Business news provider Bloomberg LP, with a valuation of $35 billion, has been ranked second in Business Insider’s Digital 100, a listing of the world’s most valuable privately held technology companies.

Bloomberg, led by CEO Daniel Doctoroff, had revenues of $7.60 billion last year. “Although Bloomberg is comprised of many different businesses, at its core it is a media company. We give it a healthy 5X multiple on 2011 revenue for a valuation for $35 billion,” Business Insider said.

China’s online marketplace Alibaba, with a valuation of $40 billion, topped the list.

The rankings are based on several metrics, including revenue, users, market opportunities, growth rates and the perception of investors and tech gurus. After the flameout of stocks like Facebook and Zynga, which were privately held and ranked on this list last year, Business Insider said it has, in many instances, “disregarded valuations stamped on recent funding rounds and instead valued companies based on their public comparables.”

The following are the other top New York companies on the list, along with their rankings, valuations and other details:
