Costco's AI recommendations drive nearly $1B in sales

Costco's record fiscal year shows a company leveraging AI to modernize its retail model without abandoning its warehouse-club roots. The technology investments, from personalized carousels to demand forecasting, are directly tied to measurable outcomes—nearly $1 billion in digital revenue and a 3x conversion lift—rather than experimental deployments. This practical approach aligns with CEO Ron Vachris's description of AI as "the very Costco way—practical, member-focused and grounded in tangible business value."

Behind the scenes, the Unified Data Platform with Google Cloud and Accenture reduces audience-segment creation from weeks to 30 minutes, enabling real-time personalization. The AI search triple-digit growth, though from a low base, suggests Costco's catalog is now parseable by AI systems, a different kind of SEO for a post-search-bar world. Meanwhile, the Costco Velocity retail media network, launched with Moloco, targets incremental sales using deep neural networks trained on member behavior, aiming to measure genuine new demand rather than shifting credit between channels.

These AI gains support a membership base that funds the technology: executive members, who spend roughly twice as much annually, grew 9.1% to 39.7 million. Renewal rates held at 90% even after the September 2024 fee increase, and digitally-engaged members renew at higher rates. However, Costco is still catching up on in-store tech—scan-and-go improved checkout speed by up to 20% in pilots, narrowing but not closing the gap with Sam's Club. The upcoming September 24 earnings call will clarify whether these investments translate into net income growth and continued AI infrastructure spending.
