What Hester Peirce Means by “Not Synthetics”: Why Every Tokenized Securities Investor Needs to Know
And the odd intersection of RWA, AI, and The SEC that brought us here
If you think you invested in Anthropic common stock when you bought tokenized shares from an SPV, you are probably going to get rekt.
And it doesn’t end with Anthropic.
That’s the short version of a much longer story, and the longer version starts with a tweet.
On May 21, 2026, SEC Commissioner Hester Peirce posted this on X: “I appreciate the interest in, but not the hyperbole about, the contemplated innovation exemption for the onchain trading of tokenized NMS stock. Keep in mind: I’ve always expected that it’d be limited in scope and would facilitate trading only of digital representations of the same underlying equity security that an investor could purchase in the secondary market today, not synthetics.”
The comments were full of confusion about the last two words. What is a “synthetic”? Why does it matter? How do you know if what you’re buying is one?
This piece is an attempt to answer those questions precisely, because the answer turns out to have a lot of money riding on it.
I should say upfront that I’m not a neutral observer. Vertalo issued the first Reg D tokenized equity RWA in March 2018 and built what became one of the first purpose-built digital transfer agent platforms, designed from the ground up to record security ownership on distributed ledger technology and to protect the rights and interests of both issuers and investors. We started in private markets, which is exactly the market Anthropic operates in, and the problems we were solving then are the same ones showing up in every synthetic tokenization structure today. Whether the issuer is a pre-IPO AI company, a SpaceX-scale private unicorn, or a currently-trading NMS listed stock, the recordkeeping architecture is the same and so is the failure mode. I provide services to issuers of securities. That’s my perspective, and you should factor it in.
A “synthetic” in Peirce’s context is any tokenized instrument that gives you economic exposure to a security without giving you actual ownership of it. What you hold instead is a claim against an intermediary: a fund, an SPV, a platform, a broker. The intermediary may hold the underlying security, or may have hedged its exposure to it, or may have done something else entirely. You won’t always know. What you do know is that your name is not on the issuer’s books, and the issuer has never acknowledged you as a shareholder.
The legal framework for this distinction is Article 8 of the Uniform Commercial Code, which has governed securities transfers in the United States since 1994. Under UCC §8-102, the law separates two fundamentally different ways of holding a security. A “direct holder” is someone whose ownership is recorded on the issuer’s books, no intermediary required. Everyone else is an “entitlement holder”: a person identified in the records of a securities intermediary as having a security entitlement against the intermediary. Not against the shares. Against the firm that’s holding them for you.
Most investors in traditional brokerage accounts are entitlement holders and don’t know it. Your broker holds a claim against its clearing firm, the clearing firm holds a claim against DTCC, and DTCC’s nominee entity, Cede & Co., is the legal owner of record for virtually every publicly traded U.S. share. It’s a four-layer chain of entitlements, and it mostly works because every participant in the chain is regulated, reconciled, and backstopped. But the architecture has a known failure mode: when the authority to create entitlements lives in the netting layer rather than the issuer’s own records, the total count of entitlements can exceed the total count of authorized shares. That’s exactly what happened during the GameStop episode in 2021, when short sellers had sold roughly 40% more shares than existed, because the entitlement system permits positions to accumulate before anyone is required to reconcile them against the issuer’s authorized count.
Synthetic tokenized securities recreate this same architecture on a new rail. An SPV acquires, or claims to acquire, a position in a private company. It then sells tokens representing economic interests in that position. Token buyers hold entitlements against the SPV. The SPV holds entitlements against its broker. The issuer’s cap table reflects none of this and was never consulted about any of it.
Anthropic just showed everyone how fast that structure fails.
On May 12, 2026, Anthropic published the following: “We do not permit special purpose vehicles to acquire Anthropic stock and any transfer of shares to an SPV are void under our transfer restrictions. Any sale or transfer of Anthropic stock, or any interest in Anthropic stock, offered by these firms is void and will not be recognized on our books and records.”
“Books and records.” “Void.” “Will not be recognized.” Tokens representing SPV claims on Anthropic dropped roughly 40% when that statement landed, not because the company’s value changed but because the market finally priced in what those investors had actually owned: a position at the bottom of an entitlement pyramid that the issuer just declared invalid. Platforms like Forge Global, Hiive, and Open Door Partners had built products on the premise that SPV exposure to Anthropic was the next best thing to owning Anthropic stock. Anthropic’s statement made clear that from the issuer’s perspective, those positions never existed.
That’s what Peirce means by “not synthetics.” A token representing your entitlement against an intermediary is not, in the eyes of the issuer or the law, the same thing as owning the security it references.
Robinhood’s tokenized stock products are a retail version of the same structure. OpenAI, SpaceX, and other companies whose equity Robinhood has offered as “tokenized” didn’t authorize any of it. OpenAI’s response was direct: “These ‘OpenAI tokens’ are not OpenAI equity. We did not partner with Robinhood, were not involved in this, and do not endorse it.” Retail investors buying these products are holding synthetic exposures, not equity. They are entitlement holders against Robinhood’s offshore entity, not shareholders of the underlying companies. Peirce’s innovation exemption, if it materializes, would explicitly exclude these products, and her May 21 tweet was a response to the enthusiasm around that exemption, enthusiasm that apparently assumed the exemption would bless a much wider range of instruments than she ever intended.
The structural fix to all of this is a transfer-agent-issued tokenized equity primitive, and I can say with some authority that it’s already technically possible, because Vertalo built it.
When an authorized transfer agent mints a token representing an issued share under the issuer’s explicit direction, that token IS the entry on the master securityholder file. There’s no securities intermediary in the chain. The token holder is a direct holder under the UCC, not an entitlement holder. Total token supply equals authorized, issued share count, enforced in code, auditable by the issuer and regulator in real time, and structurally incapable of exceeding the authorized cap. You cannot sell a share you don’t have when “having a share” means controlling a token on an immutable ledger reconciled against the issuer’s authorized count on every block.
This is what Peirce’s exemption is designed to facilitate, and it’s the architecture that makes the “not synthetics” boundary meaningful rather than rhetorical. A TA-minted NMS stock token is a digital representation of the same underlying equity security an investor could purchase in the secondary market today, because it IS that security. The transfer agent minted it. The issuer authorized it. The investor is on the issuer’s books.
That’s the opposite of a synthetic, and that distinction matters whether you’re an investor trying to avoid getting rekt or a regulator trying to write a rule that holds.
What Anthropic enforced defensively after the fact, what Peirce has been saying consistently for close to a year, and what the UCC has said since 1994 all point to the same conclusion: an entitlement against an intermediary is not ownership of a security, and any token that represents only the former will eventually be priced like it. The SEC’s rulemaking around onchain NMS equity is the opportunity to close that gap at the infrastructure level. The comment period is the industry’s chance to say so clearly enough that it shapes what actually gets built.
Investors should probably say something too.
