U.S. federal prosecutors are examining whether cryptocurrency exchange Binance failed to stop trading activities that violated American sanctions against Iran. The inquiry is being handled by the Manhattan U.S. attorney's office with involvement from the Justice Department's criminal division in Washington. Authorities are specifically scrutinizing whether the platform knowingly permitted these transactions, though the exact nature of the trades under review remains unclear. Spokespeople for both the Justice Department and the Manhattan U.S. attorney's office declined to comment on the ongoing investigation.

This probe follows a history of regulatory friction for Binance, which pleaded guilty nearly three years ago to failing to comply with U.S. banking and sanctions laws. In that settlement, the company paid $4.3 billion, accepted two corporate monitors, and saw co-founder Changpeng Zhao step down as CEO before serving four months in prison and receiving a presidential pardon last year. Recent reports from Fortune and the Wall Street Journal alleged that internal investigators found over $1 billion moving through the platform to Iran-linked entities before being dismissed, while the New York Times cited a figure of $1.7 billion. Senator Richard Blumenthal subsequently opened a preliminary inquiry demanding records on entities named Hexa Whale and Blessed Trust. Binance has rejected these accounts, stating that at most $126.1 million reached wallets linked to Iran after multiple hops, with no more than $24.1 million reaching IRGC-related wallets. The exchange maintains it cooperates with law enforcement and enforces a zero-tolerance policy for sanctions violations.
