SEC Tokenization Rule Gives Companies Just 30 Days to Object

By Grace Kim

Public companies now have exactly 30 calendar days to block third parties from tokenizing their shares — and if they miss the window, there is no process to reverse it. That is the core mechanic of an SEC Innovation Exemption, ordered September 17, 2026 and already in effect, that the US Chamber of Commerce is urging issuers to act on now.

The rule permits qualifying Tokenized Securities Venues, or TSVs, to facilitate trading of tokenized versions of publicly traded US stocks. The twist: the issuer doesn't have to consent. An unaffiliated third party may tokenize a company's shares and list them on a qualifying TSV, subject to specified conditions laid out in the order.

The only lever a company controls is a notice-and-objection process. Before trading begins, the TSV must send written notice to the issuer. From receipt, the company has 30 calendar days to file a written objection. A timely objection blocks the TSV from making those tokenized shares available for trading under the exemption.

Silence is the problem. If no objection arrives, the TSV can issue and trade the tokenized shares — and, as the Chamber puts it, there is currently no process for removing tokenized shares from the venue after the deadline passes. The Chamber calls a failure to respond "effectively irreversible."

What should public companies do right now?

The Chamber lays out four concrete steps, and the first is purely logistical:

• Fix mail routing. Notices go to the physical address listed for the company's principal executive offices. Route them straight to the legal or corporate secretary's office. Slow internal mail handling could burn the entire 30-day window.
• Build an evaluation process before a notice lands. Companies should decide internally how they will judge proposed third-party tokenizations — before the clock starts.
• Map the stakes. The Chamber flags shareholder-rights, investor-relations, operational, and market-structure implications as the four areas to analyze.
• Track every deadline and call counsel. Each notice starts a separate 30-day countdown, and the Chamber advises consulting appropriate counsel without delay on whether to object.

One company could face several overlapping deadlines. Multiple TSVs may independently send notices, and each triggers its own 30-day objection period.

How long does the exemption run?

Through September 17, 2031, unless the SEC modifies it. Because the order took effect on day one — September 17, 2026 — the Chamber warns that the clock may already be running for some issuers. A notice could be sitting in a mailroom today.

The exemption is part of the SEC's innovation framework; the agency's materials are published at sec.gov under file 4-927.

What's next?

The US Chamber of Commerce says it is reviewing the implications for public companies and the broader capital markets and "will continue to engage on this issue." For issuers, the practical deadline isn't 2031 — it's whatever date the first TSV notice hits the front desk.
