On July 19, 2026, North American Chinese-language media Kami Zaikei reported on the industry's reaction to the announcement of a new model "Kimi K3" by Chinese artificial intelligence (AI) company Moonshot AI on the 16th.

The article introduced that Kimi K3, which is scheduled to be fully open-sourced by the end of July, has a parameter count reaching 2.8 trillion, making it the world's largest open-source model at present.

In addition, as test results announced by Moonshot AI, Kimi K3 surpassed Anthropic's "Opus 4.8" and OpenAI's "GPT-5.5" in many programming and agent-related benchmarks. It also reported that "GLM-5.2," announced by Zhipu AI (Z.AI), another Chinese company, also surpassed major US models, especially in terms of programming capability, giving the impression of a boost in China's AI technological capabilities.

Furthermore, it mentioned that analysts at major securities firm Jefferies evaluated the Kimi K3 announcement as an "unexpected breakthrough," and JP Morgan's Data Asset Alpha team also analogized the market's reaction to last year's DeepSeek shock, summarizing it as "DeepSeek 2.0-like concerns."

And, it was pointed out that due to the rise of low-cost Chinese-made models, a re-evaluation is progressing among investors regarding the prospects for recouping the enormous investments made by major US tech companies in AI data centers and semiconductors.

The article reported that following the Kimi K3 announcement, stock prices in Asian markets fluctuated significantly on the 17th, with SoftBank Group, one of OpenAI's major shareholders, and Japanese semiconductor manufacturer Kioxia Holdings experiencing a decline in stock prices. Additionally, rival Chinese companies Z.AI and MiniMax Group saw significant drops in China. Furthermore, it reported that the Philadelphia Semiconductor Index also fell in the US market.

In addition, it introduced that although the valuations of Chinese AI companies are still at a lower level compared to their US counterparts, a series of companies have seen rapid increases in the past few months, driven by improvements in technological capability and rising investor demand. It conveyed Taran Chabbra's analysis, who oversees national security policy at Anthropic, stating that "the advantage the US has over China in the AI model field may have already shrunk to about 6-9 months."
