UFC Fight Night: Manoel Sousa vs. Richie Miranda (Lightweight, Prelims)

Platform comparison

Market context

Manoel Sousa fought Richie Miranda in a three-round lightweight prelim at UFC Fight Night in Las Vegas, and the official result was Sousa by unanimous decision, 29-28 across all three scorecards.[1] For a programmatic trader, that means the market should now be treated as an event-complete node rather than an open price discovery market: any bot, scraper, or copy-trading rule should verify the UFC’s official result feed before settling exposure, because the market’s resolution source is the UFC itself.[1]

The pre-fight framing was a classic near-equal-prospect matchup with a strong favourite layered over an undefeated-looking challenger profile: Sousa entered at 14-1, while Miranda came in at 13-1 and was making his UFC debut after a run as LFA lightweight champion.[9][11] Comparable spots on the slate generally resolve away from the crowd’s initial extremes only when there is a late cancellation, a no contest, or a judging upset; here, the actual result aligned with the market’s heavy YES bias and did not require any special-case settlement logic.[1][16]

For traders automating conditional orders, the key catalysts were always bout status changes rather than in-play volatility: official bout announcements, weigh-in completion, and any last-minute medical or commission withdrawals. Public listings had the fight scheduled for UFC Fight Night: Gamrot vs Salkilld at the Meta APEX, with multiple pre-event pages marking it as a live prelim and no reported injuries or roster changes before the card.[2][6][11] Because the market also pays out 50-50 if the bout is cancelled, postponed beyond 22 August 2026, or ends as a draw or no contest, a bot should watch for UFC card updates and commission result notices right up to settlement cut-off.[11][16]

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
