White House crypto adviser Patrick Witt warned that failure of the US Senate's Sept. 15 procedural vote could leave the CLARITY Act without a clear route back to the floor for years. Witt, executive director of the US President's Council of Advisers on Digital Assets, said Republican support for the motion to proceed was at or near all 53 GOP senators and urged Democrats to open debate even if they oppose the bill. The legislation would establish whether tokens are securities or commodities, creating the first comprehensive US federal framework for the crypto industry. The House passed it 294-134 in July 2025, and it now needs 60 Senate votes. If the bill fails, Witt said the Securities and Exchange Commission (US securities regulator) and Commodity Futures Trading Commission (US derivatives regulator) would pursue an aggressive rulemaking agenda, including a planned SEC innovation exemption. Polymarket traders put the odds of enactment in 2026 at 18%, up from about 15% a week earlier.
