Amazon.com’s (AMZN) shares reached record numbers this week surpassing a market capitalization of $900 billion for the first time, thanks to its annual shopping event known as Prime Day.

Amazon’s market value hit $902 billion on Wednesday as the company’s stock briefly touched $1,858.88, Reuters reports. The Seattle-based company saw its success after its 36-hour Prime Day event on Monday, its biggest to date. Within that time, Amazon.com sold than 100 million products worldwide and shoppers spent $4.2 billion, up 33 percent from a year ago, according to estimates from Bloomberg.

All this despite the site suffering a series of technical glitches Monday afternoon that stopped some customers from checking out purchased items or searching for more deals. However, Amazon's third-party marketplace sales were up around 90 percent during the first 12 hours of the event from a year ago, CNBC reports.

"We know there were some disappointed customers and we regret any bad experience, even for just one customer," an Amazon spokeswoman said. "Fortunately, many Prime members were able to access our deals – that’s apparent in the numbers we’re seeing. And we have some key learnings for next year."

Meanwhile, Amazon founder Jeff Bezos’ net worth skyrocketed to a staggering $150 billion this week, making him the richest man in modern history. The 54-year-old saw his wealth jump as Amazon’s market capitalization rose. As of 2017, he owned 16.4 percent of the company’s stock, Bloomberg reports

Bezos started Amazon in his Washington home in 1994. Since then, the company has signed up over 100 million people for its Prime membership, which offers access to music and movie streaming and discounted shipping rates. When the company’s IPO went public in 1997, Bezos had a net worth of $1.6 billion.

The New Mexico native reportedly became the richest man in the world on July 27, 2017, when his net worth was estimated at over $90 billion. Behind him is Microsoft founder Bill Gates, whose net worth is listed at $95.5 billion, then investor Warren Buffet with $82.6 billion.
