Two Regulators, Zero New Statutes: How Tokenized Stocks Got Their Rulebook Anyway

The rulebook for tokenized equities is being drafted right now, and Congress isn't holding the pen.

Michael Selig, the CFTC chairman, made that plain this week. His argument is that tokenization changes how markets clear, settle, and list. He's not wrong. The SEC has been walking the same path from the other side of the street, opening the door to onchain versions of publicly traded stocks while the CLARITY Act sits parked in the Senate. Two agencies. One direction. No new statute needed.

Developers should note the breaking change in the return type. The question is no longer whether US rails will carry tokenized equity. It's which smart contract holds the shareholder registry when they do.

The evidence stack

Start with the paperwork. Nasdaq filed in September 2025 to let listed companies trade tokenized versions of their own shares through the same order book and the same ticker. The Depository Trust and Clearing Company got no-action relief to pilot tokenized settlement on real securities. Those aren't pilots in a sandbox with pretend money. They touch the actual clearing stack.

Now the money. Tokenized US Treasury products passed $7 billion in total value during 2025, with BlackRock's BUIDL fund and a handful of competitors holding most of it. That's up from roughly $100 million at the start of 2024. The growth curve isn't a narrative device. It's a balance sheet.

Then there's the personnel angle. The SEC under Paul Atkins stood up Project Crypto and an innovation exemption framework aimed squarely at onchain securities. Hester Peirce's crypto task force has been running public input sessions for months. Selig, for his part, has been saying the quiet part into a microphone. The CFTC, in his framing, should be the primary regulator for spot digital commodity markets. That's a jurisdictional claim, and he's making it in public rather than in a comment letter.

The specification is as follows. When two agencies with overlapping mandates both decide a technology is inevitable, they race to define it first. Whoever writes the definitions writes the compliance cost. Whoever writes the compliance cost picks the winners.

Who actually wins here

Not the token issuers. That's the part most people get backwards.

The winners are the firms that already hold broker-dealer licenses, transfer agent registrations, and custody charters. Tokenized equity doesn't remove the need for a transfer agent. It changes what the transfer agent's software looks like. The registry moves from a database behind a login to a contract with a public ABI, and the reconciliation work that used to take two days per corporate action collapses into a single transaction.

That's the real prize. Not the token. The register.

So who loses? Crypto-native exchanges that assumed tokenized stocks would route around traditional market structure. They won't. Every serious proposal so far has the tokenized share sitting inside the same National Market System plumbing as the regular one. Same best-execution rules. Same trade reporting. If you built a venue on the assumption that tokenized equities would get a lighter touch than the shares they represent, you built on sand.

The counterpoint, and it's a real one

Here's where the bears make a fair argument. Agency rulemaking is fragile in a way that statutes aren't.

Guidance letters get withdrawn. No-action relief gets rescinded. Innovation exemptions have expiry dates baked in because that's the whole point of calling them exemptions. The CLARITY Act, for all its problems, would put definitions for digital commodities and ancillary assets into law. That's durable. A staff bulletin isn't.

There's also the litigation overhang. Nothing stops a future commission from re-reading the same statutory text a different way. The Howey framework didn't change between 2021 and 2025, but the conclusions drawn from it changed dramatically. That should tell you something uncomfortable about relying on discretion.

And there's a practical limit nobody wants to say out loud. Tokenizing a share doesn't make the issuer's cap table simpler. It makes it harder to audit unless the token contract and the transfer agent's books stay in lockstep, block by block. Get that wrong and you've created a reconciliation nightmare with regulatory exposure on both sides. Forced transfers, corporate actions, fractional voting, proxy plumbing. None of that's solved by a mint function.

Can a smart contract model a shareholder of record under state corporate law? That's the question nobody in Washington has answered yet, and it's the one that matters most.

The verdict

Tokenized US equities will be live at meaningful scale on regulated rails before Congress passes a market structure bill. I'll take that position without hedging. The agencies have too much momentum, the technology works, and the commercial incentive for issuers is straightforward: programmable shareholder registries mean cheaper corporate actions and faster settlement, and settlement speed is money.

But here's my second call, and it cuts the other way. The CLARITY Act stalling is bad for the industry even though it feels like a reprieve. Every month without statutory definitions is a month where the entire legal basis for tokenized securities rests on the judgment of five appointed commissioners. That's a single point of failure, and it's a worse architecture than any of the contracts being written on top of it.

Backward compatibility is maintained except where noted below. And what's noted below, in practice, is custody. The tokenized equity market will inherit the custody rules of the traditional market, which means the firms already holding qualified custodian status control the onramp. If you're building today, build for a world where a broker-dealer sits between your contract and the end user. That's not a prediction. It's the shape of every filing the SEC has accepted so far.

The execution client doesn't care whether the asset is a bearer token or a book-entry claim. Regulators do. And right now, the regulators are the ones writing the spec.
