Systemwide Scale & the FlywheelWide moat

The franchise model operates at a scale that is itself a moat: roughly $139 billion in systemwide sales, rising 7% in 2025¹, across tens of thousands of restaurants. That scale drives a flywheel. The enormous sales base funds marketing, technology, supply-chain investment, and menu development at a level competitors cannot match; those investments drive traffic and sales; the growing sales fund still more investment; and the whole system compounds. Scale also lowers unit costs across the board — in purchasing, in advertising, in technology development spread across more restaurants — giving McDonald's a structural cost advantage that underwrites its value leadership.

Crucially, the scale is still growing. McDonald's is targeting 50,000 restaurants by 2028, with much of the new-unit capital funded by franchisees, so the systemwide sales base — and the royalty-and-rent income riding on it — keeps expanding without McDonald's bearing most of the cost. Each new restaurant adds to the flywheel's momentum. The caveat, developed in the threat, is that scale in a mature, saturated industry brings the law of large numbers — growth necessarily slows as the base grows, and the recent deceleration in comparable sales shows the system is not immune to a weak consumer. But the sheer scale of the system, and the reinvestment flywheel it funds, is a genuine and widening advantage that smaller competitors simply cannot replicate.
