Baidu plans IPO for AI chip subsidiary amid AI demand surge

Baidu is preparing to take its AI chip unit public, and the numbers involved suggest this isn’t a modest side project. Kunlunxin, the subsidiary in question, is targeting a $50 billion valuation for its Hong Kong IPO, a figure that would represent one of the most ambitious tech listings to come out of China in recent memory.

To put that in perspective, Kunlunxin raised funds at a valuation of roughly $3 billion in 2025. Going from $3 billion to a $50 billion target in the span of a year is the kind of markup that would make even the frothiest Silicon Valley pitch deck blush.

From internal project to IPO candidate

Kunlunxin, formally known as Kunlunxin (Beijing) Technology Co., Ltd., started life around 2012 as an internal initiative inside Baidu. The original purpose was straightforward: build chips that could handle the company’s own AI workloads.

That internal tool eventually grew legs. The subsidiary expanded beyond serving its parent company and began supplying external clients, including Tencent, one of China’s largest tech conglomerates.

Baidu confidentially submitted a listing application to the Hong Kong Stock Exchange in early January 2026, structuring the deal as a spin-off. The move is designed to highlight Kunlunxin’s standalone value and attract investors who specialize in semiconductor plays rather than broad-based internet companies.

Baidu still holds approximately 58% of Kunlunxin, which means the parent company retains a controlling interest even as it invites public market investors to participate.

The subsidiary’s 2025 financial performance provides some grounding for the ambition. Kunlunxin reported revenues of RMB 3.5 billion, roughly $500 million, and achieved breakeven status.

A $50 billion question

Here’s the thing about that $50 billion target: it implies a valuation of roughly 100 times 2025 revenue.

The IPO structure itself is unusual. Investors participating in the offering may be expected to purchase Kunlunxin chip products valued at 3 to 7 times their share subscription amount. In English: if you want to buy stock, you might also need to commit to buying a substantial volume of actual chips.

Beyond Hong Kong, Kunlunxin is reportedly considering a dual listing on Shanghai’s STAR Market. China’s answer to Nasdaq, the STAR Market was specifically created to support homegrown technology companies.

China’s semiconductor independence play

Kunlunxin’s IPO sits squarely within China’s broader push toward semiconductor self-sufficiency, a strategic priority that has intensified as US export controls have restricted Chinese companies’ access to cutting-edge Western chips.

Kunlunxin’s client roster underscores this dynamic. When Tencent, a company with nearly unlimited resources, chooses to buy from a domestic supplier, it signals that Kunlunxin’s products have crossed a threshold of technical viability.

Baidu’s decision to spin off the unit rather than keep it fully embedded also reflects a calculation about capital markets. As a division within Baidu, Kunlunxin’s value was bundled with the parent company’s search engine, cloud computing, and autonomous driving businesses. The spin-off solves that problem.

What this means for investors

The chip-purchase requirement attached to share subscriptions is worth watching closely. The structure essentially converts IPO capital into pre-committed revenue, which strengthens near-term financial projections.

The risk side of the equation is equally important. A 100x revenue multiple leaves very little room for execution stumbles. If Kunlunxin’s revenue growth doesn’t accelerate dramatically from the $500 million 2025 baseline, the valuation could face serious pressure in secondary trading. Geopolitical risk also cuts both ways: while US export controls create demand for domestic alternatives, they also limit Kunlunxin’s ability to source certain manufacturing equipment and materials.

The dual-listing consideration adds another layer of complexity. Regulatory approval from both Hong Kong and Shanghai authorities is required, and navigating two sets of listing requirements simultaneously is no small administrative feat. But if successful, the dual structure would give Kunlunxin access to both international capital and the deep pool of domestic Chinese institutional money that flows through the STAR Market.
