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

Platform comparison

Active sub-markets

Market context

Polymarket has this featherweight prelim priced at **0% YES** for Otari Tanzilovi, which means the contract is effectively saying the market sees no live chance of an official Tanzilovi win at the current screen. Because the market settles on the UFC’s official result and uses USDC on Polygon with conditional tokens, the practical question for holders is not the broader event narrative but whether the bout is fought, scored, and entered cleanly into UFC records before the settlement window closes.

The comparable read here is that the outside sports-betting market has leaned the other way: BetMGM listed Shane Collins as the favourite at **-225**, with Tanzilovi at **+185**, while UFC stats show Collins at **7-0** and Tanzilovi at **10-1**. UFC records pages also indicate their meeting went the distance and was awarded by unanimous decision, which is the kind of outcome that matters for a prediction market because a clean official decision resolves the contract outright, whereas a draw, no contest, cancellation, or late postponement would push it to the market’s fallback handling.

For traders, the immediate catalysts are simple: final UFC bout order, any weigh-in or medical issues, and whether the promotion’s official result matches the scheduled pairing before the deadline. Tapology and sportsbook listings placed the fight on 20 June in Las Vegas, and FanDuel had it starting at 5:00 pm ET, so any change to the card’s timing or status is the main operational risk rather than a change in style match-up. With the contract already at zero for Tanzilovi, attention is on official confirmation rather than price discovery.
