Nvidia Crosses $5 Trillion

On 24 April 2026, Nvidia became (for the second time) the most valuable publicly traded company in history. Its stock closed at $208 per share, pushing its market capitalisation past $5 trillion. It is now worth more than Alphabet (Google) and Apple combined, and roughly $1 trillion more than the next largest company on earth.

To put that in SA terms: the entire JSE All Share Index has a total market capitalisation of roughly R26 trillion. Nvidia alone is worth more than that.

A timeline that matters

Nvidia first crossed the $5 trillion mark on 29 October 2025, then spent six months consolidating before retaking the level on 24 April 2026. The consolidation period was driven by investor uncertainty about whether AI infrastructure spending would sustain at its breakneck pace. The April retake answered that question with a definitive yes. Nvidia's stock is up 20% in the past month alone, carried by a broader semiconductor rally that also lifted Intel, Broadcom, AMD, TSMC, and Micron.

The numbers behind the valuation are extraordinary. Nvidia's fiscal 2026 full-year revenue was $216 billion, up 65% year-on-year. Net income hit $120 billion, also up 65%. Data centre revenue, which is the core business of selling GPU clusters to hyperscalers like Microsoft, Google, Meta, Amazon, and OpenAI, grew 62% in its most recent quarter and is forecast to sustain a compound annual growth rate of 80 to 90% through 2027. Jensen Huang, Nvidia's CEO and co-founder, has projected $500 billion in GPU sales through end-2026.

Despite this, Nvidia trades at roughly 24 times forward earnings, cheaper than Apple (31x), Costco (49x), and roughly in line with the broader S&P 500 at 21.6x. That's the counterintuitive reality of Nvidia's position: it is the fastest growing mega-cap on the planet and arguably one of the cheapest on a price-to-growth basis.

What does Nvidia actually do ?

Nvidia started as a video game chip company. Its core product was the GPU (graphics processing unit) chips designed to render millions of pixels simultaneously, which turned out to be exactly what AI training requires: massively parallel computation running on enormous datasets simultaneously.

When OpenAI released ChatGPT in late 2022 and AI entered the public consciousness, Nvidia was already the dominant supplier of the hardware that made it possible. Its H100 chips and the newer H200 and Blackwell B200 architecture are the pick-and-shovel of the AI gold rush. Microsoft, Google, Meta, and Amazon are all building data centres containing hundreds of thousands of Nvidia GPUs. They cannot build AI without them.

Nvidia's software ecosystem, CUDA, is equally important. It is the programming framework that AI researchers have used to train and run models for over a decade. The network effect of CUDA, the thousands of libraries, research papers, and developer workflows built on it, represents a moat that AMD, Intel, and every new competitor has struggled to breach. Nvidia's estimated market share in high-end AI accelerators is around 84%.

Where the risks actually live

Three legitimate risks deserve investors' attention.

The first is customer competition. Nvidia's largest customers, Microsoft, Meta, Amazon, and Google, are all building their own custom AI chips. Google's Tensor Processing Units (TPUs), Amazon's Trainium, and Meta's MTIA chips are all designed to reduce dependence on Nvidia's products for specific workloads. These in-house chips won't displace Nvidia for frontier model training in the near term, but they limit the growth ceiling over time.

The second is export controls. US government restrictions on AI chip sales to China have already cost Nvidia an estimated $5.5 billion in lost revenue in April 2025. China represents a massive and underserved AI hardware market, and every quarter Nvidia cannot access it is revenue that doesn't compound.

The third is regulatory scrutiny. The European Commission has opened an investigation into Nvidia's market dominance. At 84% market share in high-end AI GPUs, the company is a natural regulatory target in any jurisdiction with active antitrust enforcement.

How SA investors can get exposure

Nvidia is listed on the NASDAQ (ticker: NVDA) and is accessible through platforms like EasyEquities at the prevailing exchange rate. At current prices above $200 per share,a single share costs over R3,300. For those who want diversified AI semiconductor exposure rather than single-stock concentration, several ETF options are worth considering. The iShares Semiconductor ETF (SOXX) and the VanEck Semiconductor ETF (SMH) both hold Nvidia as their largest position while diversifying across Broadcom, TSMC, AMD, Qualcomm, and other names in the AI chip supply chain.

On the JSE, there is no direct Nvidia proxy. The closest exposure is through Naspers (NPN) and Prosus (PRX), which own stakes in the broader global technology ecosystem through their Tencent holding. This is indirect and diluted exposure, not a semiconductor play. For more direct AI hardware exposure, the US market remains the relevant venue.

The bigger picture for SA

Nvidia's $5 trillion milestone is a barometer, not just a headline. It tells us that the world's largest investors — BlackRock, Vanguard, sovereign wealth funds, pension managers — believe the AI infrastructure buildout is not a bubble. It is a multi-decade capital cycle, similar in nature to the fibre optic buildout of the 1990s or the smartphone supply chain buildout of the 2000s. The difference is that this one is happening faster and on a larger scale than any prior technology transition.

For SA, the $46 billion AWS commitment to Cape Town data centres and Microsoft's $300 million SA cloud investment are downstream expressions of the same thesis that's driving Nvidia's stock. Every dollar of hyperscaler capex that flows into SA infrastructure is ultimately buying Nvidia chips, running in data centres that could underpin the next generation of SA financial services, healthcare AI, and precision agriculture technology.

The companies building on top of that infrastructure in SA are today's equivalent of the ISPs and web companies of 1998. Most will fail. A few will become the next Naspers. The infrastructure bet has been made. The question is who builds on it.

Investor Takeaway: Nvidia at $5 trillion trades at 24x forward earnings with 65% revenue growth, a combination that is historically unusual for companies of this size. The fundamental demand drivers remain intact. The risks are real but long-cycle: competitor chip development, export restrictions, and regulatory pressure are years-long stories, not quarterly catalysts. For SA investors, NVDA via Easy Equities USD or a broad semiconductor ETF is the most direct way to participate in the AI infrastructure supercycle from a rand-denominated base.
