Full story

Chinese AI startup DeepSeek is reportedly working on a custom AI chip to bypass US export controls, a move that could reshape the global semiconductor landscape. The effort aims to reduce reliance on restricted US-made components, particularly GPUs from Nvidia, which have been subject to tightening export restrictions. Analysts suggest this strategy could help DeepSeek maintain access to advanced AI hardware despite geopolitical barriers.

The news has already sent ripples through the market, with Nvidia’s stock sliding as investors weigh the potential long-term impact on demand for its high-end AI chips. The development underscores the growing urgency among Chinese firms to secure alternative supply chains amid escalating US-China tech tensions. If successful, DeepSeek’s custom chip could set a precedent for other companies seeking to circumvent sanctions, though significant technical and regulatory hurdles remain.
