Boeing vs RTX Corporation: Which Is the Better Buy in 2026?

Boeing earns most of its value from commercial aircraft — a cyclical business tied to airline capex budgets, travel demand, and aircraft replacement cycles. RTX earns from defense procurement (Raytheon Missiles & Defense, roughly 40% of revenue), aircraft engines (Pratt & Whitney, commercial exposure), and aerospace systems (Collins Aerospace). RTX's commercial exposure through Pratt engines creates some correlation to Boeing's market, but its defense revenue provides stability Boeing's model doesn't have. Boeing's execution risk is company-specific; RTX's risks are more macro and program-level.

RTX's revenue mix is more defensive — Raytheon missiles and Collins Aerospace equipment are deeply embedded in government program budgets with multi-year procurement visibility. Boeing's commercial aviation franchise has more long-term upside if execution recovers, but every earnings cycle requires explaining new delays, quality issues, or program overruns that have eroded investor confidence. RTX for a stable aerospace and defense compounder; Boeing for a higher-risk turnaround with significant upside if its manufacturing problems finally get resolved.
