Index Exchange Opens Cloud to DSPs for In-Exchange Bidding
Index Exchange announced Index Cloud, a neutral compute environment that lets demand-side platforms run bidding logic inside its exchange. The move aims to reduce costs and improve efficiency in programmatic auctions while fostering healthier competition among DSPs. The first DSP to pilot the offering is Bedrock Platform, an AI-centric DSP founded about two years ago; Bedrock has been testing transactions in the new setup for roughly a week and a half. Index Exchange positions the capability as a way to bring the buy side closer to sell-side inventory and streamline auction workflows.
Introduces a new in-exchange compute model that could reduce bidstream friction and costs and influence programmatic auction dynamics and DSP competition, but it is not from a hyperscaler or a regulatory change.

Index Exchange moves bidding into its own cloud
Index Exchange has launched a new infrastructure layer — branded as a private cloud environment — that lets programmatic partners run their data, models and bidder logic inside the exchange. The setup aims to move decisioning closer to the auction/impression to reduce latency, avoid signal loss, and remove routing through external public clouds. Bedrock Platform is the first demand‑side platform to operate its bidder directly inside Index Exchange’s infrastructure, which Index Exchange says increases reachable inventory by removing QPS limits and traffic‑shaping restraints. The environment is multi‑tenant but isolated (partners cannot access each other’s code or data) and only final bidding decisions are shared with DSPs. Index Exchange says the design aligns with the IAB Tech Lab’s Agentic Real‑Time Framework to support standardized containerized integrations in exchanges.
