How Michael Bloomberg Built His Wealth
Michael Bloomberg built most of his fortune by founding Bloomberg LP, a financial data and media company. After being fired from Salomon Brothers in 1981, he used his severance pay to start Innovative Market Systems, which later became Bloomberg LP. The company earns revenue by selling real-time financial data, analytics, and trading tools to banks, hedge funds, and corporations worldwide, and its terminals remain a core source of profit. Bloomberg also owns Bloomberg Media, which operates Bloomberg Television, Bloomberg Radio, and Bloomberg.com, generating additional income from advertising and subscriptions. Forbes profile

How His Wealth Compares
Bloomberg's wealth is largely self-made, built from a single business focused on financial data and media rather than inheritance or family wealth. His ranking among the richest individuals shifts as private company valuations are updated and public markets move, but he remains a top-tier billionaire globally. Bloomberg has pledged the majority of his wealth to philanthropy through the Giving Pledge, with major donations to education, public health, the arts, and climate initiatives.
