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.
The latest fights in the headline row
The most recent UFC fights counted in the headline row (southpaw vs orthodox).
Every UFC bout on the official statistical record from 11 March 1994
to 17 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.
