Moonshot released Kimi K3 on Thursday, a model it says matches Anthropic's Claude Fable and OpenAI's GPT-5.6. With 2.8 trillion parameters, it's the largest open model ever released. The model will be available for free download from July 27. The announcement sent US chip stocks into a tailspin: the Philadelphia Semiconductor Index fell 12.5% this week, its worst week in over 15 months, though it's still up more than 60% this year. Nvidia, AMD, and Broadcom all dropped sharply.
A price war on tokens
Moonshot charges $3 per million input tokens. Anthropic's Claude Fable 5 costs $10. The gap gets wider when you look at bigger players. Chamath Palihapitiya noted that a million tokens costs $56 from Anthropic, $26 from OpenAI, and just 50 cents from Chinese labs. Chinese models have already overtaken US rivals in monthly token use. That pricing pressure is real — and it's not going away.
Coding leaderboard shakeup
Kimi K3 topped Arena's coding leaderboard with 1,679 points, pushing Claude Fable 5 into second place. The model can read a million tokens at once — enough to hold an entire codebase in one prompt. Founder Zhilin Yang gave a 40-minute lecture on agent swarms, naming three ways to scale AI: token efficiency, stretch context, and running agent swarms in parallel. That's a lot of ambition packed into one release.
Chip export tensions linger
Washington continues to squeeze chip exports. Nvidia purged Asian chip buyers. Moonshot trained its recent models on Nvidia's export-grade H800 chips — the ones that are still allowed. America still holds the top scores on most major AI benchmarks, but the gap is narrowing. The timing isn't great for US chipmakers. In January 2025, Nvidia lost $589 billion in one day after China's DeepSeek stunned Wall Street. This week feels like a rerun.
Compute derivatives and the next frontier
Bernstein says crypto-style derivatives now trade on AI computing power. CME Group plans compute futures with Silicon Data; ICE announced GPU contracts with Ornn. That's a sign AI compute is becoming a tradable asset — and it's happening fast. Meanwhile, Jim Cramer expressed a lack of trust between the US and China regarding data, saying 'you have to be a first class idiot to let China have any of your data.' That trust gap isn't closing anytime soon.
Moonshot's Kimi K3 will be free to download on July 27. The question now is how US regulators and chipmakers respond — and whether the next big AI breakthrough comes from Beijing, not Silicon Valley.
