The Number

Chasing the Biggest Edge in Sports

By: Chad Millman

From bestselling author Chad Millman, the story of the hidden force that shapes sports—and now powers America’s gambling obsession

When did everything become a bet? It’s not enough to have an opinion these days—now you’ve got to back it up with cash. Every second of every day, a nation of gamblers is logging on to digital sportsbooks and prediction markets asking one question: What’s The Number? Some call it the line or the odds or the price. But to insiders, it’s The Number. Without it, the action never starts. From NFL games to presidential elections to Oscar races, The Number increasingly shapes the way we experience sports, politics, and life.

In The Number, Chad Millman reveals how gambling became a mainstream obsession, uncovers the secret strategies driving billions of dollars, and introduces the people chasing the ultimate edge. The thirty-year-old Bitcoin maximalist betting tens of millions a year; the NFL prop bettor who won a fortune but nearly lost himself; the investigator who exposed some of sports’ biggest scandals; the ex−Wall Streeter turned prediction market kingpin.

Betting is reshaping sports the way crypto reshaped finance and AI is reshaping technology. The Number explains how it works, why it matters, and where it’s headed next.

Critic reviews

“The Number is an epic piece of literary nonfiction, part The Big Short and part Billions, illuminating the stakes, rewards, and insanity of modern betting, all the lines clear and blurry, and the America that laid the foundation for a multi-billion-dollar revolution. With prose as precise as a prop bet, Chad Millman’s storytelling thrills, terrifies, entertains, and forces you to wonder what’s gained and lost from the games we love.” —Seth Wickersham, ESPN senior writer and New York Times-bestselling author
