Walmart Connect vs Amazon Ads: Where to Start and How to Scale in 2026
Retail media has become among the most influential profit levers for brands selling through the major US marketplaces. In 2026, Amazon Ads and Walmart Connect control retail media investment decisions, but they function very differently in terms of how they drive demand, allocate costs, and drive long-term profitability. Choosing where to start—and how to scale—requires a clear understanding of unit economics rather than surface-level performance metrics.
AdOrbix works with brands to assess retail media platforms through the lens of profitability first, ensuring ad spend strengthens contribution margin rather than masks underlying cost pressure.
Understanding the structural differences between Amazon Ads and Walmart Connect
Amazon Ads is much more mature and competitive than most auction environments; huge shopper demand and advanced targeting enable brands to scale immediately with strong conversion rates. However, rising CPCs and margin compression come with increasing competition. By contrast, Walmart Connect is still in its development and is less saturated within an ad ecosystem. While it does not provide the sophistication of targeting and reporting like Amazon’s, Walmart Connect does grant access to a large, value-oriented customer base and stronger omnichannel measurement.
Comparing Ad Economics Beyond ROAS
Comparing Amazon Ads to Walmart Connect using identical ROAS benchmarks is one of the most common mistakes a brand can make. Amazon Ads often report higher ROAS because they capture high-intent shoppers who are closer to conversion. Walmart Connect frequently shows lower ROAS, but with a much higher proportion of incremental sales and new customer acquisition.
AdOrbix reimagines performance optimization by modeling contribution margin post-advertising, including wholesale discounting, fulfillment costs, chargebacks, and returns. The outcome of this is often that a lower ROAS campaign actually yields higher net profit than what seems to be a far more efficient alternate.
Scaling Amazon Ads Without Destroying Margin
Scale Amazon Ads in 2026 with far more precision than simply increasing the budget. Rising CPCs, combined with aggressive competitor bidding, mean that inefficient spending is punished very quickly. The brands that scale their ad spending on Amazon with success segment campaigns by intent, separate defensive spending from growth initiatives, and cap bids based on SKU-level margin thresholds.
AdOrbix ties Amazon Ads planning together with Vendor Central negotiations, pricing strategy, and Seller Central economics. This ensures that advertising is supportive of overall account profitability, rather than compensating for structural pricing or term weaknesses.
Scaling Walmart Connect the Right Way
Scaling Walmart Connect is less a function of cost and more a function of operational readiness. In-stock rates, speed to fulfill, and pricing consistency heavily influence ad performance. Brands looking to scale media before these fundamentals are in order often misinterpret performance signals and underutilize the full potential of the platform.
AdOrbix aligns Walmart Connect investment with supply chain readiness and merchandising strategy, ensuring ad spend is converted into sustainable volume instead of temporary spikes.
Building a Complete Retail Media Strategy
The most profitable brands in 2026 don’t look at Amazon Ads and Walmart Connect as competitive channels. Instead, they use Amazon to capture high-intent demand at scale and Walmart to drive incremental reach and efficiency. These approaches demand a unified measurement, profitability models shared across the business, and decision-making consistency across platforms.
AdOrbix develops integrated retail media frameworks to help brands connect the dots between ad performance and pricing, logistics, and trade terms for confident scaling without giving up margin.
