Adelson

Miriam Adelson, with an estimated net worth of around $33 billion as of 2025, made most of her fortune through inheritance and ownership of the Las Vegas Sands casino empire following the death of her husband, Sheldon Adelson, in 2021.

While she is a trained physician and philanthropist, her wealth primarily comes from her controlling stake in Las Vegas Sands, which operates major casino resorts in Las Vegas, Macau, and Singapore.

Miriam Adelson has also become a prominent political donor, especially within Republican and conservative circles in the United States.
