The VanEck Semiconductor ETF fell below key support for the first time since April, as investors feared Chinese AI progress could undermine U.S. infrastructure spending. Full model weights will be released by July 27, potentially intensifying competitive pressure on American AI companies.", "body_md": "#### In brief\n\n- Moonshot AI launched Kimi K3 on Thursday—a 2.8-trillion-parameter open-weight model that ranked alongside Claude Fable 5 and GPT 5.6 Sol.\n- Semiconductor stocks cratered Friday, with the VanEck Semiconductor ETF (SMH) falling below key support for the first time since April.\n- Full model weights go public by July 27. If they hold up under independent testing, the pressure on U.S. AI companies to justify their infrastructure spending gets significantly harder to dismiss.\n\nChina did it again. Moonshot AI launched [Kimi K3](https://www.kimi.com/blog/kimi-k3) in the dead of night and markets woke up today doing what they always do when a Chinese lab closes the gap: They panicked.\n\nSemiconductor and AI stocks dropped across the board Friday. Taiwan's benchmark fell more than 6%. Japan closed down 4%. The Nasdaq slid 1.5%, its worst session of the week.\n\nThe [DeepSeek comparison](https://decrypt.co/302982/why-china-deepseek-ai-blowing-minds-markets) seems well deserved. When DeepSeek dropped R1 in January 2025, the assumption that frontier AI required frontier spending—and the chip orders to match—cracked overnight. Nvidia shed around $590 billion in market cap in a single session. This time the damage spread across the sector.\n\nThe VanEck Semiconductor ETF (SMH) fell below its EMA support band—the moving average tracking the price trend over the prior months—for the first time since April, extending a rout that has put it more than 20% below its late-June record high.\n\nOn the Artificial Analysis Intelligence Index—an independent composite benchmark that aggregates model performance across reasoning, knowledge, mathematics, and coding—K3 scored 57, ranking above Claude Opus 4.8 and GPT-5.5, practically on par with Claude Fable 5 and OpenAI's GPT-5.6 Sol, beating them in specific benchmarks at a fraction of the price. Full weights drop July 27 under a Modified MIT license which means small labs will have that model available for free.\n\nWall Street analysts largely saw this coming. Bernstein's Robin Zhu called the release \"confirmatory\"—another data point in a trend that's been building all year. Morgan Stanley analyst Gary Yu [framed](https://finance.yahoo.com/technology/ai/articles/kimi-k3-ai-breakthrough-wall-123003909.html) K3 as the product of steady compound progress rather than a shock. \"K3 has received positive feedback globally, signaling an all-round catch-up of Chinese LLMs with U.S. leaders in model size, performance, and pricing,” he wrote.\n\nBernstein analyst Robin Zhu also framed this as a catch-up. “At a high level, K3 feels confirmatory of our views that (1) AI [state of the art] continues to evolve rapidly; and (2) China AI can continue to keep pace with global [state of the art], and take some share over time.”\n\nMoonshot is backed by Alibaba, which put $1 billion into the company in 2024 at a $2.5 billion valuation. The startup now sits at roughly $31.5 billion.\n\nAs [Decrypt covered in May](https://decrypt.co/367916/kimi-webbridge-ai-agents-browser-local), Moonshot already has deeper roots in U.S. developer circles than most realize—Cursor's Composer 2 was found to be running on Kimi K2.5 without disclosure before the Cursor team acknowledged the open-source base.", "url": "https://wpnews.pro/news/kimi-k3-just-triggered-deepseek-flashbacks-for-the-stock-market", "canonical_source": "https://decrypt.co/373736/kimi-k3-triggered-deepseek-flashbacks-stock-market", "published_at": "2026-07-17 17:55:32+00:00", "updated_at": "2026-07-17 18:02:34.378871+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-startups", "ai-policy", "ai-chips"], "entities": ["Moonshot AI", "Kimi K3", "DeepSeek", "Nvidia", "VanEck Semiconductor ETF", "Alibaba", "Bernstein", "Morgan Stanley"], "alternates": {"html": "https://wpnews.pro/news/kimi-k3-just-triggered-deepseek-flashbacks-for-the-stock-market", "markdown": "https://wpnews.pro/news/kimi-k3-just-triggered-deepseek-flashbacks-for-the-stock-market.md", "text": "https://wpnews.pro/news/kimi-k3-just-triggered-deepseek-flashbacks-for-the-stock-market.txt", "jsonld": "https://wpnews.pro/news/kimi-k3-just-triggered-deepseek-flashbacks-for-the-stock-market.jsonld"}}
