Twitter is nu $10 miljard waard

Twitter Inc. was valued at almost $10 billion by one of its investors, up about 10 percent from a previous estimate, indicating shares are appreciating ahead of a possible initial public offering for the microblogging service. GSV Capital Corp. (GSVC) owns 1.9 million shares of Twitter valued at $35.2 million, or about $18.50 a share, the firm said in a May 8 filing. Based on a fully diluted share count of almost 530 million, that makes the company worth about $9.8 billion.

Twitter is becoming more valuable as the San Francisco-based social website boosts revenue from advertising and moves closer to a predicted IPO. In January, Twitter was valued at about $9 billion when a fund managed by BlackRock Inc. (BLK) bought stock from employees, up from the $8 billion valuation in a 2011 investment round led by DST Global, people with knowledge of the matter have said.
