The US stock market’s once again on fire, with the S&P 500 trading near-record levels (above 7,400 points) as technology leaders push the index higher.
Nvidia‘s (NASDAQ: NVDA) been a huge part of that story. The company’s market capitalisation recently passed the $5trn mark and the shares have led chip and artificial intelligence (AI) rallies that are driving investor attention worldwide.
But surely it’s not the only thing moving markets now?
A volatile growth environment
Clearly, AI and chip stocks are the main engine behind today’s gains, with investors piling into firms that supply the data centre hardware behind generative AI applications. Other big winners in this field are AMD and Intel.
“Artificial intelligence headlines this week have offered fresh evidence that investor interest and customer demand remains strong.”

At the same time, markets are watching US Treasury yields and incoming Federal Reserve signals because higher yields could cool the rally by raising discount rates on long‑duration tech profits.
In my opinion, it’s a promising, but fragile, market. A prolonged Middle East conflict has pushed oil prices higher amid Fed inflation worries. Not to mention, the tense Trump/Xi summit which is affecting risk appetite as trade and tech policy remain on the table.
The key question now is: can Nvidia keep markets optimistic?
The factors behind Nvidia’s surge
Nvidia dominated the tech landscape for the past five years but slowed in late 2025. Now, it’s once again hitting new highs as investors pile into the AI hype story.
Several factors are supporting the rally:
-
Fresh demand for AI chips from cloud providers and enterprises.
-
A shortage of top‑end GPUs that supports pricing power.
-
Expectations it’ll continue to convert AI interest into growth.
-
Positive analysis driving momentum in semiconductor names.
The $5trn capitalisation marks a fresh peak among public companies and underlines how central it’s become to the AI narrative.
Plus, its balance sheet gives this fresh rally credibility. It holds very large cash and short‑term investments and has generated exceptionally strong free cash flow in recent periods.
That’ll help fund buybacks and fresh investments without stretching the business — a financial cushion that helps explain why investors are willing to pay a premium.
Let’s take a look at the numbers…
Nvidia’s latest reported results showed revenue up 64.5% year-on-year and 60%+ operating margins well above almost all other tech stocks. The recent resurgence in AI data centre sales is a clear driver.
