TLDR
- Bill Ackman warned that China’s data center expansion could put U.S. democracy at risk if America loses the AI race
- Chinese startup Moonshot released Kimi K3, which topped a coding leaderboard above Anthropic’s Claude Fable 5
- David Sacks called the ranking “concerning,” blaming domestic policy on data centers and model approvals
- Nvidia slipped 2% on Friday; Micron fell into bear market territory on separate chip concerns
- Prediction markets still give Anthropic a 67%+ lead on holding the best AI model by year end
China’s rapid AI build-out is rattling investors and U.S. policymakers, with two high-profile voices now publicly warning that America’s lead is narrowing.
Billionaire investor Bill Ackman posted on social media on July 15 that China is not placing moratoriums on data centers. He warned that the race for superintelligence must be won by the U.S., or the country and its democracy would be at risk.

His comments came after Chinese startup Moonshot released its Kimi K3 model on Friday, July 18. The model reportedly topped the Frontend Code Arena leaderboard, edging out Anthropic’s Claude Fable 5.
David Sacks, who chairs the President’s Council of Advisers on Science and Technology, called the leaderboard result “concerning.” He pointed to domestic policy as part of the problem, specifically moves to block new data centers and proposals requiring regulators to pre-approve frontier AI models.
Ackman responded to Sacks with one word: “Agreed.”
U.S. Policy Creating Bottlenecks
New York became the first U.S. state to pause new data center construction this week. Ackman and Sacks argue that while the U.S. debates energy use and regulation, China is moving forward without those constraints.
Chinese tech giants including Alibaba, Tencent, Baidu, and ByteDance have collectively committed tens of billions of dollars to AI infrastructure by 2027. That investment is the corporate engine behind Beijing’s push, providing the computing power needed to train next-generation AI systems.
Ackman argues that AI leadership, especially at the superintelligence level, will be determined by who controls the most compute, data, and energy. If China reaches that point first, he says it could structurally disadvantage the U.S. in both national security and democratic governance.
Chip Stocks Feel the Pressure
Markets responded quickly to the Kimi K3 news. Nvidia fell 2% on Friday, extending a difficult week for semiconductor stocks as traders questioned how much computing power the AI race will actually require.
The move drew comparisons to early 2025’s DeepSeek moment, when a low-cost Chinese model briefly erased chip valuations before buyers returned.
Micron fell into a bear market this month on separate concerns tied to a rival Chinese IPO and possible export restrictions. It recovered slightly on Friday.
Investor Gavin Baker of Atreides Management offered a more nuanced take. He argued Kimi K3 could benefit most companies while squeezing AI labs that reportedly operate at around 90% inference margins.
Investor Chamath Palihapitiya added that frontier-grade AI output has dropped sharply in price and that model makers’ margins cannot survive it.
Baker pushed back on the cheap-token framing, noting Kimi K3 is verbose and reasoning-heavy, making it 50% to 70% more expensive to run than comparable U.S. models despite lower headline pricing.
Prediction market platform Polymarket still gives Anthropic more than 67% odds of holding the best AI model by year end, with Moonshot in the low single digits.
