A contentious divorce trial has begun in New Jersey, where billionaire hedge fund manager John Overdeck is accused by his estranged wife's legal team of systematically planning for years to diminish her share of his estimated $8 billion fortune.
Laura Overdeck's lawyers claim that John Overdeck, 56, "methodically and strategically" worked for decades to secure his wealth in anticipation of a divorce, aiming to leave her with as little as possible. They contend that a proposed $633 million settlement is insufficient, arguing she is entitled to a larger portion of his stake in their firm, Two Sigma.
John Overdeck's legal team, however, stated that he is prepared to offer his estranged wife $723 million in tax-free cash. The primary dispute centers on whether Laura Overdeck is entitled to a greater share of the value of John Overdeck's stake in Two Sigma. Her lawyers are seeking 35 percent of his stake, which they estimate to be worth $6.2 billion, while his lawyers place the figure at $4.9 billion.
John Overdeck's legal counsel, Jonathan Wolfe, argued that Two Sigma, which he co-founded, is not a marital asset. He asserted that the firm was established two years before the couple's marriage in 2002 and had already managed substantial assets and done significant work prior to their union. According to Forbes, Overdeck has a net worth of $8 billion.
Therese Lyons, Laura Overdeck's lawyer, countered that at the time of their marriage, Two Sigma was merely a concept and only began active trading afterward. She accused John Overdeck of "working tirelessly" to hide assets from his wife and "planning his escape" during their marriage, orchestrating a scheme to strip billions from their marital estate.
John Overdeck testified that he grew Two Sigma from under $1 billion in 2001 to its current valuation of $80 billion. His lawyers pointed out that he earned $685 million during their marriage, all of which was deposited into a joint bank account, and that he had amassed billions prior to their marriage.
Before co-founding Two Sigma with David Siegel, Overdeck worked at DE Shaw & Co. and assisted Jeff Bezos in launching Amazon. His lawyers contend that the $723 million offer is "more than enough to meet the needs of the parties' marital lifestyle."
Beyond the cash settlement, Laura Overdeck is also seeking hundreds of millions in treasury bonds held in a trust. She is further requesting joint control of their family foundation or, failing that, 50 percent of its value to be allocated to a charity of her choice. Publicly available tax filings from 2024 indicate the foundation holds approximately $920 million in assets.
Laura Overdeck holds a degree in astrophysics from Princeton University and an MBA from the Wharton School of Business. She is also the founder and overseer of the nonprofit organization Bedtime Math, which aims to help parents teach mathematics to their children. The trial is taking place before New Jersey Superior Court Judge Bruce Buechler.
