Amazon has become the second company to hit a market value of $1 trillion.
It closely follows Apple, who achieved the record valuation last month.
Retail giant Amazon, meanwhile, hit the landmark earlier today after the Seattle-based company's stock rose 1.7% on the Nasdaq index.
The share price hit a high of $2,050.50 per share, although later fell slightly.
Amazon was founded in 1994, initially as a bookstore before rapidly expanding to sell a vast range of other products.
The company now employees around 560,000 people around the world, and has massively expanded its remit into areas such as video streaming, film and TV production, food, video games, smart devices and web services.
Its subsidiaries include the likes of audio book company Audible, popular streaming platform Twitch and the US supermarket chain Whole Foods.
In the past quarter, the company posted record profits of $2.5bn.
Amazon founder and CEO Jeff Bezos is the world's wealthiest person with an estimated net worth of more than $150 billion.
However, the firm has also faced multiple controversies over the years - most often surrounding working conditions in its distribution centres and its tax bills.
BBC reported last month that the company's UK tax bill fell in 2017, despite a nearly three-fold increase in profits.
US President Donald Trump has sharply criticised the company on a number of occasions.
I am right about Amazon costing the United States Post Office massive amounts of money for being their Delivery Boy. Amazon should pay these costs (plus) and not have them bourne by the American Taxpayer. Many billions of dollars. P.O. leaders don’t have a clue (or do they?)!
