The Department of Justice (DOJ) and plaintiff states sued Google in the U.S. District Court for the District of Columbia, alleging it illegally maintained its search monopoly through default agreements. The court held Google liable in 2024 and entered a six-year final judgment on remedies in December 2025. Both sides have appealed to the D.C. Circuit, and a joint request to hold oral argument as early as December 9, 2026, is pending.
Latest development Oct 19, 2026
On October 19, 2026, Google filed a further brief at the D.C. Circuit continuing to challenge Judge Mehta’s liability and remedies rulings. It argues that the government’s case penalizes lawfully earned market dominance. A joint request by Google and the Department of Justice (DOJ) to prioritize the cross-appeals and hold oral argument as early as December 9, 2026, remains pending.
Why it matters
The appeal will decide how Section 2 of the Sherman Act applies to search distribution defaults, data access, and payments to distributors. The outcome affects Google, Apple, Mozilla, and AI search entrants.
Background
In October 2020, the U.S. Department of Justice (DOJ) and plaintiff states sued Google LLC in the U.S. District Court for the District of Columbia. They alleged that Google illegally maintained its search monopoly through multibillion-dollar default agreements. Those agreements made Google the out-of-the-box search engine on Apple devices, Android, and major browsers. The liability trial began in September 2023. Parallel cases over Google’s ad-tech business are proceeding separately.
In August 2024, Judge Amit P. Mehta ruled that Google is a monopolist in general search. The court held that Google violated Section 2 of the Sherman Act in the markets for general search services and general search text ads, chiefly through its exclusive default agreements. A remedies trial opened in April 2025. The plaintiffs sought divestiture of Chrome, data-sharing mandates, and an end to default payments, while Google proposed narrower limits on exclusivity.
On September 2, 2025, the court issued its remedies decision. It barred exclusive default contracts for Search, Chrome, and Google’s AI products, and ordered Google to share search-index and user-interaction data and offer syndication to qualified competitors. It let Google keep paying for non-exclusive defaults and refused to order divestiture of Chrome or Android. The rise of generative AI search figured heavily in the court’s reasoning. On December 5, 2025, the court entered a six-year final judgment that implements the remedies decision and establishes a Technical Committee to oversee compliance.
Google appealed the liability and remedies rulings to the U.S. Court of Appeals for the District of Columbia Circuit on January 16, 2026. The DOJ and plaintiff states cross-appealed on February 3, 2026, seeking stronger remedies, including a ban on Google’s payments to distributors such as Apple. On May 7, 2026, the district court denied Google’s motion for a partial stay without prejudice, so implementation is proceeding. Briefing ran from Google’s opening brief on May 22, 2026, through the government’s response and cross-appeal brief on July 28, 2026, to Google’s reply on September 29, 2026. On October 5, 2026, the DOJ and Google jointly sought priority scheduling and argument as early as December 9, 2026, and Google filed a further brief on October 19.

Experimental AI forecast
How it is madeHow will the D.C. Circuit rule on the cross-appeals in United States v. Google (Nos. 26-5023, 26-5047, 26-5049) by March 31, 2028?
- D.C. Circuit affirms in full38%
- Liability upheld, remedies changed36%
- Still pending on March 31, 202812%
- D.C. Circuit reverses liability9%
- Google and DOJ settle appeals5%
- Resolves by
- Mar 31, 2028in 17 months
- Record confidence
- Medium
The D.C. Circuit is most likely to uphold Google’s liability, either affirming in full (38%) or modifying the remedies (36%), by March 31, 2028. Fact-bound liability findings after a long bench trial get deferential review, while novel data-sharing remedies and the cross-appeal give the court more room to adjust relief.
How it resolves. Resolves on the D.C. Circuit’s panel judgment or opinion issued on or before March 31, 2028. “Affirms in full” means liability and the December 5, 2025, final judgment both stand unchanged. “Liability upheld, remedies changed” means the Section 2 liability finding stands in whole or in part but any remedy provision is vacated, modified, or remanded, including relief granted on the government’s cross-appeal. “Reverses liability” means the court vacates or reverses the liability holding in full. “Settle” means the parties file a settlement or joint dismissal of the appeals before a merits ruling. If no merits ruling or settlement has occurred by March 31, 2028, the outcome is still pending. Later rehearing or certiorari does not change resolution.
Reasoning
Starting point. Federal courts of appeals reviewing civil judgments after bench trials, with Section 2 monopolization appeals such as United States v. Microsoft (D.C. Cir. 2001) as the closest comparator: Federal courts of appeals reverse roughly 10% to 15% of civil judgments. In complex Section 2 cases, partial affirmance with remedy changes is common, as in Microsoft.
Courts of appeals reverse about 10% to 15% of civil judgments, and findings from a lengthy bench trial are reviewed for clear error. Google’s best liability arguments are legal ones about market definition and exclusionary conduct, which keeps full reversal possible but unlikely at 9%. Remedies are reviewed for abuse of discretion, but the data-sharing and syndication mandates are novel. In Microsoft, the D.C. Circuit upheld core liability yet vacated the remedy, so a mixed result is a strong alternative at 36%. The government’s cross-appeal on distributor payments also creates a path to modified relief. Briefing is complete and both sides seek argument as early as December 9, 2026, so a ruling well before March 2028 is likely. Settlement stays low because the government has prevailed at trial and Google is contesting liability itself. Since the October 7, 2026, forecast, the record shows only Google’s further brief of October 19 and no ruling on the scheduling request, so no outcome moved by five points or more.

What it would mean
If the D.C. Circuit affirms in full, no money changes hands. But the six-year judgment would keep governing Google’s search business, which earned about $220B in 2025. Google could keep paying Apple, Mozilla, and others for non-exclusive defaults, so Apple’s roughly $20B a year from Google would survive. The real cost would be sharing search-index and user-interaction data, plus syndication to qualified competitors. No public estimate of that cost exists. Alphabet holds about $270B in cash and short-term securities, so compliance is an operating burden, not a solvency question.
The outcome with the largest consequences is a mixed ruling that grants the government’s cross-appeal and opens the door to banning Google’s payments to distributors. Apple would then risk about $13B to $20B a year in high-margin revenue. Mozilla would risk about $510M, roughly 85% of its income. By a 2020 Google analysis, losing the Apple default could cost Google about $28B to $33B in revenue. A ban would not take effect at once. It would need a remand, new remedy proceedings, and likely further appeals.
Money, who pays, markets and what to watch
Two steps ahead. If a payment ban ever followed, Google would stop paying Apple about $20B a year. By its own 2020 estimate, it would risk about $28B to $33B in revenue. Its net exposure could be far smaller than the headline figure. Apple and Mozilla, which are not parties, would absorb the surest loss. That gives them strong reasons to be heard on any remand, and it gives Google room to settle.
The money
- Alphabet: $224.5B a year of revenue at stake. Google Search & other revenue for fiscal 2025 ($224,532M). This is the business line that the six-year final judgment governs through the exclusivity ban, data sharing, and syndication. It shows what the remedy touches, not a loss estimate. Ongoing. Contract restrictions are already in force and the stay was denied. Data access starts after 45 days’ notice. The judgment runs six years from December 5, 2025.[1] That is 56% of its annual revenue ($402.8B, Dec 31, 2025).
- Alphabet: $28.2B to $32.7B a year of revenue at stake. A 2020 internal Google analysis estimated $28.2B to $32.7B in lost revenue if Google were not the default search engine on Apple devices. This is the annual revenue a distributor-payment ban could put at stake if the cross-appeal succeeded. Only if the D.C. Circuit vacates the refusal to ban payments and a remand orders a ban. Realistically 2028 or later, after further proceedings and any Supreme Court review.[2] That is 7% to 8.1% of its annual revenue ($402.8B, Dec 31, 2025).
- Apple: $12.5B to $20B a year of revenue at stake. The low figure is JPMorgan’s estimate of Apple’s revenue at risk if Google’s default payments change ($12.5B). The high figure is Google’s reported 2022 payment to Apple for Safari default status ($20B). Only after a successful cross-appeal, a remand, and a new payment ban. Under affirmance or reversal, the payments may continue on non-exclusive terms.[3][4]
- Mozilla: $510M a year of revenue at stake. Google search payments to Mozilla in the 2021–2022 financial statements ($510M of $593M in revenue). This is the royalty stream a distributor-payment ban would put at stake. Only if a payment ban follows a successful cross-appeal and remand.[5] That is 86% of its annual revenue ($593M, 2022).
- Figures used: Alphabet, market value $3.4T (Nov 3, 2026)[6] · Alphabet, cash $265.1B (Sep 30, 2026)[7] · Alphabet, annual revenue $402.8B (Dec 31, 2025)[8] · Mozilla, annual revenue $593M (2022)[5]
Who pays
- No damages are at issue, so the case has no insurer, indemnity, or funder angle. Alphabet bears the cost of complying with the exclusivity ban, data sharing, and syndication, under a Technical Committee, for six years.
- If a payment ban followed the cross-appeal, Apple and Mozilla would bear the surest loss even though they are not parties. Bank of America put Google’s payments at about 20% of Apple’s Services revenue.[4][5]
- Mozilla’s audited 2024 statements attribute about 86% of customer revenue to one customer. Its CFO testified that Google provides roughly 85% of Mozilla’s revenue.[9]
- If the D.C. Circuit reverses liability (9%), the remedies would fall away. Google would no longer owe data sharing or syndication, and it could again seek exclusive default deals.
Markets
- Alphabet’s GOOGL and GOOG shares trade on Nasdaq, with a market value of $3.44T as of November 3, 2026.[6]
- Alphabet shares rose on September 3, 2025, after the remedies decision spared Chrome. Reports of the size differ, from about 6% to about 8%.[10][11]
- Apple shares also rose on September 3, 2025. Reports range from about 3% to 3.2%. Analysts called Apple a winner because Google could keep paying for non-exclusive defaults.[10][11][4]
- Alphabet’s bondholders are also exposed. Alphabet issued senior unsecured notes for net proceeds of $28.7B in the third quarter of 2026 and $20.3B in the second quarter.[7][12]
Collecting
- There is no money judgment to collect. The government enforces the final judgment through the Technical Committee and, if needed, contempt proceedings in the district court.
- Implementation is proceeding because the court denied a partial stay on May 7, 2026. Plaintiffs must give 45 days’ notice before any qualified competitor first gets data or syndication access, and Google can then renew its stay request.
- Contract restrictions took effect on February 3, 2026. The data and syndication systems were still being built as of mid-2026.[13]
Beyond the parties
- An affirmance would set D.C. Circuit precedent on when exclusive distribution defaults violate Section 2 of the Sherman Act. That would bind future cases in the circuit and persuade courts elsewhere.
- The exclusivity ban covers Google’s AI products as well as Search and Chrome. Default deals for AI assistants with device makers and carriers would need to stay non-exclusive.[4]
- Data sharing and syndication would create a supply channel for qualified rival search and AI entrants. Morgan Stanley warned that this could reduce Google’s payments to Apple over time.[4]
- A payment ban could threaten Firefox’s funding. Mozilla has warned that limits on Google’s default payments could endanger the browser’s survival.[9]
What to watch
- Late 2026D.C. Circuit rules on the joint DOJ and Google request for priority scheduling[14]
- Dec 9, 2026Earliest proposed date for oral argument on the cross-appeals
- Before first data accessPlaintiffs give 45 days’ notice before a qualified competitor gets data or syndication access, which opens a renewed stay request
