Iran Reportedly Funneled Billions Through Binance To Fund Its Military

At a glance:

• Iran allegedly funneled over $2.5 billion through Binance, with $850 million in transactions by Babak Zanjani continuing until December 2025
• Binance flagged the alleged money laundering network but accounts remained active for up to 15 months, with $425 million potentially funding Iran's military
• Senator Richard Blumenthal has opened a probe into potential sanctions violations, while Binance faces scrutiny over its compliance despite a $4.3 billion penalty and former CEO's prison sentence

The Alleged Money Laundering Scheme

Iran has reportedly found ways to funnel billions of dollars through cryptocurrency exchanges like Binance, despite previous sanctions against the company and a jail sentence for its former CEO, Changpeng Zhao. An Iranian national named Babak Zanjani, who has described himself as an "antisanction operator," allegedly conducted $850 million in transactions on the Binance platform until as recently as December 2025, according to internal compliance reports reviewed by The Wall Street Journal. This activity represents just one part of a larger network that may have moved as much as $1.7 billion through the exchange, as previously reported by both The New York Times and WSJ.

The extent of the alleged scheme is particularly concerning given its potential military implications. Financial experts interviewed by the WSJ estimated that approximately half of the funds—about $425 million—could have been channeled through Binance to finance Iran's military operations. According to the compliance reports, Binance's own investigators assessed that the accounts in question constituted a sophisticated money laundering network designed specifically to finance the Iranian regime. This revelation comes at a time when international tensions surrounding Iran's nuclear program and regional activities remain high, making the financial implications of such transactions particularly significant.

Binance's Response and Previous Legal Troubles

In response to the allegations, Binance has maintained that the transactions in question were not connected to their platform. "It appears the overwhelming majority of these transactions have nothing to do with the Binance platform," a company spokesperson told the WSJ. The company emphasized that they do not allow transactions with any sanctioned individuals or wallets and that they took appropriate actions when they uncovered sanctioned accounts. However, Binance notably declined to answer specific questions about the transactions detailed in the reports, including why Zanjani's account remained active for as long as 15 months after being flagged by internal investigators.

The current allegations add to a growing list of legal and regulatory challenges facing Binance. In 2023, the company agreed to pay a $4.3 billion penalty and admitted to violating US sanctions, while its co-founder Changpeng Zhao was sentenced to prison on federal money laundering charges specifically related to Iran sanctions. Notably, Zhao was pardoned by former President Trump in 2023, adding a political dimension to the case. Earlier in 2023, Binance was also reported to be under investigation for potential violations of Russian sanctions, suggesting a pattern of compliance issues across multiple geopolitical contexts. The company has also taken legal action against the WSJ, suing the publication for defamation over previous reports on alleged Iran-linked money laundering activities.

Regulatory Response and Political Connections

The seriousness of the allegations has prompted significant regulatory attention. Democratic Senator Richard Blumenthal recently announced that he has opened a probe into potential Binance sanctions violations, citing evidence uncovered by the company's own internal investigators. "Binance appears to have ignored warnings and recommendations to prevent Iranian money laundering schemes on its cryptocurrency exchange," Blumenthal wrote in a statement highlighting the apparent failure of internal controls. This congressional investigation adds another layer of scrutiny to Binance's operations and could potentially lead to further regulatory action or legislation targeting cryptocurrency exchanges' compliance with international sanctions.

The situation becomes more complex when considering the broader political and blockchain ecosystem connections. Iran's cryptocurrency exchange Nobitex has been linked to the BNB Chain blockchain developed by Binance, as well as to Tron, another blockchain created by Justin Sun. Both Sun and Binance have emerged as backers of Donald Trump's crypto venture, World Liberty Financial, creating interesting intersections between the cryptocurrency industry, international politics, and sanctions enforcement. These connections raise questions about the extent to which cryptocurrency platforms may be inadvertently or deliberately facilitating financial activities that circumvent international sanctions regimes, particularly in politically sensitive regions.

What This Means for Crypto Regulation

The allegations against Binance underscore ongoing challenges in regulating the rapidly evolving cryptocurrency industry. Traditional financial institutions have decades of experience implementing anti-money laundering (AML) and know-your-customer (KYC) protocols, but cryptocurrency exchanges have struggled to establish equivalent safeguards that can effectively prevent illicit financial flows. The case of Binance and Iran highlights how sophisticated actors can potentially exploit gaps in compliance systems, particularly when dealing with decentralized technologies that can obscure transaction origins and destinations.

This incident may accelerate regulatory efforts to strengthen oversight of cryptocurrency exchanges, particularly those operating internationally. Regulators in the United States and Europe have already been increasing scrutiny of crypto platforms, with particular attention to their compliance with sanctions regimes. The Binance case could serve as a catalyst for more stringent requirements regarding transaction monitoring, customer due diligence, and reporting of suspicious activities. For the broader cryptocurrency industry, this situation emphasizes the importance of robust compliance frameworks not just as a legal requirement, but as a fundamental component of maintaining trust and legitimacy in the financial system. As digital assets continue to gain mainstream adoption, the ability to prevent illicit finance will become increasingly critical to the industry's long-term viability.
