A curated marketplace product from Index Exchange, a top-tier independent SSP, targeting premium programmatic trading between publishers and brand advertisers
Index Marketplaces is a product offering from Index Exchange (IX), one of the leading independent programmatic advertising exchanges. Launched in 2024, Index Marketplaces represents IX's move into curated marketplace solutions, allowing buyers and sellers to create tailored, high-quality programmatic trading environments with greater transparency, control, and brand safety than open auction environments typically provide. The product enables media buyers to access premium publisher inventory through curated deals, leveraging Index Exchange's extensive publisher relationships and supply-side infrastructure. Curated marketplaces allow buyers to define specific audience, contextual, and quality parameters, while publishers benefit from higher-value demand and more predictable revenue streams. This positions IX competitively against other SSPs and marketplace operators like Magnite, PubMatic, and OpenX that have launched similar curation capabilities. Index Marketplaces fits into the broader industry trend toward supply path optimization (SPO) and curation, where advertisers seek fewer, more trusted supply paths to premium inventory. By offering curation natively within its exchange infrastructure, Index Exchange strengthens its value proposition to both the buy and sell sides, differentiating itself in an increasingly competitive SSP landscape where transparency and quality signals are paramount.
