Born 1948. John Catsimatidis is an American and Greek businessperson and politician.

John A. Catsimatidis ( ; born September 7, 1948) is an American billionaire businessman, radio talk show host, and actor. He is the owner, president, chairman, and CEO of grocery chains Gristedes and D'Agostino Supermarkets in Manhattan, as well as the Red Apple Group, a real estate and aviation company with about $2 billion in holdings in New York, Florida and Pennsylvania. He is also the chairman and CEO of the Red Apple Group subsidiary United Refining Company.

Catsimatidis hosts two talk radio shows, The Cats Roundtable on WABC and the Cats at Night show. He initiated purchase talks for the WABC radio station in 2019 which, after regulatory delays, was concluded in March 2020.

Catsimatidis was the runner-up in the Republican nomination for mayor of New York City in the 2013 election.

Early life Catsimatidis was born on the Greek island of Nisyros on September 7, 1948. He came to the United States with his parents when he was six months old. The family moved to West Harlem, where Catsimatidis grew up. Catsimatidis's father had been a lighthouse operator in Greece but worked as a busboy in New York. Catsimatidis graduated from Brooklyn Technical High School in 1966. He received a congressional nomination to West Point, but chose to study electrical engineering at New York University instead.

While in college, Catsimatidis worked for the uncle of a friend, Tony, in a small supermarket on 137th Street which Tony and his uncle owned. While Catsimatidis was still in college, Tony sold his half of the store to Catsimatidis. Shortly thereafter, he purchased another grocery store on 87th street just west of Broadway, naming it Red Apple. Among his business innovations were keeping stores open late seven days a week, offering free delivery, and cashing checks for customers. However, United Refining Energy Corp. shareholders did not approve the deal and it was terminated in December 2009. Catsimatidis is the chairman and CEO of United Refining Co., which is a subsidiary of the Red Apple Group.

In 2008, Catsimatidis became engaged in efforts to take over SemGroup LP, a bankrupt oil, gas, and asphalt trading, storage and transportation company, headquartered in Tulsa, Oklahoma. Catsimatidis gained control over a majority of the company's management committee, but his efforts were met by opposition from the company's existing management, who argued for selling off at least some of the company's assets, while Catsimatidis wanted to keep the company together. In February 2009, Catsimatidis was sued by a group of SemGroup executives, who sought the removal of Catsimatidis and his allies from the committee. In July Catsimatidis reached a settlement with SemGroup, pursuant to which he acquired a piece of SemGroup's asphalt business and dropped his competing plan for the company's proposed reorganization.

In 2015, the Red Apple Group ranked 156th on Forbes magazine's list of "America's largest private companies", with revenue of $3 billion and 8,000 employees. (This compares to its 2008 and 2009 rank, both at 100th, 2010 at 78th, 2011 at 98th, and 2012 at 97th).

Catsimatidis shared his rags-to-riches story in his memoir How Far Do You Want to Go?: Lessons from a Common-Sense Billionaire, published by Matt Holt in February 2023.

In 2019, he announced an agreement to purchase WABC for $12.5 million, which, after regulatory delays, was finalized in March 2020. and WLIR.

Catsimatidis has been described as a "longtime", "loyal", and "high-level Clinton donor". Catsimatidis donated a significant sum to the Clinton Presidential Center, thought to be between $100,000 and $500,000. Catsimatidis was a member of Hillary Clinton's finance team during her 2008 campaign for the Democratic presidential nomination, saying in February 2007 of Clinton, "She's unstoppable. She's got such a machine."

Politics 2009 mayoral campaign A donor to Bill Clinton during the Clinton years, Catsimatidis, while still enrolled as a Democrat, considered becoming a candidate in the 2009 mayoral election as a Republican. In May 2007, he was reported to be "systematically wooing local Republicans", attending various Republican fundraisers in Queens and Staten Island and stating that he would "probably have a press conference" to announce his intentions "sooner rather than later" and would consider spending between $30 million and $40 million if he ran. By July 2008, Catsimatidis formed an exploratory committee. In 2009, Catsimatidis spent nearly $300,000, much of it on polls and consultants, to explore a candidacy. He said he only agreed to drop out after Bloomberg informed him of his plans to seek a third term.

In December 2012, Catsimatidis established an exploratory committee to consider running for mayor.

Catsimatidis made his official announcement on January 29, 2013, vowing to be "a leader for Harlem and Wall Street." He stated "I'm not a Mike Bloomberg billionaire. I'm not wearing a $5,000 suit." Through May 15, Catsimatidis (a self-financed candidate) had spent $880,000 on the campaign, mostly on television and radio ads, but also on billboards and items including lip balm and groceries. He hired a campaign consulting firm, Millennial Strategies LLC, that mostly works on Democratic campaigns.

On a December 13 appearance on Inside City Hall, Catsimatidis compared raising taxes on the wealthy to how "Hitler punished the Jews".

Catsimatidis expressed support for the New York City stop-and-frisk program, and two weeks after the Boston Marathon bombing, his campaign ran a radio ad attacking "career politicians want to end stop and frisk and cut the NYPD's powers of surveillance." At a candidates' forum Catsimatidis suggested that "a robot" or other future technology would make the stop-and-frisk program unnecessary in the future, but stated that until that time the program should continue.

At campaign events in April 2013, Catsimatidis claimed that he could have beaten Barack Obama in the 2012 presidential election and got into a contentious exchange with various Republican audience members, telling one to "go bullshit yourself if you want!"

Catsimatidis said he considered running in the 2021 New York City mayoral election. He originally suggested he'd run as a Democrat, but retracted that and suggested he would either run again as a Republican or as a member of the Liberal Party.

Catsimatidis told the Washington Examiner in April 2023 that he was ruling out supporting Florida governor Ron DeSantis in the 2024 Republican Party presidential primaries, due to the latter not returning his phone calls.

On April 24, 2024, in an interview with Steve Bannon, Catsimatidis hinted at a potential run in the 2025 New York City mayoral election. He spoke about law and order, and proposed to clean up the streets in 60 days. He also said he would pressure the president of Columbia University to stop pro-Palestinian protesters, and supported nuclear energy. On March 7, 2025, in an interview on WABC radio's Sid & Friends in the Morning, Catsimatidis dismissed speculation that he would be running for mayor, saying "I don't think I'll run", but when asked if he would run in the 2026 New York gubernatorial election, he said "you never know what can happen." During the 2025 New York City mayoral election, Catsimatidis threatened to move his stores from New York to New Jersey if Zohran Mamdani won the election. After Mamdani won the election, Catsimatidis said he was reconsidering moving.
