As there is no federal law against playing online, simply placing wagers online is legal. (However, a wager must NOT be placed on a site located in the United States. More on that later.) There is a small chance players might run afoul of state law, but there is little chance of prosecution. The only case cited where a person got into trouble with a state was in 2003. Jeffrey Trauman of North Dakota paid a $500 fine on over $100,000 of online sports bet winnings.
Sites that are set up outside of the United States are legal. Therefore, gambling on websites located in areas like Australia, the Caribbean, and Latin America is legal. Just be very clear that the site you are playing on is not based on U.S. soil.
Definitely Not Legal
It is never legal to gamble on a website based in the United States. Also, if you are planning to operate an online gambling site, stay outside of the United States. You must also deal only with casino and poker wagers (not sports bets) from people in the US. And you cannot take bets over the phone from people in the United States.
Accepting online gambling advertising is also illegal. If you are a small publisher, you are less likely to be prosecuted, but why risk it? As of early 2009, only large and mid-size publishers had faced prosecution. In 2007, the three big search engines (Google, Yahoo, and Microsoft) each paid a fine for accepting online gambling ads, but did not face criminal charges. Other publishers, such as Esquire Magazine, have been warned by the government not to take online gambling advertising.
Facilitating the transfer of funds to online casinos is also a bad idea. As of 2006, it became illegal for American banks to process transactions originating from or directed toward any online gambling operator. Because of this, several sites then refused to take bets from American players. But as the law seems difficult to enforce, it has not turned the tide completely for American players.
Still Up In the Air
Advertisers who promote sports books in magazines and on billboards may or may not face prosecution. So far, sports books have never been scrutinized for advertising online. And online casinos, poker rooms, and sports books have never been prosecuted for buying ads.
So what is the bottom line?
Online casinos and operators still accept American players. And international financial parties have continued to process their transactions. The legality is always changing and there have been attempts to declare online wagering against the law, but for now, US citizens who simply place bets online are in the clear.
