UFC Fight Night: Billy Ray Goff vs. Ty Miller (Welterweight, Prelims)

Platform comparison

Market context

Polymarket has this welterweight prelim pricing at **0% YES** for Billy Ray Goff, which means the contract is effectively treating Ty Miller as the only live side unless the market reprices before UFC officials post the result. On Polymarket, buyers are funding USDC positions on Polygon through conditional tokens, so the settlement hinge is simple: the official UFC winner, or a 50-50 outcome if the bout is ruled a draw, no contest, cancelled, or pushed beyond the market’s settlement window.

The historical read is one-sided on paper. UFC stats list Miller at **7-0-0** and Goff at **9-4-0**, but the matchup profile is more nuanced: Goff’s UFC metrics show a longer average fight time and a much higher takedown rate, while Miller lands slightly more significant strikes per minute and has the cleaner pre-fight record.[6] Independent stat pages also frame Goff as the more likely stoppage threat, with most of his wins coming by KO/TKO, whereas Miller’s wins lean more towards decisions.[1][2] That sort of style split explains why a near-zero price for Goff does not necessarily mean the outcome is settled; it usually reflects a strong consensus, not certainty.

For traders, the main catalysts are the official UFC bout result, any late card reshuffles, and whether the fight is completed and scored before the settlement deadline. The bout was listed as part of UFC Fight Night: Gamrot vs Salkilld on 8 August 2026, and recent preview material had Miller installed as the market favourite, with Goff priced as the underdog.[4][12][15] If the fight is scratched, ruled no contest, or otherwise not officially decided by UFC, the contract should flip to 50-50 under the market rules.
