Moonshot AI, the Beijing-based developer of the Kimi family of large language models, has confidentially filed for an initial public offering in Hong Kong, according to three people with knowledge of the plans who spoke to Reuters. The report, published on 3 September 2026, said the company is aiming to raise around $3 billion. Chinese technology publication LatePost first reported the filing on 2 September 2026. Moonshot did not respond to a request for comment.
The filing and the numbers
Because the filing is confidential, no public prospectus exists yet. The timetable depends on regulatory approvals, and financial details, including the proceeds sought, could change with market conditions, the sources said. For the listing, Moonshot is working with banks including Goldman Sachs, CICC and Deutsche Bank. CICC did not respond to a request for comment, while Goldman Sachs and Deutsche Bank declined to comment.
The filing lands in an active market. Funds raised through Hong Kong listings totalled $41.2 billion as of mid-August 2026, up 142 per cent year on year, with Chinese technology companies accounting for most of that, according to LSEG data. Among Chinese AI firms, Z.AI, formerly known as Zhipu, and MiniMax listed in Hong Kong earlier in 2026. Anthropic, the developer of Claude, is planning to launch its own offering shortly and complete its listing by October 2026, Reuters reported.
Valuation, backers and Kimi K3
Moonshot has been valued at $50 billion in an ongoing funding round, according to two separate sources. That places it below domestic rivals DeepSeek, which sources have valued at roughly $74 billion, and Z.AI, which has a market capitalisation of $66 billion. The company raised more than $2 billion in May 2026 from investors including Meituan, China Mobile and private equity firm CPE, according to a fundraising document seen by Reuters, bringing total fundraising to more than $5.5 billion. Its investors include Alibaba, Tencent, IDG Capital and HSG, formerly Sequoia Capital China.
Moonshot was founded in 2023 by Yang Zhilin, an AI researcher who pursued doctoral studies at Carnegie Mellon University. Its latest model, Kimi K3, was released in July 2026. Moonshot says the model's 2.8 trillion parameters make it the world's largest open-weight model, and that demand for it has strained the company's computing capacity. Sources have said Moonshot is in talks with Microsoft, Amazon and Google about revenue-sharing agreements that would allow the US cloud companies to host the model. No deal has been announced. If concluded, such an arrangement would be the first major revenue-sharing pact between a Chinese AI firm and a large US cloud provider.
Restructuring for approval
To gain regulatory approval for the listing, Moonshot unwound its offshore incorporation structure, known as a red-chip structure, and re-domiciled onshore in China before filing, according to two sources familiar with the matter.
US scrutiny and the distillation dispute
The IPO comes while Moonshot faces scrutiny from senior US officials over allegations that it used restricted Nvidia chips and distilled capabilities from Anthropic's models. US Treasury Secretary Scott Bessent has said he might add the company to a trade blacklist. Moonshot has disputed claims that Kimi K3's performance was achieved through distillation. As of 3 September 2026, neither the chip allegation nor the distillation allegation had been publicly proven, and no formal blacklisting had been reported in the coverage supplied.
What is established and what is merely claimed
Established on the record: Moonshot was founded in 2023 by Yang Zhilin; its investors include Alibaba, Tencent, IDG Capital and HSG; it raised more than $2 billion in May 2026, taking total fundraising past $5.5 billion; Kimi K3 was released in July 2026; and Hong Kong listing proceeds reached $41.2 billion by mid-August 2026, up 142 per cent year on year.
Claimed by anonymous sources but not confirmed by the company: that a confidential IPO filing has been made, that the target raise is $3 billion, that the ongoing funding round values Moonshot at $50 billion, that hosting talks with Microsoft, Amazon and Google are under way, and that the red-chip unwind was required for approval. Separately, the US allegations about restricted Nvidia chips and distillation from Anthropic's models remain allegations. Moonshot denies the distillation claim, and no public evidence has settled the question in either direction.
