Calibrated UFC fight predictions — every engine measured against the closing line, every miss shown next to every hit. No accuracy theatre. Just whether a stated 70% actually happens 70% of the time.
Every card graded before the walkouts, settled the morning after. The next one drops here the moment it's announced.
UFC betting markets are close to efficient — the closing line wins about two-thirds of the time. So we measure calibration, not bravado, and beating the market is the only result that would mean anything.
Name two fighters and the reader returns a calibrated lean, a confidence band, and the one stylistic factor that tips it — in UNFOLD's honest voice. Qualitative only: no invented records, no odds, no bets.
Each point is a confidence bucket. The dashed diagonal is perfect calibration — above the line means we were too cautious, below means too sure of ourselves. The market sits almost exactly on it. That is the standard our engines are measured against.
Distance from the diagonal is the error. An engine can pick winners often and still be badly calibrated — which is why accuracy alone is a poor way to choose between models.

MARKET is the de-vigged closing line, not a model of ours — beating it, not beating a coin flip, is the only result that would mean anything. BOOKWORM has fewer than 25 scored picks, so its Brier is not yet meaningful. Accuracy figures exclude 260 picks from two 2026 events reconstructed after the fact; they remain in the record but are not counted as predictions. Analysis and entertainment only.
