Prince Alwaleed bin Talal, who sits at the helm of Kingdom Holding, is understood to have held talks with at least one of Twitter’s co-founders about acquiring part of their shareholding in the microblogging site.

If a deal between them is confirmed, it would add Twitter to the portfolio of companies part-owned by one of the world’s wealthiest investors, although I should caution that it’s possible that Prince Alwaleed might yet opt against acquiring the shareholding. My sources tell me a shareholding of between $200m and $300m has been examined by Kingdom Holding, which after Twitter’s recent fundraising would equate to about 3 per cent of the company.

It’s unclear whether Kingdom Holding has already acquired Twitter shares or whether the vehicle is simply in discussions with Biz Stone and Evan Williams, the founders. Twitter declined to comment.

In August, Twitter said it was raising new money from investors to fund its expansion in the following message posted on its site:

“Twitter continues to grow around the globe at a record pace. Just a year ago, we delivered 65 million Tweets a day. Today, we generate over 200 million Tweets per day. One year ago, there were approximately 150,000 registered Twitter apps. Now, there are more than one million that connect to Twitter. And our team has grown from 250 people to more than 600 in the past 12 months.
