What this means for a fight

Stance barely matters, and that is the finding. The less common stance has a small, steady advantage and no more. Most fighters spend their training life facing orthodox opponents, so the southpaw is the look they have seen least.

Correlation is not causation. The gap is small, and fighters who fight southpaw or switch are not a random sample of fighters.

How we counted

Every UFC bout on the official statistical record from 11 March 1994 to 10 October 2026 that had a winner. Draws, no-contests and overturned results are left out of every count. Stance is the fighter's current stance on the official UFC register, applied to every bout, so a fighter who changed stance mid-career is counted with the stance they are listed with now. Bouts between two fighters of the same stance are left out.

Anything built from a fighter's history (debuts, runs, breaks, previous meetings) only looks at UFC bouts dated before the fight, and leaves out the few names the register holds for two different fighters. A row needs at least 30 fights to be drawn or quoted; smaller rows are listed as too few to call. The 95% range is a Wilson interval: where the true rate probably sits, given how many fights there are.
