Apple’s market cap reached $800bn for the first time on Monday, prompting suggestions that the tech giant could soon become the world’s first trillion dollar company.

Brian White, an analyst at investment banking firm Drexel Hamilton said Apple has “proven its resilience through its unique ability to develop hardware, software and services that work seamlessly together”.

He boosted the company’s price target to $202 a share — the highest expectation of Wall Street’s tech industry watchers.

While the first company in the world to hit the $1trn valuation mark was oil giant PetroChina back in 2007, we don’t really think that counts, and neither should you.

To put the trillion dollar figure into perspective, in 2012, only 15 economies in the world had gross domestic product (GDP) exceeding $1trn.

All the gold mined in the world in a year is worth about $115bn.

Verdict takes a look at some of the biggest companies expected to reach the trillion dollar mark in the near future, giving ratings out of 10 as to how likely each company is to hit the target.

Amazon

Amazon, the US e-commerce website founded by Jeff Bezos in 1994 is currently valued at $455bn.

The company’s stock price has increased by 48 percent over the past year, and is now trading at a record high of more than $948 a share.

“Amazon is likely to be one of the first trillion-dollar market cap companies; it’s just a question of when, not if, in our view,” a Barclays equity research team led by Ross Sandler said in March. “Amazon is arguably the best story in the space, with the most open-ended growth opportunity and most highly functional organisation.”
