][2][4]

The current 100% YES price is best read against both men’s recent skid and the lack of any obvious settlement risk in the record books. MMA Junkie noted Ferreira had lost his last two, after a finish of Mateusz Rebecki in May 2024, while Quarantillo had also dropped two straight, both by stoppage, with his last win a decision over Damon Jackson in August 2023.[7] Comparable pre-fight data points reinforce how close the bout looks on paper: Quarantillo averages more significant strikes landed per minute, but Ferreira is more efficient on defence and has the better submission threat, so a tight main-card booking is more likely to move on method than on a clear edge in record or form.[2][3][8]

For traders, the main catalysts are confirmation that the bout stays on the official UFC card, the order of the main card, and any late injury or weight-miss news that could force a cancellation or no contest before the settlement window closes. UFC-facing listings and fight previews still show the pairing as scheduled for 8 August 2026, but the practical watchlist is any final bout-sheet change, medical withdrawal, or post-weigh-in issue that could convert a straightforward result market into the 50-50 fallback.[4][6][9]

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.
