- Moonshot AI launched Kimi K3 on Thursday, a 2.8-trillion-parameter open-weight model that scored 57 on the Artificial Analysis Intelligence Index—ranking above Claude Opus 4.8 and GPT-5.5, and on par with Claude Fable 5 and GPT-5.6 Sol while beating them in specific benchmarks at a fraction of the price.
- Semiconductor stocks cratered Friday: Taiwan's benchmark fell more than 6%, Japan closed down 4%, and the Nasdaq slid 1.5% in its worst session of the week.
- The VanEck Semiconductor ETF (SMH) broke below its EMA support band for the first time since April, extending a rout that has put it more than 20% below its late-June record high.
- Full Kimi K3 model weights drop by July 27 under a Modified MIT license, making the model available free to small labs if independent testing confirms the benchmark scores.
- Bernstein's Robin Zhu called the release "confirmatory" of the trend that Chinese AI can keep pace with global state-of-the-art, while Morgan Stanley's Gary Yu described K3 as the product of "steady compound progress" rather than a shock.
- Moonshot is backed by Alibaba, which invested $1 billion at a $2.5 billion valuation in 2024; the startup now sits at roughly $31.5 billion.
- Cursor's Composer 2 was previously found running on Moonshot's Kimi K2.5 without disclosure before the Cursor team acknowledged the open-source base, per Decrypt's May reporting.
Why it matters: If Kimi K3's open weights hold up under independent testing when they drop July 27, U.S. AI labs lose their last credible argument that frontier performance requires frontier spending—the thesis underpinning trillion-dollar chip orders from Nvidia and its customers. The DeepSeek precedent, where Nvidia shed roughly $590 billion in a single session, shows how quickly that thesis can reprice.
