The Interstate Wire Act of 1961, often called the Federal Wire Act, is a United States federal law prohibiting the operation of certain types of betting businesses in the United States. It begins with the text:
In 2011, the Department of Justice released to the public a formal legal opinion[2] on the scope of the Act concluding that "interstate transmissions of wire communications that do not relate to a 'sporting event or contest' fall outside the reach of the Wire Act."
The U.S. Fifth Circuit Court of Appeals has ruled that the Wire Act prohibition on the transmission of wagers applies only to sports betting and not other types of online gambling.[3] The Supreme Court has not ruled on the meaning of the Federal Wire Act as it pertains to online gambling.
