Overview

ACCE thesis

Magnite operates the largest independent sell-side advertising platform, connecting publishers with advertisers through programmatic auctions across display, video, audio, and connected TV inventory. The company benefits from the structural shift of advertising dollars from linear TV to streaming platforms, where programmatic buying dominates and Magnite commands meaningful market share. Connected TV revenue jumped 25% year-over-year in Q3 2024, now representing over 60% of total revenue as streaming viewership continues displacing traditional television. The stock trades at just 11x forward earnings despite growing revenue at 6% annually in a fragmented market ripe for consolidation. Management expects CTV growth to accelerate through 2025 as more advertisers shift budgets to programmatic channels where Magnite's scale advantage widens the competitive moat.
