Why Moonshot matters
Moonshot AI, legally Beijing Moonshot AI Technology Co., Ltd. (北京月之暗面科技有限公司), is a private Beijing lab. Wikipedia groups it with China's "AI tigers" and describes Kimi K3, released in July 2026 at 2.8 trillion parameters, as the largest open-weights model yet. The same article says the company reached a $35 billion valuation by July 2026 and was then the second most valuable privately held AI company in China, after DeepSeek. Yang Zhilin is CEO. The infobox still lists 300 employees in 2026 and headquarters in the JD Technology Building, Haidian.
That valuation is no longer a settled public number. A Bloomberg story dated 5 October 2026, reprinted by Yahoo Finance, said people familiar with the matter believed Moonshot had closed a final private round at about $50 billion and was heading toward a Hong Kong listing in the first quarter of 2027. Moonshot did not comment. Wikipedia, read on 29 October 2026, still records the 30 July 2026 close at $35 billion and does not replace it with $50 billion. The October figure stays an unnamed-source report.
From long context to an open-weight lab
Wikipedia says Yang Zhilin, Zhou Xinyu and Wu Yuxin, school friends from Tsinghua, founded Moonshot in Beijing in March 2023. Yang had worked at Google Brain, Meta and Huawei. The name follows Pink Floyd's The Dark Side of the Moon. Yang's stated goal is foundation models that can reach artificial general intelligence, through long context, a multimodal world model, and a scalable architecture that keeps improving.
Kimi launched in October 2023 with a window of 200,000 Chinese characters. By March 2024 the company claimed 2 million. Alibaba led a $1 billion round in February 2024 at a $2.5 billion valuation and took a 36 percent stake. Tencent and Gaorong joined a $300 million round in August 2024 at $3.3 billion. In July 2025 Moonshot released open-weight Kimi K2, a 1-trillion-parameter mixture-of-experts model with 32 billion active parameters, under a modified MIT license. K2 Thinking, in November 2025, carried company-reported scores of 44.9 percent on Humanity's Last Exam, 60.2 percent on BrowseComp and 71.3 percent on SWE-Bench Verified. Wikipedia dates the next disclosed close, at $35 billion, to 30 July 2026.
K3 and K3.1 Pro
Wikipedia's product list covers the Kimi chatbot, Kimi Researcher, Kimi Agent, Kimi Code, Kimi Audio and Kimina Prover, plus Agent Swarm. It describes K3, released 16 July 2026, as a 2.8-trillion-parameter open model for long-horizon coding, knowledge work and reasoning. Hosts that sell K3 access and generate more than $20 million a year must, under the custom Kimi K3 License, sign a commercial agreement that can include revenue sharing of up to 30 percent.
The K3.1 Pro technical post, read on 29 October 2026, calls Kimi K3.1 Pro a post-trained version of K3 and the company's most capable 3-trillion-class open-weight model so far, with a 1-million-token window. K3.1 Pro Highspeed is offered alongside it. The post says the faster variant runs at about two to three times the speed, while the Chinese API homepage describes it as about three times as fast. Both surfaces say the models are available through Kimi's products and API. The post says full weights will be released by 4 November 2026. Its own Terminal-Bench 4.0 score is 65.7 percent, which it places ahead of GPT-6 Astra at 58.2 percent and just behind Claude Opus 5.5 at 66.4 percent. Those comparisons are Moonshot's. The Chinese API homepage still lists K3 as the previous flagship, at 2.8 trillion parameters, with native vision and a 1 million token window.
What customers pay
On 29 October 2026 the Chinese Kimi API homepage priced K3.1 Pro at 13 yuan per million input tokens, 68 yuan per million output tokens, 13 yuan per million cache-write tokens and 1.30 yuan per million cache-hit tokens. Highspeed was listed at 26 yuan input, 136 yuan output, 26 yuan cache writes and 1.30 yuan cache hits. Wikipedia still records May 2024 consumer plans from 5.2 yuan for four days to 399 yuan a year, and it describes Mooncake as the serving system that processes 100 billion tokens a day. Those subscription and Mooncake figures are older than the October API card.
Wikipedia also says US systems, including Cursor's Composer 2, Thinking Machines Lab's Inkling, Cognition's Devin and Fireworks AI's Ember-1, have used Kimi models as a base or for post-training. It does not state the commercial terms of those uses. The K3 license term is the on-page rule for large inference hosts, not a disclosed revenue total.
The listing, the round, and Recurrent
Wikipedia's infobox still shows $200 million of annualized revenue as of April 2026. Bloomberg's 5 October account says the company reached $300 million of ARR in June, and that people familiar put the current run rate at $1 billion, with $2 billion expected by December. The same account says a previous round this summer valued Moonshot at $31.5 billion, without stating pre-money or post-money, which does not by itself replace the $35 billion close Wikipedia dates to 30 July 2026. Moonshot did not respond to Bloomberg during a Chinese public holiday. None of the October valuation or ARR lines is an on-the-record company disclosure.
Bloomberg said Moonshot had filed confidentially, was considering a raise of up to $5 billion, had added Bank of America as overall coordinator beside China International Capital Corp., Deutsche Bank and Goldman Sachs, and might begin early-look meetings in October, aiming at a first-quarter 2027 Hong Kong listing whose timing might still change. Reuters, in a 12 October story carried by U.S. News, also reported that confidential filing. It said CEO Yang Zhilin and chief technology officer Zhang Yutao were in talks to settle a Hong Kong arbitration brought by Recurrent.ai and some of its investors. The dispute dates from 2024. A letter Reuters saw, and could not independently verify, accuses them of starting Moonshot without Recurrent's board authorization. Recurrent received 9.5 percent of the original shares and is seeking compensation equal to 10.5 percent of those shares, which one person put above $700 million using a $30 billion June valuation. Yang has denied the allegations. Moonshot declined to comment. One person familiar said the fight was not expected to stop the IPO, but that an unresolved case could complicate governance and disclosure. No settlement was known to be imminent.
Oversight and the next tests
Wikipedia records Anthropic accusations, in February 2026 and again on 10 September 2026, that Moonshot used Claude at large scale, including a claim of 5,380 accounts and more than 23 million exchanges, and says the Cyberspace Administration of China opened an investigation that also covers DeepSeek. Bloomberg's October story said it was unclear whether that data-security probe, which it attributed to The Information, would change the valuation or the listing timetable. These pages do not contain a penalty, a closing notice, or a Moonshot reply.
The K3.1 post says Moonshot removed cyber-related data before the planned open-weight release. On its internal xdev-bench-hard, it reports 81.0 percent pass@3 for the released checkpoint versus 90.5 percent for a checkpoint without that removal, and it says offensive cyber capability was kept behind proprietary frontier models that had already been public for at least three months. That is a company evaluation.
The next public tests are whether the K3.1 weights appear by 4 November 2026 and on what license; whether Moonshot, HKEX or a regulator confirms a closed round, an ARR figure and a prospectus; and whether the Recurrent arbitration and the CAC inquiry produce a public result before any early-look meetings and a possible first-quarter 2027 listing.
