80% of the World's Marketing Teams Are Using AI. Who Are the Remaining 1%?

A couple of days ago I came across a report, and halfway through, I sat up straight.

Not because it scared me — because a single number hit me right between the eyes.

Only 1% of companies worldwide say they "don't use AI for marketing at all."

1%.

Think about what that means. It means AI in marketing is no longer a "should we or shouldn't we" question. It's a "how much time do you have left to catch up" question.

This report is from Nielsen, called From Chaos to Clarity: Unlocking the Power of Data-Driven Marketing, based on their 2025 global annual marketing survey. Let me unpack the numbers that made me sit up and pay attention, piece by piece.

The Most Interesting Thing: What People Care About Most Isn't Saving Money — It's "Understanding You"

Guess which trend global marketers care about most right now?

Cost reduction and efficiency? Nope.

Data platforms? Nope.

It's "using AI for personalization."

59% of global marketers rank it as the number-one trend. Latin America 63%, Asia-Pacific 62%, North America 60%, and even typically measured Europe sits at 50%.

What does personalization mean?

Plainly put: you just searched for a pair of size-42 running shoes on an app, and the next second your feed is showing you color variants and reviews of the same model — it even guessed your running habits. The old "blast by age group" approach feels crude now. What people want is one-to-one.

Delta Air Lines did something in 2025: they launched an AI assistant called Delta Concierge inside the Fly Delta App. Check-in, baggage, gate changes, meals — it handles every step of your trip for you. The goal: let you worry less.

You see, what AI does in marketing has long moved beyond writing a couple of lines of copy. It's acting as the brand's way of "getting to know you."

The essence of this shift is upgrading "I think you'll like this" to "I'll help you make this decision."

What Really Stunned Me: The Penetration Rate of This "Grunt Work"

Here's a set of numbers from the report — let me lay them all out:

• 50% of companies use AI for data quality validation
• 47% use AI for content production
• 46% use AI for predictive analytics
• 44% use AI for audience segmentation
• 43% use AI to evaluate creative performance
• 42% use AI for personalization
• 39% use AI for public opinion and sentiment analysis

You might think that creative evaluation and sentiment analysis sound a bit abstract.

But do the math.

A mid-sized brand runs dozens or even hundreds of ad versions a year. For each version — should we run it? How much should we spend? Which image gets a higher click-through rate? Which copy converts poorly? In the past, humans had to babysit all of that, and they couldn't keep up. Now AI runs through it in a second and labels the sentiment — positive or negative — crystal clear.

What you save isn't time — it's the number of "gut-feel" decisions.

This isn't me making things up. 80% of global companies are already using AI "to a considerable extent" or "to a great extent" in their marketing measurement. North America and Latin America each at 85%, Asia-Pacific 84%, Europe 65%.

That 1% who say they don't use it — I'm genuinely curious who they are.

The Cookie Situation Made AI a Hard Necessity

This one needs some context.

Back around 2020, Google announced it would kill third-party cookies in Chrome, and global marketers went into a full-blown panic. Then Google changed its mind: it wouldn't forcibly remove them — it would let users choose whether to be tracked.

Sounds like a sigh of relief?

Not quite.

Because users will most likely choose "don't track me."

This means the entire playbook that marketers have relied on for twenty years — "track user behavior via cookies" — is losing its grip. 42% of global marketers already clearly recognize that privacy regulations and the cookieless wave will rewrite the industry's foundational logic.

So what do you do?

The answer is still AI. Except this time, what it feeds itself is first-party data and contextual signals: data you've explicitly authorized, plus what you're looking at right now, your location, the current weather. It's not peeping at you — it's inferring based on "you, right now."

Which is really saying: the tighter the privacy, the more expensive AI becomes.

Some Uncomfortable Truths

By the time I finished the report, I had a few complicated feelings.

First: the deeper AI penetrates, the more the marketing profession itself is being rewritten. It used to be about "creativity" and "feel." Now you also have to add "who can actually use AI well." The skill stack is shifting, and people have to shift with it.

Second: the gap in global adoption is smaller than you'd expect, but Europe is clearly a beat behind. 65% versus 85% — a 20-point difference. Is it tighter regulation, or a talent shortfall? The report doesn't say, but I suspect both.

Third — and this is the one that left me at a loss for words: sustainable and values-driven marketing ranks as the second-biggest trend (51%), and authenticity and influencer/creator content ranks third (47%). Marketers are using AI to pursue being "more understanding" and "more genuine."

These two things sitting side by side — that in itself is worth sitting with.

I don't know the answer either. But this question is worth every brand owner thinking hard about at three in the morning, staring at the ceiling.
