Senate Majority Leader John Thune filed cloture on the motion to proceed to H.R. 3633, the Digital Asset Market Clarity Act, on 8 August 2026, after confirming there would be no August floor vote before the recess. CryptoSlate and contemporaneous Senate coverage place the procedural test on 15 September 2026. Cloture here is a 60-vote gate to begin debate on the July 22 substitute text. It is not final passage, and the bill is not law.

How H.R. 3633 got to a September cloture date

The House passed its Clarity vehicle in July 2025. In the Senate, the Banking Committee advanced a market-structure draft on 14 May 2026 by a 15–9 bipartisan vote, a timeline Senator Cynthia Lummis recited when she released the merged substitute. On 22 July 2026, Lummis published an amendment in the nature of a substitute for H.R. 3633 that combines the Banking Committee’s SEC and banking titles with the Agriculture Committee’s CFTC digital-commodity titles, plus illicit-finance, DeFi, banking, customer-protection, and ethics divisions. Her office also posted a section-by-section of that same draft.

NYDIG’s 24 July read put the merged PDF at roughly 616 pages and stressed the political math: with a handful of Republican holdouts possible, leadership still needs a credible path to 60 votes, not a simple majority. Seven Democrats often named as coalition targets publicly said the Republican proposal “falls short” on ethics, consumer protection, and illicit finance. Thune’s early-August cloture filing preserved a September window instead of forcing a cold restart after recess.

Status, stated plainly: the operative Senate text for scoring is the 22 July 2026 Lummis substitute. Floor managers can still rewrite it by amendment if cloture succeeds. Nothing in that PDF binds markets until Congress enacts a conference product and the President signs it.

What the July 22 substitute actually does

Division A, Title I draws the SEC side of the map around ancillary assets (network tokens whose value depends on entrepreneurial or managerial efforts of an originator). Sec. 10102 requires initial and semiannual disclosures for covered transactions. Sec. 10103 directs the SEC to adopt an exemption the draft calls Regulation Crypto: an ancillary-asset originator may raise the greater of $50 million in gross proceeds per calendar year for up to four years, or 10% of the dollar value of outstanding ancillary assets, and may not raise more than $200 million total in reliance on that exemption, while meeting the disclosure track. Tokens themselves are treated as commodities once the investment-contract layer is handled under those rules. Originators or intermediaries can also certify that essential managerial efforts have ended, which stops the ongoing SEC disclosure clock under the draft’s terms.

Division B, the Digital Commodity Intermediaries Act, is the CFTC half. It creates federal registration for digital commodity exchanges (DCEs), brokers (DCBs), dealers (DCDs), pool operators, trading advisors, and qualified digital asset custodians (QDACs), with core principles on surveillance, segregation, disclosures, and system safeguards (secs. 20204–20208 in the section-by-section). Spot digital-commodity markets get a dedicated federal home they have lacked outside fraud and manipulation cases.

Self-custody is written in twice. Sec. 20216 defines a self-custodied digital asset as one whose owner keeps exclusive control of the private keys without a third-party custodian. Sec. 10605, the Keep Your Coins Act, says a federal agency may not prohibit, restrict, or impair a covered U.S. individual’s ability to self-custody with a self-hosted wallet for lawful purposes, while preserving BSA, sanctions, and other illicit-finance enforcement. Separately, Sec. 10307 lets Treasury issue guidance for institutions that touch self-hosted wallets, but that guidance may not generally require collecting personally identifiable information on a wallet controller who is not both the institution’s customer and a party to the transaction (sanctions and lawful process excepted).

DeFi and software. Title III distinguishes non-decentralized trading protocols (control, discretion, or ability to alter or censor operations) and points SEC/Treasury rulemaking at those controlled front ends, not at pure protocol code. Division B Sec. 20209 exempts specified developer activities (publishing software, validating, non-custodial wallets, user interfaces) from CFTC registration while keeping anti-fraud and anti-manipulation authority.

Stablecoin yield. Sec. 10404 of the July 22 text prohibits paying interest or yield on payment stablecoins in the manner the draft restricts. Payment stablecoins themselves remain a GENIUS Act product; Clarity is the market-structure companion, not a rewrite of the July 2025 stablecoin statute we tracked at the one-year rulemaking checkpoint.

Ethics (Division C). Secs. 30101–30102 ban certain digital-asset transactions by covered officials and set related ethics requirements. That block is the loudest coalition fight in the July–August coverage: Democrats want stronger enforceable limits; some Republicans resist the breadth. It is also the section most likely to move if managers cut a deal before or after cloture.

Who feels this outside Washington

For U.S. intermediaries, Clarity is a licensing and books-and-records bill: which desk is an SEC digital-asset intermediary, which venue is a CFTC DCE, where customer assets must sit in a QDAC, and how BSA treatment attaches to digital-commodity brokers and exchanges (Sec. 10201).

For token projects, the practical delta is the Regulation Crypto fundraising box and the ancillary-asset disclosure cycle, not a promise that every token is forever outside securities law. Primary raises that touch U.S. persons would live inside those caps and filings if the statute lands roughly as drafted.

For LatAm builders and users, the bill does not rewrite Pix, SPEI, Bre-B, or local VASP registries. The regional hook is secondary and real: teams that raise from U.S. investors, list on U.S.-touching venues, or ship dollar tokens through GENIUS-permitted rails inherit whatever SEC–CFTC map Congress locks in. Argentina’s CNV PSAV track and Brazil’s BCB SPSAV file-by-30 October 2026 deadline (Resolução BCB nº 520) are separate local regimes; Clarity is the U.S. overlay on capital formation and spot commodity trading. Dollar stablecoins that already dominate LatAm payments still run first through GENIUS implementing rules, including the CIP fight over direct issuer redemptions that landed in August comment letters.

While the Senate calendar slipped, the SEC on 18 August 2026 proposed Regulation Crypto Assets as agency exemptions and a safe harbor. That package can move on a comment clock even if H.R. 3633 stalls; it cannot grant the CFTC the full spot digital-commodity registration scheme Division B would create. CFTC Chair Michael Selig said on 20 August, per CryptoSlate, that the agency would start taking market steps under existing authority if Clarity kept stalling. Agency work is a partial substitute, not a statute.

What 15 September actually decides

A successful cloture vote lets the Senate proceed to H.R. 3633. It does not enact the July 22 text. Failure leaves leadership looking at a thin autumn calendar before election recess, with midterms in November. Even a yes vote implies amendment fights, a possible second cloture, House-Senate reconciliation, and a signature before anything is operative. The draft’s own effective-date pattern (roughly 360 days after enactment for many provisions, later for some rulemakings in the section-by-section) means product and compliance builds would still have a runway after any signing.

If you operate a U.S.-facing exchange, broker, or custodian: map your activities against the DCE/DCB/DCD/QDAC vocabulary and the ancillary-asset disclosure track, and treat both as draft until enacted text exists.

If you raise or advise on a token sale that may touch U.S. persons: read Sec. 10103’s dollar caps and disclosure conditions in the July 22 PDF, and compare them to the SEC’s separate August proposal. They are not the same instrument.

If you hold keys yourself: the Keep Your Coins and self-custodied-asset language is protective on paper and still subordinate to BSA and sanctions enforcement. Do not read a draft section as a live shield.

This is a reading of a filed cloture path and a published substitute amendment, not legal, tax, or investment advice. Verify operative wording on the Lummis July 22 substitute, the section-by-section, and the congress.gov bill page for H.R. 3633 before you change a product plan.

Takeaway

H.R. 3633 reaches a 15 September 2026 Senate cloture vote on the motion to proceed after Thune’s 8 August filing. The scored text is Lummis’s 22 July 2026 substitute: SEC-side ancillary-asset disclosures and a Regulation Crypto raise box ($50 million per year / four years, $200 million lifetime cap in the draft), CFTC-side digital-commodity intermediary registration, explicit self-custody protections, and an ethics title that still divides the coalition. Sixty votes only open the floor. Watch whether managers cut an ethics deal, whether the July 22 dollar caps survive amendment, and whether agency rulemaking fills gaps if the calendar runs out.
