ByteDance, the Beijing-based owner of TikTok, is actively courting a group of smaller domestic semiconductor suppliers to power its cloud infrastructure, as tightening US export controls continue to restrict access to Nvidia hardware. The move signals a structural shift in how China's largest consumer-tech companies are rebuilding their AI supply chains from the ground up.

The tier-two chipmakers in the frame

According to sources and analysts, ByteDance is evaluating so-called tier-two chipmakers — smaller domestic rivals to Huawei Technologies and Cambricon Technologies — for cloud workloads. Analysts identified this group as including Biren Technology, MetaX Integrated Circuits, Iluvatar CoreX, Moore Threads Technology, and Enflame Technology, all of which have been competing to land orders from one of China's largest cloud service providers.

Iluvatar deal already done

In a notable early move, ByteDance quietly purchased tens of thousands of AI processors from Shanghai-based Iluvatar CoreX at a favourable price, according to two sources familiar with the matter. The company is also reportedly in active talks with several other domestic chipmakers for potential follow-on orders. ByteDance and Iluvatar did not immediately respond to requests for comment.

Why it matters

The scale of ByteDance's spending gives it unusual leverage to accelerate the maturation of China's domestic GPU ecosystem. When a hyperscaler-level buyer commits to tens of thousands of units, it provides the revenue certainty that smaller fabs and chip designers need to invest in next-generation architectures. Beijing's policy push for home-grown semiconductors has created both the regulatory pressure and the demand signal that tier-two players have long needed.

The competitive backdrop

Huawei Technologies and Cambricon Technologies remain the dominant domestic AI chip suppliers, but their capacity is constrained and demand from Chinese cloud providers far outstrips supply. Tier-two vendors are positioning themselves as overflow suppliers initially, with ambitions to close the performance gap over successive chip generations. The race is complicated by ongoing US sanctions that limit access to advanced chip-manufacturing equipment, keeping yields and clock speeds below what Nvidia's H100-class hardware delivers.

What's next

Whether Biren Technology, MetaX Integrated Circuits, Moore Threads Technology, and Enflame Technology can convert evaluation orders into large-scale contracts will depend on proving reliability at hyperscaler volumes — a bar none of them has yet publicly cleared. Analysts will be watching ByteDance's next infrastructure capex disclosures for evidence that domestic chip spending is rising as a share of total procurement, a metric that would confirm the structural nature of the shift rather than a one-off hedge.
