Of the 7,840,000 shares being offered, 3,012,196 are from existing holders, and the balance (4,827,804) are issued. Therefore, post-IPO, LinkedIn will have 94,498,627 + 4,827,804 = 99,326,431 shares outstanding.<p>At a median price of $33 per share, that gives LinkedIn an implied valuation of <i>$3,277,772,223</i>, which isn't as high as I'd expected, given Facebook, Zynga, Groupon and Twitter's recent valuations
