This Israeli-American powerhouse didn’t inherit her empire overnight; she crafted it through a blend of medical passion, shrewd business moves, and unwavering philanthropy. From treating addiction in bustling clinics to steering a global casino giant, Miriam’s story is one of quiet strength and bold impact. In this piece, I’ll take you through her remarkable journey, her wealth-building strategies, and the legacy that’s inspiring generations. Let’s explore how this trailblazing doctor turned her talents into a billion-dollar powerhouse.

Early Life: Roots in Resilience and Medicine

Miriam Adelson, born Miriam Farbstein on October 10, 1945, in Tel Aviv during the British Mandate of Palestine, grew up in a family shaped by survival. Her parents fled Poland just before the Holocaust, carrying stories of loss and hope that instilled in young Miriam a deep sense of purpose. Her father, a left-wing activist and theater owner in Haifa, surrounded her with the vibrancy of cinema and community, while her mother nurtured a home filled with intellectual curiosity.

From these roots, Miriam carved her path into medicine. She earned her medical degree from the Sackler Faculty of Medicine at Hebrew University of Jerusalem, specializing in internal medicine and pharmacology. By the 1970s, she had moved to the U.S., where she focused on addiction treatment—a field close to her heart amid rising opioid crises. In 1986, she opened her first clinic in Las Vegas, laying the groundwork for what would become a lifelong mission. These early years weren’t glamorous; they were gritty, hands-on work that honed her empathy and drive. Little did she know, this foundation would propel her into boardrooms and billion-dollar board games.

Meeting Sheldon: A Partnership That Sparked an Empire

Miriam’s life took a transformative turn in 1989 when a blind date introduced her to Sheldon Adelson, the self-made casino mogul behind Las Vegas Sands. They married in 1991, blending her medical expertise with his entrepreneurial fire. Sheldon, already a force in gaming, saw in Miriam a partner who could elevate their shared vision beyond profits—to people and purpose.

Together, they expanded the Adelson Clinics, opening a second location in Las Vegas in 2000. These facilities pioneered medically assisted detox, treating thousands for substance abuse with innovative techniques like methadone therapy. But Miriam’s influence went deeper; she advised on ethical business practices, ensuring Sands’ resorts prioritized employee wellness. Their union wasn’t just romantic—it was a powerhouse alliance that amplified both their strengths. As Sheldon built glittering casinos in Macau and Singapore, Miriam grounded the empire in compassion, proving that true wealth touches lives.

Building the Business Legacy: From Clinics to Casinos

Miriam’s business ascent truly accelerated after Sheldon’s death in 2021. Inheriting a controlling 56% stake in Las Vegas Sands Corp, she stepped into the chairman’s role with steady hands. Today, Sands operates iconic properties like Marina Bay Sands in Singapore and Parisian Macao, generating $11.3 billion in 2024 revenue despite global headwinds. Under her watch, the company navigated post-pandemic recoveries, focusing on Asian markets where gaming thrives.

But Miriam’s legacy isn’t confined to slots and suites. In 2023, she made headlines as the first woman to become majority owner of an NBA team, snapping up the Dallas Mavericks for $3.5 billion—a franchise now valued at $4.7 billion. This bold diversification showcased her eye for growth, blending sports passion with savvy investment. She also owns Israel Hayom, Israel’s top newspaper, using it to champion conservative causes and Jewish heritage.

Her strategy? Strategic patience and people-first policies. While Sands’ stock dipped 80% from its 2021 peak, Miriam’s focus on sustainability and expansion kept the empire humming. From a doctor’s scrubs to a boardroom suit, she’s transformed challenges into chapters of triumph.

These steps highlight how Miriam wove medicine, media, and mogul moves into a seamless legacy.

Philanthropy: Giving Back with Heart and Hustle

Wealth, for Miriam, is a tool for good. Through the Adelson Family Foundation, she’s donated over $500 million to causes close to her roots: addiction research, Jewish education, and Israeli innovation. The Adelson Medical Research Foundation funds breakthroughs in drug rehab, while her support for Birthright Israel has sent 800,000 young Jews on heritage trips.

She’s also a force in politics, shifting from Democrats to Republicans in the 1990s. The Adelsons backed Benjamin Netanyahu’s 1996 campaign and poured $280 million into U.S. GOP efforts. In 2024, Miriam alone donated $100 million to Trump’s bid, advocating for strong U.S.-Israel ties—like recognizing Jerusalem as the capital. Critics call it influence-buying; she sees it as safeguarding her homeland. Either way, her giving isn’t flashy—it’s focused, funding scholarships and clinics that change lives quietly but profoundly.

Net Worth Breakdown: The Numbers Behind the Name

As of October 2025, Miriam’s fortune stands at $40.5 billion, per Bloomberg’s Billionaires Index—up 5.9% year-to-date despite market dips. Forbes pegs it at $32.1 billion, ranking her 56th globally and Nevada’s richest resident. The bulk? Her 54% Sands stake, worth about $17.2 billion in shares, plus the Mavericks’ appreciating value.

Diversification shines: Media holdings like Israel Hayom add cultural clout, while real estate and investments buffer volatility. Here’s a simple table of her wealth sources:

Fluctuations? Sands’ Asia focus weathers U.S. slowdowns, but her steady hand keeps growth humming.

Challenges and Triumphs: The Woman Behind the Wealth

Miriam’s path wasn’t paved with gold. Early clinics faced funding woes, and Sands weathered Macau crackdowns. Post-Sheldon, she battled grief while fending off activist investors. Yet, triumphs define her: Becoming Israel’s richest woman, breaking NBA glass ceilings, and funding medical miracles. At 80, she embodies quiet power— a doctor who heals, a mogul who builds, a philanthropist who lifts.
