A Hedge-Fund Titan’s Divorce Is Putting Wall Street’s Staggering Wealth on Public View

When John Overdeck took the stand as a witness, he didn’t flinch when he mentioned that Laura Overdeck “was able to withdraw $75 million the day before she filed for divorce.” This example is just one of the many staggering sums being bandied about in the divorce trial under way in a New Jersey courthouse. The trial could result in one of the largest divorce settlements ever and shake up the power struggle atop Two Sigma, where John Overdeck has been locked in a bitter feud with his co-founder, David Siegel.

John Overdech has offered Laura $723 million to settle their split. Laura Overdeck says their marital assets should include his stake in Two Sigma, which her attorney estimates the worth to be $6.2 billion. She wants 35% of that, which is $2.17 billion.

On Tuesday, the trial will resume with the cross-examination of John Overdeck. Scheduling conflicts could mean the proceedings drag on for months. 

The major physical asset in the case is the couple’s New Jersey home. 

John Overdeck said in court that he was willing to sell his half of the house to Laura at a value of about $6 million, after retrieving items including: A Stanford crest, a painting of Arundel Castle that hung over the living room sofa and copies from boxes of mementos documenting the children’s firsts.

Other assets discussed at trial include various trusts the couple set up over the years. One was a generation-skipping trust that borrowed money from John Overdeck to purchase interests in Two Sigma.

The fight with the biggest price tag is John Overdeck’s Two Sigma stake.

The sides don’t even agree on how much that is worth, with his lawyers pegging it at $4.9 billion.

Attempts by Laura Overdeck’s counsel to make public Two Sigma’s finances have so far been blocked. Reporters and other observers were asked to clear the courtroom on several occasions so the parties could discuss matters the court had deemed nonpublic.
