John Catsimatidis Net Worth

John Catsimatidis has an estimated net worth of $6.2 billion, according to Forbes Real-Time Billionaires, John Catsimatidis profile (figures as of October 20, 2026). That is up from $3.1 billion in 2019.

John Catsimatidis is an American businessman best known for owning the New York City supermarket chain Gristedes. He also leads D'Agostino Supermarkets in Manhattan, the Red Apple Group, and United Refining Company. His career started in grocery stores while he was attending New York University. He left school for a chance to own part of the shop where he worked, then built his own chain through Red Apple stores and later bigger deals.

His wealth comes mainly from oil and real estate, along with his long-running supermarket business. He opened his own grocery store in 1969 and had 10 Red Apple stores by age 25. In 1986, Red Apple bought 36 Gristedes supermarkets and 11 Charles & Co. specialty-food stores. That same year, he acquired United Refining. Forbes says his net worth is $6.2 billion on its real-time billionaires tracker as of October 20, 2026.

How John Catsimatidis built his business

Catsimatidis made his name in food retail. He started as a grocery clerk, then got the chance to buy into the small supermarket where he worked. After opening his own store, he expanded Red Apple by keeping stores open late, offering free delivery, and cashing checks for customers. By the summer of 1981, Red Apple had 27 stores in the Bronx and Manhattan, and sales later reached $110 million in 1985.

He expanded far beyond supermarkets. Red Apple bought Gristedes in 1986, giving him a bigger place in New York grocery retail. He also bought United Refining out of bankruptcy and built a second major business in energy. Forbes ties his fortune to oil and real estate, and his holdings also include property in New York and other states. He later moved into radio, with talk shows and the purchase of WABC that closed in March 2020.

Where his money comes from now

Today, Catsimatidis is known for a mix of supermarkets, energy, real estate, aviation, and radio. He is the owner, president, chairman, and CEO of Gristedes and D'Agostino Supermarkets, and he leads the Red Apple Group. He is also chairman and CEO of United Refining Company. Forbes places him in the energy industry, which fits the size of his refining business and his oil-related assets alongside property holdings.

Forbes has tracked a steady rise in recent years, from $3.1 billion in 2019 to $4.8 billion in 2026 on its annual billionaires lists. On Forbes' real-time tracker, that estimate reached $6.2 billion in October 2026. The businesses behind that estimate are consistent across his career: supermarkets, United Refining in Pennsylvania, and real estate in New York and beyond. He is also listed by Forbes as self-made.
