Real-time Bidding (RTB) Market Overview

The global real-time bidding (RTB) market size was valued at approximately USD 13.82 billion in 2024 and is expected to reach USD 43.29 billion by 2033, growing at a compound annual growth rate (CAGR) of about 13.2% from 2025 to 2033.

Real-time Bidding (RTB) is a type of programmatic trading in which available ad inventory on publisher websites is auctioned off to advertisers virtually quickly. Real-time bidding enables buyers and sellers to exchange digital media more effectively by allowing online audiences from a variety of sources, including those acquired anonymously via cookies, to be used. In an open auction, purchasers place real-time bids for available ad inventory. Based on their own standards, such as the highest price or the largest revenue share, the seller chooses the successful bidder. In this strategy, the advertiser will bid against rivals and triumph by putting in the highest bids to obtain impressions from the target audience that satisfy the advertiser's campaign objectives. An invited auction is one in which a publisher solicits the participation of an ad exchange so that they can engage in competitive bidding to fill the publisher's available inventory. When publishers permit access to all demand sources without limiting the number of bidders or the range of bid prices, an open auction occurs.

The rising popularity of real-time bidding (RTB) advertising across multiple industries is a primary driver of this expansion. Factors such as publisher competition and advertisers' desire for transparency and ad efficacy are also driving the growth of this market over the forecast period.
