Top March Madness Betting Sites for 2023

Every college basketball fan waits all year for NCAA March Madness to begin and it starts with the conference tournaments in March followed by the Big Dance and ends with the final two teams vying for the national championship in April.

A college basketball betting site will take in more bets during March Madness than any other time of the year. Although the Super Bowl is the single most widely wagered sporting event in the United States, no tournament sees more betting action on its individual games than the college basketball tournament.

You will find that the best online sports betting sites have the widest variety of betting markets and a list of every team in the tournament with accompanying odds to win the national title.

There is no prohibition against betting on March Madness in the United States and with the advent of legal sports betting in over 33 states, and with more to come, many people now understand that offshore online sportsbooks offering even better odds on the 64 college teams in the NCAA Division 1 college basketball national championship.

Offshore sportsbooks are not regulated by the U.S. market and therefore can offer better lines, odds, and bonuses than domestic sportsbooks. This is a noticeable advantage that the offshore sites enjoy and one that is passed on to the customers doing business with them.
