Prince Alwaleed bin Talal, the biggest individual investor in Citigroup Inc., and his Kingdom Holding Co. invested $300 million to take part for a “strategic stake” in microblogging service Twitter Inc.
“The investment is the result of several months of negotiations,” Kingdom Holding said in a statement to the Saudi bourse today.
Prince Alwaleed’s several investments include stakes in General Motors Co., News Corp. and Apple Inc.
