Market Reaction
On 6 July 2026, Nvidia Corporation (NASDAQ:NVDA) shares edged up 0.8% in a Monday session, markedly underperforming the 3.2% rise in the Philadelphia Semiconductor Index and trailing peer gains of Advanced Micro Devices Inc (AMD) at +7.7% and Broadcom Inc (AVGO) at +4.4%.
SemiAnalysis Report Claims
Research firm SemiAnalysis released a weekend report alleging that Nvidia’s upcoming Kyber NVL144 rack architecture will be postponed to 2028 because of manufacturing challenges with its printed‑circuit‑board (PCB) midplane. The report further claimed that Nvidia cancelled an alternative back‑to‑back rack design after receiving strong push‑back from hyperscale cloud customers and that a four‑die configuration slated for the Rubin Ultra platform had been removed.
Nvidia Response
Nvidia’s spokesperson responded by email to Investing.com, stating succinctly that “Our roadmap is intact,” thereby rejecting the delay and design‑cancellation allegations.
Supplier Stock Impact
The unverified technical setbacks sparked a sharp sell‑off among Asian semiconductor‑related suppliers. Japan’s Ibiden Co., a major PCB supplier to Nvidia, fell 8.4% by market close; Hong Kong‑listed Kingboard Laminates Holdings Ltd. dropped 12.6%; and South Korea’s Samsung Electro‑Mechanics Co. slid 8.1%.
Analyst Commentary
Bloomberg‑cited analysts warned that the rumored setbacks could limit the scale‑up capacity of Nvidia’s future hardware, potentially widening the competitive window for AMD’s MI500X and Broadcom‑backed custom TPUs. Contrasting this view, Mizuho analyst Jordan Klein, in his daily “Tech Bytes” note, dismissed the delay stories as “more noise,” stating he would not be worried about Nvidia or consider selling the stock. Klein also highlighted strong earnings from Hon Hai Precision Industry Co Ltd (TW:2317), one of Nvidia’s largest suppliers, noting that Hon Hai’s management forecast a continued acceleration in AI demand—a “very good sign” for Nvidia’s upcoming Vera Rubin rack launch.
Broader AI Market Context
The muted session leaves the world’s most valuable public company range‑bound as investors grapple with heightened anxiety in the AI trade. Recent volatile headlines about Meta Platforms’ AI spending ambitions had already sent tech stocks on a whipsaw ride, underscoring the fragile consensus among AI investors after a multi‑year historic run‑up.
