Google Faces DOJ Antitrust Appeal Over 90 Percent Search Market Dominance

Google holds roughly 90 percent of U.S. web search traffic, a share that the Department of Justice says gives the company monopoly power and harms competition. This dominance has drawn scrutiny from regulators and sparked debate over digital market fairness.

Department of Justice filed an antitrust lawsuit demanding that Google be split into separate entities for search, advertising and cloud services, arguing that the current structure stifles rivals and inflates ad prices. The lawsuit also cites exclusive device agreements that lock Google as default search.

Google appealed the DOJ's breakup request, contending that its integrated services improve user experience and that market share reflects consumer choice rather than illegal conduct, while urging the court to reject the forced division. The company says ad revenue funds free services.

Industry analysts warn that a court‑ordered split could reshape online advertising, create new competitors and trigger regulatory reviews worldwide, potentially lowering ad costs but also disrupting existing contracts and technology integrations. Analysts say Europe may follow, prompting global shifts.
