Magnite Q3 revenue beats, driven by political ad spends

What happened

Magnite said third-quarter revenue rose 14% year over year and beat analyst expectations. Adjusted earnings per share and adjusted EBITDA also beat expectations. The company attributed results partly to 39% growth in connected-TV contribution excluding traffic acquisition costs, while political advertising, mostly in connected TV, exceeded expectations.

Confirmed

Global impact / market context

The results point to stronger advertising activity flowing through Magnite’s connected-TV business, which can lift revenue and earnings when ad placements grow. Political advertising added an unexpected boost, but the company’s forecast also indicates growth beyond that source, reducing reliance on one temporary demand driver.

Analyst inference

Magnite raised its 2026 growth outlook for contribution excluding traffic acquisition costs to about 17%, from 13%–14%, and expects 2027 top-line growth above 15% without political ads. These forecasts suggest management sees broader demand supporting revenue after the political-ad boost fades.

Confirmed

What to watch

1. Watch whether connected-TV contribution excluding traffic acquisition costs keeps growing; its reported 39% rise was a key driver, so a slowdown could weaken revenue growth. Analyst inference
2. Compare fourth-quarter contribution excluding traffic acquisition costs with the company’s forecast range, which will show whether its expected business growth is tracking as planned. Confirmed
3. Assess whether political advertising remains near three times its initial forecast; a pullback could slow revenue growth if other advertising demand does not make up the difference. Analyst inference
