The DOOH consolidation map (2023–2026)

In under three years the DOOH supply side reorganised itself. A string of acquisitions pulled the major platforms into a handful of full-stack groups, backed by telco and data money. For a beauty network deciding where to plug in, this matters: the routes to programmatic demand are now fewer, clearer and more consolidated. This map lays out the deals and what they mean.

The deals

Three acquisitions reshaped the supply side, plus the standing JCDecaux/VIOOH axis (primary):

Deal	When	Result
Hivestack → Perion	Dec 2023 (~$100M)	Hivestack’s programmatic stack inside Perion’s ad-tech group
Vistar → T-Mobile	closed Feb 2025 (~$600M)	The largest DOOH marketplace inside a telco with first-party data
Broadsign → Place Exchange	Nov 2025 (~1.7M combined screens)	CMS + SSP combined into one of the largest programmatic footprints
JCDecaux / VIOOH	standing	The world’s #1 OOH owner with its exclusive SSP

The pattern is consistent: standalone DOOH platforms folding into larger groups with deeper pockets and adjacent assets — connectivity (T-Mobile), broader ad-tech (Perion), full-stack CMS-plus-supply (Broadsign), and global inventory (JCDecaux).

The new map: four anchors

The result is a supply side organised around four anchors, each combining some mix of CMS, SSP and inventory:

T-Mobile / Vistar — the largest DOOH marketplace, now with a telco’s first-party data behind it.
Perion / Hivestack — a programmatic stack inside a broader ad-tech group, across many markets.
Broadsign / Place Exchange — CMS plus SSP, ~1.7M screens, one of the largest programmatic footprints.
JCDecaux / VIOOH — the dominant global OOH owner and its exclusive supply platform.

Most programmatic DOOH demand now flows through these groups or connects to them — and over 95% of it transacts on deal IDs, increasingly through these consolidated routes.

Why it’s consolidating

Two forces drive it. First, scale economics: programmatic DOOH rewards breadth — a buyer wants one integration that reaches many screens, and a platform with more inventory and more DSP connections is more valuable, which pushes the industry toward fewer, bigger players. Second, money from adjacent giants: telcos (first-party location/identity data), ad-tech groups (cross-channel demand) and global OOH owners all have reasons to own DOOH rails, and the capital to buy them. The combination turns a fragmented field of specialists into a handful of full-stack anchors.

What it means for a beauty network

Consolidation is mostly good for a beauty operator, because it simplifies the hard part — reaching demand:

Fewer SSPs reach the whole demand base. Integrating with one or two anchors now connects you to a large share of programmatic demand, rather than stitching together many small platforms.
Integration is more valuable; going it alone is less viable. The leverage is in plugging into a consolidated route, not building a bespoke one — reinforcing the “wire up programmatic early” posture from Landing your first advertisers.
Pick an anchor deliberately. When you evaluate an operator or your own integration path, ask which anchors they connect to — that determines which demand can find your salon inventory.
The demand still has to find you correctly. Consolidation doesn’t change the one beauty-specific requirement: classify screens under Health & Beauty → Salon/Spa so the consolidated demand can target them.

The honest caveat: consolidation also concentrates leverage on the supply platforms’ side, which can affect take rates and terms over time. But for a young network whose core challenge is reaching demand at all, fewer, clearer routes is a net help.
