Google on Thursday, January 16, joined the likes of Apple, Microsoft and Amazon as a $1 trillion company.

The search engine company was able to record the milestone achievement after its parent company, Alphabet ended the day’s trading at $1,451.70 per share, up 0.87 percent.

With Thursday’s achievement, Google became the fourth S&P 500 component to top the lofty level.

Business Insider reported that while Apple and Microsoft are still valued at more than $1 trillion, Amazon which was the second US firm to ever hit the $1 trillion level back in September 2018 has since fallen below the number.

This is the first time that three American companies are worth at least $1 trillion at the same time.

The most valuable company on the planet is still oil giant Saudi Aramco, who went public last month at a valuation of $2 trillion and is currently worth around $1.8 trillion.

Alphabet’s record market valuation came after a historic change in leadership at the company.

Recall that Sundar Pichai became the CEO of both Google and Alphabet after co-founders Larry Page and Sergey Brin announced that they would step back from the company which they founded in 1998.
