On January 10, it was reported that after a long dispute over the direction of Two Sigma Investments's development, John Overdeck and David Siegel, the two founders of the quantitative giant, entered arbitration proceedings. Two Sigma disclosed the arbitration incident in a letter to investors on the 8th local time. People familiar with the matter revealed that the company stated in the letter that it is not a party to the dispute and does not plan to regularly share relevant updates with customers. A Two Sigma spokesperson said in a statement: “Although arbitration proceedings are ongoing between the company's founders, the management team remains focused on serving our investors and strengthening Two Sigma for long-term development.” The company did not elaborate on the details of the arbitration dispute. Overdeck's relationship with Siegel used to be so unhappy that Two Sigma listed the discord between the two as a major risk in the March 2023 regulatory filing. In August of last year, the company announced that they would both withdraw from daily management, continue to serve as co-chairman, and provide advice on quantitative investment and technology issues, while maintaining their shareholding.
