Baidu chip unit Kunlunxin files for Shanghai IPO alongside Hong Kong plan

Baidu’s AI chip arm Kunlunxin has filed paperwork to list on Shanghai’s STAR Market in addition to a separate Hong Kong IPO already in train, in a move that would put one of China’s home-grown semiconductor champions in front of two pools of investors at once.

China International Capital Corp (CICC) submitted a tutoring agreement for Kunlunxin to the Chinese Securities Regulatory Commission, according to a regulatory filing dated April 29 and reported Friday by The Business Times. Tutoring is the pre-IPO compliance and disclosure programme that Chinese issuers must complete before submitting a domestic listing application.

Baidu’s Hong Kong-listed shares closed up 5.75 per cent at HK$145.20 on Friday, having traded as high as HK$145.90 earlier in the day. The stock was up as much as 4.1 per cent at one point.

A second route to capital

Kunlunxin filed a confidential application for a Hong Kong listing in January, Baidu said at the time. Jefferies analysts led by Thomas Chong said in a note Friday that pursuing the parallel Shanghai listing was a step forward in the spin-off plan, because an onshore listing makes it easier for Chinese AI model developers and chipmakers to reach domestic investors. The team still expects the Hong Kong debut to land in the third quarter.

Baidu owns 58 per cent of Kunlunxin. Bloomberg pegged the unit’s valuation at about US$3 billion in December following a funding round, equivalent to roughly 21 billion yuan. The company has not disclosed the size or pricing of either listing.

Baidu CEO Robin Li has framed AI as the “new core of Baidu,” with finance chief Henry He saying earlier in 2026 that the company plans to invest more than 100 billion yuan in AI over three years. Kunlunxin started as Baidu’s in-house chip operation before being spun out as an independent entity, and most of its silicon has historically gone into Baidu’s own products. Outside sales have picked up in recent quarters.

The market backdrop

Shanghai’s tech-heavy STAR 50 Index has gained more than 20 per cent in 2026 and reached an all-time high on Thursday, a backdrop that suits domestic chip listings. Recent debuts including Shanghai Biren Technology, Metax Integrated Circuits Shanghai and Moore Threads Technology have all surged from their offering prices in the past year.

The momentum tracks a Beijing policy push to grow Chinese semiconductor champions while the United States restricts the most advanced chips made by Nvidia and others. Domestic chipmakers including Huawei Technologies and Cambricon Technologies have reported sharp revenue jumps as Chinese AI model developers including DeepSeek and ByteDance continue to release new models that need large fleets of inference accelerators.

What it means for Baidu

The dual-listing structure gives Kunlunxin access to mainland Chinese institutional investors via the STAR Market and to international capital via Hong Kong. It also lets Baidu separate the chip business’s market value from its slower-growing search and advertising operation.

Baidu’s traditional ad business has been under pressure for several quarters. The company posted a 4 per cent drop in fourth-quarter revenue in February as weak ad sales offset gains from its cloud unit. Baidu reports first-quarter results before the US open on May 18 and follows with a management call at 8 p.m. Beijing time.

The spin-off would still leave Kunlunxin a Baidu subsidiary, the parent said in earlier disclosures, with consolidated financials retained at the group level.

Competition closing in

Baidu’s main domestic rivals are not standing still. Alibaba is reportedly preparing a separate listing for its chipmaking arm, T-Head, which has spent the past year producing a server CPU line and AI accelerators. Tencent has not signalled a similar carve-out for its in-house silicon work. Several pure-play Chinese chip startups including Iluvatar CoreX and Enflame Technology are also lining up domestic listings.

For investors, the question is whether Kunlunxin can capture enough of the inference workload that Chinese AI model developers will run over the next two to three years. Inference, the processing needed to serve already-trained models to end users, scales with usage and tends to favour cheaper, more power-efficient chips over the leading-edge training silicon that Nvidia dominates.

Risks to the deal

Baidu has flagged several execution risks. The company said the size, structure and timing of the spin-off remain subject to approvals from the Hong Kong Stock Exchange and Chinese regulators, and that the deal could be delayed or cancelled. The Shanghai listing requires a separate approval track that typically runs six to nine months from tutoring filing to first trading day.

A market downturn, a regulatory tightening of cross-border listings, or a softening in Chinese AI capex would all weigh on pricing. The Q1 earnings print on May 18 is the next catalyst either way.
