The AI Industrial Revolution Is Here: 5 Sectors Built to Weather the Storm in 2026

The artificial intelligence trade has entered a new phase — and it's not about chatbots anymore.

After two years of speculative hype, the AI investment thesis has matured into something far more concrete: a massive industrial buildout that's reshaping everything from power grids to memory chips.
