Federal Framework
Federal gambling laws do not provide a single definition of illegal gambling but instead establish specific crimes related to operating gambling businesses. The primary federal statutes include the Interstate Wire Act of 1961, which focuses on using communication lines for wagering on sports events, and the Illegal Gambling Enforcement Act of 2006, which targets financial institutions and payment processors. These laws work alongside state laws, which have varying rules about what types of gambling are legal within their borders.
Interstate Wire Act (1961)
This law makes it illegal to use wire communications, including telephone and internet, to place bets or transmit wagering information across state lines, primarily for sports betting. It applies to people engaged in the business of betting and was originally designed for telephone communications but has been interpreted to apply to online communications. Violations can result in fines up to $5,000 and imprisonment for up to two years.
Illegal Gambling Enforcement Act (2006)
The IGEA prohibits unlicensed gambling businesses from knowingly accepting payments from individuals in the United States. It requires financial institutions to prevent payments to illegal gambling operations and targets the financial infrastructure supporting gambling businesses. This law specifically addresses internet gambling and defines illegal gambling as any gambling operation that violates state or federal law.
State vs. Federal Jurisdiction
Most gambling regulation occurs at the state level, where states decide which gambling activities are legal within their borders. Federal law applies when gambling crosses state lines, involves interstate commerce, or uses interstate communications. States may permit casinos, lottery games, poker rooms, and sports betting, while federal law ensures these operations do not extend illegally into other states or use prohibited communication methods.
Who Is Prosecuted
Federal gambling laws primarily target operators and businesses rather than individual gamblers. Prosecutors focus on unlicensed gambling business owners, payment processors, and those facilitating illegal gambling operations. Individual bettors are rarely prosecuted under federal law, though they may face state-level charges depending on their state's specific gambling laws.
