The Exciting World of Online Casinos: What You Need to Know

It’s no secret that online gambling has exploded in popularity. What started as a small niche is now a massive industry, raking in billions of dollars annually and showing no signs of slowing down. While sports betting is a big part of this growth, online casinos are also playing a huge role.

The Online Casino Landscape in the US

The United States has seen a bit of a slower start in the online casino world, but things are definitely picking up speed. This expansion is happening just as we saw after a significant court decision in 2018 that opened the door for legal online sports betting. Currently, legal US online casinos are pulling in over $6 billion each year, even though they are only available in a handful of states. This really highlights how much people want them and how much room there is for them to grow. Many are hoping that the situation for online casinos will soon mirror that of sports betting. As of now, online casinos are only fully legal and licensed in eight states. Each state has its own set of rules, but in all these cases, the laws protect licensed casinos from legal trouble and ensure a safe environment for players.

How We Got Here: A Brief History

When online casinos first began appearing in the US, it was a bit of a free-for-all. There wasn’t much need for laws either for or against them. However, as more sites popped up, especially poker sites, concerns started to rise. This led to a nationwide law in 2006, the Unlawful Internet Gaming Enforcement Act, which tried to shut them down. Instead of targeting the operators directly, the law made it difficult for banks and credit card companies to process payments related to online gambling. This had the effect the lawmakers intended. But now, there’s a growing understanding that online casinos can have a place, at least in certain states.

States Leading the Way in Online Casinos

Right now, these eight states have licensed and legal online casinos:

New Jersey

New Jersey has a thriving online casino scene with more than two dozen licensed operators. They clearly have a different approach compared to some other states when it comes to protecting their land-based casinos.

Pennsylvania

Hot on the heels of New Jersey, Pennsylvania also boasts around 20 online casinos.

Michigan

With a substantial number of licensed operators, Michigan has established the third-largest online casino market in the country.

Delaware

Delaware has three online casinos, operated by Delaware Park, Dover Downs, and Harrington Raceway & Casino. These are all powered by Rush Street, under the guidance of the Delaware Lottery.

Connecticut

Residents and visitors have been able to play online since a landmark law passed in 2001. The main online casinos here are run by DraftKings and FanDuel.

West Virginia

With about 10 online casinos, West Virginia has attracted major players like Caesars, BetMGM, and DraftKings.

Rhode Island

After legalizing online gambling in 2023, Rhode Island launched its first online casino in March 2024. Play is restricted to residents aged 21 and over.

Nevada

You might think the home of America’s gambling capital would fully embrace online casinos, but that’s not quite the case. Perhaps to protect the iconic land-based establishments, only online poker is currently permitted.

The Next US States Gearing Up for Online Casinos

There are two more states that have officially approved online casinos but haven’t licensed any operators just yet. Maine passed the necessary legislation in January and is expected to have casinos up and running by the end of 2026. Similarly, Wisconsin legalized them in April 2026 and is anticipated to follow a similar timeline.

What’s Next for US Igaming?

It’s highly likely that many more states will decide to legalize online casinos in the coming years. This is due to a more open attitude towards the activity and the potential for states to generate much-needed tax revenue and licensing fees. Even the major casino and entertainment companies are recognizing the trend. If they can’t compete with online operators, they’re joining them. Expect to see them actively lobbying state legislatures soon, which is great news for anyone hoping to play at online casinos in their home state.
