Bloomberg L.P.

Bloomberg L.P. is a privately held financial data, software, and media powerhouse headquartered at 731 Lexington Avenue in Midtown Manhattan. Founded on October 1, 1981, by Michael Bloomberg, Thomas Secunda, Duncan MacMillan, and Charles Zegar, with a 12% equity stake from Merrill Lynch, the company started as a single-product venture. Its flagship offering, the Bloomberg Terminal, revolutionized how financial professionals access real-time market data, analytics, and trading tools. The terminal remains the firm's primary revenue driver, used by over 325,000 subscribers at banks, investment firms, and corporations worldwide.

Beyond the terminal, Bloomberg has built a vast media empire. Bloomberg News, launched in 1990, competes with Reuters and the Associated Press in financial journalism, operating more than 150 news bureaus globally. Bloomberg Television provides 24-hour business news coverage, while Bloomberg Radio and digital platforms extend the brand's reach. The company also publishes two magazines: Bloomberg Businessweek and Bloomberg Markets. As of 2025, Bloomberg employs about 20,000 people across 176 offices globally. The firm's influence in finance and media is substantial, though its private status means detailed financials are rarely disclosed. Michael Bloomberg, who served as New York City's mayor from 2002 to 2013, remains the majority owner with an estimated 88% stake, contributing to his net worth of $96 billion.[edit]
