About Betting App Index
Betting App Index publishes guides on what a bet costs on different apps and how sportsbooks differ from prediction markets. The Betting App Index editorial team writes and reviews the guides.
What the guides cover
App comparisons: fees, vig, limits and withdrawal times on sportsbooks and prediction markets.
Pricing: implied probability, de-vigging, closing line value and the math behind arbitrage.
State guides: where sports betting is legal, the minimum age and which apps operate there.
Popular bets: the bet types people use most in each sport, from the NFL and NBA to Formula 1.
How guides are researched
Guides start from primary sources wherever they exist: fee schedules, exchange rulebooks, regulatory filings and state laws. Almost every guide ends with a list of the sources it used, and many note the date those sources were last checked. Each post shows the date it was published.
Updates and corrections
Fees, rules and state laws change often. When one changes, the guide that covers it is updated and its sources are checked again.
The guides explain how pricing works. They don’t recommend specific bets, and they aren’t financial or legal advice. Check current prices and rules in the app before you bet.
Responsible betting
Sports betting involves risk. Only bet what you can afford to lose, and follow the laws where you are. If gambling has become a problem, call 1-800-MY-RESET.
