Two German Discounters Entered America. Only One Cracked It.

In 1976, in a strip mall called the Kmart Plaza in Iowa City, a German company opened a grocery store unlike any American had seen: about 450 items, no name brands to speak of, products stacked in their shipping cartons.¹ It was Aldi's first attempt at the United States. It lasted barely eighteen months. The building was simply too big to run the Aldi way, and by the end of 1977 the doors were shut.¹ If you wanted to bet against German discounters in America, that was your moment.

The story that gets told today is that two German discounters, Aldi and Lidl, cracked the US grocery market. That telling is tidy, symmetrical, and wrong. Aldi did not crack anything quickly, and Lidl has not cracked it at all.

Here is the thesis a smart friend could repeat: Aldi won America by being almost embarrassingly slow — converting one building at a time, building density before scale, earning trust over nearly five decades — while Lidl arrived in 2017 with a playbook and a checkbook, and discovered that money cannot buy the one thing Aldi spent forty years compounding.

The first store failed, and that was the lesson

Notice what actually happened in Iowa City. Aldi did not parachute in with a purpose-built flagship. It entered quietly, converting an existing grocery building someone else had already operated, and stocked it with a deliberately tiny range.¹ When the format didn't fit the box, Aldi didn't double down — it closed and went away. That is not the behavior of a company chasing a land grab. It is the behavior of a company that treats the store itself as the unit of discipline. A store too large to run the Aldi way isn't a smaller margin; it's a broken machine, and Aldi would rather not run it. The discipline that looked like failure in 1977 was the same discipline that would carry the chain to 2,428 stores in 39 states by late 2024.³

The whole Aldi model is a refusal to do most of what a grocer does. Carry a few hundred SKUs instead of tens of thousands, mostly private label, and your buying power per item becomes enormous; sell from the carton and your labor per shelf collapses; standardize the box and every new store is a copy of a machine you already know how to run. Each constraint feeds the next. The narrow range is what makes the low price possible, and the low price is what builds the trust, and the trust is what fills the next identical box. That is why the slow rollout was not timidity. It was the cost of keeping the machine intact at every step — and a machine you can replicate cheaply is one you can compound for decades.

Lidl brought the format. It couldn't bring the forty years.

Lidl entered the US in June 2017, opening nine stores across Virginia and the Carolinas, backed by a serious commitment — an initial $202 million investment in headquarters and distribution announced two years earlier.⁴ On paper it was the same kind of company: a German hard discounter with a lean, private-label-heavy format. The expectation was a second front in the same war. What followed instead was a grind. Lidl moved 'in fits and starts,' and by mid-2024 it ran only about 170 stores in nine states and DC — having cycled through five different CEOs since opening.⁵ After eight years, it held roughly 1% share in its own trade areas, and its chief executive described the posture as a 'modest pace for now' while the business stabilized.⁶

The point is not that Lidl ran a worse format. The point is that the format was never the asset. By 2017 the US discount aisle Lidl was built to attack was already occupied — by Aldi, by Trader Joe's, by Walmart's own price floor. Lidl arrived with the moves Aldi had spent forty years making, into a market where Aldi had already made them. A discounter's edge is density and trust, and both are slow to manufacture: you cannot buy your way to the corner where shoppers already reflexively turn. Lidl had the playbook. What it didn't have was the head start, and in this business the head start is most of the game.

Wasn't Aldi just early, and Lidl just unlucky with timing?

The fair objection is that this rewards Aldi for being first rather than for being good — that any company arriving in 1976 would have built the same lead, and Lidl's only sin was showing up in 2017. There's truth in it, and timing genuinely matters in a density business. But timing alone doesn't explain the Iowa City failure, the willingness to close rather than compromise the format, or the fact that demand is still accelerating today. In 2024, Aldi's US store visits surged 18.2% over the prior year, and visits per location rose 13.5% — meaning the chain is pulling more traffic into stores that already exist, not just adding boxes.⁹ That is a brand getting stronger on the same footprint, which is what compounding trust looks like decades in. Being early bought Aldi the chance. The operational discipline is what turned the chance into a moat — and it's the discipline, not the calendar, that Lidl couldn't import.

There's a quieter irony buried in the 'two German discounters' story: the two Aldis aren't even one company. The chain that conquered America is specifically Aldi Süd; the other half, Aldi Nord, entered the US separately and runs Trader Joe's, which it acquired in 1979.⁸ The family split the business operationally in 1960, introduced the Aldi name in 1962, and made the two entities legally separate in 1966 — a multi-stage divorce, not a single dramatic break.⁸ The legend says it was a fight over whether to sell cigarettes, but that has never been confirmed by the family or either company, and a German journalist publicly questioned the story in 2009.⁷ Even the origin myth, it turns out, is tidier in the telling than in the record.

Aldi's announced plan is to invest over $9 billion and open 800 new stores by the end of 2028, reaching nearly 3,200 across the country.²³ That is a number only a company sure of its machine would say out loud. It earned that certainty the slow way — one converted building at a time, starting with one in Iowa that didn't work. The lesson everyone draws from market entry is to move fast and plant a flag. Aldi's history says the opposite: in a business where the moat is density and trust, the company that wins is rarely the one that arrives loudest. It's the one that already lives on the corner before you've finished unpacking your playbook.
