Ad market upended

Google’s grip on digital advertising is being tested on two fronts at once: new court losses are fueling damage claims, and Meta is projected to pass it in ad revenue. (justice.gov; finance.yahoo.com) On April 17, 2025, United States District Judge Leonie Brinkema ruled that Google illegally monopolized two pieces of the open-web ad stack: publisher ad servers, which websites use to manage ad space, and ad exchanges, which match buyers and sellers. She did not find Google liable in a separate market for advertiser ad networks. (justice.gov; usnews.com) That ruling came after an August 5, 2024 decision by Judge Amit Mehta in Washington, who found Google illegally maintained monopolies in general search and general search text advertising through exclusive distribution deals. The Justice Department later said the remedies court barred Google from maintaining exclusive contracts tied to Search, Chrome, Google Assistant, and the Gemini app. (justice.gov; justice.gov) Those two cases matter to advertisers because they cover both ends of Google’s ad machine: the search ads sold next to results pages and the software plumbing used to place display ads across the web. In the ad-tech case, the next fight is over remedies, including whether Google should be forced to sell assets such as AdX, its ad exchange. (justice.gov; bloomberg.com) The new pressure is not only coming from Washington. Bloomberg Law reported in February 2026 that publishers were filing follow-on suits, and a Google spokesperson said advertisers and publishers choose its tools because they are “effective, affordable and easy to use.” (news.bloomberglaw.com) At the same time, the revenue rankings are shifting. A Wall Street Journal report cited eMarketer projections showing Meta at about $243.46 billion in 2026 net digital ad revenue, ahead of Google at about $239.54 billion. (wsj.com; finance.yahoo.com) The measure is net revenue, which strips out traffic-acquisition and revenue-sharing payments that make gross comparisons less clean. On that basis, Meta’s ad business has been growing faster as marketers spend more on Facebook and Instagram. (finance.yahoo.com; wsj.com) Meta has been pitching that growth with more automation. The Wall Street Journal reported in June 2025 that Meta was building tools to let brands upload a product image and budget, then have artificial intelligence generate creative, target users, and adjust campaigns. (proactiveinvestors.com) Google is still enormous, and it is appealing parts of the antitrust losses. But after two monopoly rulings in less than a year and a new forecast that Meta will lead the market in 2026, the company is defending both its legal structure and its advertising crown at the same time.
