Shares of NVIDIA Corporation (NASDAQ:NVDA) rose a mere 0.8% on Monday, a muted move that stood in contrast to a 3.2% surge in the Philadelphia Semiconductor Index and strong gains from peers Advanced Micro Devices Inc (NASDAQ:AMD) and Broadcom Inc (NASDAQ:AVGO), which climbed 7.7% and 4.4% respectively. The stock’s relative weakness followed publication of a boutique supply-chain research note that alleged material delays and design changes to Nvidia’s forthcoming server hardware.
Supply-chain specialist SemiAnalysis said in a weekend report that Nvidia’s next-generation Kyber NVL144 rack architecture has been pushed out to 2028 because of manufacturing difficulties with its printed circuit board midplane. The research note also stated that an alternate back-to-back rack design was cancelled after significant operational resistance from hyperscale cloud customers, and that a planned four-die configuration on the Rubin Ultra platform was removed in a scaled-back design.
An Nvidia spokesperson countered the allegations in a brief emailed statement, saying: "Our roadmap is intact." The company did not provide additional details in that reply.
The assertions contained in the research note had immediate market consequences beyond Nvidia’s stock. Asian suppliers exposed in the report experienced sharp overnight selloffs as investors collected gains after significant year-to-date advances. Japan’s Ibiden Co., which the report noted counts Nvidia as a major client, fell 8.4% by the close. In Hong Kong, Kingboard Laminates Holdings Ltd. slumped 12.6%, and South Korea’s Samsung Electro-Mechanics Co. slid 8.1%.
Analysts quoted in reporting on the episode warned the alleged technical setbacks could constrain how quickly Nvidia can scale future hardware, potentially widening opportunities for alternative AI platforms. The report specifically cited competitive pressure from AMD’s MI500X and Broadcom-backed custom TPUs as beneficiaries should Nvidia encounter protracted scale-up issues.
Mizuho analyst Jordan Klein pushed back on the delay narrative in his daily "Tech Bytes" note, labeling the product delay accounts as "more noise." Klein advised investors not to be alarmed or to sell the stock on those reports. He noted recent robust results from Hon Hai Precision Industry Co Ltd (TW:2317), one of Nvidia’s larger suppliers, and highlighted Hon Hai management’s forecast of continued acceleration in AI demand as supportive ahead of Nvidia’s planned Vera Rubin rack launch.
The subdued performance in Nvidia’s session leaves the company trading in a range as market participants wrestle with an increasingly nervous AI hardware thematic. Volatile headlines around other major technology players have stoked swings in investor sentiment, and the recent episode underlines how sensitive the market remains to supply-chain and product-roadmap news.
Investors reacted to an unverified account of manufacturing friction with notable caution, reflecting a fragile consensus in an industry whose valuation multiples are viewed by many as sensitive to execution risk. Even though Nvidia issued a denial, the market’s response demonstrates that any hint of a roadmap disruption is capable of prompting traders to reassess near-term expectations for product availability and scale.
Contextual notes
- The claims in the SemiAnalysis report include a delay of the Kyber NVL144 rack to 2028 due to PCB midplane manufacturing problems, cancellation of a back-to-back rack design after hyperscaler pushback, and a downsizing of Rubin Ultra that removed a four-die configuration.
- Nvidia publicly stated its roadmap remains intact in response to the research note.
- Supplier equities across Japan, Hong Kong, and South Korea sold off sharply after the report, reflecting investor sensitivity to potential component-level disruptions.
