The long-running push for comprehensive U.S. crypto market structure legislation is heading toward a critical September deadline, but Republican advocates remain upbeat about its prospects.

Why Sep.15 Matters

Senate Banking Committee Chairman Tim Scott (R-SC) and Sen. Cynthia Lummis (R-Wyo.) on Tuesday said the legislation is essential to keep digital-asset innovation and investment in the United States.

At the SALT Conference in Wyoming, lawmakers noted that the CLARITY Act is scheduled for a Senate vote on Sep. 15 at 2 p.m. ET.

Lummis said lawmakers spent much of the past year negotiating with Democrats and combining provisions.

This expanded the bill from fewer than 300 pages to more than 600 pages as lawmakers attempted to resolve disagreements and incorporate requested changes.

Scott said he sees a “really good shot” at progress in September and argued that forcing a vote requires lawmakers to finally take positions rather than continue negotiating indefinitely.

He added that crypto-friendly action from the SEC and CFTC isn’t a substitute for legislation. Also, policy reversals can occur when administrations change.

“The only way to avoid that kind of seesaw is to embed it in legislation,” Scott said.

The “wrestling” continues on the ethics and rewards and now “they have a rearview mirror that’s getting bigger and the windshield’s getting smaller.”

Scott assures that they will “wrestle” that down one more time.

Why the White House’s Former Crypto Advisor Remains Bullish

Former White House crypto adviser Patrick Witt similarly said regulators have a substantial set of rulemakings ready if Congress fails to act.

The SEC and CFTC have so far given lawmakers room to pursue legislation, he said, but “we can’t wait forever.” If the September effort fails, regulators could move more aggressively on their own.

Despite the unresolved issues, Witt said negotiations have progressed from open-ended policy debates toward more binary choices, making a broader compromise increasingly possible.

He remains “optimistic and bullish” about the legislation’s prospects.

The urgency goes beyond crypto markets as Scott frames the bill as part of a broader competition over U.S. economic leadership.

Witt said other jurisdictions are closely watching Washington and could follow the U.S. regulatory framework once comprehensive crypto rules are in place.
