In most states in the United States, it is illegal to bet on college football, either through a bookmaker or through an online sportsbook. However, there are some exceptions to this rule.

Additionally, some states have legalized sports betting but have not specifically addressed the issue of betting on college football. In these states, it is unclear whether betting on college football is legal or not.
In general, it is advisable to check the laws in your jurisdiction before placing any bets on college football. If you are unsure about the legality of betting on college football in your area, it is best to err on the side of caution and avoid doing so.
