Key Finding

The highest-opportunity topics in 2026 share one pattern: explosive search growth meeting thin course supply. Agentic AI has nearly 500,000 students but exists on just 1 of 11 platforms. Vibe Coding has only 63 courses total. Stoicism has just 14. These gaps won’t last — but right now, early movers face almost no competition.
