DOJ and 11 state AGs, all Republican, file a suit alleging that Google engaged in anticompetitive conduct to preserve monopolies in search, search-advertising
Lawsuit follows lengthy investigation and seeks to break company's grip over search traffic — The Justice Department filed …
Context & Ripple Effects
This filing is the endpoint of a year-long build-up: reports in May 2020 flagged the DOJ and state AGs converging on Google's search dominance and ad business as the probe neared a lawsuit, and September reporting showed about a dozen mostly-GOP-led states weighing whether to join or file separately before the complaint landed. Eleven Republican AGs signed on with the Justice Department — a rare bipartisan-adjacent coalition against a single platform.
The suit is also the opening move in what became a multi-front campaign: weeks later, a bipartisan group of 38 AGs filed its own search antitrust suit, naming exclusionary contracts with Apple, and by 2023 additional states had joined the DOJ case as it expanded into ad tech. Today's complaint defines the legal theory — preserving monopoly through distribution deals — that the later cases build on.
First-order effects
- Google now defends its search and search-advertising monopolies in federal court, with the complaint targeting the conduct it used to preserve that grip — the default-placement deals that lock in search traffic.
Second-order effects
- State AGs split into parallel tracks rather than consolidating: a separate bipartisan 38-state suit follows within weeks, adding Apple's exclusionary contracts to the target list and multiplying settlement pressure on Google.
Third-order effects
- If the distribution-deal theory holds, the structural remedy reaches beyond Google to the default-agreements ecosystem — device makers and browser operators paid for placement — and the case template extends to ad tech, as the 2023 state additions to the DOJ suit show.
The trend: US antitrust enforcement against Big Tech is shifting from investigation to sustained multi-front litigation, with state AGs operating as a parallel enforcement layer alongside the DOJ.
