History

Historical Context

Senator Joe Lieberman introduced the STOCK Act on Jan 26 2012; after only three senators opposed, President Barack Obama signed it on Apr 4 2012, requiring lawmakers to disclose trades within 45 days. The 2020 insider-trading scandal exposed gaps, and today the Senate’s unanimous ban on federal prediction-market trading builds on that transparency push.
