NEW YORK, September 6, 2026, 4:05 a.m. EDT — Alphabet Inc. NASDAQ:GOOG finished Friday at $335.31 after Google escaped a forced sale of its AdX advertising exchange. The ruling removed a breakup threat, while leaving the cost of the remedy hidden.
The shares gained 0.5% when the decision landed Wednesday. They added 1.6% Thursday, then surrendered most of that move Friday. Google still faces behavioral restrictions in a business whose economics are thinly disclosed.
The court bounce did not hold

U.S. District Judge Leonie Brinkema rejected the Justice Department’s structural remedy Wednesday. Google can keep AdX and its publisher ad-server business, according to the Associated Press.
That is the clean win. The rest is harder to price. Brinkema’s full opinion will stay sealed for 14 days while the parties propose redactions.
Google regulatory affairs vice president Lee-Anne Mulholland welcomed the decision. “We’re very pleased the Court rejected the DOJ’s proposal to break apart tools that help small businesses reach new customers and grow,” she told AP.
One threat is gone. The operating rules are unseen.
The public outcome compared with each side’s requested remedy.

The sealed pages matter more than the relieved headline. Google had proposed narrow interoperability changes. Prosecutors wanted nondiscrimination rules, data access and outside monitoring alongside divestitures.
A technical decree could alter auction routing or reveal rival bids. It could also curb Google’s use of publisher data. Those details determine whether publishers merely gain options or shift meaningful spending away from Google.
Alphabet reports the neighborhood, not AdX
Second-quarter 2026 revenue mix. The Google Network line is the nearest disclosed proxy.

The missing line item
AdX revenue: undisclosedThe $7.30 billion Network category also includes AdMob and AdSense. It represented 6.1% of Alphabet revenue and 8.9% of Google advertising revenue.
Source: Alphabet’s quarterly filing. Percentages use company figures and TS2 calculations. Other operations are the remainder of total revenue.
The accounting boundary sets a ceiling, not an exposure estimate. Google Network generated $7.30 billion last quarter. That category combines Ad Manager with AdMob and AdSense, while AdX alone remains invisible.
Network revenue slipped 0.7% from a year earlier. Impressions fell 12%, although pricing rose 13%. The mix suggests fewer auctions were already carrying more revenue per impression.
Behavioral rules may pressure that pricing offset. A wider flow of real-time bids could strengthen rival exchanges. Data-sharing limits could also weaken Google’s matching advantage.
There is an opposite case. Better interoperability may keep publishers inside Google Ad Manager. Search and YouTube produced $74.33 billion last quarter, providing a much larger earnings cushion.
The next valuation signal will come from the unsealed opinion. Investors should look for auction access, data portability, monitoring costs and the decree’s duration. Appeal language will shape the timetable.
Risks: The sealed order may prove tougher than the initial notice suggests. Private advertiser claims or overseas cases could raise the legal bill. A successful appeal could delay relief, while weaker ad demand would obscure the remedy’s impact.
Nasdaq closes Monday for Labor Day, according to its 2026 calendar. Alphabet’s next regular session begins Tuesday at 9:30 a.m. EDT. The court’s full opinion could follow around mid-September.
