Amazon is developing Project Tetromino, a proposed generation of highly automated delivery stations that could process packages at roughly 2.5 times the speed of current facilities, according to an internal planning document dated last month reviewed by Business Insider. The plan outlines more than $530 million in capital investment by 2029, starting with a $103 million pilot in 2028, followed by five sites costing about $85 million each in 2029 and 10 more locations in 2030. Amazon disputed the document's financial projections and timeline, describing the project as an early-stage concept. The initiative targets the labor-intensive final-mile tasks of sorting parcels and loading delivery vans, potentially using artificial intelligence and robotics. Boxbot, an AI and robotics supply chain startup, is identified as a potential technology partner; its system uses storage trays and AI to retrieve and sequence packages, and the company says it can make vehicle loading up to 10 times faster. The push forms part of Amazon's broader automation strategy, which includes more than one million warehouse robots, plans to more than double its robotic-arm fleet in 2026, and testing of systems including Proteus, Blue Jay, Vulcan and Digit. The effort comes amid industry-wide investment in logistics automation and continuing debate over employment. Amazon shares rose 1.4% on Monday, taking their year-to-date gain to 13%, while analysts' Strong Buy consensus and average $334 price target imply roughly 27% upside.
