We record fight cards from the official posters each stadium publishes on its own social media, starting 1 January 2026.
A fight on MuayThaiTime means the fighter was on one of those official cards.
Cards often change on the night (late withdrawals, substitutes, cancellations), so a listed fight may not have happened exactly as printed. Stadiums also run undercard bouts that aren't on the official poster; we don't track those.
Rankings count these card appearances, not wins or losses. We're building results tracking to confirm who actually fought.
