Uber is going public.

Uber, as you probably know, is a popular ridesharing company. It allows you to fetch a personal driver using your smartphone.

It's a truly revolutionary company… and one of the world's most valuable.

During its last capital raise in August, Uber was valued at $76 billion. That's far more than General Motors, Ford, and Tesla are worth.

And Uber isn't even profitable. It lost $1.1 billion last quarter. So we're talking about a serious valuation here.

But the company could soon be worth a lot more than that…

• Uber filed paperwork for an initial public offering (IPO) two weeks ago…

An IPO is when a private company offers shares to the public for the first time.

Now, we don't know exactly when Uber's IPO will happen… But many people believe it will be as soon as April 2019. Previously, Uber planned to go public in the fall of 2019.

So it just bumped up its IPO date by two quarters.

According to The Wall Street Journal, Uber could go public at a $120 billion valuation. That's far more than what the company was valued at just four months ago.

At that number, Uber would only need to offer 21% of its shares to become the biggest IPO ever.

And I imagine many investors will buy Uber's stock the second it starts trading. But I'd steer clear of this IPO for a simple reason.
