1. SEC Targets Major U.S. Crypto Exchanges in Unprecedented Legal Actions

The SEC’s ongoing lawsuits against three of the largest digital asset exchanges in the United States—Coinbase, Binance, and Kraken—were arguably the most disruptive regulatory actions of 2024. This marked a significant and contentious shift in the SEC’s enforcement strategy, which had previously focused on issuers or promoters of digital assets.

The SEC alleged, among other things, that the exchanges acted as unregistered broker-dealers of investment contracts, purportedly represented by the digital assets sold on their platforms, raising serious questions about the agency’s regulatory reach and its approach to defining what constitutes a “security” in the digital asset space. Further compounding the disruptive nature and possibly intent of these actions, the SEC chose not to name the issuers of the assets alleged to be “crypto asset securities,” except in the case of Binance, where the exchange’s native token BNB was explicitly cited.

The complaint against Coinbase went even further, claiming that its self-custody wallet software facilitated unregistered broker-dealer transactions by integrating with decentralized finance (“DeFi”) platforms, which claim Coinbase successfully had dismissed. Additionally, the lawsuit asserted that Coinbase’s staking-as-a-service offerings constituted unregistered securities products, highlighting the SEC’s expansive view of its enforcement mandate.

Currently, the lawsuits against Kraken and Coinbase have proceeded to discovery, while the case against Binance awaits a ruling on the SEC’s Amended Complaint after portions of the original complaint were dismissed by the court.

These lawsuits are seen as “bet the company” cases, as a ruling in favor of the SEC could force the exchanges to delist all assets with unclear legal status—which could leave only a handful, such as ETH and BTC, as tradeable on those platforms.

The stakes are enormous, as these exchanges serve as the primary on-ramps between fiat currency and digital assets in the United States, particularly in light of the purported debanking of the industry described below. Any ruling, whether for or against these exchanges, will have profound and far-reaching implications for the digital asset economy, influencing the viability of current market participants and shaping the regulatory landscape for years to come.

However, with a new administration and changes in SEC leadership expected in 2025, there is a possibility these cases could see a shift
