What "Amazon Supply Chain Services" Tells Us About What Amazon Is

# Summary Amazon launched Amazon Supply Chain Services in May 2026, opening its logistics network to external enterprise customers like Procter & Gamble and 3M—following a proven pattern Amazon has executed twice before with Amazon Marketplace and AWS. The move represents the third time Amazon has monetized internal infrastructure it built at a scale no external competitor could justify, turning it into a profitable external business once marginal costs undercut the customer's internal alternative.
