Romanian National Among 125 Billionaire Immigrants in the U.S.
125 Immigrant Billionaires Living in the United States in 2025
In 2025, a record number of 125 foreign-born American citizens have amassed fortunes exceeding $1 billion, collectively holding approximately $1.3 trillion in wealth[1]. These billionaires hail from 41 different countries, with India, Israel, and Taiwan leading the count[1][5].
Among the top immigrant billionaires in the U.S. are Elon Musk, Sergey Brin, and Jensen Huang. Musk, born in South Africa, leads the list with an estimated net worth of around $393.1 billion, known for his companies Tesla, SpaceX, Neuralink, The Boring Company, and xAI[2][3][4]. Brin, co-founder of Google, has an estimated net worth of about $139.7 billion[4]. Huang, born in Taiwan, is the founder and CEO of Nvidia, with a significant wealth arising from AI chip demand and technology[3].
Other notable names include Ion Stoica, a Romanian billionaire with an estimated net worth of approximately $2.5 billion. Stoica is the founder and executive chairman of Databricks, a San Francisco-based company specializing in big data management and artificial intelligence[6]. Stoica, who currently resides in Berkeley, California, is the only Romanian on Forbes' list of immigrant billionaires living in the United States[7].
Before founding Databricks, Stoica co-founded the video streaming startup Conviva[8]. Investors have valued Databricks at USD 62 billion in 2021[9]. Stoica also serves as a computer science professor at UC Berkeley[10].
Three of the 10 richest people in America (and in the world) are immigrants, including Musk and Stoica. However, Stoica is not included in the Forbes list of immigrant billionaires living in the United States, despite his wealth and contributions[7].
This year, a record number of 125 foreign-born American citizens are billionaires and live in the United States[1]. These individuals represent a wide array of industries, mostly concentrated in technology, automotive, aerospace, and AI sectors[2][4].
