The Digital Asset Market Clarity Act (H.R. 3633) opened for full Senate floor debate on May 19, 2026, less than a week after the Senate Banking Committee advanced it 15-9 on May 14. For the first time, the full Senate is debating a statute that would write permanent regulatory boundaries for digital assets into federal law.

Sen. Elizabeth Warren (D-Mass.) delivered a floor speech on May 19 calling the bill one "written by the crypto industry, for the crypto industry" — echoing and sharpening language she used at the May 14 committee markup, where she told colleagues: "Our job is not to advance a pro-industry crypto bill that will put American consumers, investors, our national security and our financial system at risk."

What the bill does

The CLARITY Act sorts digital assets into three regulatory buckets. Digital commodities — assets whose value derives from use of the underlying blockchain rather than from the efforts of a centralized team — fall under Commodity Futures Trading Commission (CFTC) jurisdiction. Securities remain with the SEC. Stablecoins get shared SEC/CFTC oversight.

Bitcoin and Ethereum fit the "digital commodity" definition under the bill's "mature blockchain system" standard, as would most established Layer 1 protocols with sufficiently decentralized networks. The classification matters because CFTC oversight carries a lighter registration and compliance burden than securities law, and because it would end years of SEC enforcement actions premised on commodity tokens being securities.

For exchanges, the bill grants the CFTC exclusive oversight of spot and cash markets for digital commodities — a significant expansion from the CFTC's current anti-fraud authority. Platforms would register with the CFTC and operate under a 180-day provisional registration window while the agency finalizes rules. DeFi validators and node operators are explicitly excluded, provided they do not control customer funds.

The bill also prohibits the Federal Reserve from issuing a retail central bank digital currency, a provision that secured Republican support but drew no Democratic backing.

The floor fight

Warren was the loudest voice at the committee markup and carried that opposition to the floor. Her May 14 committee opening statement tied the bill directly to Trump administration conflicts of interest: "Our job is not to advance a pro-industry crypto bill that will grease the skids for the President of the United States, crypto grift while tens of millions of Americans can't afford the basics."

Before the committee vote, Warren had filed 44 amendments, including one that would have blocked the Federal Reserve from granting master accounts to crypto companies and another that would have empowered the government to sanction crypto platforms. None passed at committee. More than 130 total amendments were filed across both parties ahead of the May 14 markup, according to Fortune's review.

On the floor on May 19, Warren repackaged the central objection in sharper language. The specific amendments she has offered for floor consideration and their vote outcomes had not been certified in public records available as of the time of publication. Floor amendment results in the Senate are recorded in the Congressional Record after votes are completed; those records were not yet available for the May 19-20 debate period.

The path to law

The bill's trajectory runs: House passage (294-134, July 17, 2025) → Senate Banking Committee (15-9, May 14, 2026) → Senate floor (underway). If it passes the full Senate, the Senate version must be reconciled with the House-passed text — the two versions diverge on committee jurisdiction, stablecoin treatment, and ethics provisions relating to the president's crypto holdings. Reconciliation could happen through a conference committee or amendment substitution before a final vote.

Senate Banking Committee Chairman Tim Scott (R-S.C.) has called it the highest-priority financial legislation of the session. Galaxy Digital's head of firmwide research, Alex Thorn, estimated a 75% probability of passage in an appearance on Bloomberg Crypto on May 19.

The remaining obstacles are not primarily procedural. Banking industry representatives have objected to provisions that would allow crypto firms to obtain OCC charters, creating a parallel path to the banking system outside traditional bank supervision. Brooke Ybarra, SVP of Innovation and Strategy at the American Bankers Association, said on Bloomberg Crypto on May 19 that banks find the bill "too vague" on the boundary between crypto and traditional banking activities.

Democratic votes are harder to count. Most Democratic senators have followed Warren's lead in demanding ethics amendments that would bar the president and senior executive branch officials from profiting on digital assets while in office. Those amendments failed at committee. Whether Senate Majority Leader John Thune has 60 votes to close debate depends on whether any Democrats can be peeled away from that position.

More than 100 firms — including Coinbase, Ripple, and a16z — co-signed a letter urging the Senate Banking Committee to advance the bill in April. Ripple alone contributed $48 million to FairShake, the crypto industry's primary political action committee, during the 2025-2026 cycle, according to FEC filings analyzed by FinTech Weekly. Warren's floor speech put that spending record directly in front of colleagues debating the bill.

MiCA comparison

The EU's Markets in Crypto-Assets Regulation, which came into full effect in December 2024, covers crypto-asset service providers (CASPs), stablecoin issuers, and token issuers operating in EU member states. The CLARITY Act covers similar ground on market structure but does not include MiCA's consumer disclosure requirements for individual token offerings, nor MiCA's passporting regime that lets a firm licensed in one EU jurisdiction operate across all 27 member states. MiCA also does not have an equivalent to the CLARITY Act's explicit DeFi safe harbor for validators and node operators.

Where MiCA is prescriptive and completed, the CLARITY Act delegates substantial rule-writing to the CFTC and SEC after passage. For global firms operating in both jurisdictions, the CLARITY Act's passage would close the compliance gap but create a period of regulatory uncertainty during the CFTC's rulemaking process that MiCA does not impose on European operations.

Floor amendment vote results from the May 19-20 Senate floor debate were not available in certified public records at the time of publication. This piece will be updated when the Congressional Record is published.
