Treasury GENIUS docket: 161 letters and none from Tether

The U.S. Treasury docket regarding the rule implementing the GENIUS Act closed on Oct-20-2026 with 161 public letters, and the two signed by digital dollar issuers —Circle and Ripple— together account for 20.73 % of the supply measured on-chain. 76.95 % of that base, $182,550,760,688.22 of USDT out of a total measured $237,225,706,837.51, is issued by a single company, Tether, which appears neither by letter nor by meeting. An administrative docket (the public record of comments an agency opens before approving a rule) counts letters, one per signatory, without inquiring about the volume of capital each moves. By weighting each issuer by the dollars they have in circulation, the 161 letters reveal a distribution: who put their name forward, who did not, and how much digital dollar backing exists behind each response. This piece provides that breakdown and measures who is on record in the docket, not what each filing requests: we have not read the content of the 161 letters.

What closed on Oct-20-2026 in the Treasury docket regarding GENIUS?

On Aug-18-2026, the Treasury published its proposed rule on the issuance, offering, and sale of payment stablecoins —the term used by the law for digital dollars— across 24 pages of the Federal Register. A Notice of Proposed Rulemaking (NPRM) is the draft the agency submits for public comment before approving the final text, and the comment window lasted 62 days, from August 18 to October 19, Eastern Time.

The closing is recorded with two wordings that represent the same moment. The Federal Register prints "October 19, 2026," and regulations.gov records the end of the period at 03:59:59 UTC on October 20, which is one second before midnight on the U.S. East Coast. There is no discrepancy to resolve: it is one time written in two time zones.

In that closing day reading, the docket contains 161 public letters, 3 meeting summaries with Treasury staff, and 6 documents in total—the same 6 as on October 14. This means there was no extension, and precedent existed: note 16 of this same proposal recalls that the Treasury extended the 2025 advance notice period by fifteen days, until November 4 of that year. This time, the deadline was met as published.

Did Tether submit a letter or hold a meeting in the Treasury docket on the GENIUS rule?

Tether does not appear under its own name among the 161 letters in docket TREAS-DO-2026-0496 nor among the attendees of the 3 meeting summaries, according to the reading on Oct-20-2026. Identification is based on the name regulations.gov publishes in the title of each letter, and 28 of the 161 are anonymous and not attributed to anyone. Tether issues the $182,550,760,688.22 of USDT measured on-chain on the closing day, split between $88,302,623,529.98 on Ethereum and $94,248,137,158.24 on Tron: 76.95 % of the $237,225,706,837.51 total of the six measured issuers. The other two significant absentees are World Liberty Financial, which issues USD1, and Paxos, which issues PYUSD and USDG; neither is on record via letter or meeting.

The contrast lies in the scale of the only issuer that is on record via a meeting. On Oct-01-2026, Treasury staff met with representatives from The Digital Chamber and Société Générale, and the entity providing its opinion on the rule was the French bank, issuer of USDCV. That token measured $8,936,826.00 on the closing day, 0.0038 % of the base; six days earlier it measured $11,186,826.00. The measured supply of USDT is 20,427 times that of USDCV.

How is a docket signatory weighted by the dollars they issue?

A comment docket is a flat list. A letter from a private individual in Ohio and a letter from the American Bankers Association each occupy one line, with the same identifier and the same title format. This design is deliberate —administrative procedure does not rank signatories— but it means the count says nothing about the size of what is at stake for each party.

The way to weight them without inventing a weighting system is to query the contract. Each digital dollar runs on one or several contracts that publish how many units exist on that network; this is public data, without intermediaries or estimation. Summing this figure per issuer reveals how much digital dollar backing supports each signature in the docket. The universe, fixed on October 14, consists of fiat-backed stablecoins with an identifiable issuer and more than $1 billion in circulation according to DefiLlama on that date. There are six: USDT by Tether, USDC by Circle, USD1 by World Liberty Financial, PYUSD by Paxos and PayPal, RLUSD by Ripple, and USDG by Paxos. The base for these six on the closing day is $237,225,706,837.51, a CleanSky calculation.

This base covers 88.66 % of the $267,581,365,681.32 that DefiLlama attributes to the same six tokens. What we did not read were entire chains, and this cuts both ways: excluded are USDC on Solana ($7,021,615,654.32 according to the aggregator) and on Hyperliquid L1 ($6,927,503,130, same source), from an issuer that did sign, and USDT on BNB Chain ($9,176,953,588) and Solana ($2,692,610,502), from one that did not. We do not estimate how the share would look with the gap closed, because the two series are not the same metric.

The two series diverge in a measurable way. On Ethereum, the USDT contract declares $88,302,623,529.98 and DefiLlama attributes $72,895,130,064.76 to that same network; the difference is consistent with the authorized but unissued balance that Tether maintains in its treasury. For USDC, the spread is smaller: $47,725,807,743.58 in the Ethereum contract versus $44,300,170,644.84 from the aggregator. These are two different metrics for similar things, and the figures in this article are always the former—what the contract publishes.

Who signed the GENIUS docket and how much digital dollar is behind them?

The two issuer letters total $49,176,661,203.67 in measured supply, 20.73 % of the base of six. Including the two tokens from outside the universe, FDUSD and USDCV, the percentage is 20.71 %: the conclusion remains unchanged, and 20.73 % is the figure calculated on the universe as fixed on October 14.

Both letters bear a publication date of the closing day and are in the docket under the companies' names: that of Circle Internet Group and that of Ripple. What they request in them is not part of this measurement.

What changed in the Treasury docket in the six days prior to closing?

The 161 letters were published on 14 different days, and 84 of them appeared in the docket on October 20: 52.17 % of the public material was released on the closing day itself. Letters with an entity name in the title went from 14 to 57, multiplying by 4.07 in six days.

The measurement has a limitation that conditions this entire section. What is read in the API is posted, the date on which regulations.gov publishes a letter, not the date on which its author submitted it. To read the receipt date, a proprietary API key is required, and without it, there is no way to know how many of those 84 were written on the final day. The only letter for which we could see the detail was received on August 17 and appeared published on the 27th: a ten-day lag. And publication occurs in batches, not continuously: fourteen days of batches for 161 letters. Thus, "84 on the closing day" describes when 52.17 % of the docket became public, and nothing more.

This has a consequence for anyone using an administrative docket as a source. Whoever consulted it on October 14 —ourselves included— saw 46 % of the letters that would eventually be published, with a zero where there were later two issuers. The period for providing an opinion closes before the public can see what was opined upon.

Which entities wrote to the Treasury regarding the GENIUS rule?

A classification detail changes how the 57 letters with entity names, the 53 in an individual's name, and the 23 without classifiable format are read: the class is assigned by the title format published by regulations.gov. Thus, "Circle Internet Group, Inc." counts as an entity, while "Ripple," "Coinbase," or "Ledger" written plainly fall into the unclassifiable format bucket, and titles with commas —"Andreessen Horowitz (a16z)" or the joint letter from five DeFi organizations— end up classified as individuals. An anonymous letter is anonymous: no signatory is attributed.

Crossing the three classes, this is what is in the docket at closing, with names as published by the agency:

• Crypto issuers and platforms: Circle, Ripple, Coinbase, and Ethena Labs, plus M0 Labs.
• Banking, credit unions, and markets: American Bankers Association, Bank Policy Institute, Independent Community Bankers of America, and Securities Industry and Financial Markets Association, and ten more, including the joint filing by Custodia Bank and Vantage Bank Texas.
• Payments: Mastercard, Stripe, Electronic Transactions Association, and Money Services Business Association.
• Organized crypto and compliance: a16z, Coin Center, The Digital Chamber, and The Blockchain Association, and fifteen more, including Chainalysis, Ledger, and PTG Markets.
• Joint DeFi filing: DeFi Education Fund, Jump Crypto, Paradigm, Solana Policy Institute, and Uniswap Labs sign a single letter.
• Regulators: The New York State Department of Financial Services, dated October 5, and a joint filing by the four organizations of state regulators and legislators (CSBS, MTRA, NASCUS, and NCSL).
• Critical counterweight: Better Markets, Americans for Financial Reform Education Fund, Americans against Monopolies, and the Joint Center for Political and Economic Studies.
• Notable names: Congressman Warren Davidson, former SEC Commissioner Michael Piwowar, and economist Darrell Duffie, each with a letter in their name.

Two actors use both channels. PTG, the group of proprietary trading firms, met with the Treasury on September 15 and also submitted a letter, published on the closing day. The Digital Chamber accompanied Société Générale in the October 1 meeting and also has a letter in the docket. The same pair of names appeared in the parallel SEC docket on crypto assets, which closed on the same Oct-20-2026: in our October 14 reading, it accumulated 113 entries, 108 letters, and 5 meetings, figures we have not re-read on the closing day.

How many comments did the other GENIUS Act dockets receive?

The first six numbers are from the field the Federal Register pulls from regulations.gov, with verification dates ranging from November 2025 to October 2026, and have not been recounted by us; only the 161 is a proprietary reading from the closing day. This field can fall short: for this same docket, it marked 113 comments at 20:55:05 UTC on the closing day, 48 below the 161 returned by the API on the same day. The 257,601 from the OCC warrants caution above the others: it is of an order of magnitude unlike any other docket in this family, and we do not know how much of that consists of campaign filings, as we have not counted it.

With the figures as they stand, the 161 letters for this rule are one below the 162 in the AML and sanctions prevention docket, above the 70 for customer identification and the 61 for state regime equivalence, and far from the 396 of the 2025 advance notice and the 257,601 of the OCC issuance rule. This is the rule that determines who can issue a digital dollar in the United States and under what conditions, the block closed by the final GENIUS Act rules of July 2026, and its docket is the fourth most populated of the seven in the table.

What remains to be verified in the GENIUS docket after closing?

Three verifications remain pending, and all three have dates. The first is the receipt date of each letter, which requires a proprietary API key: with it, one would know how many of the 84 published on October 20 were submitted that day and how many had been waiting weeks for their batch. The second is to recount on October 28, because with a measured ten-day lag, the total of 161 could rise without anyone having written anything new after closing. The third is the 2025 advance notice, to see if the same issuers missing today were already missing then.

One question remains that the docket does not answer. The issuer of 76.95 % of the measured digital dollar is not on record in the public registry of the rule that defines who can issue it in the United States, and the docket says that and nothing more: it does not say why, nor if there was contact via another channel, nor what Tether thinks of the text. The company also has its own clock in this law, the January 2027 deadline for USDT, and an answer to that question can only come from the final rule or the company itself.

What remains measured is the distribution on the closing day. Of the fiat-backed digital dollar we measured on-chain, $49,176,661,203.67 has a letter in the Treasury docket and $182,550,760,688.22 does not. There are 161 letters and two issuer names: of the $237,225,706,837.51 base, 20.73 % is on the public record and 79.27 % is not, with Tether contributing 76.95 of those 79.27 percentage points.
