The Ad Market Is Growing Faster Than Ever But Publisher Revenue Is Declining… Here’s Why.

The Ad Market Is Growing Faster Than Ever But Publisher Revenue Is Declining… Here’s Why.

Global advertising spend is projected to reach $1.39 trillion in 2026, according to WARC’s latest forecast — growing 11.5% year over year.

Yes, I double checked those numbers!

The advertising market is bigger than it has ever been in human history, growing faster than most industries, and adding hundreds of billions of dollars in new spend every year.

Publisher programmatic revenues are projected to decline slightly in 2026, according to Madison & Wall.

If you’re a publisher and that disconnect makes you angry, it should. Because the money is real. It’s just not going to you.

Where the Money Is Actually Going

The numbers make the story plain.

Alphabet (Google), Amazon, and Meta controled 56.1% of all advertising spending outside China in 2025, according to WARC. By 2027, that share climbs to 58.8%. Three companies. Nearly 60 cents of every advertising dollar spent outside China.

Almost 80% of all ad spend now flows into retail media, paid search, and social platforms. The remaining 20% is shared across the entire rest of the media industry — every broadcaster, every publisher, every out-of-home operator, every podcast network, every newsletter, every open web property on the planet.

Meanwhile, Google’s Display Network — the world’s largest display advertising network and the primary demand source for millions of publishers — recorded its third consecutive year of declining ad revenue in 2025 and that decline is projected to continue through 2026 and 2027.

So the market is growing, the platforms are capturing the growth, and the open web — where most publishers live — is competing for an increasingly smaller slice of an increasingly larger pie.

Why Publishers Are Losing Ground Even When Advertisers Spend More

This is the part that doesn’t get explained clearly enough. It’s not just that the money is going to platforms. It’s that the structural dynamics of how advertising money moves have fundamentally changed in ways that play against open web publishers specifically.

Fee compression is sending more money directly to platforms.

As WARC noted, fee layers in advertising are shrinking — more of each ad dollar now goes straight to the large platforms rather than passing through intermediaries, this sounds like good news for everyone, but it really isn’t. When a dollar goes directly into Google’s search or Meta’s feed, no publisher sees any of it. When a dollar goes through the open programmatic ecosystem, publishers see a portion, fewer intermediaries means fewer opportunities for open web inventory to compete, and unlike we all hoped, the supply path didn’t really get shortened towards publishers.

Performance budgets are eating brand budgets.

ISBA’s 2026 Media Budgets Survey found 65% of UK marketers plan to increase media budgets in 2026, but only 14% plan to increase performance advertising budgets — compared to 37% who plan to increase brand advertising. This should be good news for publishers, who traditionally benefit from brand spend, but brand budgets have been so heavily cut in favour of performance over the past decade that the recovery, even if real, is starting from a much lower base.

Retail media is the fastest-growing channel — and publishers don’t own any of it.

McKinsey estimates US commerce media networks could exceed $100 billion in ad spending by 2026, growing at 21% annually, Amazon, Walmart, Target, and hundreds of retailers now operate sophisticated advertising platforms. Nearly 70% of advertisers say they see better performance in retail media networks than in other channels, and 82% say they plan to increase spending in retail media.

None of that money is going to open web publishers. All of it is going to companies that own the point of purchase — retailers who built their own closed-loop advertising systems using the data advantage that publishers simply don’t have.

The Two-Speed Market No One Is Talking About Honestly

WARC describes the current advertising landscape as a “two-speed market.” Digital-native categories and new market competitors direct their budgets almost entirely to the major platforms.

What that means in practice: the fastest-growing advertisers — the ones with the biggest growth budgets, the most data, and the most sophisticated targeting approaches — are the ones least likely to spend with open web publishers, while the advertisers most likely to spend with publishers are the ones with flat or declining budgets.

This is a structural problem, not a cyclical one, and It won’t fix itself as the market grows further

What Publishers Can Actually Do About It

This is not an argument for despair, It’s an argument for strategy.

The publishers capturing meaningful revenue in this environment share a few characteristics. They’re not waiting for programmatic display to recover, they’re building revenue streams that platforms can’t replicate or absorb.

Premium direct-sold inventory is outperforming programmatic display.

Publishers who have built direct advertiser relationships — where they sell inventory directly to brands rather than routing everything through an exchange — are achieving pricing and margins that open auction inventory can’t match. Direct relationships require investment in sales infrastructure and audience packaging, but the upside is that they generate revenue that doesn’t flow through platforms at all.

First-party data is the competitive advantage platforms can’t take away.

Publishers who know their audiences — really know them, with consented, enriched, first-party data — can offer something platforms can’t: A genuine contextual and audience signal that doesn’t depend on tracking infrastructure that’s eroding. Digiday research from back in Q1 2025 shows 71% of publishers said first-party data drives positive ad results, up from 64% the year before, and 85% expect its role to increase further this year.

Video and CTV are where the premium pricing is.

While display ad revenue declines, video advertising is growing at a 9.54% annual rate through 2030, according to Statista, with CTV ad spend projected to exceed $46 billion by EOY 2026. Publishers who have built video capabilities — not just embedded YouTube players, but owned video inventory with programmatic access — are accessing CPMs that display simply doesn’t generate.

Supply chain hygiene is now a revenue issue, not just a compliance issue.

As more budget moves through curated private marketplaces rather than the open auction, the publishers with clean, well-structured supply chains — proper ads.txt declarations, accurate sellers.json entries, correct MANAGERDOMAIN configuration — are the ones whose inventory gets found and bid on by quality demand while the publishers running messy supply chains are increasingly invisible to the buyers with real budget.

The Honest Summary

The advertising market will be worth $1.39 trillion by the end 2026. Publishers will see a smaller share of that than they did last year, which was smaller than the year before that.

The money isn’t disappearing. It’s consolidating in fewer hands, and it’s concentrating in places — platforms, retail media, closed ecosystems — that are structurally inaccessible to most web publishers.

The publishers who come out of this period in reasonable shape won’t be the ones who waited for the market to turn in their favour, they’ll be the ones who built things that platforms can’t replicate: direct relationships, owned audiences, first-party data, premium formats, and clean supply chains.

The market is growing. The question is whether you’re positioned to grow with it.
