CLARITY Act’s biggest Senate vote could happen before the bill is actually finished

White House digital assets adviser Patrick Witt has reduced the Senate's immediate choice on the CLARITY Act to “get on the bill and let's keep talking.”

The Sept. 15 vote is a cloture vote on the motion to proceed to H.R. 3633, scheduled to ripen at 2:15 p.m., according to the Senate floor schedule. Sixty votes would open debate and an amendment process.

Four days before that procedural test, Republicans released EHF26718, proposed substitute text for CLARITY that adds a Commodity Futures Trading Commission framework for protocols that call themselves decentralized while remaining under an identifiable party's control.

The change repairs part of the bill's regulatory architecture and gives negotiators a targeted response to concerns about DeFi and prediction markets.

No senator who raised prediction market and Tribal-sovereignty concerns has publicly said the substitute changed their vote. Presidential crypto ethics and stablecoin rewards also remain active disputes.

Republicans are patching the coalition's perimeter while leaving its decisive fights for another round of negotiations. Their immediate task is to persuade senators who may oppose today's text to preserve the process for changing it.

A CFTC-side DeFi patch

The new CLARITY Act draft is labeled an “amendment in the nature of a substitute intended to be proposed”. Its table of contents expands Section 20209 from the July draft's “Software developer protections” to “Software developer protections and non-decentralized finance trading protocols.”

That addition creates a CFTC-side framework for determining when a nominally decentralized protocol still has a controlling party subject to intermediary rules.

Section 10301 already instructed the Securities and Exchange Commission to address a “non-decentralized finance trading protocol,” while the revised Section 20209 gives the CFTC a corresponding assignment.

The operative distinction is control: describing a venue as decentralized would not necessarily keep intermediary obligations from attaching when an identifiable person or group administers it.

The July substitute already made one Section 20209 protection for administering a DeFi protocol or liquidity pool specific to spot transactions, so EHF26718's verifiable development adds a CFTC framework for controlled protocols.

In July, 12 Democratic senators warned that broad DeFi exemptions could shelter blockchain prediction markets from derivatives rules. They asked negotiators to limit any new exemption to spot-market provisions, preserve the Indian Gaming Regulatory Act and Tribal-state compacts, and prohibit CFTC registrants from offering sports wagers and casino-style contracts.

A CFTC test for controlled protocols addresses part of that concern by making it harder for a centrally controlled venue to obtain a regulatory pass through a DeFi label. The senators also asked for protections extending beyond protocol classification, leaving Tribal sovereignty and the treatment of event contracts in play.

Sens. Lisa Murkowski and Brian Schatz have separately urged the CFTC to consult Tribes and respect federal Indian gaming law as it considers prediction-market rules.

The revision can make those lawmakers easier to approach. As of Sept. 10, none of the July letter's signers had publicly attributed a change in position to EHF26718.

The coalition math is still unforgiving

Under the Senate's cloture rules, ending debate on a legislative motion requires 60% of the full Senate, or 60 votes when there are no vacancies. With 53 Republicans, perfect party unity leaves at least seven votes to find elsewhere.

The National Sheriffs' Association has already shown how a targeted concession can alter the coalition's perimeter. On Sept. 3, the group moved from opposition to a neutral position after changes addressing illicit-finance concerns.

The clearest public threat inside the Republican conference remains ethics. Semafor reported that Sen. Thom Tillis said the bill could fail unless the White House helps bridge the standoff over restrictions tied to public officials' crypto interests, while Sen.

Mike Rounds expressed pessimism about the bill's prospects. Their comments signal danger rather than a verified whip count, but they also expose the weakness in assuming all 53 Republicans will vote for cloture.

Stablecoin rewards form another coalition-level pressure point. The sponsors' section-by-section summary says permitted rewards may be tied to activities such as opening an account, making payments, and providing liquidity.

Banks argue that those programs can function like interest and pull deposits from the regulated banking system.

That dispute has moved into a public lobbying campaign, as crypto groups launched a late advertising push accusing banks of trying to eliminate stablecoin rewards.

The same constraint applies to the calendar. A floor date forces choices but leaves subsequent votes and potential reconciliation ahead, and September's Senate window was narrow. A successful motion to proceed would preserve that path and move the unresolved issues onto the floor.

A vote to keep negotiating the CLARITY Act

Witt's argument supplies the White House's bridge between an unfinished bill and a 60-vote procedural threshold. In his telling, senators should advance the measure because a failed motion to proceed would deny both parties the opportunity to seek amendments.

Holdouts may decide that withholding cloture gives them more leverage, or that the remaining ethics, stablecoin and Tribal-policy gaps are too large to defer.

Republican negotiators are simultaneously giving those senators a revised text to evaluate. The controlled-protocol framework and the sheriffs' shift to neutral show that discrete objections can move even while the central bargain remains open.

The strategy requires 60 senators to accept the distinction between continuing the process and approving the product.

Cloture would carry the ethics, stablecoin, and prediction-market fights into another round of amendments. Failure would end that strategy before the unfinished compromises reach the floor.
