Ken Griffin's lawsuit against the IRS regarding the leak of his confidential tax data to ProPublica was settled in June 2024. As part of the settlement, Griffin agreed to drop his lawsuit, and the IRS issued a public apology for its failure to safeguard his information.
Key Status Updates (as of late 2024–early 2026):
- Dismissal and Settlement: The case was dismissed with prejudice on June 25, 2024, in Florida federal court, meaning it cannot be refiled.
- No Monetary Damages: Griffin did not receive money as part of the settlement; he focused on forcing the IRS to acknowledge its failure and improve security.
- IRS Apology & Action: The IRS apologized for failing to prevent the criminal conduct of contractor Charles Littlejohn, who leaked the data. The agency stated it made "substantial investments in its data security" to strengthen taxpayer data protection.
- Impact on Future Litigation: While Griffin's case resulted in an apology, a separate lawsuit filed by Donald Trump in 2026 over the same leaks seeks $10 billion.
The lawsuit, filed in December 2022, was a response to ProPublica publishing details of tax returns of thousands of wealthy individuals, including Citadel CEO Ken Griffin.
