The industry that produces the most millionaires is the financial services sector. It has been reported as the top industry that has created more millionaires than any other industry globally. Financial services include wealth management, investment banking, hedge funds, insurance, and fintech, which are central to managing and growing wealth worldwide. Following closely, technology is another major industry for creating millionaires, particularly due to its rapid pace of innovation and extensive impact across sectors such as fintech, e-commerce, SaaS platforms, and artificial intelligence. Manufacturing leads in producing the most billionaires over the past decade, but for millionaires specifically, financial services and technology stand out as the primary industries for wealth creation. Summary:

• Financial services industry produces the most millionaires globally.
• Technology industry is the second largest producer of millionaires.
• Manufacturing has created the most billionaires but is not specifically cited as the top for millionaires.
