The State of DOOH in 2026: What the Numbers Actually Say
| Industry Trends
Every year the trade press runs some version of the same headline. *DOOH is the fastest-growing ad medium.* And every year, the numbers keep backing it up.
I've stopped being surprised. But I do think it's worth looking at what's actually driving it — because "fastest growing" doesn't tell you much by itself.
## The Growth Is Real. Here's Where It's Coming From.
Global DOOH spend is projected to nearly double by 2029, reaching [close to $30 billion](https://www.statista.com/topics/11608/digital-out-of-home-advertising-worldwide/). U.S. growth is running [double digits year-over-year](https://www.emarketer.com/content/dooh-regains-its-footing-after-few-turbulent-years) — well above linear TV, print, and most digital display.
But it's not evenly distributed. The categories pulling the numbers are place-based networks — gyms, bars, restaurants, healthcare waiting areas — programmatic DOOH transactions, which grew [over 60% year-over-year as recently as 2023](https://newdigitalage.co/dooh/programmatic-dooh-in-2024-the-cross-channel-opportunity/) and U.S. buyers are forecasting another [49% increase over the next 18 months](https://www.tastyad.com/us-programmatic-dooh-spend-set-to-rise-49-as-market-enters-its-next-phase-of-growth/), and retail media networks with in-store screens.
Indoor is a big part of that story. *Not a footnote.*
## Why Budgets Are Actually Moving
Three things changed. And they happened fast enough that a lot of buyers missed it.
**Measurement caught up.** Geopath made DOOH impressions auditable and comparable to other digital channels. Buyers can defend the spend in the same dashboards they use for everything else. That matters more than people realize — *if you can't report on it, you can't justify it.*
**Programmatic made it frictionless.** A buyer can spin up a DOOH campaign through the same DSPs they already use for display, video, and CTV. No separate insertion orders. No three-week lead times. [It just works now](/programmatic).
**Brand safety pressure got real.** As programmatic display keeps dealing with fraud, MFA sites, and suitability issues, advertisers want environments where the inventory is *physically real*. A screen in a venue can't be a bot. **Full stop.**
## What It Means for Indoor Specifically
Indoor placements — restrooms, common areas, bar tops, lobbies — sit at the higher-attention end of the DOOH ecosystem. Same tailwinds as the broader category. Less saturation than high-traffic urban screens.
If you haven't tested place-based or indoor inventory in the last 18 months, the buying experience has changed materially. *Worth a conversation.*
