The Salomon Brothers Severance & The Blind Bond Market
In the summer of 1981, 39-year-old partner Michael Bloomberg was abruptly fired from Wall Street powerhouse Salomon Brothers following its merger with Phibro. Armed with a $10 million equity buyout, Bloomberg surveyed the global financial landscape and noticed a glaring structural absurdity.
Traders were handling hundreds of millions of dollars in corporate and government bonds completely in the dark. Legacy financial information was controlled by slow news ticker services like Dow Jones and Reuters, which delivered delayed headline teletypes on scrolling paper tapes. Valuing a complex Treasury bond required cumbersome physical bond tables, hand calculators, and phone calls to opaque trading desks. Wall Street giants viewed computing as an expensive back-office accounting expense rather than a front-office weapon.
"The best way to protect yourself is to be so valuable that they cannot afford to let you go."
— Michael Bloomberg, Founder of Bloomberg L.P.
The 'Market Master' & The Instant Bloomberg (IB) Chat Monopoly
Michael Bloomberg founded Innovative Market Systems and designed the 'Market Master' terminal—a dedicated computer terminal that did what no machine had ever done: calculate bond yields and duration in real time, chart securities, and deliver live financial news.
In 1982, Merrill Lynch recognized the power of the terminal, ordering 20 units and investing $30 million for a 30% equity stake. But Bloomberg's true asymmetrical masterstroke was network effects: he integrated 'Instant Bloomberg' (IB) chat directly into the machine. Within a decade, IB became the private, encrypted, closed-loop communications highway for every institutional trader, hedge fund portfolio manager, and central banker on earth.
Bloomberg built the most durable B2B software monopoly in history through ironclad commercial discipline: no volume discounts. A firm ordering one terminal pays approximately $30,000/year; a firm ordering 10,000 terminals pays $27,000/year per unit under non-negotiable two-year contracts. To cancel a Bloomberg Terminal means severing a trader from their peer chat network and deal flow—resulting in an institutional retention rate exceeding 98%.
