US Securities Exchange Act Digital Asset Trading Regime

The Exchange Act was enacted to regulate securities exchanges and over-the-counter securities markets. For digital asset trading, the key threshold questions are whether the asset is a security and whether the platform’s activity fits an Exchange Act category such as exchange, broker, dealer, clearing agency, or transfer agent.

SEC staff applies a functional approach. A platform that offers trading in digital asset securities and operates as an “exchange” must register as a national securities exchange or qualify for an exemption, such as Regulation ATS. The analysis turns on what the system does, including whether it brings together orders of multiple buyers and sellers using established, non-discretionary methods. Labels such as “decentralized” or “exchange” do not control.

• National securities exchange: A registered exchange is subject to SEC oversight and must maintain rules addressing fraud, manipulation, member discipline, and compliance with federal securities laws.
• Alternative trading system: An ATS route can be available, but the ATS must register as a broker-dealer, generally become a FINRA member, file Form ATS, and comply with securities laws and SRO rules.
• Broker-dealer activity: A platform or intermediary that facilitates issuance or secondary trading in digital asset securities may separately trigger broker or dealer registration analysis.
• Adjacent services: Wallet, custody, clearing, transfer, and settlement functions may raise additional registration or safeguarding questions depending on the facts.

The SEC’s 2017 DAO Report was an early public application of federal securities laws to blockchain-based tokens. The SEC stated that The DAO tokens were securities and that securities exchanges providing trading in such securities must register unless exempt. In 2018, SEC staff expanded the platform analysis by discussing online trading platforms, decentralized trading technology, ATS registration, broker-dealer registration, and other platform functions.

These statements do not create a bespoke digital asset trading license. Instead, they explain how existing Exchange Act categories may apply when a crypto asset is a security or when a platform provides securities-market functions. The 2018 multi-division statement also says it represents staff division views and is not a Commission rule, regulation, or Commission statement.

Congress has considered broader digital asset market-structure legislation that would change parts of this landscape. H.R. 3633, the Digital Asset Market Clarity Act of 2025, was received in the Senate and referred to the Senate Banking Committee on September 18, 2025. The bill text includes proposed Exchange Act amendments on digital commodity-related definitions, permitted payment stablecoins, ATS eligibility, dual-registered SEC/CFTC entities, DeFi exclusions, and recordkeeping modernization.

As of June 4, 2026, those proposed changes should be described as pending legislation, not current law. Senate Banking announced on May 14, 2026 that the CLARITY Act advanced out of committee by a 15-9 vote and moved to the Senate floor, while CRS described the broader market-structure bill as still under congressional consideration.

For taxonomy purposes, this profile should be treated as an in-force U.S. securities and market-structure regime, with pending CLARITY Act proposals noted as related legislative developments rather than enacted amendments.
