Executive Summary

Walmart's advertising revenue growth rate is outpacing Amazon's as of early 2026, signaling a major shift in retail media budget allocation. This directly impacts sellers and agencies deciding where to invest ad spend across both platforms.

Our Take

When a platform's ad revenue grows faster than the market leader's, CPCs and competition follow — Walmart Sponsored Products auctions are getting more competitive, not less. Pull your Walmart campaign ACOS/ROAS trends from the last 90 days now before efficiency degrades further.

What This Means

Retail media is consolidating into a two-platform duopoly — Amazon and Walmart — compressing advertiser efficiency on both as budgets flood in. Agencies and brands without Walmart ad infrastructure are now competitively behind.

Key Takeaways

Check Walmart Campaign Manager > Performance Reports -- if ROAS has dropped >15% QoQ, shift budget to lower-funnel Sponsored Products before new advertiser competition floods upper-funnel placements.

In the next 30 days, establish Walmart DSP baseline benchmarks so you have pre-saturation data to compare against as more brands enter the platform.

Bottom Line

Walmart ad growth surge means rising CPCs and tighter margins for current Walmart advertisers.
