Billionaire’s wife challenges £500m divorce offer over Two Sigma fortune
Laura Overdeck, the 56-year-old wife of billionaire hedge fund manager John Overdeck, has returned to court this week after rejecting a $633 million divorce settlement. She claims the offer undervalues her entitlement to the wealth he accumulated through Two Sigma, the Manhattan hedge fund he founded in 2001, just a year before they married without a prenuptial agreement. Her legal team alleges he has deliberately and systematically hidden his assets throughout their marriage to minimise her claim.
The core disagreement centres on the value of John's stake in Two Sigma, which the firm itself is valued at $80 billion. His legal team values his stake at $4.5 billion, whilst Laura's team contends it is worth $6.2 billion and argues she deserves 35 per cent as a marital asset. This week's court hearing marked the 10th day of ongoing proceedings, with portions of testimony from John's financial expert sealed by Judge Bruce Buechler to protect company trade secrets, despite Laura's team questioning the need for secrecy given the valuation had already been publicly discussed.

John Overdeck is a billionaire hedge fund manager who founded Two Sigma in 2001, an investment firm valued at $80 billion. His wife Laura, 56, is seeking a larger share of his wealth in their ongoing divorce after rejecting a settlement offer of around £500 million. They married in 2002 without a prenuptial agreement, which means she has a strong legal claim to assets accumulated during their marriage.
The core dispute centres on the value of John's stake in Two Sigma. His legal team values it at $4.5 billion, whilst Laura's team argues it is worth $6.2 billion and that she should receive 35 per cent as a marital asset.
Divorce cases involving wealthy individuals with privately held companies are complex and often contentious. Determining the true value of a business stake requires expert analysis and can become disputed when one side suspects the other of hiding assets. Without a prenuptial agreement, Laura has a stronger legal position to claim a significant share of the wealth her husband accumulated during their marriage.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Laura's case rests on fundamental fairness principles: she married without a prenuptial agreement and has spent decades building a life with someone who accumulated extraordinary wealth during their marriage. The substantial valuation gap—£1.7 billion between the parties' estimates—suggests either genuine disagreement or, as she alleges, deliberate undervaluation to minimise her entitlement. Her insistence on transparency and full disclosure of assets reflects the reasonable position that spouses deserve accurate information about marital property to secure equitable settlements.
The case against
John's position emphasises that hedge fund valuations are genuinely complex and that his team's £4.5 billion figure may well be sound based on rigorous analysis rather than evasion. He argues that sealing confidential business information protects Two Sigma's legitimate competitive interests—information about strategy, holdings, and valuations can harm any firm if disclosed. The court has mechanisms to ensure fairness whilst protecting trade secrets, and aggressive disclosure demands could set problematic precedent for treating private businesses as transparent as public companies, ultimately harming employees and investors dependent on the fund's success.
