China is rapidly accelerating its AI buildout. As a result, the US and China's AI arms race appears to be at its most intense point yet. Worldwide data center CapEx is now expected to surpass $3 trillion by 2030, and that outlook has nearly doubled since January 2026 alone. Th
Why now
Thesis: Doubling data center capex forecasts imply sustained chip demand
Catalyst to watch: Continued AI capex announcements
Main risk: Capex outlook revision downward
Why it matters
Doubling data center capex forecasts implies sustained demand for chips, power and construction well beyond current estimates.

China is rapidly accelerating its AI buildout. As a result, the US and China's AI arms race appears to be at its most intense point yet. Worldwide data center CapEx is now expected to surpass $3 trillion by 2030, and that outlook has nearly doubled since January 2026 alone. This growth in CapEx expectations is being driven by hyperscale spending, power capacity needs, and rising construction costs. In fact, the top 20 tech companies in the US are now spending 16% of revenue on CapEx, compared to 9% in China. As a result, the US is maintaining its lead on frontier AI models while China is pushing ahead on cost-optimized models and accelerating adoption. The US and China are in the midst of a historic technological competition.
