Magnite, Inc.: what insiders have been doing
Magnite, Inc. belongs to the Media & Communication sector. Filings by its managers are published through SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 140 filings came from 28 insiders.
The flow runs one way only: 43 sales worth €15.7M, from 11 insiders, and no purchase. The totals exclude 7 filings filed without an amount. Barrett Michael G. filed the largest sale, €5.8M, on 7 August 2026, which represents 0.19% of the company's market value.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
For context, the typical company on the same exchange (median of 5,458 companies) published 22 filings over the same period, against 140 filings here.

About Magnite, Inc.
Magnite, Inc. (ticker MGNI) is a U.S.-based company listed on the NASDAQ in the United States and operates in digital advertising technology with a strong focus on the sell-side of the market. Its core business is a technology platform that helps publishers, broadcasters, and media owners monetize advertising inventory programmatically across connected TV (CTV), video, display, audio, and mobile. In practical terms, Magnite sits on the supply side of the advertising ecosystem, connecting media owners with advertisers and agencies while helping optimize yield, improve workflow efficiency, and package premium inventory for programmatic demand. Its positioning is especially important in CTV, where advertising spend continues to migrate from linear TV to streaming environments. ([investor.magnite.com](https://investor.magnite.com/investor-overview?utm_source=openai))
The company’s roots go back to Rubicon Project, founded in 2007. Magnite in its current form was created after the April 1, 2020 merger of Rubicon Project and Telaria, which also led to the rebranding to Magnite and the ticker change to MGNI. Since then, the company has pursued a strategy of expansion through selective acquisitions and product integration. It acquired SpotX in 2021 to strengthen its video and CTV offering, and later acquired Carbon in 2022 to enhance publisher audience activation, identity, and first-party data capabilities. That evolution reflects a broader industry shift toward consolidated ad tech stacks that can support a more privacy-conscious, data-driven marketplace.

On the product side, Magnite’s key assets include SpringServe, its video and CTV ad server, and Magnite Streaming SSP, its supply-side platform for streaming inventory. In 2025, the company unveiled the next generation of SpringServe, combining ad serving and SSP functionality to simplify the path between buyers and sellers, and it also announced an evolution of ClearLine to unify curation and activation across its omnichannel footprint. These moves show a clear push toward more integrated, higher-efficiency tools, with increasing emphasis on AI-assisted workflows and tighter integration across the ad tech stack. ([investor.magnite.com](https://investor.magnite.com/news-releases/news-release-details/magnite-unveils-next-generation-springserve-combining-its?utm_source=openai))
Competitively, Magnite markets itself as the world’s largest independent sell-side advertising company, a claim that underscores one of its main differentiators versus vertically integrated competitors. Independence matters in ad tech because it can make publishers and media owners more comfortable partnering with a neutral platform rather than a competing media buyer. The company also emphasizes broad access to streaming supply and a global operating footprint, which supports relationships with major broadcasters, streaming platforms, and publishers across multiple geographies. ([investor.magnite.com](https://investor.magnite.com/news-releases/news-release-details/meet-magnite-largest-independent-omnichannel-sell-side-platform?utm_source=openai))
Recent developments have reinforced Magnite’s CTV-led growth narrative. In its fourth-quarter and full-year 2025 results, the company reported higher revenue, stronger contribution ex-TAC, and continued CTV momentum, while announcing a new $200 million share repurchase program. Magnite also highlighted new partnerships and product rollouts tied to CTV monetization, smart-TV gaming, and GenAI-powered ad creation, indicating that it remains focused on monetizing the rapid evolution of streaming TV and premium digital video.
