Global programmatic digital out of home advertising has crossed the $1 billion mark, with spending reaching an estimated $1.339 billion in 2025 as advertisers increasingly turn to automated technology to buy and activate outdoor media.

However, the World Out of Home Organization disclosed this in its inaugural WOO Global pDOOH Expenditure Study 2026, which puts programmatic transactions at 7.0 percent of the worldwide digital out of home advertising market.

Meanwhile,the study, independently aggregated by PricewaterhouseCoopers LLP, PwC, draws revenue submissions from 12 supply side platforms across more than 40 markets spanning the Americas, Europe, the Middle East and Africa, and Asia Pacific. WOO said the research provides the first supply side measurement of global pDOOH expenditure at this scale.

Again, for the industry, the significance extends beyond the $1.339 billion headline figure. The findings reveal sharp differences between market size and programmatic adoption, while also pointing to substantial room for expansion in regions where digital out of home has already established a sizeable advertising base.

Moreso, Charles Parry Okeden, Vice President and Global Lead, Audience Measurement and Data at WOO, said the research gives the sector a common benchmark for understanding the development of programmatic out of home advertising.

Imperatively,he noted that the data exposes the contrast between markets with large transaction volumes and those recording higher levels of programmatic penetration, while also identifying Eastern Asia as one of the biggest untapped opportunities.

The Americas generated the largest regional share of pDOOH expenditure in 2025, recording $667 million and a 14.1 percent penetration rate. The United States drove much of that performance with $545.5 million, making it the largest individual pDOOH market globally. Canada followed at $73.1 million and recorded a 15.0 percent penetration rate, placing it fifth worldwide by expenditure.

However, the figures also show that the largest market does not automatically have the highest level of programmatic adoption. The United States recorded 15.9 percent penetration, well below Germany’s 31.8 percent. Belgium, at 25.5 percent, and France, at 16.7 percent, also recorded stronger programmatic penetration rates.

That gap illustrates an important distinction within the market: a country can command substantial digital out of home expenditure without necessarily having the highest proportion of that spending moving through programmatic channels.

Europe, the Middle East and Africa collectively generated $521 million in pDOOH expenditure, representing 9.4 percent penetration. Germany emerged as the standout market for adoption, posting a 31.8 percent programmatic penetration rate, almost twice the level recorded in the United States.

Western Europe contributed $346.7 million and achieved 21.3 percent penetration, further demonstrating the region’s comparatively strong integration of programmatic buying into digital out of home advertising.

The study also highlights differences within Africa. South Africa accounts for the largest concentration of African pDOOH expenditure, although WOO said country level figures are disclosed only where the study’s minimum submission threshold is met.

Asia Pacific presents a contrasting picture. The region generated $151 million in pDOOH expenditure, equivalent to just 1.7 percent penetration. Australia and New Zealand accounted for $92.3 million, representing 61 percent of total APAC pDOOH spending.

Yet the most striking opportunity lies farther north. Eastern Asia, comprising Japan, South Korea and Mainland China, has a combined $7.3 billion digital out of home advertising base but records only 0.6 percent pDOOH penetration.

That disparity gives the region a significant runway for programmatic expansion. WOO identifies Eastern Asia’s large DOOH market and comparatively low level of automated buying as the single biggest structural growth opportunity revealed by the study.

Beyond regional differences, the study also provides insight into how advertisers and media owners conduct programmatic transactions. Private Marketplace, or PMP, deals accounted for 75.7 percent of global pDOOH expenditure, equivalent to approximately $1.014 billion.

The dominance of PMP indicates that most programmatic DOOH activity currently takes place through controlled and invitation based marketplaces involving selected buyers and sellers rather than through open exchanges.

Specialist digital out of home demand side platforms also command a substantial share of the market. OOH focused DSPs generated $877 million, representing 65.5 percent of global pDOOH expenditure.

Platforms identified in the study include Broadsign, DAX, Vistar Media, VIOOH and Hivestack by Perion.

The figures suggest that programmatic DOOH is not simply becoming more automated; it is also developing through transaction structures designed around the particular requirements of outdoor media.

WOO said the credibility of the study rests heavily on its methodology. The 12 participating supply side platforms submitted confidential market level revenue information directly to PwC, which independently aggregated and sense checked the submissions.

Tom Goddard, President of the World Out of Home Organization, said the participation of the SSPs demonstrates the industry’s willingness to improve transparency and establish stronger measurement standards.

Gideon Adey, Principal at GUROOH, who contributed to the study’s measurement methodology, said the research was designed to apply consistent parameters across all 12 SSP submissions.

According to Adey, the findings challenge some assumptions about the global pDOOH market, including Germany’s high penetration rate, New Zealand’s sixth position globally and the concentration of African expenditure in South Africa.However, WOO has made clear that the study should be read within the limits of its methodology.

PwC did not audit or independently verify the individual SSP submissions, nor did it provide assurance on their accuracy, reliability or completeness. Instead, its role was limited to aggregating and sense checking the information supplied by participants.

WOO therefore describes the figures as indicative market estimates. For country level reporting, the study applies a minimum threshold of three SSP submissions. Where that threshold was not achieved, the relevant data could still contribute to regional and global totals but was not disclosed separately for the country.

The study marks a significant step in efforts to quantify the global development of programmatic digital out of home advertising. For advertisers, agencies and media owners, the figures provide a clearer picture of where automated outdoor media buying has gained traction and where adoption remains relatively low.

More importantly, the research demonstrates that the evolution of pDOOH cannot be measured by expenditure alone. The United States dominates in absolute volume, Germany records much higher penetration, while Eastern Asia combines a huge digital out of home base with minimal programmatic adoption.

These differences create distinct opportunities across markets. WOO said the inaugural study establishes a baseline from which the industry can track future changes in expenditure, penetration and transaction models.

The organisation also acknowledged the 12 SSP participants whose confidential submissions made the study possible, as well as PwC for its independent aggregation role and Adey for his contribution to the methodology.

As programmatic technology continues to reshape how outdoor advertising inventory is bought, sold and activated, the new WOO benchmark gives the industry a starting point for measuring that transformation.

The numbers also point to a broader reality: programmatic DOOH is already a billion dollar global market, but its current footprint represents only part of the opportunity available across the world’s digital out of home ecosystem.
