Which platform are Twitch deals facilitated through?

Twitch deals are facilitated through the Amazon DSP (Demand-Side Platform). Amazon DSP allows advertisers to programmatically buy video and display ads on Twitch, as well as on Amazon's owned and operated sites and across the web. It provides access to Amazon's exclusive audiences and measurement capabilities, making it the primary platform for managing and executing Twitch advertising campaigns. Amazon Marketplace Hub and Inventory Hub are not platforms for programmatic ad buying; they are related to seller services and inventory management within the broader Amazon ecosystem. While Twitch is the platform where the ads appear, the deals (i.e., the buying and selling of ad impressions) are managed through Amazon DSP.
