8th Day Verdict

The 8th Day Engine makes Ilia Topuria the pick at 64% with medium confidence — the age curve drives most of the edge. The case: at 29 to 37, the age curve tilts toward Topuria. Pushing back: Gaethje brings the stronger recent run (WWWLW); a height advantage for Gaethje. The betting market reads it 21% / 79%, and that consensus carries half of the final number. Worth knowing: the raw model sees this fight markedly closer than the betting line — the market's conviction in Topuria is doing much of the work here. If Topuria gets it done, the scorecards is the most likely route (60%).

⚠️
How to read this page: the win-probability split on each bout is the 8th Day Engine — a deterministic model blending fighter records, finishing profiles, form, age, layoff, reach and stance with the live betting market. Market figures are the de-vigged bookmaker consensus. Confidence: High needs a 15-point edge on near-complete data; Medium a 7-point edge; tighter — or built on thin data — is Low.
