Catenaa, Monday, May 18, 2026- More than 100 amendments were filed ahead of a crucial US Senate markup of the CLARITY Act, exposing deep political divisions over stablecoins, decentralized finance, ethics rules and crypto regulation as lawmakers raced toward a proposed July deadline for passing landmark digital asset legislation.
The amendments were submitted before the Senate Banking Committee’s scheduled markup session on May 14, turning the crypto market structure bill into one of the most heavily contested financial proposals currently before Congress.
The CLARITY Act would establish the first broad federal framework governing the US crypto industry by splitting oversight between the Securities and Exchange Commission and the Commodity Futures Trading Commission.
The House previously passed its version of the bill with bipartisan support in July 2025.
The White House reportedly wants the legislation signed before July 4, 2026, leaving lawmakers only weeks to resolve disputes that already delayed earlier markup attempts.
The large number of amendments revealed growing tension between crypto firms, banks, regulators and lawmakers over how the industry should be regulated.
Several Democratic senators pushed ethics amendments targeting public officials and their families involved in crypto ventures.
Sen. Elizabeth Warren and other Democrats backed measures designed to prevent elected officials from profiting from stablecoins or digital asset projects while in office.
The ethics debate intensified amid scrutiny surrounding President Donald Trump’s family-linked crypto activities.
Some Republicans viewed the proposed ethics language as an attempt to derail the legislation before a final Senate vote.
Stablecoin Battle
Another major fight centered on stablecoin yield products.
Banking groups pushed lawmakers to tighten language that could allow stablecoin issuers to offer interest-bearing products competing with traditional bank deposits.
Lobbying efforts intensified after banking associations reportedly sent thousands of letters to Senate offices urging changes to the bill.
The debate focused heavily on whether the legislation should ban stablecoin interest payments entirely or leave room for certain yield-bearing products.
Industry analysts said the wording could shape billions of dollars in future crypto financial products.
The bill’s broader structure still places most decentralized digital commodities under CFTC oversight while leaving investment contracts and fundraising activities under SEC authority.
DeFi Concerns
Another flashpoint involved protections for decentralized finance developers.
The Blockchain Regulatory Certainty Act provisions inside the Senate proposal seek to clarify that noncustodial software developers are not automatically treated as money transmitters.
Crypto industry groups strongly backed those protections, arguing developers should not face criminal liability simply for publishing software code.
Banks and some lawmakers warned the protections could weaken anti-money laundering enforcement and create regulatory loopholes for decentralized platforms.
Moderate Democrats may ultimately decide whether the DeFi protections survive the final Senate negotiations.
Analysts said many amendments were likely negotiating tactics rather than serious attempts to rewrite the entire bill.
Still, several provisions could determine whether enough bipartisan support exists to overcome the Senate’s 60-vote threshold.
Market Stakes
Prediction markets and political betting platforms reflected growing uncertainty over the legislation’s future.
Polymarket traders recently estimated roughly 60% odds that the CLARITY Act eventually becomes law during 2026.
Analysts said the Senate vote may become one of the most important moments yet for the American crypto industry.
The legislation would shape federal oversight of trading platforms, token issuers, stablecoins and decentralized finance operations for years to come.
Industry groups warned failure to pass the bill could leave regulatory uncertainty hanging over the rapidly expanding digital asset market.
