🍠 NVIDIA, on a Day When Its Tech Announcement and Third-Party Claims Diverged - 2026.10.20

Hi, it’s Goguma. 🍠 NVIDIA news came from several directions today, so I felt like sorting it all out. The stock closed on October 19 at $217.23, up +1.45% from the previous day.

🍠 The company itself talked about technology

The clearest news is the company’s announcement. NVIDIA officially announced that it had conducted a record-setting simulation of fault-tolerant quantum computing at the Jülich Supercomputing Centre ^[1]. Quantum computing isn’t a story that translates into revenue figures right away, so I’d read this as a demonstration of technological capability. There are no figures here to use in making an investment decision, so I won’t go beyond that.

🤝 Many of the AI demand claims come from third parties

Business Post noted that the spread of agentic AI is driving higher DRAM demand for NVIDIA CPUs ^[2]. The idea is that this could create new growth opportunities for Samsung Electronics and SK hynix. However, this is the article’s claim, not a confirmed company plan. A video also covered reports that Samsung Electronics is teaming up with TSMC and applying a 3-nanometer process to NVIDIA’s ‘NVHBM’ ^[5]. Since this is based on the title and summary, the original source needs to be checked for details. It’s interesting that memory demand is being discussed along two different lines, while it remains unclear whether either will lead to a concrete supply-chain shift.

Meanwhile, a Seeking Alpha analysis article discussed the financial risks inherent in NVIDIA’s AI business expansion ^[3]. The key point is that this risk assessment comes from an analysis article. The article doesn’t establish the company’s intentions or cash flow position, so those points should be treated as claims only.

⚖️ ETF news: what a fixed weighting means

Hana Asset Management fixed NVIDIA’s weighting at 25% when it listed a U.S. AI semiconductor ETF ^[4]. The news confirms that NVIDIA is included as a major constituent of the ETF. A fixed weighting is a feature of the product’s design, not a signal about the direction of NVIDIA’s stock price. Put simply, it’s like a meal plan stuck on the fridge—the plan doesn’t guarantee the food will taste good, right?

🎯 Here are the remaining unknowns

Here’s how Goguma would sum up the four viewpoints. This time, the company announcement, third-party claims, and ETF design news belong to different layers, so I’ll leave them as they are rather than forcing them into a single narrative. The next questions are whether the technology announcement leads to real demand, whether memory demand claims are confirmed by supply-chain figures, and how the risks discussed in the analysis show up in earnings. 🤔
