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.
PubMatic operates an artificial intelligence-powered advertising technology platform that enables real-time bidding and user profiling across the digital advertising supply chain. Its core business involves tracking individuals across websites and mobile applications to build detailed behavioral profiles, which are then used to target advertising. This activity constitutes the development and sale of surveillance infrastructure deployed by third-party advertisers and publishers.
The company faces ongoing litigation alleging systematic violations of federal and state communications privacy laws. A class-action complaint, which survived a motion to dismiss in early 2026, accuses PubMatic of violating wiretap laws and intruding upon seclusion through its online profiling and data tracking practices. A separate securities class action alleges the company made materially false and misleading statements about its business and prospects, with the stock falling 21% following a related disclosure.
While the company provides privacy opt-out tools, its fundamental business model is built on the large-scale collection and analysis of user behavior to facilitate targeted advertising. This positions PubMatic as a provider of surveillance technology—specifically, the intelligence and predictive analytics software used to profile individuals for commercial deployment.

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.
