Baidu (BIDU) Stock; Dips Slightly Amid Kunlunxin GPU Expansion

TLDRs;

• Baidu sees slight stock decline despite leading China’s GPU cloud market.
• Kunlunxin GPU shipments grow, reinforcing Baidu’s AI platform capabilities.
• Frost & Sullivan highlights limited large-scale deployment among domestic GPU vendors.
• Baidu confidentially files Kunlunxin IPO amid China’s semiconductor self-sufficiency push.

Baidu (BIDU) stock edged slightly lower as investors weighed the company’s ongoing GPU expansion against broader market pressures. Despite the modest dip, Baidu remains a dominant force in China’s GPU cloud market, holding a 40.4% share in the first half of 2025, according to a Frost & Sullivan report. Huawei follows with a 30.1% share, together controlling over 70% of the market.

The company’s Kunlunxin GPUs, integrated into Baidu’s Baige AI platform, continue to drive its technology leadership. In 2024, nearly 70,000 Kunlunxin units were shipped, according to IDC data, reflecting Baidu’s ongoing push to strengthen domestic AI infrastructure and reduce reliance on foreign technology.

Vertical Integration Shapes Market Dominance

Industry analysts emphasize that vertical integration, covering chip design, data center deployment, and cloud services, remains a key driver of market share. Only firms managing the full chip-to-cloud chain are counted in market statistics, which favors well-resourced companies like Baidu and Huawei.

“Baidu’s strategy of combining hardware, software, and cloud services under one ecosystem gives it a competitive edge,” said Frost & Sullivan. While other domestic vendors continue to face challenges in scaling deployments and integrating systems, Baidu’s full-stack approach ensures it maintains a commanding presence.

Domestic GPUs Move From Backup to Core

China’s drive for semiconductor self-sufficiency has elevated domestic GPUs from “strategic backups” to essential pillars of AI computing. Over the next three to five years, local chips, including Baidu’s Kunlunxin and Huawei’s Ascend series, are expected to form the backbone of AI infrastructure.

Transitioning from Nvidia’s CUDA-based workloads remains a challenge. Transcompilation tools that translate CUDA code to local GPUs are still imperfect, and performance can vary across frameworks. Cloud providers and AI platforms are exploring services to help migrate workloads, including machine learning operations (MLOps) tools and performance optimization layers, presenting potential new revenue streams.

IPO Plans Highlight Long-Term Strategy

Baidu has confidentially filed for a Hong Kong IPO for Kunlunxin, signaling ambitions to expand production and software development. This step comes as other domestic GPU makers, including Moore Threads and Biren Technology, also explore public listings.

Beijing’s policies promoting semiconductor self-sufficiency are expected to benefit firms with vertically integrated AI ecosystems.

Investor Outlook

While Baidu’s stock experienced a slight pullback, the company’s leadership in GPU cloud technology remains strong. Analysts note that the Kunlunxin expansion, combined with vertical integration and IPO plans, positions Baidu for long-term growth in China’s AI infrastructure market.

Investors will be watching both the adoption of domestic GPUs and the performance of Baidu’s stock in a competitive landscape shaped by hardware innovation and regulatory support.
