Yahoo made $9.4 billion by selling 140 million shares in Alibaba, according to a new SEC filing. Never have so many billions seemed so doomed.

What do we do if Evan Spiegel wasn't just arrogant, but right? What if Snapchat turned down $3 billion in order to someday make much, much more? A new report out of Bloomberg says the app's valuation is in the stratosphere.

Alibaba filed for a U.S. IPO that could value the Chinese e-commerce giant more than Amazon or Facebook. CEO Jack Ma warned his employees, whom he calls Aliren (Ali people), about the "unparalleled ruthlessness and pressure," that awaits.

It looks like all that synergy wasn't enough to help Marissa Mayer steer Yahoo in a more promising direction. Despite hyping improved ad technology at CES, with revenue down, the ship is staying afloat thanks mostly to equity in Alibaba.

While Alibaba plans a possible IPO on NASDAQ or the NYSE, founder Jack Ma is taking selfies with prime minister David Cameron. Hearts and minds, people.
