Google Spared from AdX Divestment in Latest Antitrust Ruling

Google has been granted immunity from being forced to divest its AdX ad exchange after a federal judge ruled that the company had violated antitrust law. U.S. District Court Judge Leonie Brinkema made this decision in a brief written ruling, stating that while Google did monopolize key components of the market for serving ads on outside publishers' sites, she would order other antitrust remedies instead.

The initial complaint against Google was filed by the Department of Justice and a coalition of states in January 2023. They alleged that Google had corrupted legitimate competition in the ad tech industry by monopolizing markets connected to 'open web display advertising', which essentially means programmatic ads served on sites operated by newspapers and other online publishers.

Brinkema's ruling comes after a three-week trial, during which she found that Google had indeed monopolized the 'publisher ad server market' and the 'ad exchange market'. However, she dismissed a claim that Google had also monopolized the 'advertiser ad network' market. This decision marks another antitrust victory for Google, following U.S. District Court Judge Amit Mehta's ruling in Washington, D.C., where he found against Google in an antitrust lawsuit centered on its search engine.
