Singapore tech firm Megaspeed faces US-China AI chip probe over Nvidia ties

Nvidia CEO Jensen Huang is under scrutiny over allegations that Alice Huang, a former director of Singapore tech firm Megaspeed, was a Chinese intelligence asset who had an affair with him to obtain company secrets. The claims have sparked a US-China AI chip probe. Megaspeed, which traded billions of dollars in Nvidia chips, allegedly helped Beijing skirt US export restrictions by sending advanced AI chips to China. Singapore police began investigating in February 2025, and Alice Huang was barred from the city-state in February 2026 for providing inaccurate information. The scandal has heightened national security fears amid US-China competition over AI supremacy. Nvidia controls about 90% of the market for AI training chips, and US rules since 2022 restrict their sale to China. Singapore's probe is ongoing, while Malaysia is investigating Megaspeed's subsidiary.
