The DOJ's criminal probe into former Fed Chair Jerome Powell, centered on headquarters renovation cost overruns exceeding $2.5 billion and related congressional testimony from 2025, was formally closed on April 24, 2026, after a federal judge quashed grand jury subpoenas for insufficient evidence beyond policy disputes. No indictment materialized despite January 2026 subpoenas, and Powell's term ended in May with his move to a board seat, eliminating ongoing prosecutorial leverage. Trader sentiment on related Polymarket contracts reflects this resolution alongside the absence of new referrals, IG findings, or congressional actions, pricing in negligible implied probability of federal charges absent unexpected political shifts. Key benchmarks include the Fed funds rate path and Treasury yields, which remain decoupled from the episode. No material catalysts are scheduled before year-end.
