Securities Enforcement and Regulatory Update
SEC Issues “Innovation Exemption” for On-chain Trading of Tokenized U.S.-Listed Stocks
Effective as of September 17, 2026, the U.S. Securities and Exchange Commission (SEC or the Commission) issued a five-year, conditional exemptive order (the Innovation Exemption) that permits National Market System (NMS) stock (generally including any stock trading on national securities exchanges) to be tokenized and traded on-chain through automated market makers and liquidity pools (together, AMM Liquidity Pools).1 The Innovation Exemption, a highly anticipated component of SEC Chairman Paul S. Atkins’s Project Crypto agenda, exempts qualifying tokenized securities venues (TSVs) from the definition of “exchange” (the TSV Exemption) and qualifying liquidity providers, defined as Covered Firms, from the definition of “dealer” (the Covered Firm Exemption), in each case through September 17, 2031.2 A TSV therefore may operate outside the national securities exchange and alternative trading system (ATS) framework and outside Regulation NMS, subject to the conditions and caps described below.
The Innovation Exemption reaches every issuer of a stock traded on a national securities exchange, including U.S. public companies, not only firms active in digital asset markets. An NMS stock may be tokenized (1) by or on behalf of the issuer or (2) by an unaffiliated third party (collectively, Tokenized NMS Stock)3 and made available for trading on a TSV. Where a third party tokenizes an unrelated issuer’s security, the TSV must give the issuer written notice and 30 calendar days to object before trading begins. Institutional and retail investors alike may trade on a TSV, with self-custody,4 24/7 trading, fractional shares, and near-instantaneous settlement. The conditions the Commission has attached to the Innovation Exemption include ensuring identical economic and voting rights to the underlying shares, significant public disclosures and updates to the SEC, issuer notice and objection, public transaction data, coordinated trading halts, symbol and volume caps, and a prohibition on leverage. The Commission describes the relief as an interim measure pending rulemaking.
What This Means for Issuers
Two paths to tokenization. A public company (or other issuer of NMS stock) may tokenize its own shares (directly or through an agent) for trading on a TSV, or an unaffiliated third party may tokenize the issuer’s shares without the issuer’s involvement. The Innovation Exemption grants no relief to the entity doing the tokenizing, but provides relief to TSVs and liquidity providers.
Issuer Notice and the 30-day objection window. Before a TSV makes third-party-tokenized stock available for trading, it must send written notice to the issuer at the physical or email address of the issuer’s principal executive offices as listed on the cover page of its Exchange Act reports. Trading may not begin until at least 30 calendar days after the issuer receives the notice, and the issuer has until the 30th calendar day after receipt to object in writing to the TSV. A timely objection bars that TSV from making the third-party-tokenized stock available for trading, and the TSV must disclose the objection in its public filing (the TSV Public Filing). If the issuer does not object, trading in its tokenized stock may proceed. The Innovation Exemption does not contemplate a means of objecting after the 30 days have elapsed and a TSV is not required to provide notice where the issuer has sponsored the tokenization itself.
Shareholder rights and market safeguards. The TSV must verify that each Tokenized NMS Stock carries the same economic and voting rights as the underlying stock, and a third-party tokenization agent must pass through dividends and voting rights and distribute proxy materials to holders at no cost to the issuer. The Commission identifies the risk of maintaining the shareholder register given on-chain transfers, and potential price dislocation or other adverse effects on the price of the underlying stock from AMM pricing, as considerations an issuer may consider in deciding whether to object to the notice. On-chain trading in any one stock is capped at a small fraction of exchange volume, a TSV must halt trading whenever the primary listing exchange halts the associated stock, and TSV volume is not reported to the consolidated tape.5
What public companies and other NMS stock issuers may wish to do now:
- Confirm the notice channel is monitored. The 30-day clock runs from receipt at the principal executive office address, physical or email, shown on the cover page of the company’s Exchange Act reports. Issuers should confirm who receives mail and email at that address and that any TSV notice is escalated promptly to the legal department or corporate secretary.
- Form a view before a notice arrives. Because the objection operates against the notifying TSV, an issuer may receive notices from more than one venue and should be prepared to respond consistently. An objection is not private as the TSV must disclose it in its TSV Public Filing. Because the Innovation Exemption gives an issuer no right to information from a requesting venue beyond the TSV’s Public Filing, issuers may wish to prepare diligence questions in advance. Relevant considerations may include shareholder register maintenance, the potential for on-chain prices to diverge from exchange prices, investor relations, shareholder activism issues, and the company’s broader posture toward digital asset markets.
- Prepare for stockholder and market questions. Issuers whose stock begins trading on a TSV should expect questions from stockholders, analysts, and proxy advisors about voting, dividends, and record ownership and may wish to consider whether on-chain trading of their stock merits attention in their periodic disclosures.
- Assess the impact of 24/7 trading on compliance. Because a TSV may trade around the clock while the primary listing exchange does not, issuers should consider the implications for their insider trading, Regulation FD, and disclosure control policies and for their ability to manage the disclosure of material news, such as a significant M&A transaction.
- Consider briefing the board. Given the implications for investor relations, trading, and compliance, the Innovation Exemption and the company’s intended approach may be an appropriate item on which to advise the board.
- Consider commenting. The Commission has asked 10 questions, including whether the exemptions should be made permanent and whether the symbol and volume caps are correctly calibrated, and has not set a comment deadline.6
What This Means for Other Market Participants
- Investors and investment advisers. The Innovation Exemption opens a new source of liquidity in U.S.-listed stock to any investor that satisfies a TSV’s access standards, including sanctions and illicit-finance screening. Participants will typically hold Tokenized NMS Stock in their own blockchain wallets and will be able to trade around the clock and in fractional amounts. Advisers seeking this access for client accounts will need to work through how the custody rule under the Investment Advisers Act applies to self-custodied tokens, how to satisfy best execution on a venue whose prices are set by pool ratios rather than by reference to consolidated quotations, and how to value positions held in tokenized form. The Innovation Exemption does not address these questions.
- Broker-dealers, exchanges, and ATSs. The Innovation Exemption creates a path to operate an on-chain venue for NMS stock that does not require national securities exchange or ATS registration or compliance, including Regulation NMS and the fair access requirements of Rule 301(b)(5) of Regulation ATS, within the symbol and volume caps. An entity registered with the Commission for unrelated securities activity may operate a TSV, for example through an affiliate, but must keep the TSV’s operation separate from its registered activity. Registered broker-dealers may trade on a TSV as participants, but the relief does not extend to them. Broker-dealers remain subject to certain Regulation NMS rules, including the Vendor Display Rule (Rule 603), Trade Through Rule (Rule 611), Sub-Penny Rule (Rule 612), Consolidated Audit Trail reporting (Rule 613), and to FINRA Rule 6110 reporting for transactions effected otherwise than on an exchange.7 Comment question 7 asks whether relief for broker-dealer participants is warranted.
- Market makers and liquidity providers. The Commission states that liquidity provision alone does not constitute dealer activity and anticipates that absent other indicia of dealer activity, AMM liquidity providers typically would be traders rather than dealers. The Covered Firm Exemption extends to firms that also quote pricing to customers or commit capital under arrangements with a venue. However, a Covered Firm’s securities activities must be limited to trading Tokenized NMS Stock in an AMM Liquidity Pool operating under the TSV Exemption, so a firm with other securities business, including a registered broker-dealer, cannot itself qualify. A Covered Firm must trade solely for its own account, hold no customer assets, keep records of its financial capacity and its liquidity arrangements and compensation (including any fees, tokens, or incentives received for reaching volume thresholds), disclose on any public website that it is not a registered broker-dealer, and notify the Commission of its business model, risk controls, and arrangements. Neither the firm nor any affiliate may be subject to statutory disqualification.
- Prospective TSV operators. A TSV may operate for five years without registering as an exchange or ATS if it meets the conditions summarized under “Key Conditions” below. The principal undertaking is the TSV Public Filing, published at least 30 calendar days before operating, that covers 30 disclosure items spanning governance, access, ledger architecture, upgrade authority, fees, Maximal Extractable Value (MEV), systems safeguards, clearing arrangements, and risks and that must be kept current on a defined cadence.8 Operators will also need to reach their own conclusion on broker-dealer status — the TSV Exemption removes a TSV from the “exchange” definition but does not separately exempt it from Section 15(a) of the Exchange Act. The Commission characterizes TSV functions as exchange rather than brokerage activities and contemplates that a compliant TSV may operate without registration for the activities covered by the TSV Exemption, but the Innovation Exemption preserves “any other applicable laws,” and a TSV whose activities extend beyond venue functions (e.g., soliciting transactions, handling participant orders or assets, or routing) would need to evaluate broker status independently.
- Fund sponsors and stablecoin issuers. Tokenized money market funds and non security crypto assets, including payment stablecoins issued under the GENIUS Act, are permitted trading pairs on a TSV for Tokenized NMS Stock. The Innovation Exemption provides no relief under the Investment Company Act and flags Section 18, Section 22(d), and Rule 22c-1 as potential issues for tokenized funds.9
- Tokenization agents, custodians, and transfer agents. The relief runs to venues and liquidity providers only. An entity that tokenizes an NMS stock, whether on behalf of the issuer or as an unaffiliated third party, takes no benefit from the Innovation Exemption and remains subject to the analysis in the January 2026 SEC staff Statement on Tokenized Securities.10 Clearing agency and transfer agent status are not addressed.
Key Conditions and Limits
Symbol and volume caps. For Tier 1 stocks under the Limit Up–Limit Down Plan (LULD Plan) (principally S&P 500 and Russell 1000 constituents), a TSV may trade no more than 75 symbols, and its volume in any one stock may not exceed 0.25% of that stock’s prior-month average daily volume as reported to the consolidated tape. For Tier 2 stocks, the limits are 250 symbols and 2.5%.11 Both counts aggregate across affiliated TSVs. A first breach of a volume cap in a Tokenized NMS Stock requires only going-forward compliance; each subsequent breach requires a three-month pause in that Tokenized NMS Stock. Symbol caps carry no comparable grace and therefore a TSV that breaches a symbol cap can no longer rely on the Innovation Exemption.
TSV conditions. A TSV must be a U.S. person, and no person in its group may be subject to statutory disqualification. As a U.S. person, a TSV must comply with the economic and trade sanctions programs administered by the Office of Foreign Assets Control (OFAC), including the prohibition on transacting with persons on the SDN List and implementing a permissioned screening process for all TSV trading participants. Each TSV’s smart contracts must be auditable, public, and deployed on a public, permissionless ledger. A TSV may not conduct primary issuance, and all offers and sales of Tokenized NMS Stock must be registered or exempt. A TSV must publish U.S. dollar-denominated transaction data within 10 minutes of each trade; halt trading when the primary listing exchange halts the underlying stock; notify participants and the Commission of significant operational events; refrain from any lending, hypothecation, or extension of credit; disclaim SEC registration; and keep books and records in the United States, preserved for three years after the exemption ends, with consent to Commission examination. The TSV Public Filing must describe any policies addressing MEV or state that there are none, but the Commission does not prescribe MEV mitigation measures.
Regulation NMS. Because a TSV is exempt from the “exchange” definition, it is not a trading center or market center for Regulation NMS purposes, and Rules 605, 610, 611, 612, and 613 do not apply to it. The Commission’s stated rationale is that AMM pricing, which derives from the ratio of assets in a pool without reference to external quotations, is difficult to reconcile with the trade-through, quotation dissemination, and minimum pricing increment rules.12 Reliance on either exemption gives rise to no presumption that the TSV is an exchange or that the liquidity provider is a dealer.
Next Steps
The Commission describes the Innovation Exemption as an “interim, targeted measure,” and Chairman Atkins has stated that it “must be followed by durable rulemaking.”13 Sidley will continue to monitor developments and will issue further updates as the Commission acts on the comment file.

1Order Granting Temporary Conditional Exemptive Relief, Pursuant to Section 36(a)(1) of the Securities Exchange Act of 1934, from the Definition of “Exchange” in Section 3(a)(1) of the Exchange Act for the Use of Certain Distributed Ledger Trading Venues for Tokenized NMS Stocks and from the Definition of “Dealer” in Section 3(a)(5) of the Exchange Act for Certain Liquidity Providers for Tokenized NMS Stocks, and Request for Comment, Exchange Act Release No. 34-106402; File No. 4-927 (Sept. 17, 2026) (the Order). The Order was issued under Section 36(a)(1) of the Securities Exchange Act of 1934 (Exchange Act) and exempts TSVs from the definition of “exchange” in Section 3(a)(1) and Covered Firms from the definition of “dealer” in Section 3(a)(5). The Commission’s press release and fact sheet refer to the Order as the “Innovation Exemption,” and we use that term throughout; it does not appear in the text of the Order itself. See SEC Press Release 2026-90, SEC Issues “Innovation Exemption” to Facilitate the Trading of Tokenized NMS Stock and Request for Comment (Sept. 17, 2026), available at https://www.sec.gov/newsroom/press-releases/2026-90-sec-issues-innovation-exemption-facilitate-trading-tokenized-nms-stock-request-comment. The comment file is available at https://www.sec.gov/rules-regulations/2026/09/4-927.
2A TSV is “an organization, association, or group of persons that brings together buyers and sellers of Tokenized NMS Stock by: (1) providing one or more AMM Liquidity Pool(s) for permissioned participants to interact and agree to terms of a trade and (2) setting standards for persons to access trading on such AMM Liquidity Pool(s).” A venue “provides” an AMM Liquidity Pool by designating it as the means and location for trading or by exercising control over it (e.g., deploying the smart contract, setting pool parameters, determining fees, or having the ability to pause trading); merely “encoding a smart contract to whitelist an AMM Liquidity Pool” does not suffice. Where a TSV provides a functionality to enter, display, or agree to the terms of a trade, such as “a website, browser extension, or other software application,” that functionality is part of the TSV. A Covered Firm is a liquidity provider that supplies Tokenized NMS Stock to a pool using proprietary capital and may also engage in activities carrying indicia of dealing, such as quoting pricing to customers or entering into committed-capital arrangements.
3Tokenized NMS Stock does not include securities for which a third party issues a crypto asset representing its own security that provides synthetic exposure to an underlying security, such as a tokenized linked security or a tokenized security-based swap. It also does not include rights or warrants regarding the underlying NMS stock. Tokenized NMS Stock must trade in a pair with another Tokenized NMS Stock, a non security crypto asset (including GENIUS Act payment stablecoins), or a tokenized money market fund, and no primary issuance is permitted on a TSV.
4“Self-custody” means that a TSV participant holds its Tokenized NMS Stock directly in a blockchain wallet whose private keys the participant controls rather than through a broker-dealer, bank, or other intermediary that holds the securities on the participant’s behalf. The Commission identifies self-custody as one of the potential benefits of on-chain trading. The Innovation Exemption does not require participants to self-custody, and the custody implications for regulated intermediaries and investment advisers are discussed below.
5The Order does not require a TSV to report transactions to a securities information processor (SIP), and TSV volume is not included in the consolidated tape. A TSV must, however, publish U.S. dollar-denominated transaction data on its website within 10 minutes of each trade.
6The Commission’s 10 questions also ask whether registered broker-dealer participants require relief from Regulation NMS.
7Order at n.83, citing FINRA Rule 6110. Rule 603(c)(1) of Regulation NMS, 17 CFR 242.603(c)(1), prohibits a broker or dealer from displaying quotation or transaction information for an NMS stock, in a context where a trading or order-routing decision can be implemented, without providing an equivalent consolidated display, a question we identified in our April 15, 2026 Sidley Update, U.S. SEC Clears Path for Decentralized Crypto Asset Security Trading With Broker Registration Exception for User Interfaces, available at https://www.sidley.com/en/insights/newsupdates/2026/04/us-sec-clears-path-for-decentralized-crypto-asset-security-trading.
8The TSV Public Filing must be revised within five business days of commencing, ceasing, pausing, or resuming trading in any stock, at least 20 calendar days ahead of any material change, and quarterly for non material changes. Within one business day of publishing the TSV Public Filing, the TSV must give the Commission written notice that it intends to operate under the TSV Exemption. Volume and symbol compliance must be monitored on a basis aggregated across affiliates, and although a TSV may trade around the clock, the trade date for volume calculations begins when trades must be reported to the SIP.
9Order at n.22 (noting that tokenized investment companies may raise issues under Section 18, Section 22(d), and Rule 22c-1 of the Investment Company Act).

11Tier 1 under the LULD Plan comprises NMS stocks in the S&P 500 Index and the Russell 1000 Index and certain exchange-traded products; Tier 2 comprises all other NMS stocks other than rights and warrants. The Order explains that Tier 2 carries higher limits because percentage-of-volume thresholds “can more easily be exceeded for less liquid securities,” because Tier 2 contains more securities, and to “incentivize TSVs to make available for trading Tokenized NMS Stocks that are not only the most liquid securities.” The Order uses the LULD tiering only to categorize Tokenized NMS Stock and does not alter the LULD Plan. The Commission describes the caps as designed to limit risk to the broader market while participants “experiment with trading Tokenized NMS Stock on TSVs and as the Commission considers rulemaking.”
12The Order adds that the transparency that AMMs provide “may potentially obviate the need for certain regulations” and cites Section 11A(a)(2) of the Exchange Act, which directs the Commission to facilitate a national market system that “may include subsystems for particular types of securities with unique trading characteristics.” The Order also notes that on June 11, 2026, the Commission proposed to rescind the trade-through rule for NMS stocks, the provision regarding locking and crossing quotations, and certain defined terms. See Exchange Act Release No. 34-105655 (June 11, 2026), 91 FR 36656 (June 17, 2026); Order at n.33.
