The Costco Playbook: Scale Economics Winners (October 2026)
Scale economics businesses.
Charge less, earn thin margins on purpose, and let scale turn volume into a moat. Fifty companies on our list run the Costco playbook, and the current best expression is Chinese hotelier Atour, with an MGI of 72 at a $5B cap, tied with HEICO, the $38B aerospace parts compounder. Shopify at $154B and MercadoLibre at $88B prove the model travels.
Reading scale-economics names means forgiving the gross margin and watching operating leverage instead; the archetype wins by improving economics as it grows, not by pricing power. The median MGI of 65 puts this group a notch below the asset-light elite, which is the point: these compound the hard way. Click any name for the full citation-backed analysis.
