Still, Facebook reached the $200 billion mark in just two years since its initial public offering, faster than Google, Microsoft and Apple, according to Money. It’s also surpassed the value of legacy tech companies like IBM, Intel and Oracle.

Facebook is now No. 18 on the list of U.S. companies by value. For tech companies, it’s No. 5.

But interesting to note: Facebook was also worth much more at the time of its initial public offering than some of its rivals, notes Money. For example, Facebook was valued at $100 million just after its IPO in 2012, while Microsoft was below $1 billion for its IPO in 1986.

Apple tops the charts with a market cap of $587 billion. But it took a while to get there. It first passed $200 billion on March 2010, according to MacRumors, nearly 30 years after its IPO – and around the time it introduced the iPad.

Trailing behind Apple among U.S. tech companies is Google (it’s actually third overall behind ExxonMobil). Google, which took nearly seven years to hit the $200 billion mark after going public in 2004, has a market cap of about $406 billion.

The next tech company to go well beyond the $200 billion mark? Microsoft, which did so in 1998, a little under 11 years after its IPO, according to CNN.

Only two more tech companies rank above Facebook on the list: China Mobile at $263 billion and Verizon at $205 billion, which rank at the No. 9 and No. 17 spots. Facebook rounds out the list at No. 18 currently.
