Nvidia's staying power is the $2 tn question

It surpassed market values of both Amazon.com and Alphabet last week

Nvidia's next trillion dollars is proving easier than the first.

That doesn't exactly put the ascendant chip maker on Easy Street.

It became the first semiconductor company worth $1 trillion about eight months ago-not long after its 30th birthday. The stock's momentum has continued; Nvidia is now worth just under $1.8 trillion and is the third most valuable U.S. company, after Microsoft and Apple.

It surpassed the market values of both Amazon.com and Google parent Alphabet last week, businesses with far more revenue that share two notable things in commona vital need for Nvidia's chips to power their growing ambitions in artificial intelligence and capital budgets of tens of billions of dollars annually to put toward the effort.

Just how many billions will become abundantly clear Wednesday, when Nvidia reports its fiscal fourth-quarter results.
