ByteDance, the parent company of TikTok and Douyin, is reportedly in advanced discussions to purchase artificial intelligence chips from domestic semiconductor startup Iluvatar CoreX. The move highlights the growing urgency among Chinese technology giants to secure alternative sources of computing power as United States export controls continue to restrict access to advanced hardware.
According to a Reuters report, ByteDance is in discussions to purchase at least 50,000 of Iluvatar CoreX’s Zhikai-series inference accelerators, chips designed specifically for inference workloads rather than model training. The discussions underscore a broader shift within China’s tech ecosystem, where companies are increasingly willing to integrate domestic silicon into their data centers to mitigate supply chain risks.
The Search for Alternatives
ByteDance is one of the most aggressive investors in AI infrastructure in China. The company requires massive computational resources to train its large language models, including the Doubao foundation model, and to power the recommendation algorithms that drive its wildly successful short-video platforms.
Historically, ByteDance, like its peers Alibaba and Tencent, has relied heavily on Nvidia’s industry-leading GPUs. However, the landscape shifted dramatically following the implementation of stringent US export controls aimed at limiting China’s access to cutting-edge AI chips.
While Nvidia developed the H20 chip specifically to comply with these regulations, supply remains constrained. The H20, a scaled-down version of the H100, offers significantly lower performance, forcing Chinese companies to purchase larger quantities to achieve the same computational output. This dynamic has accelerated the search for viable domestic alternatives.
Enter Iluvatar CoreX
Shanghai-based Iluvatar CoreX (9903.HK) listed on the Hong Kong Stock Exchange in January 2026 and has since attracted significant investor attention. The company develops two main product lines: the Tiangai series for model training and the Zhikai series for inference. The Zhikai chips, priced at around 12,000 yuan (approximately $1,775) each according to Huatai Securities, are the focus of the ByteDance discussions, which target expanding the capacity of the Doubao chatbot platform.
Iluvatar CoreX reported 2025 revenue of approximately 1 billion yuan ($148 million), with around 90% derived from GPU sales. Analysts project revenue will reach 3.04 billion yuan ($450 million) in 2026, with total chip shipments rising 139% to over 100,000 units. The company’s shares rose 12% in Hong Kong trading following the Reuters report.
For Iluvatar CoreX, securing a contract with ByteDance would be a transformative milestone. It would provide crucial validation of their technology, generate significant revenue to fund further research and development, and potentially encourage other Chinese tech companies to adopt their hardware.
The Broader Implications
The potential partnership between ByteDance and Iluvatar CoreX is indicative of a larger trend: the forced decoupling of the US and Chinese technology ecosystems is accelerating the development of China’s domestic semiconductor industry.
While Chinese chipmakers still face significant hurdles, particularly in advanced manufacturing processes and software ecosystem maturity — the guaranteed demand from domestic tech giants provides a powerful catalyst for innovation. Companies like Huawei, with its Ascend series, and startups like MetaX and Moore Threads, are all vying for a share of this rapidly expanding market. As EastFrontier has previously reported, domestic chipmakers have now captured 41% of China’s AI accelerator server market, a dramatic shift from just a few years ago.
Furthermore, integrating domestic chips into large-scale commercial deployments will yield invaluable feedback, enabling Chinese semiconductor companies to iterate and improve their designs more rapidly. This iterative process is essential for closing the performance gap with established international leaders.
As the AI arms race intensifies, the ability to secure reliable, high-performance computing infrastructure will be a decisive factor. For ByteDance, diversifying its hardware supply chain is no longer just a strategic option; it is an operational necessity. The outcome of its discussions with Iluvatar CoreX will be closely watched as a barometer for the progress and viability of China’s domestic AI chip industry.
The Software Ecosystem Challenge
One of the most significant obstacles facing domestic AI chip makers is not hardware performance, but software compatibility. The global AI development ecosystem has been built almost entirely on Nvidia’s CUDA platform, a proprietary software layer that allows developers to write programs that run efficiently on Nvidia GPUs.
For Chinese chipmakers like Iluvatar CoreX to succeed, they must offer not just competitive hardware, but also a compelling software stack that allows developers to migrate their existing workloads with minimal friction. This is an enormous undertaking, as the CUDA ecosystem represents decades of accumulated development and optimization.
Companies like Huawei have made significant investments in their own software frameworks, such as MindSpore and the CANN (Compute Architecture for Neural Networks) toolkit, to address this challenge. Iluvatar CoreX will need to demonstrate a similar commitment to building a robust, developer-friendly software ecosystem if it hopes to achieve widespread adoption beyond a captive domestic market.
A Pivotal Moment for China’s Chip Industry
The potential ByteDance-Iluvatar CoreX deal arrives at a pivotal moment for China’s semiconductor ambitions. The country has invested hundreds of billions of yuan in domestic chip development, driven by the recognition that reliance on foreign suppliers represents a critical strategic vulnerability.
While much of this investment has been directed toward advanced logic chips and memory, the AI accelerator market represents a particularly important battleground. The ability to design and manufacture competitive AI chips domestically would significantly reduce China’s dependence on foreign technology and provide a stable foundation for its long-term AI ambitions.
If ByteDance proceeds with the purchase, it would represent a significant vote of confidence in the domestic chip industry — and a powerful signal to other Chinese tech giants that the time has come to seriously integrate homegrown silicon into their infrastructure.
