Most mid-tier web publishers I spoke to last quarter already gave up on switching away from AdX. The 20% fee stings, but no competing exchange can match the fill rates and real-time bid density Google delivers. Even niche content creators say alternative platforms leave 30% or more of their ad inventory unsold each month. The DOJ’s push to split off AdX felt like the only real shot to break that lock-in, until Wednesday’s ruling landed.
Judge Leonie Brinkema rejected the DOJ’s demand to force a sale of AdX outright. The ruling follows an April 2025 finding that Google illegally monopolized two ad tech markets. Instead of a breakup, Brinkema ordered unspecified behavioral changes to Google’s ad business operations, with the full ruling remaining under seal for now. GOOGL stock climbed 1.01% immediately after the news broke on Wednesday, wiping out nearly all of its minor losses earlier in the trading session.
AdX runs the real-time auctions that sell ad space the second a user loads a webpage. Google controls both the buy-side and sell-side of most ad transactions, so it can skew auction logic to prioritize its own clients and inflate its cut. The DOJ also demanded Google make its ad auction logic public, a request that was also rejected alongside the breakup order. The 20% fee Google charges publishers makes AdX a high-margin business, even if it makes up a small share of Alphabet’s total revenue.
This is the second straight time the DOJ has failed to force an Alphabet asset sale. The first case targeted Google’s search monopoly, and also ended without any structural breakup. Google has a long track record of tweaking operational practices just enough to meet regulatory requirements, without making changes that eat into its core profit margins. Publishers expect the upcoming behavioral rules will do little to break Google’s stranglehold on ad inventory sales.
Wall Street’s bullish stance on GOOGL barely shifted after the ruling. 30 analysts covering the stock have a consensus Strong Buy rating, with 25 Buys and 5 Holds issued in the last three months. The average price target sits at $422.59, implying 23% upside from current trading levels. GOOGL has already gained 45% over the past 12 months, driven by steady ad revenue growth and AI product rollouts. No major analyst downgraded the stock following the court decision.
Google will raise its AdX publisher fees by at least 2 percentage points within 18 months, and no regulator will step in to block the move.
