The Billion-Dollar Racing Algorithm
Blacklisted by US casinos, physicist Bill Benter landed in Hong Kong with Thorp's toolkit and cracked horse racing — 17 years, hundreds of thousands of bets, ~$1B.
— Robert B.
In 1984, blacklisted by 80% of American casinos, physics-grad Bill Benter landed in Hong Kong carrying the same toolkit Thorp used in 1961 — computer + probability model + Kelly formula — to crack the deepest, most complex racing market in the world. For the first three years he lost everything.
After restarting, with a 100+ variable model and Kelly's disciplined sizing, he bet hundreds of thousands of times over 17 years for a cumulative profit of about US$1 billion — Guinness-certified as the highest single-betting-game earnings in history. His information edge over consensus was just 2-5 percentage points.
"It was those 2-5 percentage points of edge — through hundreds of thousands of repetitions and Kelly's disciplined amplification — that compounded into a billion dollars."
A tiny edge × many repetitions × Kelly sizing = the direction of compounding. That is exactly the logic of F-Star spreading capital by Kelly across strategy pools and settling day after day.
