The Senate's cloture vote on the CLARITY Act lands September 15, and prediction markets currently put the odds of clearing the needed 60 votes at just 13-29%, down from roughly a quarter a week earlier. If it fails, the question that matters isn't whether crypto regulation stops — it's what CFTC crypto rules Clarity Act supporters spent two years trying to legislate now show up as instead, drafted by an agency rather than passed by Congress.

The answer already exists in outline form. On August 20, CFTC Chair Michael Selig directed staff to draft crypto market-structure rules using the agency's existing derivatives-law authority, explicitly framed as the contingency plan if CLARITY stalls in the Senate. That directive is the only concrete answer in the public record right now to "what replaces CLARITY," and it's worth understanding exactly what it does and doesn't cover.

The CFTC crypto rules coming if the Clarity Act fails

Selig's plan has two distinct pieces, and conflating them is the easiest way to misread this story. The first is a new designated contract market (DCM) subtype — call it a "crypto asset market" — that would let both registered and currently unregistered exchanges offer leveraged and margined crypto trading onshore in the US. That's a real, executable regulatory lane: it doesn't require new legislation, just a rulemaking under authority the CFTC already has over derivatives.

The second piece is vaguer and more consequential in the long run: instructions to "engage with" developers of onchain protocols — decentralized exchanges and lending platforms that aren't companies in the traditional sense — to pull them into some version of the same regulatory box. Trump has already named Hyperliquid, the largest onchain perpetuals exchange, as a protocol Selig is working to bring into US compliance. There is no defined line yet between "software" and "regulated marketplace," which is exactly the kind of ambiguity that invites years of litigation rather than months of compliance.

What does the new rule actually let exchanges do?

For a US-based or US-facing exchange, the DCM category matters because leveraged crypto trading has effectively lived offshore since the CFTC and SEC turf war made onshore listing too risky to attempt. A dedicated "crypto asset market" designation would give exchanges a defined path to list leveraged products domestically, under CFTC oversight, without waiting on Congress to pass a market-structure statute that assigns clear jurisdiction between the CFTC and SEC.

That's meaningfully narrower than what CLARITY was designed to do. CLARITY would have created statutory definitions — distinguishing a "digital commodity" from a security, assigning primary oversight, and giving both agencies and industry a durable rulebook that survives a change of administration. An agency rule built on existing authority does none of that. It only reaches activity the CFTC can already plausibly claim to regulate, meaning derivatives and leveraged trading. Spot markets, token issuance, and the broader question of when a crypto asset is a security stay unresolved, because those questions run through the SEC, not the CFTC — and the SEC is pursuing its own separate track, a safe-harbor rule for issuers running through an October 20 deadline.

Why Hyperliquid is the real test case

The DeFi outreach is where this fallback gets legally shaky. The CFTC's authority has historically covered derivatives contracts and the intermediaries that trade them — not open-source software that anyone can run without a company behind it. Hyperliquid doesn't have a CEO who can register with the CFTC in the way a traditional exchange does; it's a protocol. Selig hasn't specified which existing statute gives the agency jurisdiction to regulate that kind of decentralized infrastructure, and that gap is precisely the kind of question courts have used the "major questions doctrine" to strike down in other agencies' rules — the principle that agencies can't claim sweeping new authority over an entire industry without clear congressional authorization.

So while Trump's comments frame Hyperliquid's US entry as a matter of when, not if, the mechanism for getting there doesn't exist yet. It's outreach, not a rule, and the more likely near-term outcome is that the exchange-side DCM category advances while the DeFi piece stays stuck in talks.

Who wins and who loses

The winners, if this plan moves forward, are US-registered derivatives exchanges and CFTC-regulable trading venues — they get a same-year path to onshore leveraged crypto products without needing Congress to act, something CLARITY's failure would otherwise have denied them entirely. Selig's CFTC also wins in the sense that it keeps the agency relevant and in front of the policy conversation regardless of what the Senate does.

The losers are DeFi protocols and anyone hoping for durable, litigation-proof clarity. A rule built on existing agency authority can be unwound by the next CFTC chair the way a statute cannot — it's reversible in exactly the way CLARITY, as an act of Congress, would not have been. That instability is itself a cost: an exchange or protocol building compliance infrastructure around a rule that could disappear in four years discounts the value of complying at all.

Is this actually a substitute for CLARITY?

Not really, and the honest framing is that CLARITY's failure produces three disconnected pieces rather than one coherent law: a CFTC exchange rule, a separate SEC issuer safe harbor, and undefined DeFi outreach. Notice-and-comment rulemaking realistically takes months even once the CFTC formally proposes something, and nothing has been proposed yet — only directed. If cloture fails September 15, expect the CFTC framework to keep advancing procedurally regardless, but treat "replaces CLARITY" with real skepticism until an actual rule text appears in the Federal Register. The risk case Wyoming Senator Cynthia Lummis and others have already flagged — an extended regulatory vacuum stretching toward 2029-30 — doesn't go away just because the CFTC has a plan; it just gets one more disputed layer stacked on top of it.
