Cortes-Acosta vs. Walker odds on Kalshi for UFC Fight Night

Kalshi traders favor Waldo Cortes-Acosta at 68% against 34% for Johnny Walker in Saturday's short-notice heavyweight main event at Meta APEX in Las Vegas. Part of that gap comes from durability. Cortes-Acosta (17-4) is ranked No. 6, has never been finished and weighed in at 262 pounds to Walker's 239.

Cortes-Acosta still has something to prove. He knocked out Ante Delija, Shamil Gaziev and Derrick Lewis in a row, then lost back-to-back unanimous decisions to Alexander Volkov and Curtis Blaydes. He accepted this fight with about a week and a half to prepare and says he wants to win by first-round knockout.

Walker can end the fight with one strike. The 34-year-old Brazilian knocked out Mick Parkin with a first-round knee in his heavyweight debut at UFC 332 and earned a Performance Bonus. He says not having to cut down to light heavyweight has left him feeling stronger.

The concern is timing, because he took this main event on nine days' notice just five weeks after that debut. If Walker connects early, before Cortes-Acosta's size advantage becomes a factor, the 34% price could look cheap.

Other UFC Fight Night odds to trade on Kalshi

Tatiana Suarez’s 65% price against Virna Jandiroba’s 36% sets up a grappling chess match. Suarez has won two straight, submitting Loopy Godinez most recently, while Jandiroba rebounded against Tabatha Ricci. Suarez’s wrestling supports favoritism, but Jandiroba’s submission expertise makes prolonged scrambles dangerous.

Elijah Smith trades at 75% against Davey Grant’s 25%, backed by eight consecutive victories and a 3-0 UFC start. However, Grant has won three of four, giving the 40-year-old underdog more momentum than that price suggests.

Lucas Fernando’s 76% reflects five straight wins, including three consecutive stoppages, but Billy Elekana’s 25% deserves scrutiny, he has won three straight and submitted Junior Tafa last time out. Fernando’s body attacks could prove decisive after his finishing knee against Rafael Tobias.

Nina Milosevic is the strongest favorite at 83% against Priscila Cachoeira’s 18%. Her nine-fight winning streak contrasts with Cachoeira’s three consecutive defeats, while her debut body-shot stoppage demonstrated immediate finishing ability.

Marcos Degli’s 69% against Mitch Raposo’s 32% likewise rewards momentum, Degli brings 13 straight victories and five successive finishes into his UFC debut. Raposo has won consecutive decisions, offering the newcomer an opponent capable of extending matters beyond the explosive opening exchanges and testing his patience.
