Scintilla (formerly called Walmart Luminate) is an analytics platform Walmart offers to the brands and suppliers who sell on its shelves. It gives them access to data about how their products sell at Walmart stores and online, and uses AI to suggest what they should do next — like how to adjust pricing or fix a stock issue. Suppliers who subscribe to it grew their combined sales 15% faster than those who don't.

Scintilla was rebranded from Walmart Luminate in late 2024. The platform is operated by Walmart Data Ventures, a dedicated unit within Walmart. As of 2025, Walmart is evolving the platform from showing historical data to offering AI-driven forward-looking recommendations for suppliers and merchants. At its October 2025 Inspire supplier event, Walmart announced an upcoming "intelligent data companion" — a conversational AI tool — that will allow suppliers to ask questions about their metrics and receive tailored recommendations directly. The broader data infrastructure behind the platform, known internally as the Data Café, processes more than 200 billion rows of transaction data from over 200 different sources.
