Justice Department investigates whether Binance let Iran-linked trading run on its platform

The compliance officer filling in a counterparty review this week has three documents to work from: a spokesperson's statement, a company blog post, and a court docket. Binance spokesperson Ross O'Leary told Gizmodo: "We maintain a zero-tolerance policy for sanctions violations. We fully cooperate with law enforcement, and we remain committed to rooting out and shutting down bad actors." ^[11]

The reported conduct is harder to enter in a control register. The Wall Street Journal and the New York Times reported in February 2026 that Binance fired or suspended at least four internal compliance investigators who had raised concerns about $1.7 billion in payments from two Hong Kong companies, Blessed Trust and Hexa Whale, to crypto wallets allegedly tied to sanctioned Iranian-backed entities including Yemen's Houthi rebels ^[5]. Binance said in a March 2026 blog post that the "departures had nothing to do with the investigation itself" and that claims it had denied investigators access were "demonstrably false and contradicted by internal records" ^[9]. It sued the Journal for defamation, and the Journal filed a motion to dismiss last month ^[10].

Set $1.7 billion against the platform's own numbers. Binance recorded $11.4 trillion in trading volume in the first half of 2026 ^[3] and reported more than 320 million users in July ^[4]. Divide 1.7 billion by 11.4 trillion and you get 0.00015: the flagged payments are about 0.015 percent of half-year volume ^[16].

Two other items belong in the same file. The Guardian noted that President Donald Trump pardoned now-former Binance chief executive Changpeng Zhao in October 2025 for his conviction in the 2023 case ^[7]. Binance has reportedly since lobbied regulators to remove the independent federal compliance monitors it agreed to in that settlement ^[8].

Bloomberg noted that an investigation is not a charge, and that federal investigations sometimes end without one, a practice known as declination ^[13]. The reporting so far concerns Binance, the two Hong Kong companies and the Iranian-backed entities; it does not identify any third-party firm whose flow passed through the flagged wallets ^[18].

So the useful review is narrow. It sorts each venue a firm routes through on two things: whether the control the firm depends on is one it can read, such as a monitor's report or a log delivered to it, or one asserted in a statement; and whether the flow could move in a week or only in a quarter. Asserted plus slow to move is the cell where the exposure sits, and the exposure in that cell is the one that needs a named owner and a written escalation path.

On paper, exchanges fall under much of the same regulatory structure as traditional financial institutions, and in practice criminals use crypto for its decentralization and pseudonymity ^[17]. Chainalysis estimated in March 2026 that the value of crypto sent to sanctioned entities rose nearly 700 percent in 2025, reaching $104 billion ^[14].
