What Is a Longshot in Betting?
Odds, payouts, implied probability, and how to read a longshot line in any sport — the complete beginner's explainer.
Read the guide →A longshot is the most misunderstood bet in sports. We break down what it really is, the math behind it, and how to find the few underdogs actually worth your money.
In betting, a longshot is a wager the sportsbook prices as unlikely to win — which means it pays a lot if it does. The term comes from horse racing, where a horse given long odds was called a "long shot." The idea carried over to every sport.
A longshot might win 1 time in 5 (or far less), but when it hits, it pays back several times your stake. That's the trade: lower hit rate, bigger reward.
Longshots show up as big American numbers (+400, +900, +2500), decimals of 5.00 or higher, or fractions like 9/1. The bigger the number, the longer the shot.
Sportsbooks build a margin into every price — and that margin grows larger on longshots. The house's edge is biggest exactly where the dream of a big payday lives.
A longshot is only a good bet when the odds pay more than the real chance of winning. Finding that gap — called positive expected value — is what separates smart longshot bettors from gamblers.
Evergreen, no-hype reads that cover the definition, the strategy, and the process — so you can think clearly before you place a longshot bet.
