US Congress widens Nvidia probe, seeks testimony from Huang and Trump officials - South China Morning Post

Congressional intervention signals a shift from regulatory oversight to geopolitical enforcement. Demanding testimony from both Nvidia's CEO and administration officials exposes the friction between commercial interests and national security protocols. This scrutiny forces Nvidia to decouple its architecture, potentially eroding the CUDA moat by accelerating the rise of alternative accelerators. Compliance costs will surge, necessitating a bifurcated supply chain strategy to mitigate export control risks. Competitors like AMD and Intel will aggressively target market segments left vulnerable by regulatory uncertainty, while domestic Chinese alternatives gain critical iteration time. Over the next 24 months, the industry's primary metric will shift from raw performance to regulatory resilience. Geopolitical risk premiums will dominate valuation models, driving a permanent fragmentation of the global semiconductor supply chain.
