Bloomberg L.P.

• 1. Introduction

  ›

  Bloomberg L.P. began not with a vision statement or a venture capital pitch, but with a termination check. In 1981, when Salomon Brothers was acquired, Michael Bloomberg walked away as a general partner with a $10 million partnership settlement. That single payout became the seed money for one of the most influential financial information companies in the world. The question worth asking is how a man handed a buyout turned that money into a company now valued in the tens of billions, spanning television, radio, print, software, and law. The answers lie in a terminal, a radical office culture, and decades of controversial decisions that shaped what Bloomberg L.P. is today.

• 2. The Terminal That Started Everything

  ›

  Before he was handed his $10 million, Michael Bloomberg had already spent years at Salomon Brothers designing computerized financial systems in-house. That experience told him exactly what Wall Street lacked: a machine that could deliver real-time market data, financial calculations, and analytics all in one place. He poured his buyout into building that machine, founding the company under the name Innovative Market Systems, or IMS.

  The Market Master terminal, later renamed the Bloomberg Terminal, hit the market in December 1982. Its first major customer was not a small hedge fund or a regional bank. Merrill Lynch purchased 20 terminals and took a 30 percent equity stake in the company for $30 million, in exchange for a five-year restriction barring Bloomberg from marketing the terminal to Merrill Lynch's competitors. That restriction lifted in 1984, opening the door for broader sales.

  By 2011, the Bloomberg Professional Service accounted for more than 85 percent of the company's annual revenue. A subscription starts at $24,000 per user per year, granting access to real-time financial data, price quotes, news search, and the Bloomberg Messaging Service. The terminal covers both public and private markets globally, making it the financial industry's most deeply embedded data tool.

• 3. Building a Media Empire

  ›

  Matthew Winkler joined Michael Bloomberg in 1990 to co-found Bloomberg Business News, later known simply as Bloomberg News. By 2000, the newsroom had grown to more than 2,300 editors and reporters spread across 100 countries. John Micklethwait took the editor-in-chief post in 2015.

  Bloomberg Television launched in 1994, initially as a subscription service transmitted on DirecTV, running 13 hours a day, seven days a week. The network absorbed the channel space of the defunct Financial News Network and hired most of its former employees. Within years it had entered cable and by 2000 was available to 200 million households worldwide.

  Bloomberg.com went live on the 29th of September, 1993, as a financial portal offering market data, currency conversion, and news. The radio side of the empire traces back to 1992, when Bloomberg purchased New York station WNEW for $13.5 million, converted it to an all-news format, and changed its call letters to WBBR. Bloomberg Markets, a monthly magazine serving finance professionals, launched that same year. Bloomberg Businessweek arrived later, when Bloomberg bought the struggling BusinessWeek from McGraw-Hill in 2009. The magazine had been suffering from declining advertising revenue and limited circulation, and Bloomberg saw it as a way to extend its reach beyond terminal subscribers.

• 4. The Ownership Knot With Merrill Lynch

  ›

  Merrill Lynch's original 30 percent stake in the company came with that five-year marketing restriction, and the relationship grew more complicated over time. In late 1996, Bloomberg bought back one-third of Merrill Lynch's remaining stake for $200 million, a transaction that implied a company valuation of $2 billion.

  Then came the financial crisis of 2008. Facing heavy losses, Merrill Lynch agreed to sell its remaining 20 percent stake back to Bloomberg Inc. for a reported $4.43 billion. That deal placed Bloomberg L.P.'s total valuation at approximately $22.5 billion, a figure that illustrates how dramatically the company had grown from its origins as a one-product terminal business. Michael Bloomberg, the majority owner, had turned a $10 million buyout into a company worth more than twenty times that sum in equity alone.

• 5. Leadership Transitions

  ›

  Michael Bloomberg served as both chairman and CEO from the company's founding in 1981 through 2001. When he chose to run for Mayor of New York against Democrat Mark Green, he handed the CEO role to Alexius Fenwick, known as Lex. Fenwick held that post until 2008, when he moved to lead Bloomberg Ventures, the company's new venture capital division.

  Daniel Doctoroff, who had served as deputy mayor in the Bloomberg city administration, was then named president and CEO, a role he held until September 2014. At that point Michael Bloomberg returned as CEO, reclaiming the leadership of the company he had built. He led it again until 2023, when Chief Product Officer Vlad Kliatchko became CEO and Chief Operating Officer Jean-Paul Zammitt became President.

  The chairmanship followed its own trajectory. Peter Grauer became chairman in 2012, a role he held until 2023 when Mark Carney, the former central banker, took over. Carney did not hold the position long. He resigned from his chairmanship shortly before becoming the Prime Minister of Canada.

• 6. A Portfolio of Acquisitions

  ›

  Bloomberg's growth through acquisition followed a clear logic: buy data, buy reach, buy regulatory infrastructure. In August 2011, the company paid $990 million for the Bureau of National Affairs, an Arlington, Virginia-based publisher of more than 350 specialized news and information products covering areas from corporate law to environmental health and safety.

  In 2009, Bloomberg purchased New Energy Finance, a United Kingdom-based data company focused on energy investment and carbon markets research. Michael Liebreich had founded it in 2004; he stayed on as CEO until 2014, then remained as chairman of the advisory board. Renamed Bloomberg New Energy Finance, or BNEF, the unit expanded to cover renewable energy, advanced transport, digital industry, innovative materials, sustainability, and commodities. Its analysts, covering six continents, publish more than 700 research reports a year.

  On the 16th of December, 2015, Barclays agreed to sell its index business, Barclays Risk Analytics and Index Solutions Ltd, to Bloomberg for 520 million pounds, roughly $787 million. The acquired business was renamed Bloomberg Index Services Limited. In May 2012, Bloomberg had also acquired Dublin-based software provider PolarLake to launch an enterprise data management service, and on the 9th of July, 2014, it acquired RTS Realtime Systems, a global provider of low-latency connectivity and trading support services.

• 7. Controversy and Legal Battles

  ›

  Bloomberg L.P. has faced a sustained pattern of legal disputes involving gender discrimination and workplace misconduct. In 1997, former sales executive Sekiko Sakai Garrison filed a lawsuit alleging sexual harassment and wrongful termination, claiming that Michael Bloomberg told her to "Kill it!" when she revealed she was pregnant, and added "Great! Number 16," referring to the count of pregnant women or those on maternity leave at the company. The company did not admit wrongdoing but settled out of court in 2000.

  In September 2007, the Equal Employment Opportunity Commission filed a class-action lawsuit on behalf of more than 80 female employees alleging discrimination against women who took maternity leave. Judge Loretta A. Preska of the Southern District of New York dismissed the charges in August 2011, finding insufficient evidence. Preska dismissed a related EEOC lawsuit on behalf of 29 pregnant employees in September 2013.

  Separate from workplace discrimination cases, Bloomberg also pursued legal transparency from the federal government. The company brought suit against the Board of Governors of the Federal Reserve System to force disclosure of lending records during the 2008 financial crisis. Bloomberg won at trial, the Second Circuit ruled in its favor in March 2010, and in March 2011 the Supreme Court let that ruling stand, compelling the Fed to release details of its bailout programs.

  A different kind of scandal unfolded internally between 2010 and 2017, when a pay-to-play scheme involving Turner Construction executives and Bloomberg executives led to corruption charges. In July 2020, construction manager Michael Campana was sentenced to two years in prison for tax evasion on $420,000 in bribes. Anthony Guzzone, Bloomberg's Director of Global Construction, pleaded guilty on the 29th of September, 2020, to evading taxes on over $1.45 million in bribes; he had accepted more than $5.1 million in total and was sentenced in January 2021 to three years and two months in prison.

• 8. Scale and Structure Today

  ›

  Bloomberg L.P. remains privately held, the majority owned by Michael Bloomberg. As of 2019, the company operates across 176 locations with nearly 20,000 employees. Its headquarters sits at 731 Lexington Avenue in Midtown Manhattan, a building informally known as Bloomberg Tower, where the company occupies 900,000 square feet at the base. Additional New York office space includes 400,000 square feet at 120 Park Avenue and more than 924,000 square feet at 919 Third Avenue. Bloomberg London serves as the European headquarters.

  Inside those offices, the culture is deliberately non-hierarchical. Executives share space with everyone else, seated at identical white desks each equipped with a custom-built Bloomberg computer terminal. Overhead rows of flat-panel monitors display news, market data, weather, and customer service statistics.

  Bloomberg Beta, the company's venture capital fund founded in 2013 with $75 million in capital, operates out of San Francisco, investing in areas aligned with Bloomberg's broader interests. The Bloomberg New Economy Forum, launched in 2018 in Singapore as an invitation-only event for executives, government officials, and academics, counts 3M, ExxonMobil, Microsoft, HSBC, and Mastercard among its founding partners. The 2024 Russian prisoner exchange surfaced a more contentious dimension of Bloomberg's scale: Bloomberg News broke a news embargo on information provided by the White House while the exchange was still in progress, drawing criticism from other publications including the Wall Street Journal for potentially jeopardizing the event.
