NBA Sports Betting Using Machine Learning 🏀

A machine learning AI used to predict the winners and under/overs of NBA games. Takes all team data from the 2007-08 season to current season, matched with odds of those games, using a neural network to predict winning bets for today's games. Achieves ~75% accuracy on money lines and ~58% on under/overs. Outputs expected value for teams money lines to provide better insight. The fraction of your bankroll to bet based on the Kelly Criterion is also outputted. Note that a popular, less risky approach is to bet 50% of the stake recommended by the Kelly Criterion.

Packages Used

Use Python 3.8. In particular the packages/libraries used are...

• Tensorflow - Machine learning library
• XGBoost - Gradient boosting framework
• Numpy - Package for scientific computing in Python
• Pandas - Data manipulation and analysis
• Colorama - Color text output
• Tqdm - Progress bars
• Requests - Http library
• Scikit_learn - Machine learning library

Usage

Make sure all packages above are installed.

$ git clone https://github.com/kyleskom/NBA-Machine-Learning-Sports-Betting.git
$ cd NBA-Machine-Learning-Sports-Betting
$ pip3 install -r requirements.txt
$ python3 main.py -xgb -odds=fanduel

Odds data will be automatically fetched from sbrodds if the -odds option is provided with a sportsbook. Options include: fanduel, draftkings, betmgm, pointsbet, caesars, wynn, bet_rivers_ny

If -odds is not given, enter the under/over and odds for today's games manually after starting the script.

Optionally, you can add '-kc' as a command line argument to see the recommended fraction of your bankroll to wager based on the model's edge

Flask Web App

This repo also includes a small Flask application to help view the data from this tool in the browser. To run it:

cd Flask
flask --debug run
