North AmericaMarket Growth Drivers and Industry Trends
As advertisers shift budget toward audience-level targeting rather than broad digital reach, the real-time bidding market is benefiting from the ability to evaluate individual impressions and bid selectively based on user attributes, context, and expected conversion value. This changes buying behavior in practice: brands and agencies increasingly favor platforms that can connect first-party data, audience segmentation, and instant decisioning, because wasted impressions become harder to justify under tighter performance expectations. The result is stronger platform adoption among buyers seeking more accountable media spend, while publishers also align with real-time bidding infrastructure to capture higher value from inventory that can be matched to specific advertiser objectives.
AI-driven programmatic advertising optimization improving campaign efficiency and advertiser return on investment
AI-based optimization is strengthening the real-time bidding market by making bidding decisions faster and more adaptive to performance signals that change continuously during a campaign. In practical terms, machine learning models help advertisers refine bid prices, audience selection, creative delivery, and placement choices based on likelihood of engagement or conversion, which improves spend allocation without requiring constant manual intervention. That operational advantage is influencing market adoption as agencies and brands look for programmatic systems that can translate large volumes of auction data into better campaign outcomes, reinforcing demand for more sophisticated real-time bidding platforms and analytics capabilities.
Expanding connected TV and digital out-of-home advertising creating new programmatic inventory opportunities
The expansion of connected TV and digital out-of-home is broadening the addressable supply base for the real-time bidding market by bringing premium, screen-based inventory into automated trading environments that were once dominated by display and mobile formats. This matters because advertisers want coordinated campaigns across channels with centralized buying, targeting, and measurement, and real-time bidding infrastructure allows these emerging formats to be purchased with greater flexibility than traditional direct sales models. As media owners open more inventory to programmatic transactions, the real-time bidding market gains from rising impression volume, a more diverse mix of ad placements, and stronger interest from buyers seeking unified omnichannel execution.

Real-time Bidding Market Share (%), Auction Type, 2025
Go beyond the chart, access full insights & data tables
Request Free Sample ReportOpen Auction held a 36.04% share of the real-time bidding market in 2025, reflecting its broad liquidity and ease of access for advertisers seeking scalable impression buying across diverse publishers. Its leadership is maintained through the practical advantage of allowing buyers to participate in high-volume auctions without the setup complexity of more curated transaction models. For many campaign types, especially those focused on reach and flexible budget deployment, Open Auction remains the most efficient mechanism in the real-time bidding market.
Preferred Deals are emerging as the fastest-growing auction type in the real-time bidding market because buyers increasingly want greater control over inventory quality and pricing certainty without fully moving into rigid direct-buy structures. This model is seeing wider adoption as advertisers look to secure access to selected audiences and publisher environments before inventory enters broader auction pools. Compared with Open Auction and other alternatives, Preferred Deals better align with the market’s growing emphasis on brand suitability, supply path discipline, and more predictable media execution.
Device Segment Analysis: Mobile (Largest & Fastest-Growing Segment)
By 2025, Mobile accounted for the largest share of the real-time bidding market and continued to post the strongest growth momentum, reinforced through the central role of smartphones in daily digital consumption. Its leadership is rooted in the sheer volume of mobile web and app traffic, which creates a constant flow of bid opportunities across formats and user contexts. Growth remains strong because advertisers are directing more programmatic spend toward environments where users spend the most time and where real-time, context-aware engagement is easier to activate. In the real-time bidding market, Mobile benefits from this combination of scale, frequency of use, and execution flexibility, which supports both its current dominance and continued expansion.
