*Polymarket's contract on the CLARITY Act being signed into law in 2026 sat at about 18%, on roughly $9.9 million traded, as of August 25, resolving January 1, 2027. That's well down from 82% earlier in the year and back within the roughly 10% to 20% range seen since Thune filed cloture. The Senate opened the first procedural stage on August 8, adjourned without a floor vote, and cloture is now set for September 15.*

*Most coverage stops at that number. The odds move daily, but the bill's mechanics are what stick around.*

### **Key Takeaways**

- Polymarket's CLARITY Act 2026 enactment odds sit at about 18% as of August 25, down from 82% earlier in the year.
- The Senate's September 15 vote is on cloture, not final passage, needing 60 votes total.
- CLARITY splits oversight between the SEC (capital raising) and CFTC (spot market trading).
- A "mature blockchain system" test decides which coins count as commodities versus securities.
- XRP has a visible problem under that test since Ripple's escrow holds about 32.3% of supply.
- Fed Chair Kevin Warsh speaks at Jackson Hole on August 28, just before the Senate vote.

## **What Happened in the Senate**

Thune filed the cloture motion on the motion to proceed just before the chamber left town, [setting up a procedural vote](https://www.theblock.co/news/regulation/2026-08-08-majority-leader-thune-files-cloture-on-clarity-act-setting-up-sept-15-senate-vote-411211) at 2:15 p.m. ET on September 15, the day after senators return.

### **The Vote Count**

Republicans hold 53 seats, so the motion needs at least seven Democrats or independents to get to 60 votes. The bill already has real momentum behind it. The House passed its version 294-134 back in July 2025, and the [Senate Banking Committee](https://www.coindesk.com/policy/2026/08/06/senate-won-t-vote-on-crypto-clarity-act-before-its-summer-break) advanced a companion bill 15-9 in May.

The sticking points since then have been almost entirely about ethics provisions, stablecoin yield rules, and how much oversight authority goes to which agency, not about whether market structure legislation is needed at all.

### **What September 15 Actually Decides**

It's worth being precise here. Cloture on a motion to proceed doesn't pass the bill. It doesn't even start floor debate on the substance. What it does is end debate on whether to begin debating H.R. 3633 at all, which sounds almost absurd written out but is how Senate filibuster rules work.

If it clears, the bill moves to formal consideration and amendments. If it fails, the whole thing stalls again, and given how crowded the calendar gets once midterm campaigning ramps up, a failed vote here would push any resolution well into 2027.

| Date | Event |
| --- | --- |
| July 2025 | House passes CLARITY Act, 294-134 |
| May 2026 | Senate Banking Committee advances companion bill, 15-9 |
| August 8, 2026 | Thune files cloture; Senate adjourns for recess |
| September 15, 2026, 2:15 p.m. ET | Cloture vote on motion to proceed |
| After cloture (if passed) | Formal debate and amendments begin |

## **What the CLARITY Act Does: SEC Versus CFTC**

Strip away the politics and the bill is fundamentally a turf agreement between two regulators that have spent years arguing over jurisdiction.

### **The SEC's Role**

The SEC keeps its authority over investment-contract sales and capital raising, and gets a new exemption letting projects raise up to $75 million over twelve months without the full securities registration process. That's meant to give smaller projects room to fund development without treating every token sale like an IPO.

### **The CFTC's Role**

The CFTC comes out with something bigger: exclusive oversight of spot markets in digital commodities. The bill creates three new registered categories [under CFTC jurisdiction](https://xbtfx.com/blog/sec-advances-crypto-regulation/), digital commodity exchanges, brokers, and dealers, all of which have to join the National Futures Association.

Firms get 270 days after enactment to register provisionally. Once registered, they're on the hook for customer asset segregation, qualified custodians holding client funds, and retail disclosures that spell out an asset's maturity status before someone buys it.

None of this is exotic by traditional finance standards. It's roughly the same architecture that already governs commodities and securities elsewhere. The reason it's taken this long to [write into crypto law](https://www.yahoo.com/news/politics/articles/senate-keeps-clarity-act-alive-163302247.html) is that classifying a given token as one or the other has never had a clean legal test, which brings up the part of the bill that actually matters to anyone holding these assets.

|  | SEC | CFTC |
| --- | --- | --- |
| Jurisdiction | Investment-contract sales, capital raising | Spot markets in digital commodities |
| New provision | Exemption for raises up to $75M over 12 months | Three new registered categories: exchanges, brokers, dealers |
| Registration requirement | Existing securities framework | Provisional registration within 270 days of enactment |
| Compliance obligations | Standard securities disclosure | Asset segregation, qualified custodians, maturity disclosures |
| Industry body | N/A | Registrants must join the NFA |

## **The Mature Blockchain System Test**

This is the hinge the whole framework turns on. Whether a token gets treated as a digital commodity, and therefore falls under the CFTC's lighter-touch spot market rules instead of SEC securities rules, depends on passing a "mature blockchain system" test.

### **The Four Criteria**

[The bill lays out four requirements](https://www.congress.gov/bill/119th-congress/house-bill/3633): open-source code, transparent and pre-established rules for how the network operates, functional utility beyond speculation, and no single entity or address holding 20% or more of supply in a way that lets it control the network. That last criterion is where things get uncomfortable for a few major assets.

Bitcoin sails through without much argument. Ethereum and [Solana](https://xbtfx.com/blog/solana-mining-what-traders-and-investors-need-to-know/) sit in genuinely contested territory that lawyers will be litigating for years regardless of how this vote goes.

XRP is the one with the clearest problem on paper. Ripple's escrow sitting at roughly 32.3% of total supply is close to the textbook definition of the concentration the test was written to flag. That doesn't mean XRP automatically gets classified as a security under CLARITY, since the SEC's own prior litigation history with Ripple complicates the picture, but the bill's own language points at exactly the structural feature critics have raised about the token for years.

| Asset | Open-source/transparent rules | Functional utility | Concentration under 20% | Likely classification |
| --- | --- | --- | --- | --- |
| Bitcoin | Clears easily | Established store of value / payments | No single holder near threshold | Mature digital commodity |
| Ethereum | Clears easily | Broad smart contract usage | Disputed, foundation and large holders debated | Likely mature, argued over |
| Solana | Clears | Growing but concentrated validator set | Disputed, insider allocations a sticking point | Contested |
| XRP | Clears on code | Payments and settlement use case | Fails, Ripple's escrow holds ~32.3% of supply | Visible problem under the test |
| A generic new Layer 1 token | Depends on project | Depends on adoption | Usually fails at launch, founder/treasury holdings concentrated | Securities treatment likely at launch |

## **Jackson Hole and the Payments Policy Backdrop**

Here's a connection almost nobody covering either story separately is going to make.

### **A Fed Speech Eighteen Days Before the Vote**

The Federal Reserve holds its annual [Jackson Hole symposium](https://www.kansascityfed.org/research/jackson-hole-economic-symposium/) August 27 to 29, and this year's theme is financial innovation, specifically its implications for payments and policy. Kevin Warsh, who took over as Fed Chair from Jerome Powell in May, gives his first symposium address in that role on August 28, eighteen days before the Senate votes on crypto market structure.

| Date | Event | Why it matters here |
| --- | --- | --- |
| August 27–29, 2026 | Fed's Jackson Hole symposium, theme: financial innovation and payments policy | Sets the tone on digital payment rails right before CLARITY comes to a vote |
| August 28, 2026 | Kevin Warsh's first symposium address as Fed Chair | First real signal of how the new Fed leadership views crypto and stablecoins |
| September 15, 2026 | Senate cloture vote | Comes just 18 days after Warsh's speech |

Crypto reporters aren't watching Jackson Hole closely, and [monetary policy](https://xbtfx.com/blog/fiscal-policy-vs-monetary-policy-how-they-affect-markets/) writers aren't tracking CLARITY. But a Fed chair using his first major symposium speech to talk about payments innovation, right before Congress votes on how digital assets get regulated, is not a coincidence anyone should ignore.

Whatever tone Warsh sets on stablecoins, tokenized settlement, or the Fed's own posture toward digital payment rails could shape how undecided senators frame their votes two and a half weeks later.

## **Is Polymarket Legal in the US?**

Polymarket US operates through QCX LLC as a CFTC-regulated designated contract market after Polymarket's 2025 acquisition of QCEX; the international platform is separate and is not CFTC-regulated. That regulatory path is itself part of the broader story CLARITY is trying to formalize for the rest of the digital asset industry, prediction markets included.

|  | Before 2025 | After 2025 |
| --- | --- | --- |
| US access | Blocked for US users, offshore only | Polymarket US operates through a separate U.S. entity |
| Regulatory basis | None, unregulated offshore platform | Polymarket US: CFTC-regulated designated contract market; international platform separate |

## **FAQ**

**What are the current Polymarket odds on the CLARITY Act?**

About 18% as of August 25, 2026, down sharply from 82% earlier in the year and back within the roughly 10% to 20% range seen since cloture was filed.

**What does the September 15 vote actually decide?**

Whether to end debate on the motion to proceed, not final passage. It needs 60 votes, meaning at least seven Democrats or independents alongside all 53 Republicans.

**Does CLARITY reclassify XRP as a security?**

Not automatically, but Ripple's escrow holding roughly 32.3% of supply conflicts with the bill's 20% concentration threshold for "mature" digital commodities, which is a real point of exposure under the test as written.

**Is Polymarket legal to use in the United States?**

Polymarket US does, through QCX LLC d/b/a Polymarket US, a CFTC-regulated designated contract market. The international platform is separate and is not CFTC-regulated.
