Havas joined the Big Six ad cartel on brand safety — the FTC made it the last to settle

Havas Media Group USA LLC was the last of the 'Big Six' advertising agencies to settle with the FTC over a coordinated scheme to impose uniform brand safety standards across digital advertising. The six agencies — WPP, Publicis, Dentsu, Omnicom, IPG and Havas — had agreed not to compete on which content was safe for advertisers, removing the competitive pressure to offer differentiated or cheaper brand-safety services.

The FTC alleged the collusion led to the systematic demonetisation of disfavoured political viewpoints. By setting common standards, the agencies insulated themselves from clients who might have wanted a more permissive or more restrictive approach, and from publishers whose content was excluded from the standard. The complaint was filed jointly with eight states.

Havas agreed to a consent order in June 2026 prohibiting it from entering agreements that set common brand safety standards or restricted advertising based on biased or politically motivated criteria. The order was approved by a federal judge. The earlier settlements with WPP, Publicis and Dentsu were reached in April 2026; Omnicom and IPG resolved related allegations in September 2025 during their merger review.

Havas settled last with a consent order barring common brand-safety pacts, ending the cartel that insulated agencies from market pressure.

Brand safety standards are a competitive lever — standardising them across the Big Six let each agency protect its revenue from a rival who might offer a narrower or cheaper filter.

The collusion was industry-wide rather than bilateral, making it harder to detect: every agency enforced the same standard, so no advertiser saw a discrepancy that would trigger a complaint.

Demonetising political viewpoints turned a competition case into a reputational crisis, and the eight states that joined ensured political weight beyond a routine antitrust fine.

Industry-wide agreements on 'safe' content remove competitive pressure to improve — and turn every participating agency into a defendant when the political consequences surface.
