At events outside the US, the local fighter won 62% of unanimous decisions (390 bouts) and 57% of split or majority decisions (109), and 58% of fights that ended in a finish (533). At US events the same three figures are 49%, 50% and 44%.

The local fighter’s win rate, split by how the fight ended, at home and abroad.

Correlation is not causation. These rates describe results; they do not show why a decision went one way. Home fighters at events abroad are not a random sample of fighters either.

Descriptive only. This page describes past UFC results; it is not a forecast.

The visiting fighters at events abroad are a selected group, as the home-country page explains. The same applies here.

What counts. Bouts with exactly one local fighter, split by how the fight ended: a finish, a unanimous decision, a split or majority decision, or any other result. The figure is how often the local fighter won. Result types. A finish is a KO or TKO, a submission, a doctor stoppage or a fighter unable to continue. “Disqualification or other” covers disqualifications, overturned results and any other ending; those rows are tiny and unreliable. Small samples. Rows with fewer than 30 bouts are greyed and marked small sample. They are shown, not dropped.
