For instance, in June 2024, according to the Ericsson, a Sweden-based telecommunications company, the number of mobile subscriptions in the region is projected to increase from 1.2 billion in 2023 to 1.3 billion by 2029. Therefore, the growing number of smartphone users is driving the growth of the real time bidding (RTB) industry.

How Will The Drivers Impact Growth In The Global Real Time Bidding (RTB) Market?

• Growth In Digital Advertising Spending (High) – During the forecast period, the growth in digital advertising spending is expected to become a key growth driver for the real time bidding (RTB) market by 2030. Brands across industries are allocating larger portions of their marketing budgets to digital channels to improve audience reach, campaign efficiency, and measurable outcomes. The increasing shift from traditional media toward online advertising is generating higher demand for automated ad purchasing platforms capable of delivering targeted impressions at scale. Advertisers are also seeking greater transparency and performance tracking, further supporting the adoption of RTB technologies. • Rising Adoption Of Programmatic Advertising (High) – During the forecast period, the rising adoption of programmatic advertising is expected to emerge as a major factor driving the expansion of the real time bidding (RTB) market by 2030. Organizations are increasingly leveraging automated buying platforms to streamline campaign execution, optimize advertising budgets, and improve audience engagement. Programmatic technologies enable advertisers to access vast inventories across multiple channels while making data-driven bidding decisions in real time. The growing need for operational efficiency and personalized advertising experiences is accelerating the transition toward automated media transactions. • Increasing Internet Penetration And Connected Devices (Medium) – During the forecast period, the increasing internet penetration and connected devices is expected to act as a key growth catalyst for the real time bidding (RTB) market by 2030. Expanding access to high-speed internet and the growing number of smartphones, tablets, connected TVs, and other digital devices are creating more opportunities for advertisers to engage consumers across diverse touchpoints. The resulting increase in online activity generates larger volumes of advertising inventory and audience data, supporting more effective real-time bidding transactions. Additionally, multi-device consumer behavior is encouraging advertisers to invest in sophisticated advertising technologies capable of delivering consistent experiences across channels.

How Will The Restraints Impact Growth In The Global Real Time Bidding (RTB) Market?

• Concerns Over Data Privacy And Regulations (High) – During the forecast period, the concerns over data privacy and regulations act as a major restraint in the real-time bidding (RTB) market by limiting the extent to which advertisers can collect, process, and use consumer data for targeted advertising. Strict regulations such as GDPR and similar frameworks require companies to obtain explicit user consent, which reduces the availability of third-party data that fuels RTB systems. As RTB heavily depends on user data to deliver personalized ads and optimize bidding strategies, these restrictions can lower campaign effectiveness and return on investment. Additionally, compliance with evolving data protection laws increases operational costs and legal risks for market participants. Companies must invest in secure data management systems and legal expertise, which can be burdensome, especially for smaller firms. These regulatory pressures also discourage experimentation with new data-driven advertising models. As a result, advertisers may shift toward less data-intensive approaches, reducing demand for RTB platforms. Overall, heightened privacy concerns and regulatory scrutiny constrain growth by limiting data access and increasing compliance complexity. • Lack Of Transparency In Programmatic Ecosystem (High) – During the forecast period, the lack of transparency in the programmatic advertising ecosystem significantly restrains the RTB market by creating uncertainty and distrust among advertisers and publishers. RTB involves multiple intermediaries such as ad exchanges, demand-side platforms, and supply-side platforms, making it difficult for participants to clearly understand how ad inventory is priced and allocated. This opacity can lead to issues such as hidden fees, bid manipulation, and unclear reporting metrics, which reduce confidence in the system. Advertisers may question whether their budgets are being used efficiently or if they are reaching genuine audiences. Similarly, publishers may not receive fair value for their inventory due to unclear auction dynamics. The absence of transparency also makes it challenging to detect fraud, such as invalid traffic or bot-generated impressions. As trust diminishes, businesses may reduce their reliance on RTB platforms or seek alternative advertising methods with clearer accountability. This ultimately slows market adoption and growth. • High Implementation And Operational Complexity (Medium) – During the forecast period, the high implementation and operational complexity acts as a restraint in the RTB market by creating barriers to entry and limiting widespread adoption, particularly among small and medium-sized enterprises. Setting up RTB infrastructure requires advanced technical capabilities, including integration with demand-side platforms, data management platforms, and real-time analytics systems. Organizations must also manage large volumes of data and ensure low-latency processing to participate effectively in real-time auctions. This complexity increases the need for skilled personnel and continuous system maintenance, raising overall operational costs. Additionally, understanding and optimizing bidding strategies can be challenging, requiring expertise in data science and digital marketing. For many businesses, especially those with limited resources, these requirements can outweigh the perceived benefits of RTB. As a result, companies may hesitate to adopt or fully utilize RTB solutions. This slows market expansion and limits participation, thereby restraining overall growth.
