SEC Regulation Crypto Assets: 55 letters, none from the sector

The SEC public file on Regulation Crypto Assets gathered 58 entries as of September 13, 2026, and none of its 55 letters were signed by a major crypto sector firm. Coinbase, Digital Asset, Inc. (the company behind Canton Network), and The Digital Chamber do appear in file S7-2026-27, but through a different route: three meeting memoranda—the one-page minutes with which the SEC (Securities and Exchange Commission) records that its staff has met with outside parties—published on August 20, August 27, and September 2, 2026. A federal rule is commented on through two distinct channels, each leaving a different trail, and with the window open until October 20, the distribution between the two can be measured while the deadline is still active. Here is the file breakdown entry by entry, compared with two others from the same agency, using a documented counting method so anyone can replicate it.

What is SEC file S7-2026-27 and how long is the comment period?

The SEC announced Regulation Crypto Assets on August 18, 2026, and the text appeared in the Federal Register—the official journal of the United States federal government—on August 21, 2026, spanning 146 pages, from 54510 to 54655. The proposal carries references 33-11434 and 34-106150, file number S7-2026-27, and RIN 3235-AN38 (Regulation Identifier Number, the code used to track a rule throughout its processing). The deadline for comments expires on October 20, 2026.

The rule proposes two registration exemptions—up to $5 million over four years and up to $75 million in each twelve-month period—plus a conditional safe harbor: a provision that protects the issuer from registration if specific conditions are met. We previously broke down the safe harbor and the $5M and $75M thresholds when the SEC announced it; here the focus is on who is commenting and through which channel.

The comment file is the part of the procedure that remains in writing. Everything submitted there—letters, attachments, meeting minutes—becomes part of the administrative record, which is the material used to later judge whether the agency considered the input received, according to Section 553 of Title 5 of the United States Code, the law governing how federal regulations are approved. A court reviewing the rule works based on that record and the agency's response within it.

Anyone can comment until October 20, 2026, by writing to rule-comments@sec.gov with "S7-2026-27" in the subject line; each submission is published with the name and content.

Who signed the 55 letters for Regulation Crypto Assets?

The 55 letters as of the September 13, 2026 cutoff are distributed among individuals with no declared organization, founders of small companies, and some professionals signing with their titles. Among the signatures with an underlying entity are Adamson Brothers/Directly Listed, Rivetz Corp., the firm Moschetti Syndication Law PLLC, and Sovereign Stack Initiative, which signed two letters on August 23 and 27, 2026; seventeen other small entities of the same profile follow. There is also an economics PhD candidate from Ariel University who signed declaring his affiliation, and three entries from August 28, August 29, and September 11, 2026, submitted as "Anonymous."

What is missing from that list: any letter from Coinbase, Circle, Kraken, Ripple, a16z (Andreessen Horowitz), Paradigm, Blockchain Association, The Digital Chamber, Crypto Council for Innovation, traditional market trade associations (SIFMA, the Investment Company Institute), the financial watchdog NGO Better Markets, state securities regulators (NASAA), or the broker supervisor (FINRA). Nor are there any from banks, exchanges, or major law firms.

Outside of those 55 entries, the SEC groups seven identical campaign letters under the "Type A" label in a separate 199-page PDF; the listing shows them in a single summary row above the table, which is why they do not add to the count of 58. This is the only coordinated block in the file. The first is dated August 27, 2026, and is signed "on behalf of global retail participants." They call for real-time reporting of the Consolidated Audit Trail, one-to-one verified custody for tokenized instruments, and strict pre-borrow—locating the security before short selling it. Most of those 199 pages consist of a chronology of the financial system that does not address the specific regulatory language.

What do the three SEC meeting memoranda regarding S7-2026-27 contain?

The three memoranda occupy one page each—96, 91, and 136 words. They state who met with whom, on what day, and that the conversation concerned the Regulation Crypto Assets proposal—"among other things" in two of the three; The Digital Chamber's memo does not use that phrase. They do not record positions, summarize arguments, or include attachments with presentation materials. What they do record by full name is who was in the room.

Staff counts are minimums, not exact figures: the memoranda use "including" when listing SEC attendees. With that caveat, the September 2, 2026 meeting with Coinbase stands out from the other two: nineteen people from the SEC and seven from Coinbase, with five agency units in the room—Corporation Finance, Trading and Markets, Economic and Risk Analysis, the Office of Public Affairs, and the Crypto Task Force.

The August 19, 2026 meeting with The Digital Chamber took place the day after the announcement of the proposal (August 18) and two days before its publication in the Federal Register; the memorandum titles it a "briefing." The August 26, 2026 meeting with Digital Asset, Inc. brought together six people from Corporation Finance and two from the Crypto Task Force with three representatives from the company that operates Canton Network.

How does a public letter differ from a meeting with SEC staff?

Both routes enter the same file and both are public. What changes is what is written down and when.

• Content. The letter is published in full: arguments, proposed alternative wording, figures. The meeting memorandum records attendance and the subject matter, and nothing more. From the September 2, 2026 meeting with Coinbase, we know who attended, not what was requested.
• Timing. Letters tend to cluster at the end of the period. Meetings happen earlier: the three in this file are from August 19, August 26, and September 2, 2026—that is, within the first month of a two-month window.
• Interlocutor and subsequent use. The letter goes to the secretariat, is archived, and remains available for another commenter to rebut or for a court to rely upon. The meeting puts the staff drafting the final text directly in front of the participants—on September 2, this included economists from Economic and Risk Analysis, who sign the cost-benefit analysis—and leaves nothing to rebut.

The fact that the SEC is regulating crypto through rulemaking instead of waiting for legislation has its own history, which we covered in the agency's plan B in the face of the stalled CLARITY Act.

How does the crypto file compare to two other SEC files?

Three proposals from the same agency, counted on the same day using the same method. The windows are not aligned, and the Trade-Through Rule window has already closed.

Two warnings regarding that table. Files S7-2026-25 and S7-2026-20 each include one "Staff Study" entry, which is neither a letter nor a memorandum and is therefore excluded from the last two columns. Furthermore, the distribution is based on the type label assigned by the SEC itself: in S7-2026-20, two meeting memoranda—those from the August 26, 2026 meetings with The Nasdaq Stock Market and Penserra Securities—are labeled as Public Comment, so when counted by content, there are 13 memoranda and 168 letters.

The Trade-Through Rule, a microstructural reform of the stock market, ended with 182 entries: 171 within its 62-day window and 11 published after the close. Regulation Crypto Assets had 57 entries in its first 27 days, as of September 13, 2026, with 37 days remaining.

Why the absence of sector letters in September does not prove lack of interest?

Because the same public record shows where those letters end up: on the final day. In file S7-2026-20, which expired on August 17, 2026, 102 of the 182 entries are dated between August 11 and August 17, 2026—56.0% of the total in the final seven days. On the closing day alone, 56 entries arrived, 30.8% of the entire file. The day before, only 3 had arrived.

And among the signatures from that August 17, 2026, are precisely the organizations that have not signed any letters in the crypto file: Coinbase Global, Inc., Blockchain Association, a16z, Crypto Council for Innovation, Digital Asset Holdings, and Douro Labs alongside the Hyperliquid Policy Center, in addition to SIFMA, Better Markets, Citadel Securities, NYSE Group, Goldman Sachs, and Jane Street. All regarding a stock microstructure rule, all on the expiration day. That these same organizations are pushing simultaneously in Congress and at the agency is the backdrop for the Washington levers that the market has been pricing in for months.

Scott Bauguess, VP of global regulatory policy at Coinbase, signed the Coinbase Global, Inc. letter to file S7-2026-20 dated August 17, 2026, and appears among the attendees in the memorandum for the September 2, 2026 meeting on S7-2026-27. Both entries are public and recorded in his name; neither says what he requested.

With 37 days until the close, as of September 13, 2026, the sector appears in the crypto file via meeting memoranda; their signature is not yet on any letter. If the Trade-Through Rule pattern repeats, those letters will exist and will be dated in October. What is already measured, and does not depend on what happens next, is the sequence: on day 27 of the 64 between announcement and close, the only recorded sector contact is a meeting, and no letter—from them or anyone else—yet carries an institutional signature.

How many entries will file S7-2026-27 have on October 20, 2026?

The file curve has a recognizable shape: an initial peak and a descending plateau.

Internal calculation based on dates published by the SEC, with a single declared assumption: counting from August 18, 2026, the day of the announcement, until the September 13, 2026 cutoff, excluding the August 15 entry from the base as it was prior. Based on that:

1. From August 18 to September 13, 2026, 57 entries arrived in 27 days, an average of 2.11 per day.
2. The first three days account for 20 of those 57 entries, 35.1% of the base in 11% of the elapsed days.
3. From September 1 to September 13, 2026, 13 arrived in 13 days, a rate of 1.00 per day—52.6% below the period average. Six days in that stretch recorded zero entries: September 4 and 8 (workdays) and the weekends of September 5-6 and 12-13.
4. There are 37 days remaining from September 14 to October 20, 2026. At 2.11 daily, that would be 78 more entries.
5. Result: 57 + 78 = 135 entries dated from August 18, 2026. The counter on the sec.gov comments page will show 136, because it includes the August 15 entry.

That figure comes from a simple projection with the stated assumption: it is valid only if the average pace holds, and the Trade-Through Rule evidence suggests it will not. Published on September 14, 2026, it will be self-verified on October 21, and the gap between 135 and the actual count will measure the deadline effect.

How to count a file that sec.gov serves from cache?

The sec.gov comments page shows 30 rows and a pager, and query parameters are useless: ?page=1 or ?items_per_page=100 return byte-for-byte the same document as the clean URL—99,328 bytes on September 13, 2026—because it is served from cache and pagination happens in the browser. Anyone counting what they see on screen counts 30 and misses 28. The rest is obtained through the AJAX views endpoint of Drupal, the content management system on which sec.gov runs:

1. Download the file page declaring a User-Agent with a name and contact email. Without this, sec.gov returns a 403 due to request limits.
2. Extract the drupal-settings-json block from the HTML and, within it, the views.ajaxViews object. That object contains the table parameters: view_name=comment_letters_display, view_display_id=default_block, and view_args=1122211, which is the internal identifier for file S7-2026-27.
3. Perform a POST to https://www.sec.gov/views/ajax?page=N with those parameters in the body and the header X-Requested-With: XMLHttpRequest. The response is a JSON with insert commands containing the table HTML.
4. Space the requests by a few seconds and increase N until the response arrives with no rows.
5. The distribution by type comes from a label assigned by the SEC itself, which is not always accurate: in S7-2026-20, the memoranda for the August 26, 2026 meetings with Nasdaq and Penserra Securities are labeled Public Comment. Counting by content requires opening the PDFs.

With file S7-2026-27 as of September 13, 2026: the base page gives 30 initial rows, page=1 gives 28, and page=2 gives zero. Total 58, and the zero on the third page is what closes the count. Watch out for the extra row: above the table, there is a summary row that says "A: 7" and links to the campaign letters PDF, so on the base page, 31 rows are visible but only 30 are entries. The same procedure works for any agency file by changing the view_args, which can be read in the HTML of each page.

The method depends on an internal view that the SEC does not document and may reconfigure without notice: if comment_letters_display or the view_args change, the drupal-settings-json of the page must be re-read.

The date shown in the listing is also not the publication date. A letter dated August 31, 2026, and another dated September 10 did not appear in the September 11 query and appeared before the 13th, so the count for a past day can increase later. This is why each count carries its cutoff date.

A warning about two figures that get mixed up. The large figure circulating comes from the proposal itself: on page 20 of document 33-11434, the SEC writes that "to date, the Crypto Task Force has received over 300 comment letters," and note 62 clarifies that all references to comment letters in the text point to that inbox, a list separate from the file for this rule. That inbox, open since 2025 regardless of any specific proposal, had 350 entries counted with the same method on September 13, 2026. File S7-2026-27 had 58. They are two different metrics and are not added together.

What is worth watching in the file before October 20, 2026?

Between September 14 and October 20, 2026, the date of any institutional letters that appear and the gap between the 135 projected entries and the actual count on October 21 will resolve themselves. Two other things require a close look at the file:

1. How many more meeting memoranda are published. Three in the first 27 days of the window, as of September 13, 2026, is the starting pace. The contrast is in file S7-2026-20, which accumulated 13 memoranda counted by content, 9 of them within the window, with recorded meetings from BlackRock, Citadel, Nasdaq, Charles Schwab, and UBS, among others.
2. If any meeting moves up in level. The three memoranda published as of September 13, 2026, are from division staff. In the Trade-Through Rule file, there are memoranda signed by the office of a commissioner, Hester M. Peirce. That is a record of a different category.

The 55 letters in this file are almost all from individuals and small companies who put it in writing, while the three large organizations that appear do so only via meeting memoranda. Both count in the procedure; only one can be read.
