InMarket and Basis, the leading intelligent operating system for autonomous advertising, announced a significant expansion of their strategic partnership designed to close that gap.

US retail media advertising is on track to reach nearly $70 billion in 2026 — growing 17.8% year-over-year and outpacing both social and search — yet most media teams still can’t prove what that investment actually drives.

This partnership enhances retail media measurement for Basis users. They now have native access to InMarket’s full suite of outcome measurement capabilities and a collection of unique Retail Media Network (RMN) and incremental lift audiences, comprised of known responders (visits/purchasers) — delivered directly within the platform where media teams already work.

The expanded agreement elevates an existing audience integration into a comprehensive full-funnel offering, connecting ad exposure to real-world visits and sales outcomes across all retailers and RMNs. Incremental sales lift measurement capabilities will also be extended to support clients across the Dining, CPG and Automotive verticals.

What Advertisers Now Have Access To:

• Incremental Visit & Sales Lift Measurement — Basis customers gain direct access to InMarket’s market-leading measurement capabilities to quantify incremental visits and sales lift across all retailers and RMNs, plus incremental sales lift capabilities across the Dining, CPG, and Automotive verticals.
• Unique RMN Audiences — Retail Media Network-specific audience segments built from visitation and commerce data — including buyer types unavailable on RMNs themselves, such as cash purchasers and offline-only buyers — are now accessible through Basis. Clients will also have access to target audiences across RMN for conquesting efforts.
• Lift Optimized Audiences — Basis customers can leverage InMarket’s Lift Optimized Audiences through its platform to plan, activate, and target known visitors, purchasers, and look-alikes — driving measurable incremental outcomes and greater efficiency from every media dollar.
