Moonshot AI Raises $3.5B Series F as Kimi K3 Model Accelerates B2B Revenue

Beijing-based AI startup Moonshot AI has completed a Series F funding round exceeding $3.5 billion, pushing its post-money valuation to $35 billion, according to reporting by Securities Times. Driven by market reaction to its newly released Kimi K3 model, the oversubscribed round closed ahead of schedule, prompting the company to begin its Series G pre-IPO fundraising at a target valuation of $50 billion. Moonshot AI's annualized recurring revenue crossed $300 million in June, with enterprise API calls accounting for more than 70% of total revenue.

Moonshot AI's rapid funding trajectory demonstrates strong investor demand for Chinese AI platforms capable of converting technical model benchmarks into enterprise revenue. The company's growing reliance on B2B API revenue and mixed hardware deployment strategies reflects how China's AI sector is adapting to tight compute supplies while shifting away from consumer subscription models.

Chinese artificial intelligence startup Moonshot AI has closed an oversubscribed Series F funding round exceeding $3.5 billion, raising its post-money valuation to $35 billion, according to reporting by Securities Times. Strong investor demand forced an early close to the round, prompting the company to launch its Series G pre-IPO fundraising ahead of schedule with a pre-money target valuation of $50 billion. The funding acceleration follows the release of Moonshot AI's flagship Kimi K3 model, a 2.8-trillion parameter open-source system that achieved top scores on the Frontend Code Arena programming benchmark and topped community trending lists shortly after launch. Securities Times reported that Moonshot AI President Zhang Yutong disclosed multi-fold rapid growth in enterprise annualized recurring revenue (ARR) following the release. Moonshot AI's financial performance highlights a clear transition from individual consumer subscriptions to enterprise B2B monetization. The company's ARR expanded from $100 million in March 2026 to $200 million in May, crossing $300 million by mid-June. API integrations now generate more than 70% of total Kimi revenue and continue to rise. Meanwhile, consumer-facing operations faced infrastructure constraints, with Yicai reporting that Moonshot AI temporarily suspended new individual subscriptions in July due to compute power shortages. To manage compute bottlenecks, domestic developers are optimizing engineering efficiency and testing alternative chip architectures. According to Yicai, Moonshot AI's K3 testing environment spans Nvidia H200 GPUs as well as GPGPUs from non-Nvidia vendors, alongside prototype development for specialized inference hardware. The $3.5 billion Series F represents the second-largest single fundraising round for a Chinese LLM enterprise, trailing only DeepSeek's funding round in June. Industry statistics cited by Securities Times show Moonshot AI's cumulative fundraising has passed 37.6 billion yuan. Venture investors note that while valuation multiples are high relative to current traditional earnings, pricing reflects market confidence in Moonshot AI's potential to remain a core, sustainable AI platform.
