AI pharmacy inventory replenishment
Costco reported pharmacy in-stock availability above 98% after introducing AI replenishment
Problem
Costco needed prescription medicines available while keeping purchasing costs low. Pharmacy replenishment also required comparing prices across vendors.
Approach
Costco integrated AI into its pharmacy inventory system. The system compared vendor drug prices and predicted when to reorder stock, placing replenishment orders autonomously. Management described the system as operating in its December 2025 earnings call.
Results
Takeaway
Costco connected purchasing decisions with stock availability. It did not disclose a baseline availability rate or identify the AI supplier.
