What Index Exchange does
Index Exchange runs a programmatic advertising infrastructure business focused on the sell side of the market. It creates value by aggregating premium publisher supply, connecting that inventory to broad demand sources, improving auction competition, and providing tools for curation, private deal execution, addressability, and analytics. This infrastructure enables media owners to increase yield and gives buyers more controlled access to inventory and transaction data.
Category differentiation
This is a programmatic sell-side advertising technology company, not a financial securities exchange. It should also be distinguished from buy-side DSPs and from publisher ad servers, although it integrates with both.
Strategic context
AI-supported assessment from the existing company research; distinguish interpretation from sourced facts.
Index Exchange is a Canadian advertising technology company operating an independent global supply-side platform for programmatic media trading. Its core business is helping publishers, app developers, streaming platforms, and other digital media owners monetise inventory through real-time auctions, private deals, curated marketplaces, identity solutions, and transparent analytics. It also serves agencies, advertisers, DSPs, and data partners through curated supply access, deal execution, and measurement capabilities. The company makes money primarily by taking a share of advertising spend transacted through its exchange infrastructure. Its platform spans web, in-app, and CTV/OTT channels and supports display and video formats. Its commercial positioning centres on transparency, unified auctions, transaction-level auditability, and independent marketplace operation rather than ownership of media inventory.
Company news briefing
Briefing updated:
Index Exchange continues to advance its streaming TV capabilities and premium CTV footprint through ongoing collaborations with partners such as VIZIO Ads. The company actively champions sell-side decisioning via Index Marketplaces to bridge media owners and buyers, as demonstrated in thought-leadership series featuring Big Happy and Butler/Till. Furthermore, Index has lent industry support to Google's newly introduced Chrome User Experience Report metrics for assessing ad load.
Business model & monetisation
Index Exchange primarily uses a percentage take-rate model on programmatic advertising transactions flowing through its SSP and exchange. Revenue is generated when inventory is sold via open auctions, private marketplaces, guaranteed deals, curated inventory packages, and related optimisation layers. The platform also embeds monetisable value in analytics, identity connectivity, and marketplace curation, but the overarching pricing logic is transaction-based rather than consumer subscription-driven.

Online Ad Summit 2026: More Agentic, More Open Web?
Agentic Advertising · Recorded impact score: 2/5
The Online Ad Summit 2026, a pre-Dmexco event, focused on the practical implications of agentic AI for the advertising industry. Industry leaders discussed the role of AI agents in media buying, with Sven Wegholz of Publicis Media noting that autonomy is real but scaling is the next step. Andrew Casale of Index Exchange cautioned against overhyping agents, stating they cannot replace programmatic infrastructure. Daniel Knapp of IAB Europe emphasized the need for unified, measurable bundles combining creative, media, and measurement to compete with walled gardens. The event also highlighted the OVK's claim of 32 million activatable identities in Germany, though adoption remains a challenge. Overall, the summit underscored that while agents can streamline workflows, the fundamental issues of the open web, such as reach, frequency control, and measurement, persist.

- Publicis Media's Sven Wegholz stated that agent autonomy is real, but scaling is the next step in agentic media buying.

Google Launches Ad Detection Tool for Chrome Ad Load Assessment
Infrastructure · Recorded impact score: 4/5
Google has introduced four experimental metrics within the Chrome User Experience Report (CrUX) to quantify ad overload and its impact on user experience: ad count, ad density, ad weight by network usage, and ad weight by CPU usage. These metrics offer objective data on the number of ads in the viewport, screen coverage, bandwidth, and processing power, aiding advertisers and publishers in better evaluating ad opportunities and making informed product decisions. The metrics are accessible via the CrUX API, CrUX History API, and CrUX Vis, with future availability on CrUX BigQuery. No benchmarks or thresholds are set, and Google seeks community feedback through a Google Group. Independent ad platforms, including DV360 and Google Ads, will receive equal data access with Google's own ad businesses, ensuring no preferential treatment. Announced by Chrome developer advocates Barry Pollard and Alex Cone, the initiative has support from WPP, The Guardian, Mediavine, Index Exchange, and Adelaide. This move coincides with Google's antitrust challenges and the impact of AI Overviews on publisher traffic.
