We just covered Bill Gates’ 2026 Portfolio: Top 10 Stocks to Buy. Canadian National Railway (NYSE:CNI) ranks #3 (see the Bill Gates’ 2026 Portfolio: Top 5 Stocks to Buy).

Canadian National Railway (NYSE:CNI)’s moat is strong because it hauls essential goods like grain and fertilizers to intermodal freight through its coast‑to‑coast rail systems in the Pacific, Atlantic and Gulf of Mexico. This network allows Canadian National Railway (NYSE:CNI) to bypass the congested Chicago hub more efficiently than competitors. Its moat is strong because it’s nearly impossible to replicate this transcontinental rail infrastructure today due to regulatory and environmental hurdles.

The stock is trading at roughly 17–18x forward earnings, below its 10-year average of 19.4x.
