Two major antitrust lawsuits have been making headlines against tech giant Google, alleging that its dominance in search and advertising has led to manipulation of the market at the expense of competitors and consumers. The cases echo those brought against Microsoft in the early 2000s, where regulators sought to break up the company’s monopoly.

One case focused on Google’s search business kicked off in mid-September 2023, with US District Judge Amit Mehta presiding over proceedings that concluded in May 2024. The remedy phase of this trial ended in September 2025, with Judge Mehta imposing data-sharing requirements rather than forcing a breakup.

The second case targeted Google’s advertising practices and took place over 15 days in September 2024. US District Judge Leonie Brinkema ruled against the company in April 2025, finding that it had engaged in exclusionary conduct that harmed competitors, publishers, and ultimately consumers of information on the open web.

The Search for Balance: Google’s Dominance Challenged

At stake is whether Google will be forced to divest its Chrome browser and Android operating system as part of sweeping remedies aimed at curbing its monopoly in online search. In a significant win for Google, Judge Mehta ruled that the tech giant does not have to give up these businesses, but instead must share data with rivals.

The remedy phase of this trial began on April 21, 2025, with federal prosecutors warning that Google might leverage artificial intelligence to extend its market control into new areas. They demanded “strong measures” to prevent the company from entrenching its search monopoly further.

Google’s Advertising Monopoly Under Fire

The second case focused on advertising practices has also led to significant wins for regulators. In April 2025, Judge Brinkema ruled that Google had illegally monopolized the ad tech market. The ruling noted that this conduct “substantially harmed” publisher customers and the competitive process.

Remedies in this case are still pending but could include breaking up Google’s advertising products or imposing changes to its business practices. This would be a significant blow for Google, which has long dominated online search and advertising markets.

The Road Ahead: Implications of These Rulings

While the outcome is far from certain, these antitrust battles have already sent shockwaves through Silicon Valley. Regulators are pushing back against tech giants’ dominance in key areas like search and advertising.

If Google’s competitors were able to access data on how it ranks websites or generates ad revenue, this could significantly level the playing field and allow them to better compete with the tech giant. This shift would be a significant change for consumers who rely on online information services every day.

As regulators continue their push against monopoly power in tech, one thing is clear: Google’s dominance will face increasing scrutiny from antitrust enforcers as they seek to protect competition and consumer interests.
