Magnite

Magnite operates as a sell-side advertising technology provider, offering publishers and media owners a unified platform to manage and monetize ad inventory across streaming and open-web environments. Its value proposition centers on yield optimization, unified ad serving and SSP workflows (especially in CTV/OTT), and tools for both publishers and buyers to structure curated marketplaces and private deals. The business is fundamentally infrastructure for the programmatic supply side, consolidating multiple acquired technologies into a single ecosystem serving large media owners, broadcasters, and digital publishers globally.

Magnite, Inc. is a US-based, publicly traded advertising technology company that operates a global sell-side platform for digital media owners. It provides publishers, broadcasters, and streaming app operators with tools to manage, package, and sell advertising inventory across CTV/OTT, online video, display, audio, native, and DOOH channels, consolidating capabilities from assets such as Rubicon Project, Telaria, SpotX, and SpringServe. The company generates revenue primarily by taking a percentage fee on programmatic media transactions processed through its SSP and by offering related ad serving and marketplace tools. Its core customers are publishers and media owners on the supply side, with additional products enabling agencies and buyers to curate supply, but not acting as a demand-side platform itself.
