Key Takeaways
- KeyBanc’s John Vinh projects Nvidia could reduce 2026 Rubin GPU output to 1.5 million units instead of the targeted 2 million.
- High-bandwidth memory supply constraints from SK Hynix and Micron Technology are driving the potential production shortfall.
- KeyBanc maintains its Overweight rating with a $275 price target on NVDA despite supply concerns.
- Jensen Huang, Nvidia’s CEO, confirmed Vera Rubin AI servers have entered “full production” with anticipated sales starting in the second half of 2026.
- Nvidia commands approximately 90% of AI accelerator spending and around 85% of the total AI chip market.
A recent research note from KeyBanc suggests that Nvidia might be compelled to reduce its manufacturing targets for the upcoming Rubin graphics processing units. The financial institution estimates that production volumes could reach approximately 1.5 million units in the current year, representing a decline from the initially projected 2 million units.
The root cause? Supply constraints in high-bandwidth memory. Reports indicate that memory suppliers SK Hynix and Micron Technology have encountered challenges in providing sufficient quantities of the advanced memory components essential for Rubin GPU manufacturing, resulting in the anticipated production deficit.
John Vinh, the analyst behind the report, raised the supply concern but maintained a measured outlook. His Overweight recommendation on the stock remains unchanged, with his $275 price objective significantly exceeding current trading levels.
The Rubin GPU serves as the foundation for Nvidia’s forthcoming Vera Rubin AI server systems, which CEO Jensen Huang confirmed have entered “full production” status. The company expects to begin shipping these systems during the latter half of this year.
These servers represent a substantial performance leap. Vera Rubin is anticipated to deliver 3.3 times the computational speed of Blackwell Ultra — Nvidia’s current flagship offering. The architecture combines Rubin GPUs with Vera central processing units.
Nvidia had not provided a response to inquiries by press time.
Market Position Remains Unchallenged
Despite the manufacturing challenge, Nvidia’s dominance in artificial intelligence semiconductor markets continues unabated. The corporation accounts for approximately 90% of AI accelerator expenditures and maintains roughly 85% share of the comprehensive AI chip sector.
Major technology companies are forecasted to allocate between $600 billion and $700 billion toward AI data center infrastructure in 2026 alone — an investment wave that positions Nvidia ahead of all competing chipmakers.
During its latest quarterly report, Nvidia delivered revenue expansion of 75% compared to the prior year period. Its first-quarter outlook exceeded Wall Street projections by $5 billion, signaling projected growth near 77%.
Hedge fund manager Ken Griffin maintains roughly $4 billion in Nvidia shares, representing his largest portfolio holding based on recent regulatory disclosures.
Expanding Beyond Hardware
Aside from its chip business, Nvidia has been systematically developing its software operations. The company’s AI Enterprise platform is projected to achieve margins exceeding 80% and could generate $10 billion in annual revenue by 2027.
Physical AI applications — including robotics, self-driving vehicles, and humanoid manufacturing systems — constitute another hardware opportunity that market observers believe remains in its nascent stages.
Monday’s premarket activity aligned closely with broader market trends. S&P 500 futures advanced 0.1%, while Dow Jones futures showed minimal movement.
Broadcom (AVGO) climbed 0.5% and Advanced Micro Devices (AMD) gained 0.7% during premarket hours.
