Musk's Nvidia Endorsement: AMD Investors Take Note

Sep 1, 2026

💡 Key Takeaway

Elon Musk's exclusive endorsement of Nvidia, combined with superior growth and lower valuation, makes NVDA a stronger pick than AMD for AI exposure.

Musk's Endorsement: Nvidia's Rubin Architecture Wins

During SpaceX's Q2 conference call, Elon Musk revealed that his companies, including SpaceX and xAI, will exclusively use Nvidia's computing units going forward. He praised Nvidia's upcoming Vera Rubin architecture as the best AI computer, citing its efficiency and performance.

This endorsement is significant because Musk is a highly influential tech leader, and his companies are major consumers of AI computing power. Tesla also relies on Nvidia for training its self-driving AI models, though the exclusive commitment was specifically for SpaceX and xAI.

Nvidia's next-generation Rubin architecture promises a tenfold reduction in inference token cost and a fourfold decrease in GPUs needed for training, making it more efficient and cost-effective. These improvements could drive further adoption and revenue growth for Nvidia.

In contrast, AMD, while a strong competitor, did not receive such a high-profile endorsement. The news highlights Nvidia's technological edge and strategic partnerships, which are crucial in the competitive AI chip market.

This development comes as both companies report strong earnings, but Nvidia's growth metrics outpace AMD's, reinforcing its leadership position.

Why This Matters for Investors

Musk's endorsement is a powerful signal that Nvidia's technology is preferred by one of the most demanding AI users. This could translate into sustained demand for Nvidia's chips, as other companies may follow suit to stay competitive.

Nvidia's growth is already impressive: total revenue surged 106% year-over-year, and data center revenue grew 117%. In comparison, AMD grew 50% overall and 107% in data centers. Nvidia's faster growth, combined with a lower valuation (trading at roughly one-third of AMD's price-to-earnings ratio), makes it an attractive investment.

The Rubin architecture's efficiency improvements could lower costs for AI companies, potentially expanding the market and benefiting Nvidia. However, AMD is not far behind and could still gain market share with its own innovations.

For investors, this news reinforces Nvidia's competitive moat and growth prospects. It also raises questions about AMD's premium valuation, which may be hard to justify given its slower growth and lack of similar endorsements.

Ultimately, the choice between NVDA and AMD hinges on growth, valuation, and technological leadership. Current data favors Nvidia, making it a compelling pick for AI-focused investors.

Bobby Insight

Nvidia is the better AI stock pick over AMD due to faster growth, cheaper valuation, and Musk's endorsement.

Nvidia's revenue growth is double AMD's, yet it trades at a lower P/E. The Rubin architecture's efficiency gains could drive further adoption. While AMD has potential, Nvidia's current advantages are too significant to ignore.

What This Means for Me
