Federal Court Rejects Binance's Arbitration Gambit, Allowing Billion-Dollar Securities Lawsuit to Proceed

MIAMI, FL – April 14, 2026 – In a significant blow to the world's largest cryptocurrency exchange, a federal judge has denied a motion by Binance and its founder, Changpeng “CZ” Zhao, to force a sprawling class action lawsuit into private arbitration. The ruling clears a major legal hurdle for plaintiffs, allowing their case—which alleges widespread violations of U.S. securities laws and seeks over $1 billion in damages—to proceed in open federal court.

U.S. District Judge Roy K. Altman of the Southern District of Florida issued a detailed order dismantling the defendants' arguments, concluding that neither Binance nor Zhao could enforce an arbitration agreement they were not signatories to. The decision marks a critical victory for investors and adds to the mounting legal pressure on the embattled crypto giant, which has spent years navigating a gauntlet of regulatory actions and lawsuits in the United States and abroad.

The lawsuit will now move forward on its merits, setting the stage for a high-stakes legal battle over whether the exchange sold unregistered securities to American investors.

A Courtroom Setback on Corporate Structure

At the heart of Judge Altman's decision was a fundamental contract law principle: a party cannot typically be bound by or benefit from an agreement it did not sign. Binance and Zhao argued that the plaintiffs were bound by an arbitration clause found in the terms of service with certain U.S.-based Binance affiliates. However, the judge noted a crucial fact: those specific U.S. affiliates had already been voluntarily dismissed from the lawsuit by the plaintiffs.

In his order, Judge Altman held that the agreement only existed between the plaintiffs and the dismissed affiliates, not the global Binance entity or Zhao himself. As non-signatories, they had no legal standing to compel arbitration. The court flatly rejected the defendants' suggestion that the plaintiffs had engaged in improper legal maneuvering by dismissing the U.S. entities simply to avoid arbitration. The judge found no basis to disregard the complex corporate structure that the defendants themselves had created and operated under.

Binance's legal team also advanced a more technical argument, claiming that because the arbitration clause incorporated the rules of the American Arbitration Association (AAA), any questions about who should decide the issue—a judge or an arbitrator—were “delegated” to an arbitrator. This is a common legal strategy known as the “delegation doctrine.”

However, Judge Altman was unpersuaded. He explained that the incorporation of AAA rules does not “clearly and unmistakably” delegate such gateway issues when the central question is whether a non-signatory can enforce the agreement in the first place. The court reasoned that one must first establish that a valid agreement to arbitrate exists between the parties before the rules of that arbitration can take effect. With no such agreement in place between the plaintiffs and Binance or Zhao, the delegation argument failed.

The Billion-Dollar Allegations

The underlying class action, captioned Sizemore, et al. v. Changpeng Zhao, et al., is being litigated by The Moskowitz Law Firm and Boies Schiller Flexner LLP, two firms known for taking on complex financial cases. The lawsuit accuses Binance, Zhao, and several celebrity influencers of promoting and selling billions of dollars in unregistered securities to investors in Florida and across the country.

The complaint alleges that numerous crypto assets available on the platform, including Binance's own BNB token and BUSD stablecoin, as well as its crypto-lending products, were securities that were not registered with the appropriate authorities as required by state and federal law. This legal strategy mirrors other successful and ongoing class actions led by The Moskowitz Law Firm against other collapsed crypto platforms like FTX and Voyager Digital, which also focused on the sale of unregistered securities and deceptive marketing claims.

Following the court's decision, plaintiffs' counsel expressed confidence in their case. “We appreciate the Court's well-reasoned decision and look forward to moving forward on the merits,” said Adam Moskowitz, managing partner of The Moskowitz Law Firm, in a statement. By keeping the case in federal court, the plaintiffs retain the benefits of public proceedings, established discovery rules, and the potential for a jury trial, which are often seen as more favorable to consumer class actions than the private, confidential nature of arbitration.

Another Chapter in a Long Legal Saga

This ruling is not an isolated event but the latest development in a long and costly series of legal battles for Binance in the United States. The company's troubles culminated in November 2023 when it pleaded guilty to extensive violations of U.S. anti-money laundering (AML) and sanctions laws. The exchange agreed to pay a historic settlement exceeding $4.3 billion to the Department of Justice (DOJ), the Treasury Department's Financial Crimes Enforcement Network (FinCEN), and the Office of Foreign Assets Control (OFAC).

As part of that plea, Changpeng Zhao stepped down as CEO and personally pleaded guilty to failing to maintain an effective AML program. U.S. officials stated he deliberately turned a blind eye to transactions supporting terrorism, the illegal drug trade, and child sexual abuse. Zhao was sentenced to four months in federal prison in April 2024 and has since completed his sentence.

Beyond that landmark settlement, Binance remains embroiled in litigation with top U.S. regulators. In March 2023, the Commodity Futures Trading Commission (CFTC) sued the exchange and Zhao for operating an “illegal” digital asset derivatives exchange and for “willful evasion” of U.S. law. Just a few months later, in June 2023, the Securities and Exchange Commission (SEC) filed its own sweeping lawsuit, lodging 13 charges against Binance and Zhao that included operating unregistered exchanges, misrepresenting trading controls, and selling unregistered securities.

This pattern of intense regulatory scrutiny extends globally. In March 2026, for example, an Australian federal court fined Binance's local unit nearly $7 million for improperly classifying retail investors, exposing them to risky financial products without adequate protections. This latest ruling in Florida adds yet another front to Binance's multi-faceted war with regulators and litigants.

Broader Implications for Crypto and Corporate Law

The significance of Judge Altman's decision extends far beyond the parties involved, carrying potential ramifications for the entire cryptocurrency industry and corporate legal strategy at large. By refusing to allow Binance to shield itself behind an arbitration clause signed by a separate affiliate, the court has sent a clear signal that complex corporate structures may not be a reliable defense against U.S. litigation.

For years, consumer advocates have argued that mandatory arbitration clauses are used by large corporations to suppress legal claims by forcing individuals into private, often secretive, proceedings where the playing field is tilted in the company's favor. This ruling empowers investors by affirming their right to band together in a class action and have their day in a public court.

Legal analysts suggest the decision could prompt other digital asset platforms to re-evaluate their terms of service and corporate structures. Companies that rely on a web of international and domestic entities may find themselves similarly vulnerable if courts continue to scrutinize which entity is truly responsible for services provided to U.S. customers. The ruling reinforces the idea that the long arm of U.S. law will reach the entities ultimately in control, regardless of contractual fine print.

With the path to arbitration now blocked, the billion-dollar class action against Binance will proceed toward discovery and potentially a trial. The outcome of the case could further define how U.S. securities laws apply to cryptocurrency exchanges and may set a powerful precedent for investor lawsuits across the burgeoning digital asset industry.
