The United States court condemned all online sports betting, making them all illegitimate under the Wire Act, except for horseracing bets. All forms of online transactions were completely illegalized but in 2006, the US federal government had to pass the Unlawful Internet Gambling Enforcement Act of 2006, as transactions from bank institutions are very similar to online gambling transactions.
It was not until November of 2010 when the state of New Jersey passed the bill S490 to make a specific number of online gambling varieties legal. This bill has allowed citizens of New Jersey to make bets on poker, slots and other casino games but excluded sports betting. This bill was the beginning of a new era for the USA gamblers as other states followed New Jersey's legalizing course of action.
Poker, slots and other casino games are now legal in the states of Delaware, New Jersey and Nevada. Delaware became the first state to legalize online gambling on June 2012; New Jersey became the third state to legalize online gambling while Nevada became the first state to legalize poker. Other states like Oklahoma have not particularly banned online gambling but they have prohibited all kinds of gambling.
In May 2018, the Supreme court ruled against the validity of the Professional and Amateur Sports Protection Act of 1992 (aka PASPA). Now, each state has the ability to allow legalized sports betting for its residents.
With the right to decide the sports betting issue remanded to the state level, a number of states, including New Jersey, Mississippi, Delaware, Pennsylvania, Rhode Island, Iowa, New York, Indiana, Oregon, New Mexico and West Virginia, joined Nevada as the only states where sports gamblers could legally bet on sports events.
