Alphabet’s Google, Meta, Apple, Amazon, Microsoft, and Nvidia are all under scrutiny as U.S. regulators step up efforts to curb the dominance of Big Tech. A recent court ruling against Google, ordering the company to share search data with competitors, highlights the scale of the legal challenges facing the world’s most valuable technology companies.

Below is the current status of the major antitrust cases and investigations:

GOOGLE

  • A Washington judge ruled that Google must share search data with competitors and stop striking exclusive deals that block rival services from being preinstalled on devices.
  • The company will not be forced to sell its Chrome browser or Android operating system.
  • Google has appealed, with the process expected to take years, but has already eased some of its contracts with device makers. Apple, meanwhile, has hinted at adding AI-driven search alternatives.
  • Separately, Google faces a September trial in Virginia to determine whether it must divest parts of its advertising technology business, where regulators allege it holds two illegal monopolies.

META (Facebook, Instagram, WhatsApp)

  • The FTC is seeking to unwind Meta’s acquisitions of Instagram and WhatsApp, arguing that the purchases were meant to eliminate future competition.
  • Meta says the government’s case relies on an artificially narrow definition of social media that ignores rivals like TikTok and YouTube.
  • A Washington judge is not expected to issue a ruling before late 2025.

AMAZON

  • The FTC and several states are suing Amazon in Seattle, accusing the company of using algorithms to inflate prices by over $1 billion for U.S. households and employing anti-competitive tactics to maintain its dominance.
  • Amazon says it abandoned the disputed pricing algorithm in 2019.
  • A judge rejected much of Amazon’s attempt to dismiss the case, and trial is scheduled for February 2027.

APPLE

  • The Justice Department and state attorneys general allege Apple restricts third-party apps and devices—such as digital wallets, messaging apps, and smartwatches—to lock consumers into its iPhone ecosystem.
  • Apple’s motion to dismiss was denied in June.
  • Both sides are exchanging documents, with deadlines stretching into early 2027. No trial date has been set.

MICROSOFT

  • The FTC opened a 2024 probe into whether Microsoft unfairly used licensing terms in its productivity software to discourage customers from moving data to competing platforms.
  • No case has yet been filed.

NVIDIA

  • The Justice Department has launched an investigation into whether the chipmaker, now worth more than $4 trillion, has engaged in anti-competitive practices in the booming artificial intelligence sector.
  • No lawsuit has been filed so far.

These cases reflect the most sweeping wave of U.S. antitrust scrutiny in decades. While many of the lawsuits may take years to resolve, analysts say the pressure alone is already pushing Big Tech to adjust business practices in anticipation of stricter regulation.
