Stock Spotlight: NVDA — The AI Chip King at the Centre of the US-China Tech War

There's a moment from last week that will likely appear in future business school case studies: Jensen Huang, CEO of Nvidia (NVDA), was picked up by Donald Trump on Air Force One in Alaska, mid-route to Beijing.

The most powerful politician on earth. The most consequential tech CEO of this generation. Flying together to negotiate semiconductor access with China. If you needed a single image to capture the geopolitical centrality of AI chips in 2026, that's it.

NVDA hit a record high this week. Here's why — and whether the story still has legs from here.

What Nvidia Actually Does

Nvidia started as a gaming graphics card company. Jensen Huang co-founded it in 1993 out of a Denny's in East San Jose — a founding origin story the company has leaned into ever since. Today, it's the dominant global designer of graphics processing units (GPUs) that power artificial intelligence infrastructure at scale.

The GPU's parallel processing architecture — originally built for rendering 3D game environments — turned out to be exactly what machine learning workloads needed. Training a large language model requires running billions of matrix multiplication operations simultaneously. CPUs do this sequentially. GPUs do it in parallel. That structural advantage made Nvidia the default infrastructure layer for AI — first in research labs, then in hyperscale cloud data centres, and now in every serious AI deployment globally.

As of May 2026, Nvidia's market capitalisation has fluctuated around the $5.4–5.5 trillion mark, making it the largest publicly traded company in history. Its H100 chip became the industry standard for AI training. The successor — the H200 — is faster, more energy-efficient, and substantially more powerful. It's also the chip at the centre of the China story.

The H200 Deal: What's Happened and What Hasn't

In January and February 2026, the US government granted export licence approvals for H200 chip sales to approximately ten Chinese companies. ByteDance, Alibaba, Tencent, and DeepSeek were among the first recipients. Jensen Huang confirmed the licences in March 2026.

Here's the critical detail: as of mid-May 2026, not a single H200 chip has shipped to China.

The licences exist. The commercial relationships are ready. The hold is diplomatic — a lever that Washington has consciously chosen not to pull yet, either as a bargaining chip in broader trade negotiations or pending clarity on enforcement mechanisms around end-use. The Hormuz situation and the broader US-China diplomatic engagement have complicated the timeline.

This is what Jensen Huang's presence in Beijing represents. He wasn't there for tourism. Nvidia cannot ship chips to China without US government clearance, and the most direct way to accelerate that clearance is to be in the room where the decisions are made. That Huang was on Air Force One — not just in Beijing, but on the flight there — signals the Trump administration's view that the H200 shipment question is tied directly to the diplomatic track.

For the market, this is a clear near-term catalyst. If H200 shipments unlock to even a fraction of the approved buyers, Nvidia captures incremental revenue from the world's second-largest economy in a sector — AI infrastructure — that is growing explosively. The China re-entry isn't Nvidia's core thesis. It's upside on top of an already compounding base.

Business Fundamentals: Why the Base Case Is Already Strong

Even without China, Nvidia's fundamentals are compelling.

Data Centre: This is the core engine. AWS, Azure, Google Cloud, and Meta are all buying Nvidia chips at scale to power AI services — from LLMs to inference compute to model training pipelines. Data centre revenue has grown from a rounding error to the dominant segment of Nvidia's business over five years.

Gaming: The original business hasn't gone away. GPU demand for gaming remains strong, and Nvidia maintains a premium position in consumer graphics with its GeForce line.

Automotive: An emerging growth segment. Nvidia's DRIVE platform is embedded in autonomous vehicle development programs across multiple manufacturers. This is early-stage revenue but a long-term diversification lever.

Enterprise AI: As companies move from AI experimentation to production deployment, compute demand scales. Every enterprise that trains a model, runs inference at scale, or builds AI-native products is a potential Nvidia customer.

The through-line: the AI infrastructure buildout is not slowing. It's accelerating. And Nvidia sits at the single point of constraint in that supply chain.

Valuation Snapshot

As at date of this article’s publication, NVDA is trading near record highs at approximately $225—235 per share. Market capitalisation is approximately $5.46 trillion. Forward price-to-earnings (P/E) ratios in the 35—45x range have been cited by analysts in optimistic scenarios — elevated, but not without precedent for a company growing revenue at the pace Nvidia has delivered.

The valuation premium reflects the market's conviction that Nvidia's earnings trajectory justifies the multiple. That conviction is tested every quarter. Nvidia has consistently beaten expectations — but at these levels, the bar is high.

How to Buy NVDA in Australia

Australian retail investors have several straightforward options:

CommSec International — ANZ-backed and well-established. Higher brokerage than specialists (~$19.95 USD per trade) but trusted and integrated with Commonwealth Bank accounts.

Stake — Popular with Australian US equity investors. Lower brokerage (USD $3 per trade on the standard plan), clean interface, good for building positions gradually.

Superhero — Competitive pricing (USD $2 per trade for US equities) and a simple interface. Growing user base among younger Aussie investors.

All three platforms give you direct ownership of NVDA shares — not a CFD, not a derivative. You're buying shares on the NYSE, settled in USD. Currency conversion applies at the point of purchase and sale. Keep records for EOFY.

The Risks — And They're Real

Export control rollback. The H200 approvals were made under the current administration. They can be reversed. A geopolitical deterioration — particularly around Taiwan — could see chip export controls tighten rapidly. Nvidia has navigated export restrictions before; it doesn't make them painless.

Huawei Ascend. China is not sitting still. Huawei's Ascend AI chip is improving. Chinese cloud providers are under pressure to source domestically. Nvidia's China window may be more time-limited than the market assumes — and if domestic alternatives reach competitive performance, the H200 opportunity shrinks.

Valuation premium. At $5.46 trillion market cap, a lot of good news is priced in. If revenue growth decelerates — even slightly below expectation — the stock will reprice sharply. This is a high-multiple, high-expectation company. It rewards holders over long periods but punishes the impatient.

Geopolitical binary. The H200 shipment approval is a binary event. If it doesn't happen — or is revoked — the near-term catalyst disappears and the stock will react accordingly. This is priced in as a high-probability event. If that probability shifts, so does the price.

The Bottom Line

Nvidia is the most direct proxy for the AI infrastructure supercycle. If you believe that AI infrastructure spending is going to compound over the next decade — and the evidence strongly suggests it will — NVDA is the foundational holding that captures that thesis most cleanly.

The China story is a genuine near-term catalyst. Jensen Huang on Air Force One is not a routine diplomatic gesture — it's the market's clearest signal that the H200 shipment window is actively being negotiated at the highest level. If it unlocks, NVDA gets a material revenue injection on top of an already strong base. If it doesn't, the core data centre growth thesis continues independently.

At current valuations, NVDA isn't a value stock — it never was. It's a conviction play on the direction of the global economy. The question isn't whether AI infrastructure will be built. It will. The question is whether Nvidia remains the dominant chip at the centre of it.

The evidence right now says yes.
