Nvidia Corporation (NASDAQ:NVDA) shares rose modestly by 0.8% on Monday, markedly underperforming the broader semiconductor rally that saw the Philadelphia Semiconductor Index climb 3.2%. In contrast, peer chipmakers Advanced Micro Devices Inc (NASDAQ:AMD) surged 7.7% and Broadcom Inc (NASDAQ:AVGO) jumped 4.4%.
The muted reaction followed a weekend research note from supply‑chain analyst firm SemiAnalysis, which claimed that Nvidia’s forthcoming Kyber NVL144 rack architecture would be postponed to 2028 because of manufacturing difficulties with its printed‑circuit‑board (PCB) midplane. The report also asserted that Nvidia had scrapped an alternative back‑to‑back rack design after receiving strong operational pushback from hyperscale cloud customers, and that a four‑die configuration of the upcoming Rubin Ultra platform had been eliminated.
Nvidia promptly denied the allegations in a brief emailed statement to Investing.com, asserting that “Our roadmap is intact.” Despite the company’s denial, the news sparked a sharp sell‑off among Asian PCB suppliers that count Nvidia as a major client. Japan’s Ibiden Co. 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%.
Analysts cited by Bloomberg warned that the rumored technical setbacks could materially constrain Nvidia’s ability to scale up future hardware production, potentially opening a competitive window for rival AI platforms such as AMD’s MI500X and Broadcom‑backed custom tensor processing units (TPUs). The episode underscores the heightened sensitivity of AI‑focused equities to any hint of product‑roadmap disruption, especially after recent market turbulence triggered by mixed headlines on Meta Platforms’ AI spending ambitions.
Overall, the episode left the world’s most valuable public company trading within a narrow range as investors remain cautious amid an increasingly jittery AI market environment.
