U.S. intelligence agencies suspect Megaspeed founder Alice Huang of being a Chinese spy, allegations China denies; the scandal has also been linked in reports to Nvidia chief Jensen Huang, who reportedly had an affair with her and resigned from all his Nvidia positions.

The case is unfolding alongside broader U.S. scrutiny of Chinese access to advanced computing: Treasury Secretary Scott Bessent said several departments had backed placing Singapore-based Megaspeed International on the U.S. entity list for months, but the Commerce Department controls the decision.

Chinese AI companies are seeking Nvidia-powered capacity at data centers outside China as the Commerce Department reportedly finalizes a rule to restrict remote access to advanced chips; a House-passed bill authorizing such limits awaits Senate action, and Nvidia has warned restrictions could materially affect cloud services to companies with Chinese parent firms.

The leadership change adds uncertainty around Nvidia’s strategy, customer relationships and execution, at a time when investors are questioning whether major cloud companies can earn adequate returns on AI infrastructure.

Nvidia’s board will consider internal and external candidates for the permanent CEO position, while board chair Harvey Jones said it has “full confidence” in Kress and the leadership team.

Bernstein SocGen analyst Stacy Rasgon kept a Market Perform rating and a $200 price target, saying Kress could maintain operations and near-term business appeared resilient, though uncertainty about further revelations and Huang’s replacement remained substantial.

Analysts cautioned that uncertainty about Nvidia’s direction or product roadmap could give competitors room to catch up, although chips planned for the next year or two are already designed and in production, limiting the chance of immediate disruption.

Investors have pushed rival chipmakers higher on expectations that customers may diversify suppliers: Broadcom and AMD gained 17.9% and 17.6%, respectively, while analysts also pointed to Alphabet’s tensor processing units and development partners Broadcom and MediaTek as potential beneficiaries.

William Blair analyst Sebastien Naji upgraded AMD to Outperform, citing Intel’s delayed Xeon roadmap, AMD’s valuation and the possibility that scrutiny of Nvidia and a leadership vacuum could help AMD; its data-center AI revenue was expected to exceed its server CPU business in the fourth quarter and support more than 80% revenue growth next year.

The broader selloff has been sharp: from the technology-stock peak on October 7, Nvidia fell 32%, compared with an 11% drop for the Nasdaq 100, a 30% decline for Micron and a 24% fall for the Philadelphia semiconductor index.

Nvidia’s stock had risen roughly tenfold from late 2022 through 2025 as its GPUs and CUDA software became central to generative AI, driving demand across cloud computing, software, utilities, energy and electrical equipment.

Uncertainty about data-center construction rules and electricity costs could add pressure, while a broader reassessment of AI growth would matter well beyond Nvidia because the Magnificent Seven account for nearly one-third of the S&P 500’s market value.
