The Math That Turns a Huge Liability Into a Diversified Portfolio

At this year’s British Open, Rufus Peabody bet roughly $35 million against golfers to win. In 2024, he risked about $2 million to win $35,000 on eight players not winning. The founder of Massey-Peabody Analytics explains how he runs a betting book like an options portfolio. He sizes every position with the Kelly criterion, hedges only when the other side shows value, and grades his models on “expected win” instead of raw results. He also explains why prediction markets could become the source of truth for prices, why bettors underprice whoever is leading a golf tournament, and why adding complexity to his models has sometimes made them worse.
