Top 5 Most Expensive Casinos In The World 2021

If you thought casinos were just for gambling, think again—Casinos around the world offer opulent spaces to gamble & play, high-end experiences for patrons and a host of other luxurious offers to attract visitors. But what are the most expensive casinos ever? We're ranking the top 5 most expensive casinos in the World based on cost to build, sheer size, and other extravagant extras.


What are the most expensive and luxurious casino in the world? If you’ve ever made a trip to Vegas or Macau (which—spoiler alert, doesn’t feature on this list), you’ll know that brick-and-mortar casinos are constantly competing for customers with luxury, extravagant comfort and opulent surroundings.

In the 21st century, offering a high-end experience means integrating top of the range amenities and has given rise to some of the most beautiful, otherworldly and extravagant casinos in the world.

However, with extravagance comes expense. Many of the world’s top casinos are now, in essence, self-contained villages. From hotels and aquariums to full theatres and Michelin-starred restaurants, every new feature racks up the cost of an already pricey endeavor.

So, how much does it cost to build (and play) at a world-class casino nowadays?

Here is a look at the top 5 most expensive casinos in the world:

5) Cosmopolitan – Las Vegas, USA

Cost: $3.9 billion

Opened: 2010

Casino size: 100,000 sq ft

Like most of the resorts on the Strip, the Cosmopolitan isn’t a standard hotel: it also has retail and restaurant space, a full theatre, two nightclubs and a sizable convention centre. All of these features helped rack up the hefty price tag.

We might be biased, but we think the Cosmopolitan’s casino is the highlight of it all. It has floor-to-ceiling glass walls and offers breathtaking views of the Las Vegas Strip. With plenty of tables, 1,300+ slots games and a full sportsbook, they have everything you need for a fantastic gambling session. Better still, they cater to players of all budgets, with low-stakes slots bets starting at just $0.01. The Cosmopolitan also runs casino events every month or so which are a great place to meet fellow gamblers.

4) Resorts World Las Vegas – Las Vegas, USA

Cost: $4.3 billion (expected)

Opened: 2021 (expected)

Casino size: 117,000 sq ft

Following the success of their Singapore Resorts World, Genting Group decided to build another on the Las Vegas Strip. Work on the Vegas site began in May 2015. The hotel and casino is expected to open this summer, though no date has been set due to the ongoing effects of the COVID-19 pandemic.

While we don’t know exactly what the casino will include yet, the resort is said to be Chinese-themed.

3)  Resorts World Sentosa – Sentosa Island, Singapore

Cost: $4.93 billion

Opened: 2010

Casino size: 160,000 sq ft

Resorts World lives up to its name. As well as holding one of Singapore’s two casinos, it also houses a theme park, a shopping mall, four hotels, an aquarium and a waterpark. Oh, and you can swim with dolphins too.

The Casino at Sentosa operates 24 hours per day and is home to around 450 table games, from classics like poker and blackjack to traditional Asian games such as Si Ki Pi. There are also more than 2,400 slots games. While Singaporeans have to pay a fee to visit, foreign citizens can enter for free.

2) Marina Bay Sands – Downtown Core, Singapore

Cost: $6.88 billion

Opened: 2010

Casino size: 161,000 sq ft

The most expensive stand-alone casino in the world, the eye-watering cost of developing the Marina Bay Sands has a lot to do with the high cost of land in Singapore. That said, the building is still a marvel. Highlights include 2,560+ hotel rooms, a convention centre, a museum, six celebrity chef restaurants, a full theatre, a shopping mall, the world’s largest elevated swimming pool, art and science exhibits, and most importantly, the world’s largest atrium casino!

The casino has around 600 tables and 1,600 slots spread over four stories. There are 13 types of table games to enjoy including baccarat, blackjack and poker. Like the Sentosa Casino, the Marina Bay requires permanent residents of Singapore to pay an entry levy.

1) ARIA Resort & Casino – Las Vegas, USA

Cost: $9.2 billion

Opened: 2009

Casino size: 150,000 sq ft

Formerly known as CityCentre, developers at MGM have since moved towards the ARIA branding. ARIA is the most expensive privately-funded development in US history. While the initial estimate for the project was around $4 billion, rising construction costs, design changes and concerns about worker safety pushed the price tag up dramatically.

That said, the ARIA is simply incredible. The 16.8 million sq ft development is more or less a bustling mini city, with 42 restaurants, 4 hotels and 2,400 residential properties. It also contains a public art collection valued at $40 million, a five-star salon and spa, and a tram connecting it with the Park MGM and the Bellagio.

The ARIA boasts a staggering casino floor holding upwards of 2,000 games, with separate high stakes rooms for table games and slots. If you decided against taking a seat at one of the 24 poker tables, you could always head over to the sportsbook where up to 200 live events are shown on 220” TV screens.
