Recent figures released by the Out of Home Advertising Association of America show that total OOH ad spend grew 3.2% during 2025’s third quarter, passing its growth in Q1 (2%) and Q2 (3%) and the first half of the year’s +2.6%.

The OAAA shows the growth was clearly driven by digital out-of-home advertising, with spend up 11.6% in Q3 2025, accounting for 35% of sales for the quarter. Digital also saw greater gains than either of the year’s first two quarters, when spend was up 9%.

It’s yet to be seen whether 2025 will surpass last year’s 4.5% out-of-home spend increase, during a record-setting year for U.S. OOH ad revenues, but it should be noted that Q3 2025 – the 18th consecutive quarter with year-over-year growth – was the highest-grossing third-quarter ever, at $2.13 billion, according to the OAAA.

Looking further ahead, a Marketing Charts analysis also notes a recent forecast projecting a 2.2% compound annual growth rate for out-of-home advertising in the U.S. from 2024 through 2029.

The OAAA’s report also shows that transit advertising was the fastest-growing OOH category in Q3, up 11.4%, while three ad categories saw double-digit spending growth: financial services (up 35.5%), insurance and real estate (+26.8%) and communications (10.3%).

OOH’s top-spending category was again legal services – with Morgan & Morgan leading all advertisers in spending during Q3 – followed by hospitals, clinics and medical centers, consumer banking, domestic hotels and resorts, and computer software. Nearly two-thirds (65) of the top 100 out-of-home advertisers increased spend year-over-year, with 19 more than doubling their spend.

According to the OAAA, tech and direct-to-consumer brands accounted for nearly 30% of America’s top 100 OOH advertisers, including 13 of the top 30. Top advertisers in these categories were Geico, Apple, Verizon, T-Mobile, Amazon, Samsung, Progressive, Google, Netflix, Uber, HBO, FX and Paramount+.

Also notable are results from a OneScreen.ai survey of more than 100 senior business-to-business marketers, finding that 46% already use OOH, while an additional fifth are actively considering it.
