UFC and Meta launch data-driven rankings system to replace media voting

The UFC launched its new Meta-powered rankings system on Monday, replacing the promotion’s long-standing media-vote model with a data-driven framework built in collaboration with Mark Zuckerberg’s company.

Described as “a new athlete evaluation system transforming how fighters are assessed,” the Meta UFC rankings use statistical modelling and machine learning to evaluate fighters across a range of objective metrics, including outcome probability, win type, fighter trajectory, and weight-class sensitivities. Standings will be updated every Monday following the most recent event.

“I’ve been unhappy with the rankings and always believed there had to be a better way,” UFC president Dana White said in a statement. “We’ve always been a company that runs toward technology and innovation, and now we’ve worked with Meta to integrate it directly into our rankings system.”

Meta founder and CEO Mark Zuckerberg added: “I’m excited to work with Dana and the UFC to build a system that analyses fighter performance at a much deeper level, helping create more transparent and accurate rankings.”

Some of the system’s principles are straightforward: a win over a higher-ranked opponent carries more weight than one over a lower-ranked fighter, inactivity is penalised, and recent bouts have greater influence on a fighter’s placement. The UFC claims the result is a ranking that “accurately reflects their true competitive performance inside the Octagon — nothing else.”

The debut rankings have already drawn scrutiny, however. Alex Pereira enters the heavyweight poll at No. 4 despite having no wins in the division — his only heavyweight appearance ended in a second-round TKO loss to Ciryl Gane at UFC White House on June 14. At flyweight, Kevin Borjas, who holds a 2-4 UFC record, debuts at No. 10 following his upset unanimous decision over Andre Lima at UFC Fight Night 279 last Saturday.

The light heavyweight rankings also raise questions: Jamahal Hill, who has not won since January 2023, sits fifth — one place above Khalil Rountree, who defeated Hill in their most recent meeting last June. At women’s bantamweight, Joseyne Edwards leads the division ahead of former champions Julianna Pena, ranked fourth, and Raquel Pennington, ranked 15th.

Whether the algorithm’s outputs will prove more persuasive than the system they replaced remains to be seen, but the UFC’s embrace of machine learning marks a significant structural shift in how the sport officially measures its competitors.
