The SEC filed 13 charges against Binance, BAM Trading, and CEO Changpeng Zhao on June 5, 2023, alleging the operation of an unregistered exchange, broker-dealer, and clearing agency. The enforcement action represented the most comprehensive attack on a major crypto exchange infrastructure in U.S. regulatory history.
The SEC alleged that Binance.US operated as a subsidiary entity independent from the global Binance platform, but claimed this independence was a "sham." Internal communications and user interface similarities demonstrated that Binance.US remained operationally integrated with international Binance systems, according to the agency's complaint. The allegation challenged Binance's core corporate structure argument.
The named securities included Bitcoin, Ether, and 11 altcoins: Binance Coin (BNB), Binance USD (BUSD), Solana (SOL), Cardano (ADA), Polygon (MATIC), Filecoin (FIL), Cosmos (ATOM), The Sandbox (SAND), Decentraland (MANA), Algorand (ALGO), and Axie Infinity (AXS). The SEC characterized each as an unregistered security based on the Howey test framework.
The SEC alleged commingling of customer funds across Binance entities, enabling transfers between accounts without transparent cost structures or regulatory approval. Customer assets held on the global Binance exchange faced operational risk from transfers to unregulated jurisdictions where Binance lacked regulatory licensing. The allegation created significant custody concerns about whether customer assets remained accessible.
Binance held approximately $65 billion in customer assets at the time of the filing, according to court documents. The scale of customer funds under Binance's control amplified regulatory concerns about operational risks and potential customer losses should regulatory restrictions force the exchange to liquidate positions or cease operations.
The enforcement action filed one day after a comparable suit against Coinbase, signaling a coordinated SEC enforcement strategy against major crypto exchanges. The parallel timing indicated that the agency had developed comprehensive enforcement positions against multiple platforms simultaneously, avoiding the possibility that regulatory announcements against one exchange would prompt competitors to alter practices or relocate operations.
The charges against Zhao individually created personal liability for the CEO. The SEC sought to hold Zhao responsible for corporate decisions to operate unregistered business lines and commingle customer funds. Personal liability exposure incentivized negotiated settlement to limit individual financial consequences.
Binance's operational continuity faced immediate threats from the enforcement action. Financial service providers including payment processors and banking relationships reviewed their exposure to Binance operations. Several banks suspended services to Binance-affiliated entities in the weeks following the filing, creating operational friction for customer withdrawals and deposits.
The lawsuit advanced the SEC's interpretation that most tokens traded on crypto exchanges qualified as securities. The broad token list encompassed major cryptocurrencies that the industry and many lawmakers had not anticipated would face securities regulation. The enforcement assertion contradicted expectations that Bitcoin and Ethereum would escape securities classification.
Binance's response emphasized the differences between centralized exchange tokens (BNB) that might qualify as securities and underlying blockchain assets that constitute commodities. The company characterized the SEC's positions as inconsistent with prior regulatory guidance and contrary to international precedent in jurisdictions including the UAE and Hong Kong where Binance maintained substantial operations.
The customer asset commingling allegation proved particularly damaging to Binance's defense. Evidence demonstrated that operational integration between Binance and Binance.US exceeded the formal corporate separation. Customers who had relied on representations that Binance.US operated as an independent entity faced concerns that regulatory restrictions might impair asset access.
The enforcement action triggered customer withdrawal surges, with Binance processing record withdrawal volumes in the weeks following the filing. Retail and institutional customers sought to reduce exposure to potential operational disruptions or seizure of funds by regulators. The withdrawal pressure created operational challenges for Binance's compliance teams.
Regulatory enforcement continued evolving through subsequent years, with negotiated settlements eventually replacing the comprehensive litigation strategy. By 2025, following changes in SEC leadership, Binance reached agreements with regulators that modified operational practices while permitting continued exchange operations under adjusted oversight arrangements.
