Kunlunxin
State of play as of
Baidu’s in-house AI chip unit, spun out toward a dual listing, and the clearest case of how far a reported valuation can travel without a filing behind it.
Kunlunxin is Baidu’s answer to the question every Chinese AI company now has to answer: what happens when you cannot buy Nvidia. It began in 2012 as an internal chip team, and its third-generation P800 now runs the majority of Baidu’s own inference. It is also the best current example of how numbers behave around a Chinese chip listing. The figures attached to this company moved from a priced round at about $2.97 billion to a reported target near $50 billion inside seven months, each level widely quoted, none of it filed publicly. This page keeps those figures with the dates and outlets attached, and distinguishes the one that was paid from the ones that were sought, because the sequence is the story. We track what Kunlunxin ships, what it earns, and what has actually been filed, with dates and sources.

- Founded
- 2012, as Baidu’s internal AI chip team. Now independently operated, with Baidu retaining a controlling stake.CNBC, company materials
- Listing status
- Filed, not listed. Kunlunxin filed a confidential Hong Kong main-board application as a carve-out from Baidu on 2 January 2026, and began STAR Market listing guidance, the mainland pre-filing stage, on 7 May 2026. A confidential filing puts no prospectus or terms on the public record.Bloomberg, CNBC, EE Times China via TrendForce
- Valuation: priced against sought
- One priced round and two targets, and the difference matters. Reuters reported on 4 December 2025 that a completed funding round valued Kunlunxin at 21 billion yuan, about $2.97 billion; some coverage rendered that same figure as HK$23.11 billion. SCMP then reported on 8 May 2026 that it was seeking at least 100 billion yuan, about $14.69 billion, and The Information reported a target near $50 billion on 29 June 2026. Only the first was paid; the other two are pre-filing targets, and none is a filed figure.Reuters; SCMP; The Information

- Deployment
- Baidu said in April 2025 it had brought up a 30,000-card P800 cluster, which it described as able to train models with hundreds of billions of parameters. That is a company claim.Baidu, Reuters

The state of play
The Information reported that Kunlunxin is targeting a Hong Kong listing at a valuation near $50 billion, citing two sources, and that investors had been asked to buy chips worth three to seven times the value of their intended subscription. Baidu’s Hong Kong shares rose more than 7 percent, and the target was larger than Baidu’s entire market value at the time. The figure is the last in a sequence that is easy to misread as one number moving. Reuters reported in December 2025 that a completed round had valued Kunlunxin at 21 billion yuan, about $2.97 billion, and SCMP reported on 8 May 2026 that it was seeking at least 100 billion yuan, about $14.69 billion. Only the first was a price anyone paid; the rest are targets, and none is filed, because the Hong Kong application is confidential. The reported subscription condition is the detail with the most consequence, because tying share allocation to chip purchases makes demand for the stock and demand for the product difficult to tell apart, and the revenue that results difficult to read.
Kunlunxin began the STAR Market listing guidance process on 7 May 2026, the pre-filing tutoring stage a mainland listing requires, putting it on a dual track alongside the confidential Hong Kong application it filed on 2 January. Running both at once has become the default for Chinese chip companies with the standing to try it, because the two venues price the same asset differently and neither is guaranteed to open. No STAR Market application has been filed. Which track completes first, and whether the other quietly lapses, will say more about where domestic capital wants this company listed than any of the reported valuations.
Kunlunxin filed a confidential main-board application with the Hong Kong exchange as a carve-out listing from Baidu. Founded in 2012 as Baidu’s internal chip team, it is now independently operated with Baidu retaining control, and it is central to Baidu’s claim to be a full-stack AI company: its third-generation P800 handles the majority of Baidu’s own inference and search-retrieval work and serves the Ernie models. Reuters, citing investment materials, reported the unit expects revenue above 3.5 billion yuan and break-even in 2026, against a roughly 200 million yuan net loss on about 2 billion yuan of revenue in 2024, with external customers, including internet companies, handset makers, telecom operators and state-owned enterprises, accounting for more than half of 2025 revenue. Those are figures shown to prospective investors, not audited disclosures.
Common questions
Is Kunlunxin going public?
It has filed, but nothing is on the public record. Kunlunxin filed a confidential Hong Kong main-board application as a carve-out from Baidu on 2 January 2026, and began STAR Market listing guidance, the mainland pre-filing stage, on 7 May 2026. A confidential filing means no prospectus, terms or audited financials are public, and no listing date has been set on either track.
What is Kunlunxin worth?
There is no filed valuation, and the reported ones are not three estimates of the same thing. Reuters reported on 4 December 2025 that a completed funding round had valued Kunlunxin at 21 billion yuan, about $2.97 billion, which is the only figure investors actually paid; some coverage rendered it as HK$23.11 billion, which reads far larger if the "HK" is dropped. SCMP then reported on 8 May 2026 that the company was seeking at least 100 billion yuan, about $14.69 billion, for its Hong Kong listing, and on 29 June 2026 The Information reported a target near $50 billion, citing two sources, at which point Baidu’s Hong Kong shares rose more than 7 percent and the target was larger than the parent’s entire market value. The last two are pre-filing targets rather than prices, and because the Hong Kong application is confidential, none of them is a filed figure.
What is the Kunlunxin P800?
The P800 is Kunlunxin’s third-generation AI accelerator and the chip that handles the majority of Baidu’s inference and search-retrieval work, including serving the Ernie models. It is reported at about 345 TFLOPS at 16-bit floating point, against about 128 for the previous generation, which puts it in the broad class of Nvidia’s A100 and Huawei’s Ascend 910B. In April 2025 Baidu said it had brought up a cluster of 30,000 P800 chips capable of training models with hundreds of billions of parameters, a company claim that has not been independently verified.
Does Kunlunxin sell chips outside Baidu?
Yes, and increasingly. Reuters, citing investment materials shown to prospective investors, reported that external customers accounted for more than half of Kunlunxin’s 2025 revenue, having been a small share two years earlier. The external base is reported to include internet companies, handset makers, telecom operators and state-owned enterprises, with the P800 adopted in data-center projects led by state-owned enterprises and local governments. Tencent is reported among its customers.
Why were Kunlunxin investors asked to buy chips?
The Information reported that investors in the planned Hong Kong IPO were asked to purchase chips worth three to seven times the value of their intended share subscription. Arrangements that tie an allocation to a commercial purchase are unusual in a public offering. The practical effect is that demand for the stock and demand for the product become hard to separate, and revenue generated this way is hard to read as evidence of independent commercial traction. Kunlunxin has not publicly confirmed the arrangement.
