Big Tech accounts for nearly two-thirds of the US digital ad market

Key stat: Big Tech (Amazon, Apple, Google, Meta, and Microsoft) will attract nearly two-thirds of US digital ad dollars this year, according to our October 2023 forecast. That’s more than double its share since we began tracking it in 2008.

Beyond the chart:

  • Big Tech’s dominance is largely thanks to strategic mergers and acquisitions. Big buys such as Facebook’s purchase of Instagram in 2012 and Google’s purchase of YouTube in 2006 have accelerated its power, but smaller, undeclared deals have added up too.
  • Google, Meta, and Amazon—and soon, Apple—are facing US antitrust lawsuits that could reshape the digital ad market and redistribute ad dollars.
