Nvidia-Megaspeed case shows why Washington must help firms guard against foreign spies

Nvidia CEO Jensen Huang's departure does not resolve scrutiny over AI chip exports to China, including alleged involvement of a Chinese intelligence asset via Singapore-based Megaspeed International. The case highlights limits of relying on private firms for national security. Megaspeed, Nvidia's largest Southeast Asian buyer, imported $4.6 billion in technology from 2023 to 2025, renting chips to Chinese firms like Alibaba without violating current rules. Suspicions of physical diversion persist, though no charges have been filed. Nvidia has added voluntary tracking tools and reduced Asian buyers. Export-control enforcement has weakened since 2022, with the Trump administration reversing licensing rules and allowing H200 sales to China. The incoming Democrat-controlled Congress may revive oversight via bills like the Chip Security Act, while experts urge stronger counterintelligence coordination with private firms.
