Magnite is one of the largest supply-side platform providers, or SSP, in online advertising. The firm was previously named The Rubicon Project (an online ad exchange) and became Magnite after merging with Telaria (an SSP focused mainly on streaming video providers) in 2020. The firm also purchased another of the leading SSPs within the CTV market, SpotX, in 2021 for $1.2 billion, cementing its long-term focus on grabbing market share in this area. The firm generates nearly 45% of its revenue from the programmatic sale of CTV ad inventory, 35% from mobile online sites and apps, and the remaining from websites accessed via computer.
