But what about the other?Currently, there are no stocks with a $5 trillion market cap or greater. Nvidia (NVDA 3.78%) is valued at $4.3 trillion, and was recently valued at over $5 trillion before pulling back. Following up Nvidia are Apple at $4 trillion, Alphabet (GOOG 3.16%) (GOOGL 3.22%) at $3.7 trillion, and Microsoft at $3.5 trillion. These are the only real candidates that can be worth $5 trillion or more, as Amazon is the fifth-largest company in the world at $2.6 trillion, which means its stock would have to more than double to breach the $5 trillion threshold. So, of these four, which ones could be worth $5 trillion or more in 2026? I think there are only two real answers, and one may surprise you. Image source: Getty Images. Reaching the $5 trillion valuation threshold won't be easy for one of these stocks It should come as no surprise that I think Nvidia will cross the $5 trillion valuation threshold in 2026. It's still growing at a rapid pace thanks to its best-in-class graphics processing units (GPU) technology stack. Demand for artificial intelligence computing power in data centers isn't slowing down, and it is shouldn't for some time. Nvidia believes global data center capital expenditures will reach $3 trillion to $4 trillion by 2030, up from $600 billion in 2025. Should that come to fruition, Nvidia would be a monster performer over the next five years, and 2026 is shaping up to be another phenomenal year. CEO Jensen Huang noted that the company is "sold out" of cloud GPUs, although he didn't elaborate on how far in the future they are sold out. Regardless, demand outpaces supply for its GPUs, which allows it to maintain high prices and lofty profit margins. This will fuel Nvidia's growth in 2026, and Wall Street analysts are expecting 48% growth again in fiscal year 2027 (ending January 2027) after rising a projected 63% in fiscal year 2026 (ending January 2026).

Alphabet was a bit of a laggard in the AI arms race because competitors launched generative AI tools before it did. Furthermore, the initial release of its model was bad and caused several PR nightmares. However, Alphabet has addressed those issues and is now one of the leading providers of generative AI. In addition, Alphabet's core Google search business was spared from being broken up due to monopoly concerns earlier this year, and its future is now much clearer than it was just six months ago.

However, for Alphabet's stock to be worth $5 trillion, it must rise at least 35% from today's levels. Can it do that? Alphabet's earnings growth has been impressive in recent quarters There are a few ways for a stock to rise: growing revenue and earnings, or an increase in valuation. Both of these are reasonable actions for a share price to rise, and Alphabet will likely need a boost from both to cross the $5 trillion threshold. In Q3, revenue rose 16% year over year, and diluted earnings per share (EPS) increased 35%. If Alphabet can keep up its EPS growth, then it could cross the $5 trillion threshold with growth alone. However, I think it could also use some help in the valuation department. Despite growing at the same pace or faster than Apple or Microsoft, Alphabet trades at a discount from a price-to-earnings perspective. GOOGL PE Ratio data by YCharts Should Alphabet's stock receive a 35 times trailing earnings valuation, that would result in 14% growth alone. Alphabet will need all the help it can get to reach a $5 trillion valuation by the end of 2026, but I think it can do it. Even if it doesn't, I think it could easily reach that level by 2027.About the AuthorKeithen Drury is a contributing Motley Fool technology analyst covering AI, semiconductors, cybersecurity, and SaaS stocks.
