Market context

Priscila Cachoeira faces Chelsea Chandler in a women's bantamweight preliminary bout at UFC Fight Night: Muhammad vs. Bonfim on 6 June 2026. The market currently prices Cachoeira's victory at zero, reflecting either minimal trading activity or strong conviction toward Chandler among early participants. On Polymarket, this conditional token trades against USDC on Polygon, settling to either fighter's name or 50-50 if the bout ends in a draw, technical draw, no contest, or cancellation beyond 20 June.

Cachoeira, a Brazilian fighter with a mixed record across multiple promotions, has competed sporadically in recent years, whilst Chandler's recent form and activity level remain relevant benchmarks for assessing the 0% pricing. Historical UFC preliminary bouts involving less-established bantamweights often see thin liquidity and wide probability spreads, particularly when one fighter carries stronger recent momentum or recognisable recent wins. The current zero probability suggests traders either lack conviction in Cachoeira's chances or have not yet engaged with this contract meaningfully.

Traders should monitor UFC official announcements regarding fighter withdrawals, weight-cut complications, or schedule changes through early June. Recent injury reports or last-minute replacement fighters could shift the conditional token's value substantially. The settlement window closes at 03:59:59 UTC on 7 June, giving a narrow window for post-fight resolution. Any technical issues—judges' scorecards delayed, medical stoppages, or controversial decisions—could trigger the 50-50 resolution clause, which currently carries no explicit probability on-chain.

Methodology

We track UFC Fight Night: Priscila Cachoeira vs. Chelsea Chandler (Women's Bantamweight, Prelims) on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
