Baidu Shares Rally as Kunlunxin Eyes $50 Billion Hong Kong IPO

Baidu Inc. (HK:9888) shares climbed sharply on Monday after reports indicated that its artificial intelligence chip subsidiary, Kunlunxin, is aiming for a valuation of approximately $50 billion through a planned initial public offering (IPO) in Hong Kong. The news fueled investor optimism, sending Baidu’s stock more than 7% higher to HK$105.80, making it one of the strongest contributors to gains in the Hang Seng Index.

According to a report from The Information, Kunlunxin is pursuing an ambitious valuation while actively encouraging investors to adopt its AI chips. The report adds to growing expectations that the company could become one of Hong Kong’s most closely watched technology listings. Although Baidu confidentially submitted its Hong Kong IPO application for Kunlunxin earlier this year, the company has yet to disclose key details, including the offering size and timeline.

Kunlunxin plays a central role in Baidu’s long-term artificial intelligence strategy. As demand for domestically developed AI semiconductors continues to accelerate across China, the chipmaker has become increasingly important to the company’s efforts to reduce reliance on foreign technology while strengthening its AI ecosystem.

Baidu already uses Kunlunxin processors to power many of its own AI models and cloud computing services. The company is also reportedly positioning the chips for broader commercial adoption by other major Chinese technology firms. Reuters previously reported that ByteDance, the parent company of TikTok, was evaluating Kunlunxin chips for AI applications, although ByteDance later denied those claims. Separate market reports have suggested that Tencent is already among Kunlunxin’s customers, highlighting the growing industry interest in the company’s semiconductor technology.

The potential IPO comes as investor enthusiasm for artificial intelligence continues to reshape Hong Kong’s capital markets. AI-focused companies have emerged as major drivers of listing activity in 2026, attracting strong institutional and retail demand. Chinese AI startups, including Zhipu and MiniMax, have recorded successful fundraising rounds and significant market attention, reflecting the broader surge in investment tied to AI innovation.

If Kunlunxin achieves its targeted valuation, the listing could rank among the largest technology IPOs in Hong Kong in recent years. The offering would further underscore the rising importance of AI chips, semiconductor innovation, and domestic technology development in China's rapidly expanding artificial intelligence sector, while reinforcing Baidu’s position as one of the country's leading AI and cloud computing companies.
