You have probably grabbed a bag of chips, a carton of eggs, or a bottle of olive oil at Aldi without thinking twice about who actually owns the store. The prices were low, the checkout was fast, and the whole experience was oddly satisfying. But behind those no-frills shelves and private-label products is one of the most remarkable — and most secretive — family business stories in modern history.
Aldi is owned by the Albrecht family of Germany. Two brothers who inherited a small grocery store from their mother after World War II turned it into a $155 billion global retail empire that today operates nearly 14,000 stores across 18 countries. Neither brother ever gave a public interview. One was kidnapped for ransom. And the family that runs it today is worth tens of billions of dollars — and almost nobody knows their names.
What Is Aldi?
Aldi is a chain of supermarkets known for its discount model. The chain was founded by brothers Karl and Theo Albrecht in 1946, when they took over their mother’s store in Essen, Germany. The business was split into two separate groups in 1960 that later became Aldi Nord (North) and Aldi Süd (South).
Aldi’s two divisions — Aldi Süd and Aldi Nord — continued to pursue rapid expansion outside their European home markets in 2025, with the U.S., U.K., and Australia all being major growth priorities.
Aldi’s 2024 total company revenues were $155.1 billion, and it operates 13,877 stores in 18 countries. 65.1% of Aldi’s 2024 revenue came from international sales. That makes Aldi the second-largest grocery retailer in the world by revenue.
Who Owns Aldi Right Now in 2026?
Aldi is a 100% privately held company. It does not trade on any stock exchange, and it does not publish detailed financial reports. Ownership is split between two separate family groups — one controlling Aldi Nord and the other controlling Aldi Süd.
Aldi Nord is owned by three private family foundations: Markus-Stiftung, Jacobus-Stiftung, and Lukas-Stiftung, which together hold 100% of the company under a structure known as a Doppelstiftungsmodell (dual-foundation ownership model). These foundations are based in Nortorf, Schleswig-Holstein. The foundations’ assets include Aldi Nord’s operations in Germany, as well as international subsidiaries in Belgium, France, Luxembourg, the Netherlands, Poland, Portugal, and Spain, and ownership of Trader Joe’s in the United States.
Aldi South’s ownership is now controlled by Karl’s heirs, including his son, Karl Jr., and daughter, Beate Heister.
In simple terms: Aldi Nord belongs to the Theo Albrecht side of the family, and Aldi Süd belongs to the Karl Albrecht side. The two halves of the business are financially and legally completely separate from each other, despite sharing the same name and the same roots.

The Origin Story: A Mother’s Shop, Two Sons, and a World-Changing Idea
The story of Aldi begins not with billionaires or boardrooms, but with a woman named Anna Siepmann Albrecht and a small grocery shop in Essen, Germany.
Aldi’s roots trace back to matriarch Anna Siepmann Albrecht, who opened a small grocery store in a suburb of Essen, which is in western Germany, in 1913. Anna’s husband Karl Albrecht was a miner, and the couple had two sons, Theodor Paul (also known as Theo) and Karl Hans.
Karl and Theo were born in 1920 and 1922, respectively. Theo Albrecht completed an apprenticeship in his mother’s store. In 1945, the brothers took over their mother’s business and soon opened another retail outlet nearby. By 1950, the Albrecht brothers owned 13 stores in the Ruhr Valley.
Their core idea was radical for the time. Rather than offering a wide variety of products, they cut their range to only the most popular items, stripped out all advertising, kept stores small and simple, and passed every single cost saving directly to the customer in the form of lower prices. In 1962, they introduced the name Aldi — a syllabic abbreviation for “Albrecht Diskont.”
By 1960, 300 stores were operating across Germany. The brothers had built something extraordinary — and then they split it in two.
The Famous Split: Why Aldi Became Two Companies
The brothers split the company in 1960, reportedly over a dispute about whether they should sell cigarettes. Karl believed they would attract shoplifters, while his brother Theo did not.
The result was that Theo took the northern stores — creating Aldi Nord — and Karl took the southern stores — creating Aldi Süd. In Germany, Aldi Nord and Aldi Süd have been financially and legally separate since 1966, although both divisions’ names may appear as if they were a single enterprise when dealing with certain store brands or when negotiating with contractors.
This split is why Aldi in the United States is actually operated by Aldi Süd, while Trader Joe’s — which looks nothing like Aldi — is actually owned by Aldi Nord. Two different branches of the same family, running two completely different retail empires, both tracing back to a single small shop in Essen.
Aldi Comes to America — and Buys Trader Joe’s
In 1968, Aldi South embarked on international operations with its first store outside Germany in neighboring Austria. In 1976, it entered the U.S. market with its first store in Iowa, and it later set up its headquarters in Batavia, Illinois. As of January 2026, Aldi operated more than 2,400 stores in 38 states with more than 45,000 employees.
Meanwhile, the Aldi Nord side of the family made an equally significant move in America. In 1979, Aldi North, under Theodor Albrecht, bought Trader Joe’s and maintained the same concept envisioned by founder Joe Coulombe: a niche neighborhood grocery store offering quality food products at reasonable prices. By early 2026, Trader Joe’s reportedly had more than 600 stores across the U.S.
So when you shop at Aldi and then walk into a Trader Joe’s — you are patronizing two grocery chains both ultimately owned by two branches of the same German family, whose roots go back to a single store opened by a woman named Anna Albrecht in 1913.
The Albrecht Family: Secretive, Frugal, and Extraordinarily Wealthy
The Albrecht brothers were famously reclusive. Theo was rarely pictured by photographers and never made a public statement. The last published photo of Theo Albrecht dates from 1971, one day after his kidnapping.
That kidnapping is one of the most dramatic episodes in German business history. In 1971, Theo Albrecht was kidnapped. A ransom of seven million German marks (approximately $2 million at the time) was paid for his release. He was held for seventeen days and later unsuccessfully claimed the ransom as a tax-deductible business expense in court.
After the kidnapping, both brothers became even more withdrawn from public life, driving armored cars and refusing virtually all public contact.
Karl Albrecht Jr., son of the elder Karl, and his family have a combined net worth of $16.3 billion as of January 2026, according to Forbes. His sister, Beate Heister, also has a net worth of $16.3 billion. Theodore Jr., son of Theodor, and his family have a combined net worth of $16.2 billion as of January 2026.
Karl Albrecht Sr. passed away in 2014 at the age of 95 with an estimated net worth of $25.9 billion. Theo Albrecht died in 2010 at the age of 88.
Aldi’s U.S. Expansion: America’s Fastest-Growing Grocer
Aldi has cemented itself as America’s fastest-growing grocer, now the third-largest by store count, serving millions of customers each month. In 2024, the retailer opened nearly 120 locations, bringing its total U.S. footprint to more than 2,400 stores — and 2025 is set to be a record-breaker, with plans to open over 225 new stores as part of a five-year expansion goal to reach 800 additional stores by 2028.
Twenty-five percent of U.S. customers now shop at Aldi — double the share from just six years ago. The company’s formula is working: keep prices low, keep the product range tight, use private labels almost exclusively, and let the quality speak for itself.
