The main card of UFC 318 begins at 10 pm ET. Poirier will be taking on Holloway for the third time in the last fight of his career. He’ll retire in front of a New Orleans crowd, hopefully having Lil’ Wayne wrap the BMF belt around his waist.
Poirier has a 47% chance to win on Kalshi, meaning you can buy a single contract for 47 cents. If he happens to win the fight, you’ll receive a $1 payout. Keep in mind that you can follow along with the bout and trade as the action unfolds. You could find an opportunity to sell your contracts for a profit before the result.
There are also markets for Paulo Costa vs. Roman Kopylov, Kevin Holland vs. Daniel Rodriguez, Dan Ige vs. Patricio Pitbull and Michael Johnson vs. Daniel Zellhuber.
