Named one of the most anticipated nonfiction books of 2026 by The New York Times Book Review

The definitive, colorful history of American sports betting that challenges the dialogue around one of our country's fastest growing (and most controversial) industries.

Taking listeners on a rollicking journey through the history of American sports betting, Over/Under proposes a fascinating and unexpected theory: What if sports betting isn't just a result of the multibillion-dollar American sports industry, but rather the primary reason for it? An essential catalyst for nearly two hundred years of sports fandom and obsession?

The narrative starts in mid-nineteenth-century New York City, as a new sport called baseball lures bettors out of shadowy gambling halls and into the fresh air. The story then heads to Churchill Downs and Augusta National Golf Club where sports betting dresses up in fancy outfits, to Chicago and Minneapolis where sports betting meets the Mafia and gets some structure, and to Las Vegas and the Caribbean where sports betting makes some people very rich.

Along the way, the story rolls out a cast of colorful characters: hustlers, wise guys, moguls, opportunists, grifters, touts. A parade of personalities, year after year, all trying to make a quick buck. Because isn't that the whole point?

Written for those eager to explore the history of a recently-legalized industry—one that's been described both as a financial bonanza and an impending disaster—Over/Under is poised to become the definitive history of a controversial industry in the midst of incredible, yet uncertain, growth.
