The Casino Market is projected to grow from USD 309.54 Billion in 2024 to USD 511.6 Billion by 2032, exhibiting a compound annual growth rate (CAGR) of 6.48% during the forecast period (2024 – 2032). Here are the biggest casinos in the United States.
The United States is home to some of the largest and most varied casinos in the world, including the biggest casino on the planet. While the size of a casino’s gaming floor is often used to measure how large it is, visitors also care about other features. These include the number of slot machines, table games, poker rooms, hotel rooms, and dining options, all of which can be just as important as the gaming area itself.
People often say that size isn’t everything, and this is especially true for casinos. Many visitors come not just to gamble but to enjoy the wide range of activities offered inside. Some may love the excitement of table games or the variety of slot machines, while others may be drawn to the sportsbook to bet on their favourite sports. Many also come for the dining, live entertainment, or family-friendly activities that large casinos in the USA are well known for.
In recent years, some people have chosen to gamble online from the comfort of their homes. However, many still prefer the excitement and atmosphere of visiting a casino in person. These visitors have different interests—some enjoy bingo or poker games like Texas Hold’em, while others come for live shows, fine dining, or relaxing spa treatments.
Most of the large casinos in the USA are more than just places to gamble. They are full-scale resorts offering a wide range of experiences. Many include hotels, concert halls, conference centres, and entertainment for families, such as arcades, escape rooms, and cinemas.

Final thoughts
These ten casinos highlight the scale and diversity of gaming establishments in the United States. From the sprawling gaming floors of Oklahoma to the luxurious resorts of Connecticut and Massachusetts, these venues cater to a wide range of preferences, offering entertainment, dining, and accommodation alongside their gaming facilities.
As casinos keep growing and new gaming laws are introduced in states like New York, this list could change a lot in the coming years. In New York alone, tens of millions of people live within a few hours’ drive, making it a prime spot for large casinos.
Even with the tough competition in Las Vegas, there’s hope that someone might build a massive resort to put the city back on the list of the top ten largest casinos. For example, combining the Wynn and Encore properties in Las Vegas gives about 195,000 square feet of gaming space, but there’s still room to build even bigger.
Although size isn’t everything, these large casinos highlight the wide variety of gambling options in America. From simple slot machine halls to luxurious five-star resorts, they show how much the gambling industry has grown in recent decades.
