DOJ Probes Iran's Use of Binance to Dodge Sanctions

The DOJ is investigating whether Iran used Binance to evade U.S. sanctions — and the probe is moving fast. Federal officials have begun reaching out to people with knowledge of transactions that allegedly funneled more than $1 billion through the exchange to Iran-backed terror groups, the Wall Street Journal reported Wednesday, citing sources familiar with the matter.

What Is the DOJ Investigation Actually Targeting?

Is Binance itself under investigation or just its customers?

That's the question nobody can fully answer yet. Officials are seeking interviews and gathering evidence, but the WSJ was unable to confirm whether the investigation zeroes in on Binance as a company or on individual customers who used the platform to move money. That distinction matters enormously — the difference between a criminal referral for Binance executives and a regulatory action against users is a very different kind of legal problem.

Binance pushed back hard. A company spokesperson said the exchange had "categorically did not directly transact with any sanctioned entities" and that it had "uncovered a sophisticated, multijurisdictional pattern of financial activity" in which links to Iran were only identified after Binance began investigating alongside law enforcement. Translation: they're framing themselves as the good guys who caught the scheme, not the ones who enabled it.

Binance categorically did not directly transact with any sanctioned entities.

A Timeline of Trouble: Compliance Firings and Billion-Dollar Flows

This isn't the first crack in the wall. A Binance Iran sanctions report from Fortune — citing multiple sources and internal documents — alleged that Binance had fired members of its compliance team after evidence surfaced that Iran-linked entities received more than $1 billion through the exchange between March 2024 and August 2025. Firing the people who found the problem is, at minimum, a terrible look.

An earlier WSJ investigation had already put a number on the broader exposure: $1.7 billion in transactions tied to Iranian entities and Russian sanctions evasion running through the platform. Binance's response to that story was to sue.

Binance's Two-Front War: DOJ and the WSJ Lawsuit

Here's where it gets strange. Binance filed a lawsuit against the Wall Street Journal over its February 23 story, the one alleging the compliance staff firings. Dugan Bliss, Binance's Global Head of Litigation, claimed the reporting caused "significant reputational harm and business consequences" and called the suit a "necessary step to defend ourselves against misinformation." He accused the paper of "prioritizing clicks over journalistic integrity."

Suing the press to kill a story is a calculated risk — and one that keeps the story alive. Every legal filing is another news cycle. The Binance lawsuit Wall Street Journal action, rather than suppressing the narrative, has done the opposite: it's kept Binance in the headlines and handed reporters a fresh angle every week.

Meanwhile, Senator Richard Blumenthal (D-Conn) opened a formal inquiry into the exchange following the WSJ's initial reporting. Binance responded with a letter denying any Iranian sanctions violations. The Senator Blumenthal Binance probe is now part of a widening political spotlight that includes both congressional scrutiny and a federal investigation running in parallel.

Does Binance's Own Data Support Its Defense?

Binance isn't just denying — it's deploying numbers. The exchange claims it has built "one of the largest compliance programs" in crypto, pointing to the freezing of hundreds of millions tied to illicit activity. On sanctions specifically, Binance says its exposure dropped 96.8% from January 2024 to July 2025, with direct exposure to Iran's four major crypto exchanges falling 97.3% in the year through January 2026.

Those numbers, if accurate, show real progress. But they also confirm one thing the exchange would rather not emphasize: there was something to reduce in the first place. You don't cut exposure by 97% unless it was meaningful to begin with.

The DOJ hasn't announced formal charges. Whether this stays an inquiry or becomes something worse for Binance depends on what those interviewed witnesses have to say.
