This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
Magnite operates a programmatic advertising platform that collects, analyzes, and monetizes detailed data on individuals' online behavior across desktop, mobile, and connected TV (CTV) environments. This business model is built on the large-scale tracking of web browsing, app usage, and viewing habits to enable targeted advertising. While the company describes its practices under "Responsible Advertising and Data Governance," its core service involves the aggregation and sale of behavioral data.
In May 2025, Magnite was sued in a proposed class action alleging it tracked consumers' online behavior without adequate consent and then de-anonymized and sold this data. The lawsuit claims these practices constitute surreptitious data collection. This follows a 2021 report by Spruce Point Management that detailed the company's "dubious business practices." Magnite's technology enables AI-driven contextual signaling and audience targeting, which are forms of predictive analytics used to infer user characteristics and intent—a capability that aligns with the surveillance technology category's inclusion of intelligence and analytics software built for deployment by third parties.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
This information is provided for educational and transparency purposes only and should not be relied upon as investment advice. Data is drawn from independent watchdogs, NGOs, government registries, and Ethical Capital's ongoing research — see Research Sources for the full list.
