The tech juggernaut isn't alone anymore, however, as Amazon has reached $1 trillion valuation.
Just a few weeks after Apple became the world's $1 trillion company, Amazon became the second to reach the historic marker: On Tuesday, as Amazon stock inched higher, the company's market capitalization briefly rose over $1 trillion.
Last month, Apple became the first USA company to become a $1 trillion company.
Starting as a new way to sell books in the early years of the internet, Amazon has grown to an online behemoth and has changed the retail landscape across the world.
Amazon has become the second publicly traded company to be worth US$1 trillion.
It surged past the trillion dollar mark this afternoon, prompting experts so say it could become even bigger than Apple.
Amazon now trades up 74.0 percent for the year to date.
"Every cent they made they put back in the company", said independent technology analyst Rob Enderle.
Amazon's shares debuted at $18 on May 15, 1997. Bezos's fortune was measured at just under $100 billion at the start of 2018, so he is theoretically up more than $66 billion in unrealized gains so far this year.
Investing in warehouses, trucking, drones, shipping and other distribution systems not only enables Amazon to drive down costs they position the company to compete with the likes of FedEx and UPS.
By early afternoon, Amazon's stock was trading at $2,030 per share, up less than 1 percent, putting its market cap at $990 billion.
Critics of the company include US President Donald Trump, who has expressed ire at the Bezos-owned Washington Post newspaper that has published stories the president didn't like.
