How Did the Adelson Family Become So Rich?
Sheldon Adelson built his fortune through conventions, casino development, and international resort investments.
His early success came from COMDEX, a major computer industry trade show.
In 1989, Adelson and his partners acquired the Sands Hotel and Casino in Las Vegas.
He recognized the opportunity to attract convention visitors during weekdays, when traditional leisure travel was often slower.
The Sands Expo and Convention Center became an important part of that strategy.
Building The Venetian
The original Sands Hotel was demolished in 1996 to make room for The Venetian Resort.
The Venetian opened in 1999, bringing luxury suites, restaurants, shopping, and convention facilities together in one property.
The resort helped establish a business model combining entertainment, hospitality, conventions, and casino gaming.
Las Vegas Sands later expanded that model internationally.
How Las Vegas Sands Expanded Into Asia
International expansion became a major source of the Adelson family’s wealth.
Las Vegas Sands entered Macau after the region opened its casino market to additional operators.
Sands Macao opened in 2004, followed by The Venetian Macao in 2007.
The company also developed other integrated resorts along Macau’s Cotai Strip.
In Singapore, Las Vegas Sands opened Marina Bay Sands in 2010.
Today, its major gaming operations are concentrated in Macau and Singapore rather than Las Vegas.
The Adelson family’s controlling ownership stake connects its wealth to these international properties.
Does the Adelson Family Still Own The Venetian?
No. Las Vegas Sands completed the sale of its Las Vegas properties on February 23, 2022.
The transaction was valued at approximately $6.25 billion.
The sale included:
- The Venetian Resort
- The Palazzo
- The Venetian Expo
Apollo Global Management acquired the resort’s operating business, while VICI Properties purchased the real estate.
Despite the sale, Las Vegas Sands remains headquartered in Las Vegas.
The company has shifted its casino operations toward its Asian markets.
Why Did the Adelson Family Buy the Dallas Mavericks?
In December 2023, the NBA approved the sale of controlling ownership of the Dallas Mavericks to the Adelson and Dumont families.
The ownership group includes Miriam Adelson, her daughter Sivan Dumont, and son-in-law Patrick Dumont.
Patrick Dumont serves as the Mavericks’ governor and is a senior executive at Las Vegas Sands.
The acquisition expanded the family’s business interests into professional basketball.
It also created a major investment outside the casino resort industry.
However, the Mavericks purchase does not mean the family owns an NBA franchise in Las Vegas.
Other Richest Families in Las Vegas
The Adelsons are not the only wealthy family connected to the city’s gaming industry.
| Family or Individual | Main Source of Wealth |
|---|---|
| Adelson Family | Las Vegas Sands |
| Frank & Lorenzo Fertitta | Station Casinos, UFC |
| Boyd Family | Boyd Gaming |
| Phil Ruffin | Casino Resorts, Real Estate |
| Derek Stevens | Downtown Las Vegas Casinos |
The Fertitta Family
Brothers Frank Fertitta III and Lorenzo Fertitta built substantial wealth through Station Casinos and their investment in the UFC.
They helped develop the local casino market with properties including Red Rock Resort and Green Valley Ranch.
The brothers sold the UFC in 2016 in a transaction valued at approximately $4 billion.
The Boyd Family
The Boyd family’s casino business traces back to Sam Boyd, who helped establish Boyd Gaming.
The company operates gaming properties in Las Vegas and other regional markets.
Unlike Las Vegas Sands, Boyd Gaming continues to own and operate several Nevada casinos.
Is Miriam Adelson the Richest Person in Nevada?
Miriam Adelson is among Nevada’s wealthiest people, but Nevada’s broader billionaire rankings can include technology founders and investors with residences elsewhere in the state.
Forbes ranked Adelson and her family as the wealthiest Nevadans in its September 2026 Forbes 400 reporting.
However, billionaire residence classifications and real-time rankings can change.
For accuracy, it is better to describe the Adelsons as the richest family associated with Las Vegas casino wealth rather than claiming they are permanently the wealthiest Nevada residents.
Conclusion
The Adelson family remains one of the most influential and wealthiest families connected to Las Vegas. Its fortune, estimated at approximately $32 billion in November 2026, comes primarily from Las Vegas Sands and its international casino operations. Sheldon Adelson helped transform the city’s convention and luxury resort businesses before expanding into Macau and Singapore. Although the family no longer owns The Venetian, its business interests remain substantial, including its investment in the Dallas Mavericks.
