June 15, 2026, (Inside AI) — ByteDance, the parent company of TikTok, is in advanced discussions with Shanghai-based chip startup Iluvatar CoreX to secure a substantial supply of AI inference chips. The talks, confirmed by two sources close to the negotiations, also include a parallel evaluation of Baidu's Kunlunxin processors, signaling a major realignment in China's AI hardware supply chain.
A Strategic Pivot in China's Chip Landscape
If finalized, Iluvatar CoreX would join Huawei and Cambricon as ByteDance's third major domestic GPU supplier. The move underscores how Chinese tech giants are rapidly diversifying away from foreign silicon, driven by both policy and pragmatism. ByteDance's appetite for inference hardware has surged alongside the explosive growth of Doubao, its flagship AI chatbot, which demands massive real-time query processing.
Domestic Chips Gain Ground
Chinese GPU and AI chipmakers captured nearly 41% of the country's AI accelerator server market last year, a sharp erosion of Nvidia's once-dominant position. While Nvidia's market share in China has effectively fallen to zero, according to CEO Jensen Huang, Tencent's Chief Strategy Officer James Mitchell noted in May that Chinese AI chips would become available in large quantities in the second half of this year.
The potential deals demonstrate that efforts by Chinese chipmakers to offer alternatives to foreign AI chips are gaining traction as Beijing promotes the use of locally developed chips to improve self-reliance amid U.S. export controls on advanced chips.
Inside the ByteDance-Iluvatar CoreX Talks
Iluvatar CoreX is expected to ship at least 50,000 chips to ByteDance this year, with the bulk earmarked for inference workloads. Inference involves answering user queries, a distinct and less compute-intensive task than AI model training. The sources cautioned that details remain fluid and subject to change.
ByteDance is also considering Baidu's Kunlunxin chips, the sources said. Tencent is already a Kunlunxin customer, according to one source. ByteDance, Iluvatar CoreX, Baidu, and Tencent did not respond to requests for comment.
A Startup's Commercial Breakthrough
For Iluvatar CoreX, a deal with ByteDance would mark a pivotal shift from government contracts to high-volume commercial deployment. The company, which listed in Hong Kong in January, reported 1 billion yuan ($148 million) in 2025 revenue, about 90% from GPU sales. Its Tiangai series targets AI training, while the Zhikai line is optimized for inference.
Huatai Securities projects Iluvatar CoreX's revenue will hit 3.04 billion yuan ($449.8 million) this year, with total shipments surging 139% to over 100,000 chips. The broker estimates Zhikai inference chips carry an average selling price of 12,000 yuan ($1,775) each. Iluvatar CoreX shares rose 12% in Hong Kong following the Reuters report.
What's Driving the Urgency
ByteDance's scramble for domestic chips reflects both the tightening U.S. export controls and the sheer scale of its AI ambitions. Doubao's rapid user growth demands a resilient, cost-effective inference infrastructure that foreign suppliers can no longer guarantee. The talks with Iluvatar CoreX and Baidu suggest ByteDance is hedging its bets, potentially blending multiple domestic sources to avoid single-vendor risk.
Yet challenges remain. Domestic chips still lag behind Nvidia's in raw performance, and scaling production to meet ByteDance's needs will test Iluvatar CoreX's manufacturing and support capabilities. The startup's heavy reliance on government deals until now raises questions about its readiness for the rigors of commercial hyperscale deployments.
The Bigger Picture
ByteDance's moves are part of a broader industry shift. As Chinese cloud providers and internet giants race to build sovereign AI stacks, domestic chipmakers are seizing a once-in-a-generation opportunity. The outcome of these talks could set a precedent for how China's tech ecosystem balances performance, supply security, and political alignment in the AI era.
