Market context

Priscila Cachoeira, the Brazilian bantamweight with a record spanning multiple promotions, faces Chelsea Chandler in a preliminary bout at UFC Fight Night: Muhammad vs. Bonfim on 6 June 2026. The conditional token for Cachoeira victory currently trades at zero on Polygon, reflecting either extreme confidence in Chandler or minimal liquidity in this prelim-level matchup. On Polymarket, this zero price means traders are pricing in either overwhelming likelihood of a Chandler win or genuine uncertainty about whether sufficient volume will accumulate before settlement.

Cachoeira's recent history shows inconsistency at bantamweight, with losses to ranked opponents interspersed with victories over lower-ranked competition. Chandler, conversely, has built momentum through the regional circuit and enters with recent wins. The 0% YES probability mirrors typical Polymarket behaviour for preliminary fights where fighter recognition remains low; comparable prelim contracts often see minimal trading activity until fight week, when sharper action typically emerges. Historical precedent suggests these zero-priced prelim contracts occasionally spike sharply once mainstream betting interest activates.

Traders should monitor UFC official announcements regarding fighter withdrawals or weight-cut complications, which could trigger a 50-50 resolution. Fight week media coverage and any late injury reports will likely drive the first meaningful price movement. The settlement window closes 7 June at 03:59:59 UTC, allowing roughly 24 hours post-fight for official UFC confirmation. Given the preliminary status and current illiquidity, significant slippage should be expected if meaningful volume enters the market.

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.
