On July 16, Moonshot AI unveiled the Kimi K3 model with a colossal 2.8 trillion parameters. This release triggered a massive sell-off in the global semiconductor market, creating a domino effect that impacted shares of chipmakers and AI companies worldwide.
On Friday, Asian markets were hit particularly hard: the Taiwanese index fell by more than 6%, while the Japanese market closed down 4%. In the US, the sell-off continued, with the Nasdaq losing 1.5%, marking its worst performance in a week. Shares of Chinese AI developer Z.ai plummeted nearly 30% in Hong Kong, and Nvidia temporarily ceded its title as the world's most valuable company to Apple.
Repetition of the "DeepSeek Effect"
Investors drew parallels to January 2025, when the launch of DeepSeek's R1 model led to Nvidia losing approximately $590 billion in market capitalization in a single session. Kimi K3, the largest open-source model at the time of its launch, scored 57 points in the independent Artificial Analysis Intelligence Index, surpassing Claude Opus 4.8 and GPT-5.5, and nearly matching Claude Fable 5 and GPT-5.6 Sol.
Particular attention was drawn to its price: in certain tests, Kimi K3 outperformed competitors at a fraction of the cost. The model supports a context of 1 million tokens, handles text and images, and its full weights will be released on July 27 under a Modified MIT license, allowing smaller labs to use it for free.
Analysis of Market Reaction
Wall Street analysts largely anticipated such consequences. Morgan Stanley described K3 as the result of steady progress rather than a shock. According to expert Gary Yu, Chinese LLMs are comprehensively catching up to US leaders in size, performance, and price. Bernstein called the release "confirmatory": AI is developing rapidly, and China is keeping pace.
However, some experts consider the sell-off excessive. According to their data, K3's price is close to GPT-5.6, not radically lower. The downturn also affected cryptocurrencies: Bitcoin fell below $64,000. A broader sell-off in the chipmaker market has been ongoing for several weeks amid concerns over valuations of companies tied to AI infrastructure.
The Philadelphia Semiconductor sector index is more than 20% below its late June record, formally indicating a "bear market." The VanEck Semiconductor ETF, a barometer for the entire sector, broke through a key moving average for the first time since April in early July. The release of Kimi K3 only accelerated the decline.
My analysis: The market is clearly overestimating the threat from Kimi K3. Chinese models are indeed catching up to Western ones, but their price advantage is not yet a decisive factor for global dominance. The decline is more of a correction following sector overheating than the start of a long-term trend. Investors should reassess their positions but not panic.
