Making Every Millisecond Count: How Index Cloud Creates More Programmatic Efficiency
Index Exchange announced Index Cloud, an infrastructure offering that shifts decisioning to the sell side by running partner logic inside the exchange auction via cryptographically signed containers. The solution aims to bypass traditional public cloud round trips, significantly reducing latency and expanding QPS capabilities for DSPs and ad tech partners. Currently in closed beta with about a dozen partners, early tests showed a 98% reduction in bid response times for containerized bidders and notable campaign performance gains.
Shifting buy-side and measurement compute directly into the sell-side auction environment represents a major architectural evolution in programmatic advertising, eliminating network round-trip latency and public cloud egress costs.

DSP and SSP Convergence Sparks Rise of UAPs
Karsten Weide of W Media Research argues the long-standing separation between demand-side platforms (DSPs) and supply-side platforms (SSPs) is breaking down as companies combine demand- and supply-side capabilities into unified advertising platforms (UAPs). Examples include The Trade Desk’s OpenPath (DSP→publisher direct) and SSP buying tools such as PubMatic’s Activate and Magnite’s ClearLine. Convergence is most advanced in CTV and premium video, and is being accelerated by privacy changes, retail media growth, and AI (agentic systems). UAPs promise efficiency gains and lower fees but raise structural risks: conflicts of interest, market concentration, reduced transparency, and dependency. Advertisers should diversify and invest in first-party data; publishers should preserve multiple demand paths and manage data-sharing carefully. The industry may consolidate to roughly 10–15 global transaction platforms.
Agency Execs Urge Holistic Retail Media Beyond Lower Funnel
At Digiday's Media Buying Summit, agency executives discussed the evolution of retail media, emphasizing its potential beyond lower-funnel performance marketing. Dentsu's president of commerce for North America, Aisha Khan, highlighted the significant growth opportunity in in-store retail media, noting that over 80% of sales still occur in stores but less than 5% of retail media spend targets in-store. She also mentioned that AI-powered Media Mix Modeling (MMM) could reduce costs and that data CPMs for closed-loop measurement may compress as advertisers build their own measurement capabilities. Instrument CEO Laurel Burton argued that websites remain central to commerce strategy, contrary to predictions of their decline, and stressed the need for cohesive consumer experiences across channels. Crocs CMO Carly Gomez echoed this, emphasizing consistent messaging across websites, social media, and e-commerce. The discussions also touched on the importance of creative in retail media and the potential consolidation of retail media networks.
