Chikadze has lost 4 of his last 5 fights including 3 consecutive losses (one by KO/TKO), showing significant decline. Brito has a better overall record (19-5-1 vs 15-6) and better recent form with wins in his last two outings. Brito appears to be the more in-form fighter, making Chikadze the underdog in this matchup.

Chikadze is a declining 38-year-old on a three-fight skid, coming off a KO loss to Vallejos, and has dropped decisions to grapplers and volume strikers alike. Brito, ~31, is on a two-fight win streak including a first-round submission, with strong wrestling, submissions, and power—a poor stylistic matchup for an aging pure kickboxer with fading durability. Chikadze's one-punch kickboxing power keeps this from being a blowout projection, but Brito's grappling path plus Chikadze's chin/age concerns make Brito a clear favorite. I estimate Chikadze's win chance around one-third.

Chikadze’s recent trend is poor: 1-4 in his last five, including three straight losses and a KO loss most recently. Brito’s record and recent form look stronger overall, with wins in 3 of his last 5 and a dangerous finishing threat. Chikadze’s technical striking and past elite level give him a live chance over 3 rounds, but based on the listed recent results alone, Brito appears likelier to win. I leave meaningful uncertainty because draws/no contests/cancellations are treated as 50-50 and we lack weigh-in or injury information.
