Bloomberg media bias rating is Center.

Bloomberg was intitially rated as having a lean right media bias, but after a majority of people disagreed, its AllSides Bias Rating™ was changed to center in July of 2014. A small majority of approximately 3000 users agree with this rating. The average bias rating among those who disagree is 65.5, just within the range of a lean left bias. This is not enough evidence, however, to change Bloomberg's rating. Bloomberg was also given a center rating in an October 2013 blind survey, with a majority of people rating it as center. 

More on Bloomberg  

Bloomberg L.P. is a privately held financial, software, data and media company founded in 1981 in New York City. It initially began as a computerized system founded by Michael Bloomberg with the help of Thomas Secunda, Duncan MacMillan, and Charles Zegar, designed to provide real-time market data and analytics to firms on Wall Street. With the help of an ownership investment by Merill Lynch, the company was able to develop the Bloomberg terminal computer system in 1983. 

Bloomberg currently provides news in a variety of formats, including a wire service, a global television network, digital websites, a radio station, newsletters and magazines. With a focus on business and economics-related topics, Bloomberg News has redefined itself to become the “chronicle of capitalism,” as editor-in-chief John Micklethwait indicated in 2015. Bloomberg’s main source of revenue remains the Bloomberg Terminal, which offers financial software tools to companies and organizations on Wall Street.

The AllSides Media Bias RatingTM reflects the average judgment of the American people. We don't use a convoluted mathematical or artificial intelligence model, but instead have regular people representing the broad spectrum of Americans blindly rate the bias of articles. That produces a fair, verifiable bias rating.
