UFC Fight Night: Otari Tanzilovi vs. Shane Collins (Featherweight, Prelims)

Platform comparison

Active sub-markets

Market context

Otari Tanzilovi’s featherweight prelim against Shane Collins is a live UFC bout rather than a settled mismatch, which matters because the market is currently pricing a complete absence of YES support at 0%. Pre-fight odds have still leaned towards Collins: BetMGM listed him at -225 with Tanzilovi at +185, while FanDuel markets also positioned Collins as the shorter-priced side, suggesting the crowd is following the same basic read of undefeated form and UFC debut dynamics.[1][8] UFC stats list Collins at 7-0 and Tanzilovi at 10-1, with both fighters at 145 lbs, so this is being treated as a closely matched entry into the promotion rather than a title-level test.[5]

For a market with this kind of thin opening interest, funding friction can matter as much as fight analysis. On Polymarket-Klarna-style rails, deposit speed, card acceptance, and withdrawal options such as Klarna, SEPA and USDC affect how quickly new money arrives ahead of the bout, and that in turn can change book depth even when the underlying event is unchanged. The practical catalysts are simple: any official UFC bout-sheet update, late weigh-in issue, or card reshuffle would be the main reason this market re-prices, while the scheduled outcome still resolves only from the UFC’s official result.[2][3] Because the contract is tied to an event scheduled for 20 June 2026, the key watchpoint is whether the fight starts and finishes on the night; if it is delayed, cancelled, or ruled a no contest, the settlement path moves away from a straight fighter-vs-fighter binary.[2]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
