Programmatic DOOH buyers expect to increase investment by 44% over the next 18 months, with the channel projected to appear in nearly half of all campaigns globally.
Programmatic DOOH just crossed the confidence threshold. Buyers now trust it more than traditional outdoor.
Among recent buyers of programmatic digital out-of-home advertising, 99% plan to increase or maintain their investment. The average anticipated uplift is 44% over the next 18 months. The channel is forecast to appear in nearly half of all campaigns globally, up from 34% in the previous 18-month period.
This is not a fringe channel anymore. Programmatic DOOH is projected to account for 65% of all US digital out-of-home spend by 2029. For the first time, buyer confidence in programmatic DOOH's return on investment now exceeds standard DOOH. Sixty percent of global respondents say pDOOH is likely to deliver ROI, compared to 56% for standard DOOH and 52% for traditional OOH.
The growth is coming from incremental budgets, not cannibalisation. New money is entering outdoor advertising rather than migrating from static formats. That is a healthy signal. It means programmatic DOOH is expanding the pie rather than reshuffling it.
But there is a structural constraint. Limited DOOH inventory is slowing adoption. The 14.5% growth forecast for digital out-of-home in 2026 is strong, but it represents a meaningful slowdown from recent years. Supply, not demand, is the bottleneck.

US out-of-home ad spend is projected to hit $4 billion in 2026. The digital share keeps climbing but physical screen deployment cannot keep pace with advertiser demand. Markets with dense DOOH networks like Sydney, Melbourne and Brisbane are better positioned than regional areas where inventory remains sparse.
Why it matters
For digital marketers who have never touched outdoor, programmatic DOOH removes the barriers. You buy it the same way you buy display. You target by audience, location and time of day. You measure it against the same attribution models. The creative can be dynamic, triggered by weather, time or audience composition data from mobile signals.
The ROI confidence numbers are the real story. When buyers trust a channel's return, budgets follow. Expect programmatic DOOH to start appearing in more media plans alongside paid social and search, not as an experimental line item but as a core channel.
What to do about it
If you are running paid media for an Australian business with a physical presence, test programmatic DOOH in one market. Start with a four-week campaign targeting a 2km radius around your highest-performing location. Use the same audience segments you run on Meta or Google and compare cost-per-visit.
If you are an ecommerce or SaaS business, the channel is less relevant today. But watch the targeting capabilities. As mobile signal data improves, programmatic DOOH will become viable for digital-first brands targeting specific professional or demographic audiences in high-density areas.
