The Federal Reserve Inspector General’s September 30, 2026 report found no reasonable grounds for criminal referral or administrative misconduct by former Chair Jerome Powell in the headquarters renovation probe, directly following the Justice Department’s earlier closure of its investigation in April. This outcome stems from scrutiny of Powell’s June 2025 congressional testimony on project costs that exceeded initial estimates by roughly $700 million to reach $2.5 billion, amid broader administration pressure over monetary policy. Trader consensus on related Polymarket contracts reflects the report’s findings, with implied probabilities for federal charges remaining near zero absent new evidence or reopened proceedings. Key upcoming factors include any congressional follow-up or shifts in executive priorities before year-end resolution dates.
