Some people are worried about the AI foam and others are afraid of missing out on the investment opportunities of the AI grand narrative, but I have always stressed that the most suitable investment opportunity for retail investors is nonferrous metals In the gold rush in California in 1849, it was not the gold miners who finally made money, but the hardware store owners who sold shovel, the tent merchants, and the service providers who opened pubs The most stable AI gold rush in 2026 will not be big model companies, but rather: ✅ Electricity stocks (AI consumes electricity, whoever provides electricity collects taxes) ✅ Copper aluminum non-ferrous metals (data center infrastructure, demand skyrockets by 170%) ✅ Data center REITs (AI companies are tenants) Looking at the AI game between China and the United States again, what you see on the surface is the competition between ByteDance, Alibaba, Google, and Open AI at the application layer. In fact, let's take a look at the layout at the level of major powers: 中国 China's strategic layout: Silver export controls (effective January 1, 2026.1, accounting for 23.4% of global trade) Comprehensive control of rare earths, gallium, germanium, and antimony (accounting for 60-90% of the global total) What is the function of silver? Core materials for photovoltaic+AI data center US response measures: • Copper inventory of 1 million tons (=world's largest copper mine annual production, decades high) • Copper included in the 'Key Mineral List' The function of copper? AI computing power infrastructure blood (power transmission) The underlying logic of great power games: The physical bottleneck of AI computing power is energy+key mineral supply capacity. Who controls the upstream, who controls the AI endgame. This is also why Musk is optimistic about China's AI industry, because China's infrastructure is too powerful.
