An ad exchange is a digital marketplace where advertisers buy and sell ad inventory in real-time auctions, enabling programmatic ad buying across multiple publishers. A spendcap is a budget control mechanism set by advertisers or demand-side platforms (DSPs) to limit the total amount of money spent on ad campaigns or within specific channels, including ad exchanges. The relationship between the two is practical and operational: when advertisers participate in ad exchanges, they often implement spendcaps to control their financial exposure and pacing across multiple bids and impressions. Without spendcaps, advertisers risk overspending due to the dynamic, real-time nature of ad exchanges where bids can rapidly accumulate costs. Conversely, spendcaps rely on the transactional environment of ad exchanges to enforce budget limits effectively in programmatic buying. Thus, spendcaps act as a financial safeguard that directly governs how much budget is allocated and spent within ad exchanges, ensuring campaign cost efficiency and preventing budget overruns during real-time bidding processes.
