Tech giant Apple first breached the $1 trillion market threshold in August 2018, Amazon followed suit a month later, then Microsoft achieved the valuation in April 2019.

Alphabet the parent company of Google, Verily, Waymo and other firms, has now became the fourth U.S. company to reach a $1 trillion market capitalization on Thursday. The achievement comes just over a month after former Google CEO Sundar Pichai took the reins.

Alphabet has doubled its revenue run rate from $1 billion to $2 billion per quarter between February 2018 and July 2019 mostly from Google’s cloud services. Alphabet now sits alongside Apple and Microsoft who both remain above the $1 trillion mark, while Amazon has since fallen below this threshold.
