The release of Moonshot AI's Kimi K3 model has triggered a global reassessment of stocks in the artificial intelligence sector. Analysts call this the second shock following DeepSeek, forcing a revision of assumptions about the AI stock market, as the 2.8 trillion parameter model demonstrated that Chinese teams are capable of creating advanced AI solutions at significantly lower costs compared to Western companies.
According to IG market analyst Tony Sikamora, the announcement led to a loss of $314 billion in expected value for private companies OpenAI and Anthropic. Investors began reviewing the competitive dynamics of the foundational AI model market and questioned the effectiveness of US export controls on advanced chips in curbing AI progress in China.
The Chinese semiconductor ecosystem emerged as a winner. SMIC shares rose by more than 5% as increased competition in AI models is expected to stimulate further infrastructure spending. The subsequent announcement of Alibaba Qwen3.8 Max reinforced this trend, causing the ChiNext Composite index to rise by 3.6%.
Portfolio manager Gary Tan of Allspring Global Investments noted that the main beneficiaries remain companies involved in the AI infrastructure layer. China's focus on open-source AI will accelerate the adoption of domestic advanced models, which will require more computing resources and increase demand for basic hardware, especially networking equipment and memory chips.
Memory chip manufacturers are clear winners. Despite the high efficiency of the 896-expert MoE sparse architecture, Kimi K3 still requires about 1.4 TB of memory even after low-precision compression, sustaining constant demand for SK Hynix, Samsung Electronics, and Chinese memory producers.
AI agent and software developers are also benefiting, as cheaper advanced models reduce application development costs and speed up their deployment in coding, customer service, and industrial processes.
Model developers have been losers, facing a sharply deteriorating competitive environment. Zhipu AI, previously considered a leading developer of open models in China, saw its Hong Kong-listed shares drop nearly 40% over two trading days, reflecting market concerns about model-level competition. The announcement that K3 weights will be fully open on July 27th will allow enterprises to run the model independently, without reliance on cloud services, intensifying price pressure across the entire model creation value chain.
Even high-performance chip manufacturers like NVIDIA and AMD face renewed scrutiny regarding the premium pricing they set due to scarcity.
The combination of Kimi K3 and Alibaba Qwen3.8 Max over several days demonstrates that competition in advanced AI models has moved beyond US laboratories. Morningstar analyst Malik Ahmed Khan expressed skepticism about a direct causal link to the sell-off of large technology companies, arguing that American enterprises will not abandon existing cloud providers for Chinese open-source models due to security and regulatory compliance requirements. Nevertheless, the competitive pressure on model pricing and the confirmation of alternative approaches to efficiency represent sustainable changes in the AI investment thesis, requiring a finer distinction between companies benefiting from building AI infrastructure and those whose business models depend on maintaining the scarcity of advanced models.
The Chinese startup Moonshot has introduced the artificial intelligence model Kimi K3. According to the company, this system is capable of processing a significantly larger volume of data per query.
Kimi K3 was developed to perform tasks requiring advanced thinking, complex programming, and intensive operations.
Arthur Igreya explained how Moonshot's new product, Kimi K3, promises to raise the level of artificial intelligence development.
