The Unlikely Chip Startups ByteDance Is Betting On to Defy US Sanctions

ByteDance, the parent company of TikTok and Douyin, is significantly increasing its investment in AI infrastructure, a move that directly boosts China's domestic AI chip industry. The company plans to integrate more Chinese-made chipsets into its cloud AI workloads, partnering with second-tier AI semiconductor startups such as Ilubata CoreX, Virun Technology, MetaX, Moores Thread Technology, and EnFlame Technology. This strategy aims to reduce reliance on foreign chips, particularly Nvidia's, which are now subject to strict US export controls targeting advanced AI hardware.

By shifting to domestic suppliers, ByteDance not only secures its own AI compute capacity but also provides critical revenue and validation for smaller Chinese chip firms still scaling their technologies. This collaboration could accelerate the maturation of China's indigenous AI chip ecosystem, helping it compete with global leaders. The move reflects a broader trend: major Chinese tech companies are increasingly pivoting to homegrown semiconductors to circumvent US sanctions and strengthen national tech resilience. For ByteDance, this ensures stable access to AI accelerators needed for training large models and powering recommendation algorithms—core to its business.
