Valter Walker has his brother’s calendar filled out for 2027, and it ends with UFC heavyweight gold.
The ranked heavyweight took to X after Johnny Walker knocked out Waldo Cortes-Acosta in the third round of the UFC Vegas 124 main event, and he skipped right past cautious optimism. “I say it and I’ll say it again. My brother is going to be champion next year and will defend the title against anyone,” Valter wrote. The post was in Portuguese, and that’s the English version Yahoo Sports and Sherdog ran.
He also took a victory lap on the weight-class move. Valter said he’d been pushing Johnny to go up to heavyweight for a long time, and he made sure everyone remembered it. “My brother, the guy who made me a fighter, is f*cking awesome!!! (I told you he needed to move up to heavyweight a long time ago),” he wrote.

The post came with receipts of a different kind. Valter shared a screenshot of a bet his wife’s cousin placed on Johnny, a $5,000 ticket that cashed for $13,750. Good week for that side of the family.
How Johnny got here
The win itself was a short-notice job. Johnny took the Cortes-Acosta fight on Saturday at the Meta Apex in Las Vegas without a full camp for it, and the early rounds weren’t comfortable. He took heavy pressure, stayed upright, and then put Cortes-Acosta away in Round 3.
That’s two knockouts in two heavyweight fights. Johnny (24-10, 1 NC) left light heavyweight after a rough stretch in the division where he used to be a contender, then debuted at heavyweight in October by knocking out Mick Parkin in the first round. A month later he’s headlining against Cortes-Acosta and leaving with another finish.
Valter, the younger Walker, sits at 16-1 and holds a ranking of his own in the division. That raises the obvious problem of two brothers climbing the same ladder, and Johnny shut it down after the Cortes-Acosta fight. He said he will never fight Valter. So if both of them keep winning, the UFC’s matchmakers are going to have to route around a family dinner.
No next opponent was attached to any of this. Valter’s prediction is the only timeline on the table right now.
Quick take
I love a guy who says yes to a short-notice main event, eats a rough first two rounds, and still finds the knockout. That’s the Johnny Walker who made people pay attention at 205, minus the stretch where it stopped working. Heavyweight forgives a lot. It rewards guys who hit hard and can take one, and so far Johnny has done both. Two first-year knockouts doesn’t make a champion, and Valter is a brother before he’s an analyst. But the blood relative who called the weight move years ago now has a $13,750 betting slip and a 2-0 heavyweight run backing him up. I’d want to see Johnny against a ranked name with a full camp before I sign off on 2027, and that fight is the one the UFC should book next.
