WASHINGTON, Feb. 8, 2026 – The Federal trade Commission is investigating whether ad-verification firms and other media rating organizations colluded to boycott conservative media outlets, a lawsuit revealed this week. Integral Ad Science (IAS) is among the 16 entities currently under scrutiny for potentially stifling ad revenue to right-leaning publishers.
FTC Widens Probe into Alleged Advertiser Boycotts
The investigation centers on claims that media credibility groups unfairly targeted conservative platforms, impacting their financial viability.
- The FTC launched its investigation in June 2025, led by Chairman Andrew Ferguson, a Trump appointee.
- IAS is newly identified as being investigated, alongside Global Disinformation Index (GDI) and others.
- GDI alleges the FTC’s inquiry is retaliatory and infringes on its First Amendment rights.
- The probe follows a congressional investigation into alleged ad-spend withholding from conservative media.
The details emerged in amended court filings from the nonprofit Global Disinformation Index (GDI), wich is itself a target of the FTC’s investigation. According to the Feb. 2 filings, IAS is one of 16 non-profit organizations the FTC is seeking facts from regarding a potential advertiser boycott.
The FTC’s Civil Investigative Demands
The FTC initiated the probe last June, issuing civil Investigative Demands (CIDs)-similar to subpoenas-to a range of media credibility groups. These demands required extensive documentation, including years of communications, financial records, and internal reports. GDI argues that the CID it received is a retaliatory measure designed to punish protected speech.
IAS reportedly severed ties with GDI amid the FTC’s scrutiny. In December, the ad-verification firm announced it would no longer utilize GDI’s risk assessments for its context Control Avoidance product. “IAS has determined to discontinue the use of the limited input from the Global Disinformation Index (GDI),” the company stated in a blog post. The two organizations had collaborated sence 2021.
GDI claims that IAS’s decision to end the partnership “may leave all advertisers who use IAS tools less well protected from brand unsuitable content.” IAS declined to comment on the matter, and the FTC has not responded to inquiries.
Broader Scrutiny of Media Rating Firms
While the full list of organizations receiving CIDs remains undisclosed, Media Matters for America and ad Fontes media have also confirmed receiving them. A federal court previously issued a preliminary injunction blocking the FTC from investigating Media Matters, finding the CID to be “a retaliatory act” following the institution’s criticism of Elon Musk. GDI is now pursuing a similar injunction.
On feb. 6, NewsGuard also revealed it received a CID in a new lawsuit against the FTC and Chairman Andrew Ferguson. NewsGuard alleges the agency is attempting to retaliate against and censor the organization, even going so far as to potentially bar ad agency Omnicom from doing business with them.
The FTC’s investigation builds on a congressional inquiry from last summer, which found evidence that members of the Global Alliance for Responsible Media (GARM) may have colluded to withhold ad revenue from conservative outlets like Fox News, The Daily Wire, and Breitbart. This finding prompted X, under Elon Musk’s leadership, to sue GARM and its parent organization, alleging pressure to boycott certain sites. GARM subsequently dissolved.
What is the FTC investigating? The FTC is examining whether media rating firms engaged in coordinated efforts to boycott conservative media outlets, potentially violating antitrust laws and infringing on First Amendment rights.
