Quartz: This Saudi prince now owns more of Twitter than Jack Dorsey does. “A Saudi prince has increased his holdings in Twitter, making him the company’s second largest shareholder. Prince Alwaleed Bin Talal Bin Abdulaziz Alsaud, who in 2011 invested $300 million in the social network, now owns 34.9 million shares of Twitter’s common stock, according to a new regulatory filing (pdf).” That’s almost 5.2% of the company. Dorsey owns 3.2% of the company. Ev Williams owns more than either of them.
