A bespoke equine biomech model for buyers who measure before they bid.
One standard behind every number: mature horses with complete race records, top-rated vs bottom-rated at the same price. No buy-cheap effect, no survivorship trick.
Top-rated yearlings returned 30% more prize money per dollar than bottom-rated — at the same price. On our most complete cohort yet, holding across both sexes and every complete vintage. Price- and survivorship-controlled.
Choosing between two foals of the same sire? Across 142 sires, our top-rated progeny returned 31% more per dollar — pedigree and price held constant. The one number that beats both "you just bought cheap" and "you just bought the right sire."
19.4% vs 14.5%. Top-rated yearlings are a third more likely to still be racing deep into their careers — when the real money is paid. Soundness is the edge.
The value edge holds on both sides of the catalogue — +38% for fillies, +22% for colts. Not a fluke of one population.
The prize-money-per-dollar edge is positive across every yearling vintage with mature careers (2020–22). A repeatable signal, not a single-year fluke.
The signal is rare on purpose. Net +8 = top 1.5% / 1 in 66. Few horses clear it — and that's the point.
The claims aren't modelled — they're measured against 6,127 mature Australian racehorses with complete career records. Real prices in, real prize money out.
Every yearling we've put through the model — Inglis, Magic Millions and NZB, 2019 to 2026. The data asset behind every score.
Every horse in the cohort, plotted on two of the biomech metrics that drive the score.
“Above $300k the model loses traction — the market is too inefficient at the prestige end. Below that ceiling — where 7 out of 10 bids land — our top-rated yearlings return 30% more prize money per dollar at the same price.”
