The Senate Banking Committee opened markup on H.R. 3633, the Digital Asset Market Clarity Act of 2025, on May 14, 2026, with Republicans and Democrats locked in a partisan standoff over the most sweeping federal cryptocurrency regulation attempt in U.S. history. Committee Chairman Tim Scott (R-SC) and Ranking Member Elizabeth Warren (D-MA) clashed repeatedly over amendment procedure, bill capture, and national security, forcing a vote deadline before the Memorial Day recess to keep the legislative calendar intact.

How a Regulatory Vacuum Fractured Committee Unity

For years, the digital asset sector operated in a regulatory gray zone, a gap that Cynthia Lummis (R-WY), the bill’s primary architect, argued creates immediate illicit finance and consumer fraud risks. The bill adds 33,000 words and 219 pages of regulatory language across three pillars: consumer protection, innovation retention, and national security. Lummis framed the legislation as a hard-won compromise that establishes anti-money-laundering provisions, risk-based examination standards, and Treasury reporting requirements. Warren countered that the absence of framework is preferable to what she characterized as industry-written law that erodes securities protections and preempts state consumer fraud enforcement. The 13,460 crypto kiosk fraud complaints filed in 2025, resulting in $389 million in losses, underscored the stakes of both positions.

Amendment Deadlock and Procedural Warfare

The committee received 130+ amendments, but dispute erupted immediately over which would receive floor votes. Scott attributed amendment exclusions to objections from Warren’s staff, while Warren accused the chairman of unilateral gatekeeping. Two amendments passed: Mike Rounds (R-SD) secured a 15-9 vote on his amendment, and Dave McCormick (R-PA) won 18-6 on his. Warren’s amendments failed 11-13. Jack Reed (D-RI) defended amendment procedure as foundational to markup integrity. The procedural friction signals deeper disagreement: Warren opposes the bill’s framework on securities law erosion, bank crypto risk exposure, and national security grounds, citing Trump family crypto gains of at least $1.4 billion since the administration took office. Republicans, including Lummis, argue the current regulatory void enables greater national security vulnerabilities.

Bipartisan Path Remains Uncertain

The committee’s 13 Republicans and 11 Democrats reflect the 60-vote threshold needed for Senate passage, making crossover votes critical. Democrats Mark Warner, Andy Kim, and John Kennedy were named as potential swing votes, though their positions remain undisclosed. A CoinDesk survey ranked crypto as a 1% voter priority, suggesting limited electoral pressure on either side. The vote must occur before Memorial Day recess or the legislative calendar resets, compressing negotiation time. Warren’s framing of the bill as industry-captured and her national security objections may appeal to some centrist Democrats, but Lummis’s argument that regulatory clarity reduces illicit finance risk may persuade others.

What Happens Next

The committee faces a hard deadline to vote before recess. If the markup concludes without a floor agreement on amendment procedure, the bill advances to the Senate floor with procedural uncertainty intact. External stakeholders including AARP and the National Sheriffs Association have weighed in, signaling broader coalition stakes. The outcome will determine whether federal crypto regulation proceeds through consensus or partisan division.
