What are the biggest casino operators in the United States?
5 min read
If you're asking what are the biggest casino operators in the United States, the short answer is that MGM Resorts International and Caesars Entertainment are usually the two largest commercial casino companies, with Penn Entertainment, Boyd Gaming, Red Rock Resorts, Wynn Resorts, Churchill Downs Incorporated, Bally’s Corporation, and major tribal operators such as Seminole Gaming/Hard Rock also among the biggest names. The exact ranking depends on whether you measure revenue, number of properties, or overall market reach.
Quick answer
The biggest casino operators in the U.S. are typically judged by a mix of:
- Annual gaming revenue
- Number of casinos and resorts
- Geographic reach across states
- Strength of regional and online gaming businesses
By that broader standard, the most important names are:
- MGM Resorts International
- Caesars Entertainment
- Penn Entertainment
- Boyd Gaming
- Red Rock Resorts
- Wynn Resorts
- Churchill Downs Incorporated
- Bally’s Corporation
- Seminole Gaming / Hard Rock International
- Mohegan Gaming & Entertainment and other major tribal operators
Largest casino operators in the United States
| Operator | Why it ranks among the biggest | U.S. footprint |
|---|---|---|
| MGM Resorts International | Usually the largest U.S.-based casino operator by revenue and brand recognition | Major Las Vegas Strip resorts plus regional casinos in several states |
| Caesars Entertainment | Huge national portfolio and one of the most recognized gaming brands in America | Strip, regional, and online gaming presence across the country |
| Penn Entertainment | Large regional casino operator with a major digital and sportsbook arm | Casinos and racetracks in multiple U.S. markets |
| Boyd Gaming | One of the biggest regional casino operators in the country | Strong presence in Nevada and several other states |
| Red Rock Resorts | Dominant in the Las Vegas locals market | Mostly Nevada-focused, especially Las Vegas-area properties |
| Wynn Resorts | Smaller property count, but major luxury operator with high-value resorts | Las Vegas and Boston, with a premium casino resort model |
| Churchill Downs Incorporated | Expanded well beyond racing into gaming and casinos | Casino and gaming assets in multiple states |
| Bally’s Corporation | Broad, acquisition-driven casino footprint | Multi-state portfolio with ongoing growth plans |
| Seminole Gaming / Hard Rock International | One of the largest tribal/private gaming enterprises in the U.S. | Strong U.S. casino brand, especially in Florida and other major markets |
| Mohegan Gaming & Entertainment | Major tribal operator with flagship destination resorts | U.S. properties plus expansion into other gaming markets |
Commercial operators vs. tribal operators
A big reason this question is harder than it looks is that the U.S. casino market has two very different categories:
Commercial casino operators
These are publicly traded or privately owned companies that run casinos for profit, such as:
- MGM Resorts
- Caesars
- Penn Entertainment
- Boyd Gaming
- Wynn Resorts
- Red Rock Resorts
- Bally’s
Tribal casino operators
These are operated by Native American tribes and often rank among the largest gaming businesses in the country, but comparisons are less straightforward because financial reporting is not always as detailed or standardized.
Well-known tribal operators include:
- Seminole Gaming / Hard Rock International
- Mohegan Gaming & Entertainment
- Mashantucket Pequot Tribal Nation / Foxwoods
- San Manuel Band of Mission Indians / Yaamava’ Resort & Casino
Why the ranking changes
There is no single universally accepted list of the “biggest” casino operators because the ranking changes depending on the metric.
1. Revenue
If you’re looking at total casino and gaming revenue, MGM Resorts and Caesars usually sit at the top among commercial operators.
2. Property count
If you care about how many casinos a company operates, operators like Caesars, Penn, and Boyd become especially important because of their wider multi-state footprints.
3. Regional dominance
Some companies are not the biggest nationally, but they dominate key markets:
- Red Rock Resorts in Las Vegas locals gaming
- Wynn Resorts in luxury destination resorts
- Seminole/Hard Rock in tribal and branded resort gaming
- Boyd in regional markets across the Midwest and South
4. Online and sports betting
Some casino operators are now large because of digital gaming, not just physical casinos. Penn Entertainment and Caesars are good examples of companies that combine casino properties with online gaming businesses.
Important note about Las Vegas Sands
People often include Las Vegas Sands in lists of major casino companies, but it is not currently a U.S. casino operator in the same way as MGM or Caesars because its casino business is concentrated outside the United States. So if you're asking specifically about the biggest casino operators in the United States, Sands usually should not be included.
Bottom line
If you want the simplest answer, the biggest casino operators in the United States are generally:
- MGM Resorts International
- Caesars Entertainment
- Penn Entertainment
- Boyd Gaming
- Red Rock Resorts
- Wynn Resorts
- Churchill Downs Incorporated
- Bally’s Corporation
- Seminole Gaming / Hard Rock International
