What is the CLARITY Act? The complete guide to US crypto market structure regulation

For a decade, the central question in US crypto regulation was not whether digital assets were legal. It was which regulator had authority over them, and under which rulebook. The CLARITY Act is the legislation designed to resolve that ambiguity. The Senate failed to advance it in September 2026. But its framework is already reshaping how institutional capital thinks about digital asset classification, custody, and compliance.

The most significant piece of US crypto market structure legislation ever to pass one chamber of Congress has stalled in the Senate. The Digital Asset Market Clarity Act (CLARITY Act, H.R. 3633) passed the House of Representatives on July 17, 2025 with a 294-134 bipartisan majority and cleared the Senate Banking Committee on May 14, 2026 by 15-9. On September 15, 2026, a Senate cloture vote fell short of the 60 votes required to advance the bill to a floor vote, with the motion failing 49-50. For asset managers, family offices, token issuers, and anyone building around digital assets in the US market, understanding what the CLARITY Act does, where it now stands, and what its stalling means for their operations is no longer optional preparation but due diligence.

What is the CLARITY Act?

The Digital Asset Market Clarity Act of 2025, universally known as the CLARITY Act, is a comprehensive federal bill that establishes a regulatory framework for the classification, trading, and supervision of digital assets in the United States. Its central purpose is to resolve a problem that has defined the US crypto industry for over a decade: neither the Securities and Exchange Commission (SEC) nor the Commodity Futures Trading Commission (CFTC) had a clear, statutory mandate over digital assets, and both claimed overlapping authority, creating what practitioners came to call "regulation by enforcement."

The CLARITY Act would end that ambiguity by dividing regulatory jurisdiction along a clear axis. The House-passed text grants the CFTC exclusive authority over "digital commodities" and creates a category called "investment contract assets" for tokens remaining tied to a centralised issuing entity. The Senate text uses different terminology, introducing "ancillary assets" as the related category. Both versions preserve SEC authority over tokens tied to ongoing managerial effort, and both provide Bitcoin and Ethereum with an unambiguous statutory commodity classification. The two texts have not been reconciled. The implications for institutional capital, once reconciled and enacted, would be material.

From enforcement to framework: the legislative history

The absence of a US digital asset regulatory framework was not an oversight. It was the product of sustained political disagreement, competing agency turf claims, and a decade of failed legislative attempts. The SEC, under successive chairs, treated most token offerings as unregistered securities and brought enforcement actions accordingly, the most prominent being against Ripple, Coinbase, and Binance. The CFTC, for its part, treated Bitcoin as a commodity within its jurisdiction and repeatedly called on Congress to extend its authority to spot digital commodity markets. Courts produced rulings that resolved individual cases but left the structural question open.

The legislative push that eventually produced the CLARITY Act began in earnest in 2023, when the House Financial Services Committee and the House Agriculture Committee jointly developed a draft market structure bill. Multiple rounds of hearings, redrafts, and bipartisan negotiations followed through 2024. On May 29, 2025, House Financial Services Committee Chairman French Hill formally introduced H.R. 3633, the Digital Asset Market Clarity Act, with eight original co-sponsors spanning both parties. Both the House Financial Services Committee (32-19) and the House Agriculture Committee (47-6) advanced the bill in June 2025, with the Agriculture Committee's near-unanimous margin signalling unusual cross-party consensus on the CFTC jurisdiction question.

The House passed the CLARITY Act on July 17, 2025, by 294-134, during what Congress designated "Crypto Week," a coordinated legislative push that also advanced the GENIUS Act and the CBDC Anti-Surveillance Act. Senate progress has been slower. The Senate Banking Committee released a 278-page discussion draft in January 2026 and the Senate Agriculture Committee published a companion digital commodity draft the same month. After months of negotiation over contested provisions including stablecoin yield, DeFi definitions, and the precise boundary of the SEC-CFTC jurisdiction split, the Senate Banking Committee passed a 309-page compromise text by 15-9 on May 14, 2026. The bill was formally placed on the Senate Legislative Calendar on June 1, 2026. Senate Republicans released a merged 616-page substitute text combining both committees' versions on July 22, 2026, adding an ethics title developed with the White House. A final updated text was released on September 14, 2026, the day before the cloture vote.

What the CLARITY Act would do

The CLARITY Act, in its 616-page merged form, covers classification, jurisdiction, registration, custody, and investor protection across the full digital asset market. Its most consequential provisions fall into four areas.

1. The three-category classification system

The Act would sort every digital asset into one of three categories, each with a designated regulator and compliance framework. Digital commodities are assets whose value is intrinsically linked to the use of a decentralised blockchain protocol. Bitcoin and Ethereum are the primary statutory examples. The CFTC would receive exclusive jurisdiction over spot digital commodity markets, bringing them under the Commodity Exchange Act for the first time. The House text calls the second category "investment contract assets" — tokens remaining tied to a centralised issuer, a development team, or ongoing entrepreneurial effort — while the Senate text uses the term "ancillary assets" for a related concept. Both versions keep these tokens under SEC jurisdiction, subject to securities law. Permitted payment stablecoins are fully reserved tokens used primarily for payments and settlement, to be governed separately under the GENIUS Act, which takes effect on January 18, 2027, or 120 days after final implementing regulations are issued, whichever is earlier. The critical design feature of this system is that it would not be static. A token would begin its life in the SEC-regulated category and could graduate to digital commodity status under CFTC jurisdiction once its underlying blockchain achieves sufficient decentralisation, a transition defined through a "maturity test."

2. The decentralisation test and maturity pathway

The maturity test is the Act's most consequential mechanism for token issuers and investors. It would define the conditions under which a digital asset transitions from SEC-regulated to CFTC-regulated commodity, ending the issuer's ongoing disclosure obligations and removing the security classification that has constrained institutional participation. The key criteria would include: no single entity controlling more than 20% of the token supply; the blockchain having been in active operation for at least one year; the issuer no longer exerting unilateral control over protocol upgrades; and the token's value being primarily driven by network use rather than issuer activity. Assets that had a spot ETF approved before January 1, 2026 would qualify automatically. Spot Solana ETFs launched in late 2025 and Solana was named as a digital commodity in the March 2026 SEC-CFTC joint interpretive release, placing it on the automatic pathway.

3. Exchange and intermediary registration

The Act would establish a federal registration framework for Digital Commodity Exchanges (DCEs) and Digital Asset Broker-Dealers. Exchanges handling both digital commodities and investment contract assets would require dual registration with both the CFTC and SEC. The Act would also introduce mandatory customer asset segregation rules, requiring exchanges to hold client digital assets in separately identified accounts, distinct from firm assets, a reform directly targeting the commingling failures that caused the FTX collapse.

4. Safe harbours for developers and DeFi

Section 604 of the bill, which incorporates the Blockchain Regulatory Certainty Act, provides explicit legal protections for non-custodial software developers, shielding them from money-transmitter registration requirements and Bank Secrecy Act obligations. Developers who write and publish open-source protocol code would not be treated as issuers or intermediaries, removing the threat of enforcement against protocol contributors. DeFi protocols that operate without a centralised operator, have no ability to freeze or reverse transactions, and do not custody user assets would be exempt from exchange registration requirements. Law enforcement groups have actively lobbied against this provision, arguing it could create loopholes; the scope of the exemption remains a live negotiating point.

Where the bill stands and what remains contested

The CLARITY Act is not law, and the September 15, 2026 cloture failure has narrowed its near-term prospects substantially. The vote fell 49-50, eleven votes short of the 60 required to advance the bill to a floor debate. Republican senators Collins, Hawley, Moran, and Tillis voted no. No Democrat voted yes, despite sponsors making more than 100 changes at Democratic request. The immediate sticking point was not only the SEC-CFTC jurisdiction split that has dominated public discussion, but ethics language governing officials' crypto holdings and objections from community banks over stablecoin rewards provisions. Several Democratic senators called the result a setback but not the end. Senator Thom Tillis voted no specifically to preserve the procedural right to file a motion to reconsider, though the bill's lead sponsor has indicated the failed vote effectively ends its 2026 prospects.

The provisions with the most durable cross-chamber consensus are: CFTC exclusive jurisdiction over spot digital commodity markets; the commodity classification of Bitcoin and Ethereum; mandatory customer asset segregation; and the broad principle of a maturity pathway from SEC to CFTC jurisdiction. The key terminology, test criteria, and scope of the developer safe harbour remain actively contested between the House and Senate texts and have not been reconciled.

The contested provisions centre on four issues. First, the treatment of tokenised equities and real-world assets, where the House and Senate versions differ on whether tokenised securities fall under SEC or CFTC jurisdiction. Second, the precise definition of DeFi exemptions, where banking industry groups have lobbied to narrow the exemption. Third, the relationship between CLARITY Act provisions and the GENIUS Act's stablecoin yield rules. Fourth, ethics provisions covering officials' digital asset holdings, which proved the proximate cause of the September vote failure. Coinbase CEO Brian Armstrong had publicly withdrawn support for the Senate draft twice, first on January 14, 2026 over stablecoin rewards, tokenised equities, and DeFi restrictions, and again in March 2026. A Tillis-Alsobrooks compromise on stablecoin rewards reached in May 2026 brought Coinbase back, but the ethics dispute and remaining contested provisions ultimately sank the September vote.

What this means for institutional investors and asset managers

Even before the CLARITY Act becomes law, its framework is already shaping institutional behaviour. The March 2026 joint SEC-CFTC interpretive release identified 18 crypto assets as digital commodities — 16 whose tokens underlay CFTC-regulated futures contracts at the time, including Bitcoin, Ether, Solana, and XRP, plus Algorand and LBRY Credits named separately in a footnote, and confirmed that protocol staking across all four models — solo, self-custodial with third parties, custodial, and liquid — falls outside securities law. The emerging regulatory framework has coincided with a significant expansion in institutional crypto product development, with firms including VanEck, BlackRock, and Fidelity advancing product pipelines across digital asset categories during 2025 and 2026.

For family offices and institutional allocators, the clearest near-term implication is counterparty and custody risk reduction. The mandatory customer asset segregation rules, once in force, would impose on digital asset exchanges the same client money protections that traditional broker-dealers have operated under for decades. The FTX collapse in 2022 was substantially a custodial commingling failure. The CLARITY Act would address that failure structurally, not through guidance but through federal statute. Institutions that have held back from direct digital asset exposure over custody concerns would face stronger statutory custody safeguards under the post-CLARITY framework.

For token issuers and venture investors, the maturity pathway from the SEC-regulated category to digital commodity is the most commercially significant provision. A token that achieves commodity status under the decentralisation test would exit ongoing SEC disclosure obligations, become eligible for listing on CFTC-regulated commodity exchanges, and qualify for a broader range of institutional investment mandates currently restricted to securities. The practical effect would be a re-rating of assets discounted purely by regulatory uncertainty.

The institutional due diligence framework

For institutions assessing exposure ahead of CLARITY Act implementation, the key questions to track are:

What comes next: the path forward after the September vote

The September 15 cloture failure has effectively closed the 2026 legislative window. The House left Washington until after the November 3 election, meaning that even Senate passage could not produce an enacted law before year-end in the ordinary course. The realistic routes are the lame-duck session between the election and year-end, or the 120th Congress beginning in January 2027. Senator Lummis, who championed the bill, had warned before the vote that failure before the midterms could push the next viable window to 2030, given the unpredictable composition of the incoming Congress. If Democrats win the Senate majority in November, the Senate Banking Committee would likely be chaired by Senator Elizabeth Warren, a persistent opponent of the legislation.

With legislation stalled, regulatory agencies are filling the gap through exemptions and rulemaking. The March 2026 SEC-CFTC interpretive release provides workable agency-level classification for 18 named assets. The SEC's Regulation Crypto Assets comment period closes October 20, 2026. The GENIUS Act was enacted on July 18, 2025 but does not take effect until January 18, 2027. These agency-level actions are faster to implement than statute but reversible by future administrations, offering a less durable foundation than the statutory framework the CLARITY Act would provide. For international firms, the EU's MiCA framework now offers a clearer rulebook than anything currently available in the US.

Prediction markets reflect the diminished near-term outlook. Polymarket, which has seen over $23.8 million in trading volume on the contract tracking H.R. 3633's 2026 passage, prices the bill's chances of being signed into law this year at approximately 5%. That is down from a February 2026 peak of 82%, and from nearly 30% on the morning of the vote itself, before the cloture motion failed.

For institutions, the planning framework is unchanged in its logic, even if the timeline has extended. Build around the provisions with genuine cross-chamber consensus now. Track the contested provisions — particularly the terminology reconciliation and Section 604 scope — before committing product or custody decisions to their current form. Treat the March 2026 agency guidance as the operative classification framework today, and the GENIUS Act as the stablecoin rulebook from January 2027 onward. The question is not whether a statutory framework will come; it is when, and under which Congress.

The bottom line

The CLARITY Act will not end the work of building a regulated digital asset industry. When it passes, it will make that work possible at institutional scale. A decade of regulatory ambiguity has not prevented the growth of the crypto market; it has prevented the growth of the infrastructure around it, the exchanges, custodians, prime brokers, and product structures that move institutional capital efficiently and safely. That infrastructure buildout has been stalled not by risk appetite but by legal uncertainty.

The commodity classification of Bitcoin and Ethereum, the customer asset segregation mandate, the maturity pathway for tokens, the DeFi developer safe harbours: these are the foundational rules that would allow banks, asset managers, endowments, and family offices to participate in digital asset markets without navigating enforcement risk on every transaction. JPMorgan analysts have described passage as broadly positive for crypto and tokenisation, while also warning that elements of the Senate draft — including DeFi treatment and AML asymmetries — could deter institutional participation. What they are pointing to is not a new market being created. It is an existing one finally becoming fully accessible.

September 2026 was not the end of that story. The agency layer has provided a working rulebook for named assets. The statutory guarantee has not followed. The framework is known, the consensus on its core is real, and the gap it was designed to close has not closed. The preparation continues.
