OpenX is a programmatic advertising platform that connects publishers, advertisers, and app developers to buy and sell digital ad space in real time. Ads are traded through an auction-like marketplace where advertisers bid for impressions, and the winning bids deliver ads on display, video, or mobile formats. The platform uses real-time bidding to match advertiser goals with available inventory, aiming to maximize publishers’ revenue while helping advertisers reach their target audiences efficiently. Revenue comes from transaction fees on ad placements and premium services such as advanced analytics and audience targeting. OpenX emphasizes marketplace quality and transparency and uses data and technology to combat ad fraud and improve ad performance. Its goal is to provide a reliable, efficient marketplace that improves outcomes for both publishers and advertisers.

OpenX, a supply-side platform, has launched OpenX IQ, a suite of AI and machine learning capabilities designed to improve media buying quality and performance. The platform addresses growing demand for transparent AI in advertising, with 46% of advertisers planning to use AI for media strategy whilst 35% of marketers cite concerns over AI decision-making transparency. OpenX IQ integrates high-fidelity supply-side signals into media workflows through features including inventory quality scoring, audience modelling, attention and engagement modelling, and performance optimisation. The capabilities are accessible through OpenXSelect and OpenXBuild platforms. Ranked among the largest SSPs globally for direct publisher partnerships by Jounce, OpenX aims to provide buyers with verifiable quality controls and customisable decisioning models across formats including CTV.
Chalice AI has partnered with OpenX to bring AI-powered curation to high-quality video inventory. The integration allows advertisers to deploy custom AI models and bidding agents directly within OpenXBuild, enabling real-time impression-level decisioning at the supply layer. The partnership addresses challenges in video advertising, where marketers struggle to balance quality environments with measurable outcomes amid signal loss and privacy changes. Chalice's AI models operate as always-on bidding agents within OpenX's cloud-native infrastructure, evaluating video impressions based on their likelihood to drive high-value actions. Early results from a Hyundai campaign demonstrated a 20% reduction in cost per high-value action and 67% decrease in CPMs compared to alternatives. The collaboration represents a shift from static curation to dynamic, outcome-based optimisation in premium video advertising.
OpenX, a supply-side platform, has unveiled a rebrand positioning itself as "The Intelligent SSP" with a new logo and visual identity. The company aims to simplify digital advertising by addressing industry complexity that has emerged over the past decade. OpenX introduced a streamlined product architecture comprising OpenXSelect, OpenXBuild, OpenXControl and OpenXExchange, built on three pillars: quality, performance and adaptability. The platform features direct publisher relationships, AI-powered curation and a proprietary supply-side identity graph delivering privacy-forward signals. As one of the largest SSPs globally, OpenX operates on fully cloud-based infrastructure designed to support AI-driven, agent-based buying across CTV, mobile and desktop formats. The rebrand reinforces the company's commitment to transparent supply paths and rigorous inventory standards.
OpenX Technologies has launched OpenX Attention Targeting, the first supply-side platform solution enabling advertisers to target high-engagement CTV inventory in real time. The feature, powered by TVision's attention measurement technology and available exclusively through OpenXSelect, allows pre-bid targeting based on predictive attention scores. The solution combines data from TVision's in-home viewer panel with OpenX's real-time bidstream signals, including time of day, device type and viewing duration. Advertisers can layer attention signals with audience and contextual targeting across 231 million monthly unique users via OpenX's identity graph. The integration transforms attention measurement from a post-campaign metric into a real-time optimization tool. CTV advertising spend is projected to grow nearly 14% this year, driving demand for greater transparency and performance in the fragmented market.
OpenX Technologies has launched a political advertising platform for the 2026 US midterm elections, offering prioritised access to curated, political-approved inventory across connected TV, mobile and web. The platform enables campaigns to go live in under 24 hours with ZIP code-level targeting. The company announced a partnership with Givsly, integrating first-party data from over 500 nonprofits to target voters based on shared values such as environmental protection and women's empowerment. This approach addresses challenges posed by increasingly unreliable traditional political data. The platform features guaranteed access to pre-vetted publishers including Newsweek, Plex and Scripps, with real-time voter reach reporting by county and ZIP code. OpenX provides turnkey political packages optimised for election windows and compatible with major demand-side platforms.
