Miriam Adelson: The Billionaire Physician Shaping US-Israel Relations

Dr. Miriam Adelson has emerged as one of the most influential billionaires in American politics and philanthropy. Born in Tel Aviv in 1945, this Israeli-American physician has transformed from a dedicated medical researcher into a political kingmaker worth an estimated $40.5 billion. Her journey from treating addiction patients to owning the Dallas Mavericks represents one of the most remarkable stories of wealth, influence, and political power in modern America.

Early Life and Medical Career Foundation

Miriam Farbstein was born to Polish Holocaust survivors who fled to Mandatory Palestine before the Nazi regime could claim them. Her father, a prominent member of the left-wing Mapam party, owned several movie theaters in Haifa during the 1950s. This early exposure to both political engagement and business acumen would later shape Miriam's multifaceted career.

After completing her mandatory military service as a medical officer, Adelson pursued excellence in academia. She earned a Bachelor of Science in microbiology and genetics from Hebrew University of Jerusalem, followed by a medical degree from Tel Aviv University, graduating magna cum laude. Her specialization in addiction medicine at Rockefeller University in 1986 marked the beginning of her lifelong commitment to substance abuse research.

Meeting Sheldon Adelson: A Life-Changing Partnership

The trajectory of Miriam's life changed dramatically in 1989 when she met casino mogul Sheldon Adelson on a blind date. Their 1991 marriage created one of the most powerful political and business partnerships in modern history. Together, they built not just a casino empire but also established themselves as the Republican Party's most generous benefactors.

The couple's first major philanthropic venture came in 1993 with the opening of the Adelson Clinic in Israel, specializing in substance abuse treatment using medically assisted detox techniques. A second location opened in Las Vegas in 2000, cementing their commitment to fighting addiction through both their personal resources and Miriam's medical expertise.

Building a Media and Business Empire

Following Sheldon's death in 2021, Miriam inherited control of Las Vegas Sands Corporation, making her one of the world's wealthiest women. However, her influence extends far beyond casinos. As publisher of Israel Hayom, Israel's most widely read newspaper, she wields significant media influence in the Middle East.

Her business acumen reached new heights in December 2023 when she purchased a controlling 69% stake in the Dallas Mavericks NBA franchise alongside her son-in-law Patrick Dumont. This acquisition not only diversified her portfolio but also positioned her as a major force in American sports entertainment.

Political Influence and Trump Connection

Miriam Adelson's political donations have reshaped Republican politics since the 2010 Citizens United ruling. Her $284 million in lifetime political contributions actually exceed her late husband's $273 million total, dispelling the common misconception that she was merely following his lead.

Her relationship with Donald Trump has been particularly significant. The Adelsons provided the largest donations to Trump's 2016 campaign, presidential inauguration, Mueller investigation defense fund, and 2020 campaign. In 2024, Miriam contributed $106 million to Trump's re-election effort, making her the third-largest donor to his campaign.

Trump's recognition of her influence culminated in 2018 when he awarded her the Presidential Medal of Freedom, citing her contributions to addiction research and medical philanthropy. During his recent Knesset address, Trump publicly acknowledged her role in shaping his Israel policies, including moving the US embassy to Jerusalem and recognizing Israeli sovereignty over the Golan Heights.

Championing Israel and Jewish Causes

Adelson's political donations are deeply intertwined with her commitment to Israel and Jewish causes. Through the Adelson Foundation, she distributes $200 million annually to Jewish and Israeli organizations - the largest private foundation dedicated to these causes. Her support extends from Birthright Israel, which has received over $250 million from the Adelsons, to controversial settlements in the West Bank.

Her advocacy for Israeli settlement expansion has drawn both praise and criticism. She donated $25 million to Ariel University's medical school in the West Bank and $6 million to HaShomer HaChadash, a volunteer militia supporting settler security. These donations reflect her belief in what she terms "strengthening settlers in Judea and Samaria."

The Maccabee Task Force Leadership

As president of the Maccabee Task Force, Adelson leads efforts to combat the Boycott, Divestment and Sanctions (BDS) movement on college campuses. Her support totaling over $70 million has made this organization a powerful force in shaping campus discourse about Israel. The organization focuses on spreading pro-Israel sentiment among young Americans, though Adelson maintains a low public profile in this role.

Net Worth and Global Influence

Forbes estimates Adelson's net worth at approximately $35 billion, making her the richest Israeli and among the ten wealthiest women in America. The Bloomberg Billionaires Index places her even higher at $40.5 billion as of August 2025, ranking her as the 48th richest person globally.

Her wealth stems primarily from her majority ownership in Las Vegas Sands, but her diversified holdings include media properties, sports franchises, and extensive real estate investments. This financial power translates directly into political influence, making her one of the most sought-after donors in Republican politics.
