Twitter's mysterious outside shareholder

Rizvi and its funds have a stake that will be worth $1.7 billion if Twitter's shares are priced at $20—the top of its target range. The firm started investing in the social network at the end of 2010, and its funds have since drawn big-name investors, including JPMorgan, which through its investments will own a 9 percent post-IPO stake in Twitter.
Saudi Prince Alwaleed bin Talal also invested in Twitter through Rizvi, and his Kingdom Holding owns more than 20 million shares.
