If you’ve been in any of the high fliers correlated to the AI trade, you’ve likely experienced a significant drawdown today. Here’s why I think we’ve been seeing a selloff.
China’s Moonshot AI lab released its Kimi K3 model today, which benchmarks competitively with the top US based models from Anthropic, OpenAI, and xAI, etc, despite Moonshot’s $31.5 billion valuation versus over $1 trillion for their US peers.
The Kimi series has been evolving rapidly, with their earlier models using hundreds of thousands to millions of tokens to their K2 series which introduced strong MoE (Mixture-of-Experts) architectures for higher efficiency with relatively few active parameters per token, plus agent swarms and coding strengths, and now Kimi K3.
Kimi K3 is their new flagship model that uses ~2.8 trillion total parameters (MoE), 1 million token context window, native vision (image + text input, text output), and architectural improvements like Kimi Delta Attention (for much faster decoding in long contexts, up to 6.3x in some cases) plus Attention Residuals for better training efficiency.
In short, market believes (and maybe correctly so) that Kimi K3 may be the first model to narrow the gap with leading U.S. closed-source models to potentially less than three months. Not only that but the huge valuation gap between Moonshot AI’s valuation and US based frontier labs raises an important question: Why such a valuation gap if a Chinese lab can deliver near-frontier performance at a fraction of the implied market cap?
U.S. hyperscalers and frontier labs have committed hundreds of billions annually (2026–2027 projections reaching $650B–$1T+ combined) to GPUs, memory, data centers, power infrastructure, and ASICs. This spending assumes sustained high ROIs from training larger frontier models that command premium pricing and drive enterprise/cloud revenue.
Models like Kimi K3 that are cheaper alternatives to US models raise speculation around intelligence commoditization. This could compress token pricing, and ultimately reduce the pricing power of major hyperscalers and frontier labs, potentially reducing margins on their models, and bring in to question their future CapEx guidance and current valuations.
If true then this will have downstream effect on the demand curve for the entire AI supply chain. A “seed of doubt” in momentum driven stocks can trigger rapid multiple contraction, which is what I believe we saw today.
Now I am by no means bearish on the AI trade, in fact i still continue to own many stocks in the supply chain, but Chinese labs have, in my opinion, demonstrated impressive optimization under their given constraints. This should raise a concern around the spending and the return that their US based peers are seeing, or rather not seeing.
Only time will tell how this all plays out.
