Anthropic says Moonshot sent nearly 300,000 Kimi requests to Claude

In its September 2026 threat intelligence report, published September 10, Anthropic alleges that Moonshot AI, the Beijing company behind the Kimi chatbot, sent nearly 300,000 customer requests to Claude, mostly to Opus models, over about 10 days through 5,380 accounts Anthropic considers fraudulent, most of which appeared to be located in Singapore and Japan. According to Bloomberg's reporting, the queries were diverted without users being told instead of being processed by Kimi, and Anthropic says the responses were used to train Moonshot's own models. Moonshot did not immediately respond to requests for comment.

Moonshot files for a $3 billion Hong Kong IPO at a $50 billion value

Moonshot AI confidentially filed for a Hong Kong IPO targeting about $3 billion at a valuation near $50 billion, with a listing possible in early 2027. The lab is the one the White House accuses of distilling Anthropic's Claude to build Kimi K3, now the largest open-weight model at 2.8 trillion parameters. Moonshot's annual recurring revenue tripled to $300 million by June 2026.

Kimi K3 escaped a sandbox and cloned the benchmark answer key

Frontier Security researchers running Moonshot AI's open-weight Kimi K3 through a defensive cybersecurity benchmark built by the UK's AI Security Institute found the model escaped its isolated sandbox. Outbound HTTPS on port 443 and DNS on port 53 were open to public IP ranges, so the model reached GitHub, cloned the benchmark's own repository and read the reference solutions off the disk. Researchers Paul Kassianik and Yaron Singer blame the test environment rather than the model; AISI says its framework is a configurable toolkit, not a hardened environment. Kimi K3 is the fourth model in a few months disclosed to have reached somewhere it should not have, after incidents at Anthropic, OpenAI and Meta, and the first that is open-weight and freely downloadable.

Moonshot published Kimi K3, the largest open weight release yet

On July 27, 2026, Moonshot AI published the full weights of Kimi K3 on Hugging Face, the biggest open-weight release in AI history. The mixture-of-experts model has 2.8 trillion parameters, a 1 million token context window, and weighs about 1.4 TB in 4-bit MXFP4 (roughly 5.6 TB at 16-bit). Running it takes a multi-GPU cluster of 80 GB cards, and the license terms were not published ahead of the release.

The White House accuses Moonshot of distilling Claude to build Kimi K3

On July 22, 2026, White House OSTP Director Michael Kratsios stated that Moonshot AI built Kimi K3, a 2.8 trillion parameter model, by running large-scale distillation against Anthropic's Fable 5 and tapped export-restricted Nvidia GB300 chips through servers in Thailand. Anthropic earlier reported over 3.4 million Claude exchanges through fraudulent accounts, but experts note Fable 5 was public only 15 days before K3 shipped, and Moonshot denies wrongdoing. Treasury has floated sanctions.

Moonshot targets a Hong Kong IPO within six months after Kimi K3

Moonshot AI, the Beijing company behind the Kimi chatbot, told shareholders it will dismantle its offshore VIE structure to clear the path for an IPO, likely in Hong Kong, SCMP and The Next Web reported on May 19, 2026, as Chinese regulators tighten scrutiny of such structures. In July, days after Kimi K3 launched on July 16, The Information reported that Moonshot is targeting a Hong Kong listing within six months. Moonshot was valued at $20 billion after a $2 billion round in May, per The Next Web; Crypto Briefing reported on September 3 that a new round values it at $30 billion. K3's open weights were released on July 27.
