Saudi Prince Alwaleed bin Talal said today that he and his investment firm, Kingdom Holding Co., are purchasing a $300 million stake in Twitter Inc., CNNMoney.com reported. The billionaire prince said the investment was made after “several months of negotiations” and would represent “a strategic stake” in the microblogging service. Though it’s unclear how much control Alwaleed’s investment will provide, the prince’s investment firm looks to become a long-term investor in its portfolio investments and “seeks to work closely with the management of those companies and participate in strategic decisions,” according to its website. With a reported net worth of $21.3 billion, Prince Alwaleed has topped Arabian Business’ Arab Rich list for eight consecutive years, CNNMoney.com said.
