What is the Kelly Criterion?
The Kelly Criterion is a math-based way to find the best bet size. It looks at the odds of winning and losing. The kelly criterion formula is:
f* = (bp – q) / b
In this formula, b is the net odds, p is the win probability, and q is the loss probability. It helps you decide how much of your bankroll to risk on a bet.
Historical Background of the Formula
The Kelly Criterion started in gambling to help bettors win more. Introduced by John L. Kelly Jr. in 1956, it has grown beyond gambling. It’s now used by investors and financiers to manage their assets wisely. Knowing its history shows its value in both gambling and finance.

Maximizing Your Bankroll Growth

How the Kelly Criterion Works
The Kelly Criterion offers a clear method for betting in sports. It’s key to understand true odds and implied probability. This helps decide how much to bet based on your odds against the market’s.
Explanation of the Kelly Formula
The Kelly Criterion uses a simple formula: f* = (bp – q) / b. Here, f* is the bet fraction, b are the odds, p is the win chance, and q is the loss chance. This formula helps maximize your returns.
True Odds vs. Implied Probability
True odds show the real event chance, based on history and stats. Implied probability is what odds suggest an event’s chance. Knowing the difference is key. A better true odds chance than implied means a good bet.
The Calculation Process
First, find the true odds of an event. Then, compare them to the bookmaker’s implied probability. If your odds are higher, it’s a good bet. Using the Kelly Criterion can lead to long-term betting success.
