Magnite, Inc. MGNI

MGNI Company Overview

Magnite, Inc. is an independent sell-side advertising technology company that provides programmatic advertising solutions for publishers and media owners. The company operates primarily in the digital advertising and connected television (CTV) industries, helping publishers monetize advertising inventory across channels including CTV, online video, display, audio, and mobile. Magnite’s platform enables automated buying and selling of digital advertising inventory through real-time auctions and programmatic marketplaces.

The company’s principal revenue drivers are advertising transaction fees generated through its programmatic advertising platform, with CTV representing a significant and growing portion of revenue according to recent public filings and earnings disclosures. Magnite serves publishers, broadcasters, streaming platforms, app developers, and media companies globally. Its strategic positioning is tied to its status as one of the largest independent supply-side platforms (SSPs), offering an alternative to vertically integrated advertising ecosystems operated by large technology companies. Magnite was formed through the 2020 merger of Rubicon Project and Telaria, combining display and CTV advertising capabilities into a unified platform.
