AI 78% · crowd 60% on Tuchalov (+18)

18-point gap. Same winner, but the AI backs Tuchalov noticeably harder than the crowd does.

The breakdown

Tuchalov is an undefeated prospect with explosive finishing power (80% finish rate, 4 KOs in 5 wins) and recent momentum, including a dominant R1 KO over Caio Machado—a fighter Ribeiro beat by split decision just months earlier. Ribeiro, meanwhile, is in freefall: three consecutive losses, all by finish (two TKOs, one submission), suggesting deteriorating cardio, defense, and composure under pressure. At 29, Ribeiro may be entering decline; Tuchalov at 26 with Dagestan pedigree is ascending. Ribeiro's striking output (3.04/min) and takedown rate (0.85/15min) are modest, and his 43% striking accuracy and TD accuracy won't suffice against a heavy-handed finisher who has shown no defensive vulnerabilities in five fights. Tuchalov's size (6'5") and reach advantage are real; Ribeiro's 81-inch reach won't close the gap cleanly.

Ribeiro — edges

  • Experience: 17 UFC/pro fights vs Tuchalov's 5
  • Submission threat: 7 submission wins, 0.57 sub attempts/15min
  • Familiarity with ranked/veteran opposition

Tuchalov — edges

  • Perfect record (5-0) with 80% finish rate and recent momentum
  • Height and reach advantage (6'5" vs 75in)
  • Explosive striking power: 4 KOs in last 5 fights
  • Age and physical prime (26 vs 29)

X-factor

Ribeiro's submission defense and grappling acumen could extend fight past R1, but form suggests he won't survive early onslaught.

About these numbers

Market probability is the live crowd consensus from Polymarket, a public prediction market where people trade on outcomes — we read it as a data signal for what the crowd expects, and it updates continuously. AI probabilityis our own model’s independent read of the matchup from fighter data alone; it never sees the market price, which is why the two can disagree.

All of it is published for analysis and entertainment. Nothing here is betting advice, a recommendation, or a prediction of a guaranteed result — fights are volatile and upsets are the sport.
