UFC Fight Night: Melissa Mullins vs. Bia Mesquita (Women's Bantamweight, Prelims)

Market context

Melissa Mullins is due to face Bia Mesquita in a women’s bantamweight bout on the UFC Fight Night prelims, and the market’s 0% YES tag implies traders are treating Mullins as a very unlikely winner. That is consistent with wider pre-fight pricing: DraftKings had Mesquita as a heavy -600 favourite, with Mullins at +440, while UFC coverage framed Mesquita’s recent grappling run as the key edge.[1][8]

For prediction markets, this kind of low starting price usually reflects a combination of perceived skill mismatch and thin early liquidity, which is often amplified when deposits are slightly cumbersome. Markets tied to fast-growing UFC cards tend to deepen when on-ramp flows are easy, especially where users can move funds in via lower-friction rails such as SEPA or card-based methods, or fund quickly with USDC rather than waiting on bank transfers. In practical terms, that means the book can stay shallow until more traders have cleared their deposits and the fight draws nearer.

The main catalysts are straightforward: the bout needs to start and finish as scheduled, and the official UFC result must be posted cleanly for the market to settle. Tapology lists the fight for UFC Fight Night: Kape vs. Horiguchi on 20 June 2026 at the UFC Apex, and UFC.com had already described Mesquita as quickly rebooked into this matchup.[3][8] If the card order changes, the fight is delayed, or late injury news forces a cancellation, the market can move away from a simple two-way outcome and towards the contract’s 50-50 or resettlement logic.
