The Indianapolis 500, or more simply the Indy 500, is always one of the top sports betting events of the summer in the United States. The event takes place every Memorial Day weekend at the Indianapolis Motor Speedway in Speedway, Indiana, and this year is no different. 

A stacked 33-car field powered by some of the top IndyCar drivers in the world should be a whole lot of fun to watch – and to make it even more exciting, you can bet on the race at all the best sports betting sites and grab some great deals at the same time.
