Kroger's $30 Billion Side Hustle Has a Hole You Could Drive a Truck Through

Walk a Kroger aisle and you pass two of the most profitable ideas in modern retail without noticing either. One is the small sponsored tile that nudges you toward a particular brand of pasta sauce — an ad, sold by Kroger, targeted using the purchase history of 60 million households.⁵ The other is the can of store-brand tomatoes sitting one shelf below the name brand, quietly carrying a fatter margin. Together they're sold as Kroger's future: a grocer that learned to print high-margin money on top of low-margin groceries. The story is mostly true. The trouble is you can't actually see the money.

The official story is that Kroger has two booming, transparent flywheels — a retail-media network growing 17% and a $30 billion private-label juggernaut. The truer story is that one of those numbers lives inside a blended line item nobody can pry open, and the other is a sentence a CFO said out loud on a call. The structure is real. The scoreboard is missing.

The 17% that isn't a dollar figure

Here is the part the headlines skip. When Kroger reports that media revenue grew 17%, that growth rate floats free of any disclosed base. The actual money is reported inside a bucket called Alternative Profit Businesses, which posted $1.35 billion in operating profit in fiscal 2024.¹ But that bucket also holds data-analytic services and other streams — so the ad business and the data business and whatever else is in there arrive pre-blended.² The 10-K calls these streams 'fast-growing, high operating margin' and credits twenty years of data-science investment, and then it stops.² It never breaks Kroger Precision Marketing out as its own line. You're handed a growth rate with no denominator and a profit pool with no breakdown. A percentage you can't multiply by anything is a mood, not a metric.

That phrasing is the tell. By mid-2025, CPG advertisers had pulled back on spending, and the CFO's reassurance was a qualitative one — 'healthy,' 'expected to maintain' — precisely because there was no public number to point at.⁸ When a business is genuinely large and durable, companies tend to disclose it; Amazon broke out advertising, Walmart talks up Walmart Connect. Kroger keeps the most celebrated part of its growth story tucked inside a line item it never opens. That's a choice, and choices that hide good news are worth a second look.

The $30 billion that came from a CFO's mouth, not a filing

The private-label side has the same shape. Our Brands is real and it's enormous: more than 13,000 items, over 900 new products launched in a single year, and more than 90% of customer households buying at least one of them.³ Numerator, looking at outside scanner data, pegs Kroger's private label at roughly 27% of sales volume — and found its value brand, Smart Way, was the fastest-growing store brand in the country, up 135%.⁴ Those are independently sourced, and they're impressive. But the headline figure — $30 billion in annual Our Brands sales — traces to one place: CFO Todd Foley said it on the March 2025 earnings call, and the trade press repeated it.³ It is not a segment disclosure in any 10-K or 8-K table. It's attributed to a source, not documented in an audited statement.

The data moat Kroger borrowed before it built it

Here's the deeper reason both businesses can work even when the numbers are murky. They run on the same asset — loyalty-card purchase data — and they reinforce each other. The data tells Kroger which brands to copy as private label and which CPGs to sell ads to; the private-label growth and the ad sales both deepen the data. That's the dual flywheel everyone admires, and the engine underneath it is 84.51°, the analytics subsidiary that powers Kroger Precision Marketing and its reach into 60 million households.⁵ KPM itself launched in 2017 and has since worked with roughly 2,000 brands including Nestlé, P&G, and General Mills.⁵

But the popular version — that Kroger grew this capability organically, a quiet grocer that secretly became a data company — skips the most interesting fact. The lineage started in 2003 as DunnhumbyUSA, a joint venture with the UK retailer Tesco. Kroger didn't own the engine outright until 2015, when that JV ended and Kroger acquired the assets to create the wholly-owned 84.51°.⁶ The moat wasn't sprung from Kroger's own forehead; it was rented for a decade, then bought. That matters strategically: the capability that now looks like a unique, century-deep advantage was in fact licensed know-how Kroger had the foresight to internalize. The 2023 decision to in-house its self-serve ad platform off Microsoft's PromoteIQ was the same instinct repeating — owning the rails rather than renting them.⁷

Isn't opaque disclosure just normal — and the flywheel still real?

The fair objection is that this is nitpicking. Plenty of strong businesses don't segment-report every line, and the qualitative signals here are genuinely good: 27% private-label penetration is a real number from an outside firm, Smart Way's 135% growth is a real number, 90%-plus household reach is a real number.⁴³ The flywheel mechanism is sound regardless of how it's reported. All true. But there's a difference between believing a business is good and being able to size it, and the gap between those two is exactly where hype lives. The honest counter to the skeptics is that the structure clearly works — Kroger has a genuine, hard-to-copy data asset and two adjacent businesses that feed on it. The honest counter to the boosters is that the two most-quoted numbers in the whole story — the 17% and the $30 billion — are the two you cannot verify in a filing. A thesis that rests on its least-documented figures is a thesis built to be repeated, not tested.

So Kroger has done something genuinely clever and slightly evasive at once. It built — partly bought, then built — a data engine that lets it sell ads against the same shelf where it sells its own brands, two high-margin businesses bolted onto a low-margin grocery base. The mechanism is real. The reach is real. The opacity is the strategy: keep the most flattering numbers blended, spoken, and unaudited, and let the trade press do the sizing. The next time you read that Kroger's media business grew 17%, ask the only question that matters — seventeen percent of what? The company has gone to some trouble to make sure you can't answer.
