27 fighters are eligible. Here are our top 12, with the UFC's official and Meta rankings beside them. These are FightIQ's own data rankings, not the UFC's: see the UFC's official Women's Flyweight rankings.
We fit one strength rating per fighter from every UFC fight, and older fights count for less (a fight loses half its weight every three years). We rank on the cautious end of that rating, strength minus one unit of uncertainty, so a short record has to show more before it climbs. To appear in the top 15 a fighter needs a win over a ranked opponent, and to sit in the top five a win over a then-top-10 opponent. Read the full method.
Our data: #1 · 9-0 in the UFC, 7-0 since 2023; 9 UFC fights at Women's Flyweight; best wins Alexa Grasso (then-#1 at Women's Flyweight, 2025) and Rose Namajunas (then-#6 at Women's Flyweight, 2026); 9-fight win streak
How to read it. The bar under each name is the plausible strength range; the white tick is our best estimate, and we rank on the left end. A wide bar means thin evidence. provisional entries are ranked where the numbers put them, and the label says the evidence is thin. The arrows show how many places we rank him above (▲) or below (▼) each list; gold means a gap of 3 places or more against the UFC's official rank.
