Updated on Nov. 5, 2026 in Advertising

Magnite reported third-quarter 2026 total contribution ex-TAC of $201 million, beating expectations by more than $10 million on its November 4, 2026 earnings call. The company also raised its full-year 2026 outlook across the board.
Why it matters
Connected television now makes up 53% of Magnite's business excluding traffic acquisition costs, signaling the growing weight of streaming advertising in the ad-tech sector. Cost controls and streaming growth widened margins at the same time.
Magnite reported $201 million in third-quarter total contribution ex-TAC, beating expectations by over $10 million, with operating expenses steady at $154 million and an adjusted EBITDA margin of 42%. Political advertising reached $12 million in the quarter, and the company did not disclose the full-year revised dollar outlook.
The players
Magnite
Magnite is a sell-side advertising technology company that operates an open marketplace connecting publishers and advertisers, with a significant presence in connected television advertising.
ClearLine
ClearLine is Magnite's direct-buying tool that connects advertisers directly to streaming publishers, bypassing intermediary steps in the ad buying process.
The details
Magnite credited streaming ad growth and cost reductions for the quarter, including moving data processing from the cloud to in-house servers and cutting its cost per billion streaming ad requests by over 50% year over year. About 20% of third-quarter political demand flowed through ClearLine, the company's direct-buying tool connecting advertisers to streaming publishers.
Timeline
Nov. 4, 2026: Magnite held its third-quarter 2026 earnings call.
2026: Full-year political contribution ex-TAC is expected to exceed $40 million.
2027: The outlook calls for growth above 15% excluding political, or more than 10% as reported.
Market Landscape
Connected television's rise from a niche channel to over half of Magnite's business reflects the broader migration of TV advertising budgets from linear broadcast to streaming platforms. The company's projected 25% long-term connected TV growth over three to five years places it at the center of that shift.
Streaming ad growth and political advertising demand are shaping where advertisers spend, which can influence the ads viewers see on connected TV services. Advertisers using direct-buying tools like ClearLine gain a more direct path to streaming publishers.
The takeaway
Watch how connected television keeps gaining share of ad budgets, since that trend determines where advertising dollars flow next. Advertisers should review direct-buying options as streaming inventory grows.
