Apple became the first U.S. company to reach a $2 trillion valuation on Wednesday. What's more stunning than the sheer enormity of the number, though, is how the tech company did it: While Apple first reached $1 trillion in August 2018, its valuation had been relatively stagnant until recently. According to The New York Times, Apple's value was under $1 trillion as recently as mid-March, when the stock market fell due to coronavirus concerns. 

Since then, however, Apple, Microsoft, Amazon, Alphabet and Facebook have grown by close to a combined $3 trillion due to a flood of new investors, even while the global economy has shrunk at an alarming rate.
