John Overdeck faces a divorce battle and a feud with his Two Sigma co-founder

The Wall Street Journal reports that billionaire John Overdeck faces a court battle with his estranged wife, Laura, over whether his $723 million divorce settlement offer is fair. He is also at odds with Two Sigma co-founder David Siegel over the firm’s direction and control. Overdeck objected to Laura’s lawyers’ push to make company records public, fearing their release could give Siegel ammunition in their feud.
