TL;DR
The U.S. Justice Department is examining whether Iran used Binance to move more than $1 billion through the exchange in ways that may have helped bypass American sanctions. The reported inquiry, based on Wall Street Journal findings, focuses on transactions allegedly tied to networks supporting Iran‑backed militant groups and follows earlier internal reviews that were reportedly halted inside the company.
According to the reports, investigators are looking at whether funds routed through Binance reached entities connected to groups such as Yemen’s Houthis. People familiar with the matter told the WSJ that officials have contacted individuals with knowledge of these transactions to gather evidence. The scope of the probe remains unclear, including whether it targets Binance itself, its users, or both. The renewed scrutiny adds to ongoing concerns about the exchange’s historical exposure to Iranian-linked crypto activity.
The WSJ noted that the DOJ’s inquiry follows earlier reporting that Binance dismantled an internal investigation into roughly $1 billion flowing through the platform to a network tied to Iranian proxy groups. Binance has denied claims that it fired investigators working on these issues, calling previous reports inaccurate. The exchange also pushed back this week against a separate U.S. Senate probe, arguing that the investigation relied on what it described as demonstrably false reporting.

Regulatory pressure on Binance has been building. A federal judge recently dismissed a lawsuit alleging the exchange helped finance terrorism through crypto transactions, though the plaintiffs may refile with revised claims. Binance has repeatedly denied wrongdoing. The company previously pleaded guilty in 2023 to violating U.S. anti-money-laundering and sanctions laws, paying a $4.3 billion fine and agreeing to operate under U.S. oversight. Former CEO Changpeng “CZ” Zhao also pleaded guilty and later received a presidential pardon in 2025.
The investigation comes as analysts and policymakers examine Iran’s use of digital assets to navigate financial restrictions. Blockchain analytics firms have reported shifts in Iranian crypto activity during periods of geopolitical tension. Recent Chainalysis data showed rising outflows after regional airstrikes, while TRM Labs research found Iran’s crypto ecosystem remains structurally resilient despite declining trading volumes.
