LinkedIn may be the first company to quench investor thirst for the red-hot social networking market.

Despite months of headlines from Facebook, Chicago-based Groupon and Twitter, the company that connects more than 85 million professionals could be first out of the gate. It has been quietly preparing an initial public offering for as early as the first quarter.

LinkedIn has hired Bank of America Merrill Lynch, Morgan Stanley and JPMorgan Chase to advise it after a round of interviews in November. The size of the offering is not known, but it’s expected to be small relative to the company’s valuation. LinkedIn’s implied valuation on the private trading marketplace SharesPost is $2.2 billion.
