How It Works
In Greek myth the Moirai are the three Fates — the goddesses who spin, measure and cut the thread of every mortal life. This site points their job description at a fight card: read the thread of a bout before it's fought, and say where it leads. Free, no signup.

Spin the matchupCLOTHOEvery fighter's whole career — striking, grappling, skill ratings, age and reach, durability, style clashes — is pulled from decades of UFC history and woven into one matchup.

Measure the win chanceLACHESISAn ensemble of gradient-boosted models turns the matchup into a win probability, then calibrates it — a stated 65% wins about 65 times in 100 — and labels it High, Medium or Low confidence, by how closely its models agree and how much UFC history both fighters have.

Mark the valueWherever a sportsbook has posted a price, Moirai flags the bets where its own read beats the book, and lays out one disciplined, risk-capped slate per card instead of a pile of long shots.
Honest about the edge
A market only earns a value flag after it has shown an edge in testing. Moneyline: the model's numbers beat the early line on average, though not the closing line, so moneyline value is flagged early in fight week. Props: only method, inside-the-distance and winning-round bets have earned a flag. Everything else is shown for context and never flagged. The Results page grades every locked pick and the running P&L, wins and losses alike.
What Moirai is not
Not an oracle, and not betting advice. It's free, takes no affiliate money from any sportsbook, and shows what each market actually returned in testing so you can judge it yourself. The Fates were never wrong; a model always can be. Gamble responsibly, only with money you can afford to lose — 21+ in most places, 18+ in some.
