SEC proposal paves way for tokenized stocks

TLDR

The SEC has floated a rule change that could remove a key legal barrier to trading tokenized U.S. stocks, including on DeFi platforms.

1. The proposal would rescind Regulation NMS Rules 611 and 610(e), with a 60 day comment period and potential finalization around early 2027.
2. Removing these rules would let tokenized stocks fit better into a broker level best execution regime, solving a problem that made AMM based tokenized equities effectively non compliant.
3. Tokenized stocks are not green lit yet, so the real signals will be SEC comments, pilot exemptions, and how fast exchanges and big banks move on tokenization.

Deep Dive

1. What The SEC Actually Proposed

The SEC has proposed rescinding two core pieces of U.S. equity market structure, Regulation NMS Rules 611 and 610(e), which currently enforce best price execution across exchanges and restrict locked or crossed quotes in National Market System stocks. The proposal starts a 60 day public comment period after publication in the Federal Register and is framed as a way to simplify market structure and cut costs while still supporting innovation in equity trading. According to coverage, officials and analysts expect final rulemaking around Q1 2027, with the possibility of earlier exemptions for limited pilots in tokenization and other experiments.

2. Why This Matters For Tokenized Stocks

Rule 611 requires trades to respect the national best bid and offer across venues, and Rule 610(e) limits locked or crossed quotes. Automated market makers on chains execute against a pool price and cannot check or pause for better quotes on Nasdaq or other exchanges, which is why Galaxys Alex Thorn calls these rules one of the biggest structural barriers to tokenized U.S. equities in DeFi. The SEC is expected to lean more on a principles based best execution standard at the broker level, which is easier to align with AMM behavior and could make compliant tokenized NMS stocks possible if other conditions are met.

3. Remaining Hurdles And What To Watch

Even if 611 and 610(e) disappear, tokenized stocks still must navigate exchange or ATS registration, clearing and settlement rules, and investor rights so that digital shares match traditional ones. The SEC is also exploring an innovation exemption that could explicitly cover tokenized versions of existing public equities, and it has already backed pilots like Nasdaqs tokenized stock trading program and NYSEs partnership with Securitize for tokenized shares and ETFs. In parallel, banks such as Citi and platforms like Binance and Backpack are rolling out tokenized private shares and stock products, testing the plumbing ahead of full regulatory clarity.

Conclusion

The SECs move to rethink Rules 611 and 610(e) removes a major structural mismatch between traditional equity rules and how AMM based tokenized stocks work. If the proposal survives the comment process and is paired with targeted exemptions and pilot programs, it could legitimize a much larger market for tokenized equities. For crypto users, the key signals will be concrete pilots on major venues and how regulators handle registration, settlement, and investor protections for these onchain stock products.
