Walmart's Fastest-Growing Business Isn't Retail
Walmart Inc. (WMT) reported a 44% increase in its retail-media division, Walmart Connect, last quarter. Advertising, which has higher margins than retail, now contributes significantly to operational income. U.S. same-store sales growth slowed to 4.1% last quarter, with analysts predicting further deceleration. Walmart is leveraging AI tools and platforms to grow its advertising business.
How this was made

The 30-second read
Why it matters
Traders may focus on whether ad growth and gross margin durability can offset decelerating same-store sales, especially in the lead-up to the scheduled earnings release.
Market read
The article is a pre-earnings narrative emphasizing retail-media as the margin lever, but it does not introduce new company disclosures beyond the stated last-quarter growth rate.
What to watch
The piece cites analyst expectations and rough margin contribution estimates, but does not provide new guidance, ad pricing metrics, or customer-data monetization details that could change the earnings model materially.
Background
Walmart’s core retail growth is described as cooling, while its retail-media arm (Walmart Connect) is highlighted as the faster-growing segment.
Ticker impact
Walmart Connect, its retail-media unit, grew 44% last quarter and is framed as a key profit driver ahead of Walmart’s earnings Thursday.
Moderate upside bias into earnings if investors view ad margins and AI tooling as durable; otherwise limited reaction if retail slowdown dominates.
The newest concrete datapoint is the 44% quarterly growth in Walmart Connect plus margin/profit contribution estimates, but it is still an analysis piece rather than a new earnings print or guidance update.
Market effects
Reinforces the retail-media monetization playbook for large retailers, potentially supporting sector sentiment around ad-driven margin resilience.
Primarily US-focused given the mention of US same-store sales deceleration.
Limited, as the article centers on Walmart’s US retail and its retail-media division.
Counterpoint
Retail-media growth may not fully offset slowing core retail if ad demand softens or if AI/partner platforms increase costs faster than ad monetization.
