Premium CTV inventory is ad space sold through high-value channels — direct IO deals, programmatic guaranteed, or private marketplace (PMP) deals — where the publisher controls who buys and at what price. Premium inventory typically comes with strong audience data, brand-safe content contexts, and a direct relationship between publisher and advertiser. It commands significantly higher CPMs than remnant.
Remnant inventory is what remains after premium demand has been satisfied. It goes to the open programmatic exchange where any eligible buyer can bid — no guaranteed price, no committed buyer, and often limited audience signal in the bid request. In India's CTV market, where programmatic demand is thin and few DSPs actively bid on open exchange CTV inventory, remnant typically clears at substantially lower CPMs than premium inventory from the same publisher.
The gap between premium and remnant CPMs in India CTV is significant — industry estimates suggest premium direct-sold inventory achieves 3–5x the CPM of comparable open exchange remnant. This makes the strategic priority clear: publishers who want to improve yield should focus on moving inventory up the value chain — from open exchange remnant to PMP deals to direct IO — rather than optimising within each tier. The preconditions for that upgrade are audience data infrastructure, a sales narrative buyers find credible, and direct relationships with agencies or brands. Most India CTV publishers outside the top platforms are primarily trading remnant inventory through open exchange — the upside from building even one or two direct relationships is substantial.
