I posted this yesterday but Yahoo removed it because of it's accuracy. Yahoo and Alibaba Group have come to an agreement for Yahoo to sell Alibaba Group 15% out of their 40%(fully diluted) stake. The deal will include an announcement of an Alibaba Group IPO in early 2013. Jack Ma will pay $5.5 billion for the 15% stake.
You and your sources are the real deal. Funny how Yahoo deleted your original post breaking this news. That was a sure sign that your sources had it right. Thanks for letting us know before Kara Swisher.
