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

Platform comparison

Market context

Diego Ferreira and Billy Quarantillo are due to meet in a lightweight bout on the main card, and the market settles on the official UFC result: a Ferreira win pays out **Diego Ferreira**, a Quarantillo win pays out **Billy Quarantillo**, and any draw, no contest, cancellation or postponement beyond the deadline would resolve to **50-50**. In prediction-market terms, a **YES share** is the contract’s positive outcome and a **NO share** is the alternative; here, the crowd-implied 100% YES reading means the market is treating one outcome as virtually certain.

The pre-fight numbers point to a fairly standard striker-versus-mixed-grappler clash. Quarantillo has tended to throw more volume, with higher significant strikes landed per minute and more takedown attempts, while Ferreira has usually been the more efficient defensive fighter and has a stronger submission profile over his career[1][2][14][19]. That is the kind of matchup where the final result can still hinge on method and judges’ scoring, even when one side looks better on paper; Ferreira’s recent odds around the mid-60% range to win, versus Quarantillo near 40%, show that pre-event pricing was not one-sided[5][8][11].

For traders, the main catalysts are straightforward: the bout must actually take place on the announced card, the UFC must complete and officially post the result, and any late change to the schedule would matter more than pre-fight statistics. Because the settlement window closes shortly after the event, the key watchpoints are the fight-week weigh-ins, any last-minute medical or commission issues, and the official bout result released by the UFC after the card concludes[5][6][9].
