Magnite (MGNI) Rosenblatt's 6th Annual Technology Summit: The Age of AI (Part II) summary

Antitrust and market structure

• Antitrust remedies could drive significant incremental earnings, with potential for $50 million EBITDA lift per 1% share shift from Google to Magnite, as behavioral remedies may be implemented quickly and impact market share.

• Google was found guilty of monopolistic practices in ad serving and exchange, leveraging its ad server dominance to restrict competition and maintain a 60% market share, disadvantaging publishers and other SSPs.

• Remedies such as implementing Prebid, an open-source solution, could level the playing field by ensuring equal access and transparency in auctions, potentially redistributing up to 30-50% of Google's share.

• The open web remains a sizable market despite declining traffic, and a guilty verdict is expected to result in actionable remedies, with a low probability of inaction.

• Behavioral remedies could be implemented rapidly, possibly within a week, and are not expected to be delayed by appeals, with Prebid.org positioned as a potential industry watchdog.

CTV and programmatic growth

• CTV is now over half of the business mix, with contribution ex-TAC up 36% year-over-year in Q2, outpacing overall CTV ad spend growth due to strong programmatic positioning.

• Magnite's programmatic share in CTV is estimated at 20-25%, with exclusive access to major inventories like Roku, Disney, and Netflix, and a leading position in programmatic ad serving.

• The SpringServe platform integrates ad serving and SSP functions, resulting in high customer stickiness and nearly universal adoption among clients.

• Agency marketplaces powered by Magnite are gaining scale, allowing agencies to reclaim influence from DSPs and provide greater transparency and data control.

• Walmart's acquisition of Vizio and DSP Vibe.co expands Magnite's footprint, with future growth expected as Walmart opens its data to multiple DSPs and integrates with Magnite.

Technology and innovation

• Magnite Orchestration and agentic workflows aim to convert traditional insertion order spend into programmatic transactions, compressing campaign setup from weeks to minutes and expanding the addressable market by 20-25%.

• The orchestration platform is agnostic, allowing integration of external or internal agents, optimizing workflows across buyers and publishers in real time.

• AI-driven agentic solutions are expected to improve velocity and reduce friction in the marketplace.
