Uber, the transportation-on-demand behemoth, today filed its much-anticipated updated S-1, where it announced that it would be pricing its initial public offering at $44-50 per share. Selling 180 million common shares, Uber plans to raise between $7.9 billion and $9 billion ahead of its public debut on the NYSE, valuing it at $84 billion — squarely in the middle of the $80-90 billion that was projected as late as yesterday. With the greenshoe, shareholders selling shares in the IPO, it could raise as much as $10.4 billion.
