Is Ken Griffin Married? A Look at His Relationships and Family Life

A billionaire, founder and CEO of Citadel, Ken Griffin, is a powerful figure in the world of finance. But what about his personal life? With bold investments, a reputation, and wealth worth billions, many people wonder about his personal side of life. But most importantly, is he married today? Well, the answer might blow your mind. Without further ado, let’s explore his relationship history:

Marriages

Griffin’s personal life, though usually private, has received attention through his high-profile marriage and divorce. Speaking of marriage, he has been married twice.

• Katherine Weingartt

His first marriage was to his high school sweetheart, Katherine Weingart, in 1991. Unfortunately, their union ended in divorce in 1996. This marriage from 1991 to 1996 yielded no public drama or controversy.

• Anne Dias

In 2003, he wed Anne Dias, who is a French-American hedge-fund manager (Aragon Global) and philanthropist. The two met on a blind date in 2002. Thereafter, they quickly became a power couple in Chicago finance and philanthropy. Several years later, they had three children together, born roughly in 2007, 2010, and 2013.

But that’s not all, they also co-founded the Kenneth and Anne Griffin Foundation in 2009 to support early childhood education, the arts, and medical research. During their marriage, the couple donated generously to civic causes. For example, $19 million donation to Chicago’s Art Institute in 2006, where they had their first date. They also donated millions to children’s hospitals.

Lavish Wedding

They married in July 2003 at Chicago’s Fourth Presbyterian Church. It’s a congregation to which he had strong family ties. Afterwards, they had a lavish reception at the Palace of Versailles in France. Both were Harvard alumni, Griffin a 1989 economics grad, Dias a Harvard MBA.

This later inspired his donations to their alma mater, Harvard received a record $150 million gift in 2014. In public, these two often appeared together at cultural and charitable events, reinforcing their image as a giving, high-profile pair.

Divorce Proceedings and Public Disputes

• Filing for Divorce

However, in July 2014, Griffin filed for divorce from Anne Dias, citing irreconcilable differences. The filing, confirmed by their attorneys, took Anne by surprise. Her side later said it was timed to catch her off guard while she was on vacation with the children. The split set off a bitter legal battle over the prenuptial agreement, child custody, and support.

• The Prenuptial Agreement Challenge

Anne challenged the prenup, claiming she had been coerced into signing it on the eve of their wedding and that it was oppressively one-sided. That’s because it was leaving her out of billions of dollars in marital assets. Griffin’s team countered that she had lawyers review the contract well in advance and accepted the terms willingly. One filing bluntly noted she had agreed to the prenup and accepted the promised payments throughout the marriage.

• Media Spotlight and Public Statements

Much of the divorce drama played out in court filings and media coverage. Anne’s lawyers characterized her as having signed under duress and argued for a larger share. However, Griffin insisted he had honored the prenup. Chicago-area media even noted that Anne’s attorney said the divorce petition was filed right as she’d left to take the couple’s children on vacation. As such, she had no time to respond. A Reuters report similarly observed that Anne felt blindsided on vacation.

• Battle Over Child Support and Lifestyle

Meanwhile, financial details became public during the divorce proceedings. Anne’s team reportedly demanded nearly $1 million per month in child support. It included $300,000 for a private jet, $160,000 for vacations, etc., arguing the children were entitled to the lavish lifestyle they had enjoyed.

Griffin’s filings, on the other hand, contested this. He said he had already covered every expense and that his estranged wife simply wanted him to continue funding her lifestyle. A spokesperson for Anne accused Griffin of trying to avoid his financial responsibilities to his family. Griffin’s lawyers, on the other hand, cast Anne’s support requests as attempts to maintain an “opulent” lifestyle.

• Final Settlement

After more than a year of contentious litigation, the Griffins settled the divorce out of court in October 2015. They reached an agreement just hours before a scheduled trial over the prenup. Under the settlement details were private. He paid an estimated $11.75 million to buy out Anne’s share of their Chicago penthouse, and the couple agreed to share joint custody of their three children.

Anne never succeeded in voiding the prenup and received the payouts it stipulated. Observers noted that the divorce should not materially impact Citadel’s business, as Griffin’s assets remained substantial.

Children and Custody

Griffin and Dias-Griffin’s three children, two daughters and a son, were born during their marriage, approximately 2007, 2010, and 2013. Media reports from 2015 listed their ages as about 7, 4, and 2 at the time. Throughout the divorce proceedings, both parents emphasized the children’s well-being.

Anne even sought the right to relocate the children to New York, where her family lives. She highlighted that Griffin had recently bought a $220 million penthouse in Manhattan. In the final settlement, however, the couple agreed to joint custody, meaning the children would split time between each parent’s homes.

The Griffins have otherwise kept the children out of the limelight. There are no known public interviews or appearances featuring the kids. Commentators note that he is particularly protective of family privacy.

Even in divorce filings, the children are referred to only in generic terms by age and not by name. In short, the best-sourced information on the children is that there are three of them, they were toddlers during the split, and they now live with both parents under joint custody.

Current Relationship Status

Since the divorce, Griffin has not remarried, and no credible sources report any public romantic partner. He is now in his mid-50s and appears to live a very private personal life. Media profiles emphasize that he hates publicity and keeps his personal affairs close to the vest, suggesting why little is known about his dating life.

AdviceScout notes that, despite occasional rumors, no reliable information indicates that he is dating anyone. Even Griffin himself has made no public statements about any new relationship. As of 2025, he remains publicly single, focusing on his work and philanthropy. Both he and Anne have since relocated to Florida for business reasons, but they moved there independently, not as a couple.

Philanthropy and Public Image

His relationships, especially his marriage to Anne Dias, have significantly shaped his public image as a philanthropist and power broker. During their marriage, the couple made large gifts together, and their priorities often reflected family interests. For example, Kenneth and Anne co-founded the Kenneth and Anne Griffin Foundation in 2009. It focused on early childhood education, the arts, and medical research, notably women’s and children’s health

They gave $19 million in 2006 to the Art Institute of Chicago’s Modern Wing. It’s a building named in part after the Griffins, which was also the site of their first date. They donated $10 million in 2009 to create a children’s early education center. $16 million donation in 2010 to establish an emergency care center at Lurie Children’s Hospital in Chicago, tying their philanthropy to children’s welfare.

Griffin himself gave $11.5 million in 2011 to build a new chapel at the Fourth Presbyterian Church, where he married Anne. These joint contributions helped cement the Griffins’ image as a powerhouse couple in business and civic life.

After the divorce, Griffin continued to give on a grand scale, though solo. He has become one of the nation’s top donors. Forbes notes he gave over $1.5 billion by 2023. He’s made record-setting donations, e.g. $150 million to Harvard, 2014, and hundreds of millions to Chicago cultural institutions, often spotlighted without reference to family.

These acts influence his public image independently of his personal life. In political circles, his personal networks play a role. He has been a major GOP donor, as was Anne in Illinois politics.

In terms of career impact, the divorce itself appeared to have minimal effect on Citadel or his business reputation. Commentators observed that while the split was one of the most expensive in Chicago history, it had little bearing on Citadel’s performance.

Griffin’s success at Citadel, still a leading global hedge fund, has largely defined his public persona more than his marital status. Still, the divorce did briefly thrust him into the media spotlight, highlighting both the opulent lifestyle of the family and Griffin’s firm stance on the prenup and custody.

Final Remarks

Overall, however, Ken Griffin’s relationships have mainly been seen through the lens of his philanthropy and image as a tech-savvy, self-made billionaire. His former marriage to Anne Dias enhanced his profile as a philanthropic power couple. However, even after divorce, he has maintained privacy, and ongoing civic gifts have kept attention on his professional and charitable achievements rather than any dating life.
