The Clarity Act, opposed by Warren, fails in Senate procedural vote 49-50.

The U.S. Senate blocked the Clarity Act, a bill to establish rules for the cryptocurrency market, in a procedural vote on September 15 that failed 49-50, preventing it from advancing to the next stage of Senate consideration. Senator Elizabeth Warren said in a floor speech that crypto regulation is necessary but opposed the bill over insufficient consumer protection, national security, and conflict-of-interest provisions for public officials. The procedural vote only determined whether the Senate would continue deliberating the bill, not a final up-or-down vote on its provisions. The bill had already passed the House and the Senate Banking Committee before stalling in the full Senate. The outcome leaves U.S. crypto market structure legislation in limbo, and attention now turns to whether lawmakers can revise the bill to address Warren's concerns and bring it back for another procedural attempt.
