The 15 Most Valuable Startups in the U.S.

Uber just lapped Facebook. After a new round of investor funding, Uber Technologies Inc. is now valued at close to $51 billion, the highest valuation ever for a venture-backed firm -- a title once held by Facebook. 

Uber isn’t the only tech startup getting sky-high valuations lately. Lodging rental site Airbnb is worth more than $25 billion and Elon Musk’s SpaceX is worth $12 billion and climbing. What’s behind these staggering startup valuations?

In large part, investors are driving the valuation game. More and more investors are trading higher valuations for protections against losses and other advantages. Higher valuations, which help nascent companies build credibility and recruit talent, are typically part of package deals in which the investors receive preferential treatment in the event of IPOs, sales or financial setbacks. The more generous the terms a startup can offer, the higher the valuation it can gain.

Billion-dollar startups are sometimes referred to as “unicorns,” since they are so rare – or at least they used to be. But over the last few years, these unicorns have become more like cattle and sheep, easy to find grazing in the fields of finance. The Wall Street Journal has tracked 108 venture-backed private companies in the billion-dollar startup club, with 74 found in the U.S. tech sector.
