Nasdaq Wants a 15% 'Buffer' in Crypto Trust Funds — and a New Definition for 'Digital Commodity'

On June 16, 2026, the SEC published a notice that does two things at once: it solicits comment on a Nasdaq proposal to rewrite part of its crypto-trust listing rule, and it designates a longer period for the Commission to act. The underlying document is Nasdaq's Amendment No. 1 to a proposed rule change amending Rule 5711(d) — the generic listing standards for Commodity-Based Trust Shares. Read past the procedural language and there are three concrete moves worth understanding, because together they would reshape what a Nasdaq-listed crypto trust is allowed to hold.

The first and most consequential change is a buffer. Under the proposal, up to 15% of a trust's net asset value could consist of assets that do not meet the eligibility criteria the generic standard otherwise imposes. Generic listing standards exist precisely so an exchange can list new products without filing a fresh rule change each time; the tradeoff is that everything inside the fund must clear a fixed bar. A 15% carve-out for non-conforming assets is a deliberate loosening of that bar — flexibility for fund sponsors, but also a wider aperture for assets that would not qualify on their own.

"The Exchange proposes to amend Rule 5711(d) to modify the generic listing standards for Commodity-Based Trust Shares (as defined below) to: (1) allow for a buffer of up to 15% of the net asset value (“NAV”) of the Commodity-Based Trust Shares holdings to consist of certain assets that do not meet the eligibility criteria under the generic listing standards; (2) add a definition for digital commodi[ty]..."— Nasdaq Amendment No. 1, SR-NASDAQ filing, source

The second move is definitional, and in regulatory drafting, definitions are where the leverage sits. The amendment adds "digital commodity" as a defined term. The choice of word is not accidental. "Commodity" carries jurisdictional weight — it gestures toward the CFTC's domain rather than the SEC's securities authority. By writing a specific "digital commodity" definition into an exchange listing rule, Nasdaq is drawing a line around which crypto assets it considers fair game for these trusts, and implicitly which regulatory bucket they fall into. The exact contours of that definition are the part comment letters will fight over.

Why the amendment matters more than the original filing

The record is explicit that this is a do-over. Nasdaq initially submitted the rule filing on April 14, 2026, and the amendment "replaces and supersedes the original filing in its entirety." The notice spells out exactly what changed: the amendment specifies what assets may be included in the 15% buffer, adds the "digital commodity" defined term, and adds provisions to allow for active management. That last item connects this proposal to the broader 2026 trend of crypto products moving from passive single-asset trusts toward managed, multi-asset vehicles. An exchange that wants to host actively managed crypto ETPs needs its generic standard to accommodate a manager's discretion — and a buffer plus an active-management provision is how you build that headroom into the rulebook.

It is worth being precise about what "supersedes in its entirety" means for anyone tracking this docket. The comment record on the original April filing is effectively reset; the Commission notes it received no comment letters on the original proposed rule change, and is now publishing the amended version to solicit comment anew. The clock is also reset: the SEC simultaneously designated a longer period for Commission action, the standard signal that it does not intend to rush a decision on a rule that broadens what crypto trusts can hold.

The structural stakes

Generic listing standards are quiet infrastructure. They rarely make headlines, but they determine how fast new products reach ordinary investors. A bespoke rule change for each crypto fund means months of SEC review per product; a permissive generic standard means a sponsor can list a conforming fund without that friction. The 15% buffer and the active-management provision push this particular standard toward the permissive end. That is good for product velocity and arguably good for competition among fund sponsors. It also means more of the investor-protection work shifts from the upfront listing decision to the ongoing surveillance and disclosure regime, because the gate at the door is being widened.

None of this is approved yet. The document is a notice of filing of an amendment and a designation of a longer period — procedurally, an early-to-middle station, not a destination. The SEC could approve, disapprove, or institute proceedings. What the document does establish, verifiably, is Nasdaq's intent and the precise mechanics of the change: a 15% non-conforming-asset buffer, a new "digital commodity" definition, and provisions to permit active management, all folded into Rule 5711(d) via an amendment that wiped out and replaced the original filing.

It is worth dwelling on what a 15% buffer does in practice, because percentages can hide their own significance. On a trust with a billion dollars in net asset value, a 15% buffer is a hundred and fifty million dollars that can sit in assets the generic standard would otherwise exclude. That is not a rounding error; it is a meaningful pool of discretionary, potentially less-liquid or less-vetted holdings inside a product marketed as a clean, rules-based vehicle. The amendment says the proposal would specify what assets may go into that buffer, which is the right instinct — an open-ended buffer would be far more troubling than a defined one. But the investor-protection question becomes: how tightly is the buffer's contents constrained, and what disclosure tells a shareholder how much of their fund is riding in the non-conforming sleeve at any given time? Those are exactly the questions a generic standard has to answer well if it is going to be permissive, and they are the ones a careful comment letter will press.

For readers, the takeaway is to watch the comment file and the definition language, not the press treatment. The headline version of this story is "Nasdaq eases crypto ETF rules." The document version is more specific and more useful: Nasdaq wants room to list managed crypto trusts that can hold a meaningful slice of otherwise-ineligible assets, and it is asking the SEC to bless a definition of "digital commodity" to draw the perimeter. Where that perimeter lands will shape what trades on the exchange for years.
