It was reported yesterday that Bloomberg, although not having reached a decision, was giving serious consideration to the idea of selling the company, which is centred around providing screen-based financial information to Wall Street.
The £6.9bn bid by Thompson, which owns a rival screen-based business to Bloomberg, is thought to be only half of what Bloomberg is understood to want for the business, which he owns 72% of.
There could be other bidders. Merrill Lynch, which owns 20% of Bloomberg, has been linked with a possible bid, as has Pearson, which owns the Financial Times.
Talking to the New York Post, a spokesman for Bloomberg said, "We've had no talks with Thomson. We're not for sale."
Since beginning his bid to become mayor of New York city, day-to-to-day running of the company has passed to Lex Fenwick, chief operating officer, who is expected to now succeed Bloomberg as CEO.
Speculation has been rife that a sale was in the offing since Bloomberg's surprise candidacy was declared. As mayor, he is prohibited from running a business that does business with the city.
