Current Context

The criminal probe into Jerome Powell closed but remains potentially reversible. The Department of Justice (DOJ) announced on April 24, 2026, the closure of its criminal investigation into Federal Reserve Chair Jerome Powell, referring the matter to the Federal Reserve's Inspector General [^][^][^][^][^][^]. Initiated in November 2025, the probe investigated whether Powell made false or misleading statements to Congress regarding the scope and $2.5 billion cost of the Federal Reserve's headquarters renovation [^][^][^][^]. However, U.S. Attorney for the District of Columbia, Jeanine Pirro, indicated that her office could reopen the investigation depending on the findings of an ongoing review by the Federal Reserve's Inspector General [^][^][^][^][^][^][^]. Pirro also plans to appeal a federal judge's decision from March 2026 that quashed subpoenas issued in the initial investigation, with the judge ruling that the government had offered "essentially zero evidence" of a crime and that the subpoenas were intended to "harass and pressure" Powell [^][^][^][^][^].
The investigation had political implications for succession and Powell's tenure. The probe was widely seen as politically motivated, stemming from a long-running conflict between President Donald Trump and Powell over interest rates [^][^][^][^][^][^][^][^]. Critics, including several Republican senators and former Fed chairs, condemned the probe as an attempt to undermine the Federal Reserve's independence [^][^][^]. The closure of the investigation cleared a significant obstacle for the confirmation of Kevin Warsh, President Trump's nominee to succeed Powell, as Senator Thom Tillis had previously blocked Warsh's nomination insisting the investigation be resolved first [^][^][^][^][^][^][^][^]. While Powell's term as Chair was scheduled to end on May 15, 2026 [^][^][^][^], he announced his intention to remain on the Fed's Board of Governors until his term as governor expires in January 2028, citing "legal attacks" against the central bank and expressing confidence in no further DOJ action [^][^][^][^][^][^]. As of early May 2026, prediction markets indicated a high probability (around 97.4% to 98.2%) of Powell's departure as Fed Chair by May 31, 2026, reflecting the removal of legal hurdles for Warsh's confirmation [^][^][^].

2. Market Behavior & Price Dynamics

Historical Price (Probability)

Outcome probability
Date
This prediction market displays a sideways trend, with the probability of the DOJ reopening its investigation into Jerome Powell trading in a very tight range between 2.0% and 4.0%. The market opened at 3.0% following the April 24, 2026 announcement that the DOJ had closed its criminal probe. The price subsequently drifted down to its current level of 2.0%. This price action indicates that the market has fully priced in the closure of the investigation, assigning an extremely low probability to its reopening. The lack of significant price movement suggests no new information has emerged to alter this assessment.
Trading volume has been relatively light, with a total of 7,407 contracts traded. A significant portion of this activity occurred early in the market's history, suggesting traders established their positions shortly after the DOJ's announcement and have seen little reason to change them since. The 2.0% level appears to be acting as a strong support floor, while 4.0% has served as resistance. Overall, the chart reflects a strong and stable market consensus. The consistent, low price suggests participants have very little conviction that the investigation will be revived, viewing its closure as a likely final development.

Market Discussion

The Department of Justice closed its criminal investigation into Jerome Powell in late April 2026, referring the matter to the Fed Inspector General and noting that a restart is contingent on the Inspector General’s findings [^][^][^]. US Attorney Jeanine Pirro said on 2026-05-03 that she may reopen a criminal investigation into Powell depending on that report [^]. Prediction markets show low probabilities for an imminent reopening, with "June 30" at approximately 9% and "May 15" at approximately 4% as of 2026-05-04 [^].

4. What specific findings in the Federal Reserve Inspector General's review could compel the DOJ to reopen its investigation into Jerome Powell?

IG Review FindingNo wrongdoing found in headquarters renovation cost overruns [^][^][^]
DOJ Reopening ConditionRequires evidence of crime (e.g., fraud, misleading testimony) from IG probe [^][^]
Current Reopening LikelihoodFacts do not currently specify findings that compel DOJ to reopen investigation [^][^][^]
The Federal Reserve Inspector General found no wrongdoing in renovation overruns. The Inspector General's review into the Federal Reserve headquarters renovation cost overruns concluded that there was no criminal conduct [^][^][^]. This finding significantly weakens any argument for the Department of Justice (DOJ) to reopen its investigation based on new, Inspector General-confirmed criminal conduct [^][^][^].
DOJ would only reopen if evidence of a crime emerged. US Attorney Jeanine Pirro indicated that the DOJ would not rule out restarting an investigation if the Inspector General's probe uncovered facts warranting such action [^][^]. However, the decision to reopen an investigation is contingent on the Inspector General providing evidence of a crime, such as fraud or misleading testimony, rather than merely cost overruns [^][^]. Given the reported findings of no wrongdoing, the current facts do not present any specific findings from the review that would compel the DOJ to reopen its investigation [^][^][^].

5. What is the legal threshold the DOJ must meet to reopen its criminal investigation into Powell, and what precedents apply?

Legal Threshold to ReopenAn “articulable factual basis” that a federal crime is or may be occurring [^][^]
Standard Compared to Probable CauseSubstantially lower than probable cause [^][^]
Original Investigation Closure DateLate April 2026 [^]
The Department of Justice can reopen investigations with a lower legal threshold. To restart a criminal investigation into Powell, the Department of Justice (DOJ) requires an “articulable factual basis” indicating that a federal crime is or may be occurring [^][^]. This legal standard, which also applies to FBI investigative predication for a full investigation, is described as “substantially lower than probable cause” [^][^]. The decision to reopen an investigation is an investigative step governed by investigatory predication and is not constrained by trial-stage constitutional doctrines such as double jeopardy [^]. Double jeopardy, which typically prevents second trials after an adjudication, does not apply here because reopening an investigation is an investigative step that precedes any charging decision [^].
DOJ kept Powell investigation open for potential future action. Although the DOJ closed its criminal investigation of Powell in late April 2026, the possibility of restarting the inquiry was explicitly left open should the Inspector General’s findings necessitate further action [^]. Furthermore, the US attorney has not ruled out the continuation of investigations into Federal Reserve Chair Powell [^].

6. How does U.S. Attorney Jeanine Pirro's public rationale for potentially reopening the case contrast with the federal judge's ruling quashing the initial subpoenas?

Pirro's Statement on Reopening InvestigationDepends on inspector general's findings (May 3, 2026 CNN) [^]
Judge's Ruling on DOJ SubpoenasQuashed subpoenas in March 2026 [^]
Judge's Reason for Quashing"Essentially zero evidence" of a crime; improper purpose (harassment/pressure) [^]
U.S. Attorney Jeanine Pirro's potential reopening of a probe hinges on an inspector general's report. Her public rationale for potentially reopening a criminal investigation into Federal Reserve Chair Jerome Powell is directly contingent on the findings of an upcoming inspector general's report [^]. On May 3, 2026, Pirro publicly stated on CNN that her decision to continue the probe into Powell "depends on what [the inspector general] finds," indicating she would "go home" if nothing substantial was uncovered [^]. She also affirmed that the Department of Justice intends to continue litigating and appeal the original subpoena ruling [^].
A federal judge previously quashed subpoenas, citing "zero evidence" and improper motives. This stance contrasts sharply with a federal judge's earlier ruling in March 2026, when Judge James Boasberg quashed grand-jury subpoenas issued by the DOJ to Powell and the Federal Reserve [^]. Judge Boasberg determined that the government had presented "essentially zero evidence" of a crime [^]. Furthermore, the judge found that the subpoenas' "dominant (if not sole) purpose" was to harass and pressure Powell into resigning or complying with political demands, thereby indicating an improper motive rather than legitimate evidentiary justification [^][^]. This significant distinction suggests that any future reopening of the investigation by the DOJ would necessitate substantially new and independent findings, aligning with Pirro's stated reliance on the inspector general's report for further action [^][^].

7. What is the expected public release timeline for the Federal Reserve Inspector General's report, and how does it align with the market's 2026-2027 resolution dates?

DOJ Referral to FRIGApril 24-25, 2026 [^][^][^][^][^][^]
Renovation Project Completion2027 [^]
FRIG Report Public Release TimelineNot announced [^]
The Federal Reserve Inspector General (FRIG) has not announced its report timeline. The FRIG has not specified a public release timeline for its report concerning the renovation project [^]. Findings from this investigation are set to be made public and shared with Congress once the report is completed [^][^]. The Department of Justice (DOJ) ceased its criminal investigation into Powell and referred the matter to the FRIG on April 24-25, 2026 [^][^][^][^][^][^]. U.S. Attorney Jeanine Pirro, who initiated the DOJ probe, stated her office is prepared to restart a criminal investigation if facts from the FRIG's findings warrant such action [^][^][^][^][^].
Market resolution dates precede the project's completion in 2027. While the FRIG report's public release date remains unannounced [^], the renovation project itself is scheduled to conclude in 2027 [^]. Prediction markets for the question "Will the DOJ reopen its investigation into Powell?" have various resolution dates, some by May 15, 2026, and others by June 30, 2026 [^]. The overarching event is expected to close around June 30, 2026 [^]. Given the lack of a specific public release timeline for the FRIG's report, its alignment with these 2026 market resolution dates is currently unclear [^][^].

8. What actions from President Trump's administration could signal renewed pressure on the DOJ to act against Powell before January 2027?

Trump's Public Statement DateFebruary 3, 2026 [^]
DOJ Investigation StatusClosed in April 2026, possibility of restart [^][^][^]
D.C. U.S. Attorney Statement DateMay 3, 2026 [^][^]
A future Trump administration could signal renewed pressure on the Department of Justice (DOJ) to act against Jerome Powell through public statements. This would build upon a pattern where White House pressure has previously translated into DOJ investigative action [^][^][^][^]. For example, President Trump publicly indicated on February 3, 2026, that he wanted the DOJ probe to continue "to the end and see" [^]. While the DOJ subsequently closed its direct criminal investigation into Powell in April 2026, it explicitly created a mechanism for potential reopening [^][^][^].
The DOJ's conditional closure created a clear pathway for reopening the probe. In April 2026, the Department of Justice closed its criminal investigation into Jerome Powell [^][^][^], but critically shifted its scrutiny to the Federal Reserve inspector general and left open the possibility of restarting criminal action after this review [^][^][^]. This directly established a "reopen trigger" mechanism. On May 3, 2026, D.C. U.S. Attorney Jeanine Pirro stated she might restart a criminal investigation into Fed Chair Powell, depending on what the Fed inspector general's review of Fed renovation cost overruns uncovers [^][^]. Therefore, any actions from a future Trump administration that highlight, push for, or publicly comment on the findings of this Fed inspector general’s review could signal renewed pressure on the DOJ, leveraging this directly stated conditional pathway [^][^]. The initial probe in January 2026, which followed Trump pressure and escalated to grand jury subpoenas, establishes a precedent for White House influence translating into renewed DOJ investigative pressure [^][^][^].

9. What Could Change the Odds

Key Catalysts

An investigation initiated in late 2025 under the Trump administration focused on the renovation of the Federal Reserve's headquarters and Powell's congressional testimony regarding the project [^] [^] [^] [^] [^] [^] . The probe was widely perceived as politically motivated, an effort to pressure Powell into lowering interest rates, and was criticized for a lack of evidence [^][^][^][^][^][^][^].
A federal judge even quashed subpoenas related to the investigation, deeming them an attempt to "harass and pressure Powell" [^] [^] [^] [^] [^] . Upon closing the investigation, U.S. Attorney for the District of Columbia Jeanine Pirro stated that her office would not hesitate to restart a criminal investigation "should the facts warrant doing so," with the Federal Reserve's Inspector General now scrutinizing the renovation project [^][^][^][^][^][^].
