Nvidia has officially closed Thursday’s trading session with a market capitalization of $4 trillion, marking a historic milestone for the AI chipmaker and further cementing its position at the heart of the global tech rally.

While Nvidia now ranks alongside Apple and Microsoft in the $3–4 trillion club, what’s striking is how its valuation compares to other well-known tech giants:

• 1.8× Alphabet ($2.17 trillion)

• 4× Tesla ($998.08 billion)

• 17× AMD ($233.74 billion)

• 7× Tencent ($572.77 billion)

• 15.7× Alibaba ($254.45 billion)

• 88.9× JD.com ($45.00 billion)

These comparisons help visualize the scale of Nvidia’s rise, driven largely by its dominant position in the AI hardware sector. Its GPUs underpin many of today’s generative AI systems, from data centers to large-scale model training — a key reason for the surge in investor enthusiasm.

The company’s valuation has multiplied rapidly over the past year amid a broader AI boom. While some analysts warn of overheating in the chip sector, others argue that Nvidia’s leadership position justifies the premium.

“When investors say ‘AI,’ what they really mean is Nvidia,” remarked one market strategist.

As of the close of trading on Thursday, local time, Nvidia stands not only as a chipmaker but as a bellwether of the AI era — its $4 trillion valuation redefining what’s possible in modern tech markets.
