(Bloomberg) -- Billionaire Ken Griffin is reaching a tipping point with Chicago, the home to his market maker and hedge fund business, as the city wrestles with rising crime. 

“We’re getting to the point that if things don’t change, we’re gone,” Griffin, who runs both the hedge fund Citadel and the market-making business Citadel Securities, said Thursday in an interview. “Things aren’t changing.” 

Griffin’s businesses currently count South Dearborn Street in Chicago as its headquarters, just a few blocks from the Willis Tower and close to Millennium Park. He’s long hinted that he would consider relocating the firm amid growing frustrations with violence and political leadership in Illinois. The Citadel founder has been a vocal advocate of public safety measures, calling some of the violence “senseless” as he announced a $25 million donation to help finance a University of Chicago Crime Lab’s new program on policing and public safety training.

Citadel has been seeking more office space in Manhattan, as it plans on growing its employee base in the city, Bloomberg reported in February. The firm, which already has several locations in New York, has been in talks to lease even more space in Midtown. One of those locations is expanding at 425 Park Ave., where Citadel signed on as an anchor tenant before the pandemic started. The firm also occupies space in Florida and has been looking to expand in that state. 

Griffin, who has a net worth of $29.7 billion, founded Citadel in 1990, and the hedge fund now has about $51 billion in investment capital. He later established Citadel Securities, the market maker that serves asset managers, banks, broker-dealers, hedge funds, government agencies and public pension programs.

The billionaire has been giving millions of dollars to Illinois’ Republican gubernatorial candidate Richard Irvin, the mayor of the state’s second-largest city Aurora. Irvin is working to unseat Governor J.B. Pritzker, a Democrat seeking a second term. 

“My patience is wearing thin,” Griffin said Thursday, citing an incident he witnessed outside his office this past weekend.
