Magnite

Largest independent omnichannel SSP globally, with a leading position in CTV/streaming advertising

Magnite is the leading independent omnichannel sell-side platform (SSP) in the digital advertising ecosystem, formed through the merger of Rubicon Project and Telaria in 2020. The company subsequently expanded its capabilities through the acquisitions of SpotX (2021) and SpringServe (2021), significantly strengthening its position in the fast-growing Connected TV (CTV) and streaming video advertising markets. Magnite provides publishers, broadcasters, and streaming services with the technology to manage, sell, and optimize their advertising inventory across CTV, desktop, mobile, and audio formats. Magnite's platform enables publishers to access demand from a wide range of buyers, including programmatic advertisers, direct deals, and private marketplaces. Its suite of tools covers ad serving, yield optimization, audience targeting, and real-time bidding infrastructure. The company serves some of the world's largest media companies, broadcasters, and digital publishers, positioning itself as a critical infrastructure layer between content owners and advertisers. As an independent SSP — not owned by a major buy-side platform, agency holding company, or walled garden — Magnite differentiates itself by offering publishers a neutral, conflict-free technology partner. The company is publicly traded on NASDAQ and competes with Google's Ad Manager, PubMatic, and other SSPs, while also facing competition from demand-side platforms expanding into supply-side services. Magnite's scale, CTV specialization, and independence make it a significant force in the evolving programmatic advertising landscape.
