Does Nvidia Deserve Its $4 Trillion Valuation?

On all other fundamentals, Nvidia is the smallest of the Big Tech companies.

Its FY25 revenue was $115 billion, an extraordinary doubling in the last year.

A quick reminder, however, that Apple nearly pulled in an annual profit of $100 billion three years ago.

So why is Nvidia picking up so much steam compared to its more established Big Tech peers?

Stock Prices Are About the Future

Simply put: it’s a reflection of what investors think it can do in the future, not what it’s already done now.

Its chip business is seen as fundamental to the next wave of tech innovation, and there is a great deal of optimism for future growth capacity with growing demand for AI services.

The reasoning thus is that Nvidia will continue to grow at its extraordinary pace, and the stock will only become more expensive in the future.

But, What if...?

However, this optimism brings elevated risk.

The valuation is justified only if Nvidia can maintain its current trajectory and successfully navigate competition, maturation of AI infrastructure, and potential regulatory headwinds.
