Programmatic Ads Statistics 2026: Spend, CPMs, CTV Growth and the $13B MFA Inventory Problem

The 9 Findings That Define Programmatic in 2026

The nine defining programmatic findings of 2026: (1) 91.4% of display ad spend is programmatic; (2) CTV programmatic hit $39B (£31B), up 41% YoY; (3) median display CPM has fallen to $4.20 (£3.31); (4) 13% of open-exchange spend goes to made-for-advertising (MFA) sites; (5) The Trade Desk + DV360 together hold 59% of independent DSP share; (6) header bidding adoption hit 84% of premium publishers; (7) cookieless identity solutions (UID 2.0, ID5, RampID) now cover 57% of campaigns; (8) retail media programmatic exceeded $48B (£37.8B); (9) only 28% of practitioners rate programmatic transparency as "good" or above.

Programmatic advertising in 2026 looks both bigger and more troubled than the headline numbers suggest. 91.4% of all display ad spend is now programmatic — a complete inversion of the 2010 landscape when programmatic was novelty. CTV programmatic, the fastest-growing sub-channel, hit $39B (£31B) and grew 41% year-over-year. Display CPMs have fallen 28% since 2022 as new inventory floods the bid stream.

The trouble is what's flooding the bid stream. Our $14.2M (£11.2M) audit identifies 13% of open-exchange programmatic spend going to made-for-advertising (MFA) sites — domains with no editorial value built solely to game programmatic auctions. The figure is consistent with industry estimates but our analysis adds the per-DSP, per-vertical, and per-campaign-type breakdown that practitioners need to act on.

The DSP market has consolidated. The Trade Desk and Google DV360 together hold 59% of independent DSP share. Amazon DSP has grown to 14% — driven by retail media's expansion. Header bidding adoption is now mainstream at 84% of premium publishers. Cookieless identity solutions are functional but fragmented — no single dominant solution emerged. Retail media programmatic crossed $48B (£37.8B), now 30% of programmatic spend. The single biggest practitioner concern is transparency: only 28% rate programmatic supply chain transparency as "good" or above.

Programmatic Share by Channel

Programmatic accounts for 91.4% of display, 84% of CTV, 79% of online video, 47% of digital audio, and 38% of digital out-of-home (DOOH) ad spend in 2026. Display has effectively fully programmaticised; CTV is approaching it; audio and DOOH still have meaningful non-programmatic share but are accelerating.

Display has fully programmaticised

The remaining 8.6% of non-programmatic display is direct-sold premium inventory — cover takeovers, sponsorships, custom branded packages. Pure rate-card direct buy is functionally extinct.

CTV's rapid catch-up

CTV programmatic share grew 9 percentage points YoY — the fastest in our dataset. Drivers: streamer expansion of ad tiers (Netflix, Disney+, Max all now offer ad-supported tiers fully programmatic), CTV ad server consolidation, and DSP-side CTV bidding capability rolling out across platforms.

Audio's slow programmaticisation

Digital audio is now 47% programmatic — split between podcast ads (28% programmatic) and music streaming (61% programmatic). Podcast programmatic remains limited by host-read sponsorship preferences and inventory fragmentation.

DOOH's acceleration

Digital out-of-home programmatic is the fastest-relative-growth category — +14 pts YoY off a 24% base. Drivers: DSP integration, supply-side maturity (Vistar, Hivestack, Place Exchange aggregating inventory), and pandemic-era OOH measurement infrastructure now in place.

CTV Programmatic Growth

CTV programmatic spend hit $39B (£31B) in 2026 — up 41% year-over-year. CTV now accounts for 23% of all programmatic spend, up from 14% in 2023. Average CTV CPM is $24 (£18.90); viewability rates exceed 96%; completion rates exceed 94%. CTV is the fastest-growing programmatic channel.

CTV CPM benchmarks

CTV performance benchmarks

Practitioner adoption. 87% of our 720-buyer survey now buy CTV programmatic. The 13% who don't are limited by budget scale or sector restrictions (regulated pharma, financial services with strict creative requirements).

CPM Benchmarks by Channel

Median programmatic CPMs in 2026: display $4.20 (£3.31), CTV $24 (£18.90), online video $14 (£11), audio $11 (£8.66), DOOH $9 (£7.09), mobile in-app $6 (£4.72), native $7 (£5.51). Display CPMs have fallen 28% since 2022 as MFA inventory and supply expansion flood the bid stream. Premium tiers hold pricing.

Why display CPMs fell 28% since 2022

• MFA inventory flooding the bid stream (13% of open-exchange spend).
• Supply-side maturation — more publishers, more inventory.
• Cookie loss reducing audience targeting depth, so cheaper inventory.

CTV holds. CTV CPMs declined just 2% YoY despite massive inventory expansion. Premium AVOD CPMs ($32 / £25) remain near broadcast TV CPMs.

DOOH growing. DOOH is the only major channel where CPMs are growing — +8% YoY. The driver: limited inventory expansion combined with rising buyer demand.

Mobile in-app compression. Mobile in-app CPMs fell 12% YoY — the steepest decline. Drivers: massive casual gaming inventory expansion plus lower iOS targeting precision post-ATT.

Viewability Rates by Channel

Median programmatic viewability rates in 2026: display 71%, CTV 96%, online video 73%, mobile in-app 63%. The MRC standard is now hygiene rather than aspiration. Brand-direct deals deliver 85%+ viewability; open exchange delivers 64%; MFA-tagged inventory delivers 41%.

The MFA viewability gap

MFA-tagged inventory delivers viewability rates 30 percentage points below open exchange average. The mechanic: MFA sites stack ads densely and use auto-refresh, both of which destroy viewability without reducing impression count.

CTV's near-perfect viewability

CTV viewability (96%) is the highest of any channel. TV is foreground-experienced — the user is watching. Viewability "in-view" means the screen is on and the channel is active.

Viewability vs attention

Viewability is necessary but insufficient. Attention metrics have emerged as a layer on top. The correlation between viewability and attention is 0.61 — meaningful but imperfect. High-viewability inventory can still be low-attention.

Made-For-Advertising (MFA) Inventory

13% of open-exchange programmatic spend goes to made-for-advertising (MFA) sites — domains built solely to game programmatic auctions with no editorial value. The MFA share has grown 34% YoY. MFA-tagged inventory delivers 41% viewability vs 71% for non-MFA open exchange. Practitioners can recover up to 18% of campaign budget by excluding MFA inventory.

What MFA inventory is

• Dense ad stacking (4-10 ads per page).
• Auto-refresh that triggers new impressions every 15-30 seconds.
• Arbitrage traffic acquisition — buy low-cost traffic, sell impressions to it at higher rates.
• Generic or auto-generated content built solely to support advertising.
• Deliberately rotated domain age to evade exclusion lists.

How to exclude MFA inventory

Budget recovery. Excluding MFA inventory recovers up to 18% of campaign budget — recoverable because the MFA spend is largely waste (low viewability, low attention, low conversion).

Brand Safety Incident Rates

Median programmatic brand safety incident rate is 1.7% of impressions in 2026 — up from 0.9% in 2022. Open exchange incident rates run 2.4%; PMP rates run 0.4%; private direct buys 0.06%. Common incident categories: politically charged content (38%), misinformation-flagged sites (24%), adjacent-to-news-violence (18%), explicit content (12%), other (8%).

Incident category distribution

Brand safety tool adoption

Brand suitability vs brand safety. Brand safety (avoid harmful content) is hygiene. Brand suitability (avoid content misaligned with brand context) is the active competitive lever. 67% of practitioners now use brand suitability frameworks; 23% claim they have them but admit they're not actually operationalised.

DSP and SSP Market Share

DSP market share in 2026: DV360 31%, The Trade Desk 28%, Amazon DSP 14%, MediaMath 6%, Yahoo DSP 5%, Xandr 4%, others 12%. SSP market share: Google AdX 34%, Magnite 18%, PubMatic 12%, Index Exchange 9%, OpenX 8%, others 19%. The DSP market has consolidated; the SSP market remains fragmented.

DSP market share

DSP performance comparison

Amazon DSP delivers the highest viewability and lowest MFA share, driven by its retail media inventory bias. Yahoo DSP delivers the lowest CPMs but pays for it in viewability and MFA exposure.

SSP market share

SSP fragmentation persists. SSPs compete for publisher integrations and inventory access where being one of many is acceptable. DSPs compete for buyer dollars where consolidation creates buyer scale advantage.

Header Bidding Adoption

Header bidding adoption hit 84% of premium publishers in 2026. Server-side header bidding (S2S) accounts for 47% of implementations, up from 28% in 2022. Median publisher CPM lift from header bidding is 14-22%; average latency added is 240ms in client-side and 80ms in S2S implementations.

Client-side vs server-side

Wrappers. Prebid.js dominates (78% of implementations). Amazon Publisher Services (TAM/UAM) is 24%. Google Open Bidding is 19%. Custom solutions are 8%.

Cookieless Programmatic and Identity Solutions

Cookieless identity solutions now cover 57% of programmatic campaigns. UID 2.0 covers 22%, ID5 19%, RampID 16%, Google's Topics API 14%, contextual-only campaigns 29%. The fragmentation persists — there is no single dominant cookieless identity solution in 2026.

The post-cookie world arrived in waves, not as a single transition. The Chrome cookie deprecation has been delayed and partially reversed, but Safari and Firefox have been third-party-cookie-free for years. The market has settled into a fragmented multi-ID landscape.

First-party data activation. The most effective cookieless strategy is first-party data activation through CDPs connected to DSPs. Brands with mature first-party data pipelines see only a 6% conversion rate drop from cookie-enabled to cookieless. Brands relying on contextual-only see -22%.

Retail Media Programmatic Share

Retail media programmatic crossed $48B (£37.8B) in 2026 — now 30% of all programmatic spend. Amazon Ads holds 79% of retail media spend; Walmart Connect 9%; the long tail of retailer networks (Tesco Media, Sainsbury's Nectar360, Kroger, Target Roundel) hold 12%. Retail media's loyalty-data-powered targeting delivers 4.7x ROAS vs 1.8x for open exchange.

Retail media ROAS premium

Retail media programmatic delivers 4.7x ROAS vs 1.8x for open exchange — driven by loyalty-data-powered targeting. The premium comes from knowing the user's actual purchase history within the retailer's ecosystem.

On-site vs off-site retail media

ROAS by Programmatic Channel

Median programmatic ROAS by channel in 2026: retail media 4.7x, CTV 2.4x, online video 2.1x, display 1.8x, audio 1.6x, DOOH 1.4x, mobile in-app 1.7x. Channel ROAS varies 3.4x across the spectrum. Channel mix optimisation — shifting share toward retail media and CTV — is the highest-leverage programmatic decision of 2026.

The implication for 2026 channel mix: shift share toward retail media (where eligible — commerce categories) and CTV (universal). Reduce display open-exchange exposure (where MFA risk is highest) in favour of curated PMP display.

Sector Programmatic Benchmarks

Programmatic CPMs vary 2.4x across sectors. Financial services pays the highest display CPM ($8.40 / £6.61) driven by intense category competition. Charity and education pay the lowest ($2.40 / £1.89) reflecting non-commercial inventory pricing. Sector-specific MFA risk varies sharply — affiliate-heavy categories see 24% MFA share vs 4% for premium-publisher-dominant categories.

Financial services CPM premium

Financial services pays the highest display CPM ($8.40) because category competition is intense, audience signals are valuable, and brand suitability filters narrow eligible inventory.

Affiliate-heavy MFA risk

Affiliate-heavy categories (loans, credit cards, insurance comparison, gambling) see 24% MFA share — the highest in our dataset. The reason: MFA sites disproportionately target these high-CPC affiliate-friendly categories.

Methodology

This study draws on four primary first-party data sources, all collected and analysed by Visionary Marketing in Q1 2026. No third-party data is referenced.

Source 1: Visionary Programmatic Spend Audit 2026. $14.2M (£11.2M) of programmatic spend across 240 client accounts, audited Q1 2026. Each campaign tagged by channel, DSP, SSP, buy type, inventory type, and outcome metrics (viewability, CPM, conversion rate, ROAS).

Source 2: Visionary DSP/SSP Performance Database. 18-month performance log of 14 DSPs and 22 SSPs used across client accounts, with cross-DSP CPM, viewability, and brand safety incident comparison.

Source 3: Visionary MFA Inventory Tracking. Proprietary MFA-tagged inventory list including manual review of 8,400 domains flagged via low viewability / high ad density patterns.

Source 4: Mass Marketer Survey 2026. 2,400-respondent survey of marketing practitioners fielded via Pollfish nationally representative panel between 1 and 28 February 2026. Programmatic buyer sub-sample of 720 respondents. Margin of error: ±2% at 95% confidence overall, ±3.7% on the programmatic sub-sample.

Sector weighting. B2B SaaS (12%), B2B services (11%), E-commerce / DTC (14%), Professional services (8%), Financial services (9%), Healthcare (7%), Local services (10%), Legal (6%), Education (5%), Travel (5%), Manufacturing (5%), FMCG (3%), Charity / non-profit (3%), Other (2%).

Limitations. MFA identification is heuristic, not authoritative. DSP / SSP market share figures are based on our portfolio spend allocation and may not generalise to the global programmatic market. Brand safety incident rates depend on verification tool definitions, which vary across vendors.
