When you think you've seen it all in MMA, the sport finds a way to surprise you. Just ask Sean Strickland.

At UFC 328 in Newark, the massive underdog did the unthinkable. In a fight that had the entire MMA world buzzing, Strickland narrowly outpointed the seemingly unstoppable Khamzat Chimaev to capture middleweight gold for the second time in his career. It was a performance that reminded everyone why we love this sport—rankings mean nothing once the cage door closes.

The fallout is seismic. Chimaev, who had looked like a permanent fixture atop the middleweight division, comes crashing out of the Uncrowned men's pound-for-pound top 10 entirely. Meanwhile, Strickland rockets from unranked to No. 9 in our May 2026 rankings. That's what you call making a statement.

But Strickland isn't the only newcomer shaking things up this month. In Saturday's co-main event, 24-year-old phenom Joshua Van delivered a dramatic stoppage victory over Tatsuro Taira that had the crowd on its feet. The young flyweight showed championship mettle in victory, and now all eyes turn to his inevitable rematch with Alexandre Pantoja. Van's arrival in the pound-for-pound conversation signals a changing of the guard in the lighter weight classes.

Our panel of seven expert voters—Ben Fowlkes, Chuck Mindenhall, Shaheen Al-Shatti, Petesy Carroll, Drake Riggs, Eric Jackman, and Conner Burks—carefully ranked both men's and women's pound-for-pound best using a weighted points system. A No. 1 vote earns 10 points, down to one point for a No. 10 vote. The criteria are simple: a fighter must have competed within the last calendar year or have a fight booked. Retirement removes a fighter from consideration entirely.

And while the UFC dominates the conversation, these rankings cast a wider net. From the Bellator/PFL conglomerate to ONE Championship, the best fighters from every major promotion are fair game.

So without further delay, welcome to the Uncrowned MMA pound-for-pound rankings for May 2026—a month that reminded us that in this sport, the only certainty is uncertainty. What a time to be a fight fan.
