Summary
Ken Griffin, the billionaire founder and CEO of Citadel, one of the world's largest hedge funds, initiated divorce proceedings against his wife Anne Dias Griffin in July following 11 years of marriage. The couple, who met on a blind date through a mutual friend in March 2002 and married in a prominent ceremony at Versailles in France in November 2003, share three children together. The divorce case has been handled through Cook County court and has attracted significant public attention, becoming a top news story.

Anne Dias Griffin is herself a prominent investor and businesswoman, having founded Aragon Global Management, an investment firm, in 2001—prior to meeting Griffin. She holds French-American citizenship. The central point of legal contention in the divorce proceedings centers on the prenuptial agreement executed before the couple's 2003 wedding. Anne Dias Griffin contended in court filings that she encountered substantial difficulty securing independent legal representation to review the prenuptial agreement before signing it. She alleged that dozens of attorneys and their firms declined to represent her due to existing professional relationships with Citadel and Griffin. In response, Griffin's legal filings stated that he had provided her with a draft of the agreement well before she retained counsel and had supplied a list of law firms that had previously represented Citadel, which he characterized as "irrelevant" to her search for family law representation.

According to a representative for the Cook County judge overseeing the case, Griffin and Anne Dias Griffin have now settled their divorce proceedings, concluding the contentious domestic dispute that had thrust the previously private couple into the public spotlight. The settlement marks the resolution of what had become one of the most-followed news stories among financial and general interest audiences.
