Magnite, Inc. MGNI

Company Overview

Magnite, Inc. is an independent advertising technology company operating in the digital advertising and media infrastructure industry. The company provides a supply-side platform (SSP) that enables publishers to monetize their digital advertising inventory across multiple channels, including connected television, online video, mobile, and desktop display. Magnite primarily generates revenue by facilitating automated advertising transactions between publishers and advertisers, earning fees based on media spend transacted through its platform.

The company is positioned as the largest independent SSP, emphasizing neutrality and transparency in an ecosystem increasingly dominated by vertically integrated platforms. Magnite’s scale, particularly in connected television (CTV), is a key strategic advantage, allowing it to serve large media owners seeking alternatives to walled-garden platforms. The company was formed in 2020 through the merger of Rubicon Project and Telaria, combining strong capabilities in programmatic advertising and CTV. Its evolution continued with the acquisition of SpotX in 2021, significantly expanding its CTV footprint and relationships with major broadcasters and streaming platforms.
