The chairman of the U.S. Securities and Exchange Commission just said something that could reshape the global financial system: “I would like to see the stock market run on blockchain.”
This is not crypto-industry hype. The person who said it is Paul Atkins, Chairman of the U.S. Securities and Exchange Commission (SEC). In a live interview with CNBC, he made it clear that the entire financial system is moving toward the crypto era.
Put simply: the gatekeeper of the worlds largest capital market is actively inviting blockchain in, rather than keeping it outside the door.
What Does “Putting Stocks On-Chain” Actually Mean？
The first thing many people think of is: “Turn Apple stock into a token.”
But the reality is much more interesting.
When you buy a U.S. stock, this is roughly what happens behind the scenes: your money starts at a bank, moves through a broker, is matched on an exchange, confirmed by a clearinghouse, and recorded by a custodian. Only then do you effectively “own” the stock. The entire process currently operates on a T+1 settlement cycle—sell today, and the transaction settles the next business day.
The logic of on-chain stocks is much simpler:
Stock = TokenBroker = WalletClearing = Smart ContractDollar = Stablecoin
The SEC chairman has said he wants to “bring the U.S. capital markets into the digital age and facilitate the on-chain trading of tokenized securities.”
That does not mean taking stocks outside the regulatory system. Instead, it means allowing legally compliant securities to operate on a different underlying infrastructure—from the traditional broker → exchange → clearinghouse chain to real-time settlement on blockchain networks.
This Is No Longer Just Talk—The Rules Are Already Here
One of the most overlooked aspects of this development is that it is no longer merely being discussed.
On September 17, 2026, the SEC formally issued a five-year temporary exemption known as the “Innovation Exemption.” It allows qualifying tokenized securities trading platforms to conduct on-chain trading of U.S. national market system stocks, using automated market makers and liquidity pools to match buyers and sellers.
There is one particularly important feature of the exemption: tokenized stocks must give holders the same rights and privileges as traditional shares, including dividend and voting rights.
In addition, the smart contracts underlying the tokens must be publicly auditable and deployed on permissionless public blockchains. If the underlying stock is halted on a primary exchange, the tokenized version must also stop trading.
In simple terms, the SEC wants the efficiency of blockchain without giving up the legal protections of traditional securities.
This is a classic American regulatory-innovation approach: give the technology a five-year testing window, see whether it works, and then potentially turn what works into permanent rules.
Wall Street Is Moving Faster Than Regulators
If you think the SEC is already moving aggressively, look at what Wall Street is doing.
The New York Stock Exchange (NYSE) announced in January 2026 that it was developing a blockchain-based platform for tokenized securities, supporting 24-hour trading, fractional orders, and stablecoin settlement.
In September, the NYSE signed a memorandum of understanding with crypto platform Blockchain.com, which has more than 44 million users. Blockchain.com will serve as a distribution channel for NYSE tokenized stocks and ETFs.
BlackRock moved even earlier.
Its BUIDL fund—a money-market-style fund operating on blockchain—saw on-chain transfers reach $441 million in June, with daily redemption arrangements reaching the $1 billion level. The fund has also been accepted as collateral.
In August, BlackRock brought 12 of its European money market funds, representing a combined $311 billion in assets, onto Ethereum in tokenized form through JPMorgans Kinexys platform.
JPMorgans Kinexys network processes more than $7 billion in transactions every day and has processed more than $4 trillion cumulatively since launch.
Citigroup estimates that the tokenized securities market could reach approximately $5.5 trillion by 2030.
But perhaps the most important signal is coming from DTCC, the core infrastructure behind securities clearing and settlement in the United States. It clears and settles roughly $15 trillion worth of securities transactions every day.
In July, DTCC completed its first real-time transaction involving tokenized securities and plans to officially launch the service in October.
When the clearinghouse itself starts using blockchain, you know this is no longer just an experiment.
Why Could This Be 100 Times Bigger Than the Bitcoin ETF？
When spot Bitcoin ETFs were approved in 2024, traditional capital gained a regulated channel for gaining Bitcoin exposure.
That was essentially “bringing crypto into traditional finance.”
What is happening now reverses the direction:
Traditional finance is moving onto blockchain.
Consider the numbers.
Global equity market capitalization is roughly $120 trillion, while the U.S. stock market accounts for approximately $75 trillion.
By comparison, the global on-chain RWA (real-world asset) market is around $332 billion, according to a recent report from Pantera Capital, covering 671 assets.
$332 billion vs. $75 trillion.
If just 1% of U.S. equities moved on-chain, that would represent $750 billion of new assets entering the on-chain ecosystem.
Deutsche Bank has offered an even more aggressive projection, estimating that the tokenized RWA market could reach $4 trillion by 2035.
A joint report from Boston Consulting Group and ADDX estimates the potential market for tokenized illiquid assets at as much as $16.1 trillion.
These figures refer to different segments of the market, but they point in the same direction:
Tokenization is moving from a “crypto concept” to a Wall Street business.
As BlackRock CEO Larry Fink has put it, tokenization is “the next generation of markets.”
But Don't Rush to Go All In
By this point, you may be thinking: So what should I do now？
First, stay calm.
There are several real-world issues that need to be taken seriously.
First, This Is Still a Five-Year Experiment
The exemption runs through September 2031 and comes with limits on eligible securities and trading volumes.
The SEC can also modify or revoke it at any time.
This is not a blanket deregulation. It is a regulatory sandbox.
Second, Fragmentation Is a Real Risk
The CEO of Fairmint has warned that tokenized stocks could recreate the kind of “paperwork crisis” Wall Street experienced in the 1960s.
Back then, trading volumes surged while the clearing system struggled to keep up, leaving large numbers of transactions unresolved.
Today, if exchanges, special-purpose vehicles, tokenization providers, and other participants each maintain separate ledgers and systems, ownership records could become fragmented again.
Investors could potentially face uncertainty over voting rights, dividend rights, and claims on underlying assets.
Third, Traditional Interests Will Not Give Way Easily
DTCC, brokers, custodians, and other intermediaries all have enormous commercial interests tied to the existing financial infrastructure.
If tokenization truly takes off, it could significantly compress some of these intermediary layers.
When some participants benefit, others may lose revenue.
As a result, the pace of reform could be much slower than market expectations.
Fourth, Issuers' Attitudes Will Be a Critical Variable
Whether a stock ultimately moves on-chain depends, in the end, on authorization from the listed company.
If Apple or Tesla does not want its shares tokenized, on-chain trading may be limited to synthetic representations rather than the actual underlying stock.
What Is the Real Story？
For more than a decade, the crypto industry has told one big story:
“We are going to use blockchain to disrupt traditional finance.”
Now the story is changing.
The SEC chairman says he wants stocks to run on blockchain.
The NYSE is building a tokenized securities platform.
BlackRock has moved $311 billion of money-market fund assets onto blockchain infrastructure.
DTCC is beginning to use blockchain for securities settlement.
This is no longer simply crypto challenging traditional finance.
It is traditional finance actively embracing blockchain.
Bitcoin may have solved the problem of “digital gold.”
Stablecoins may be solving the problem of “digital dollars.”
And the broader tokenization of stocks, bonds, funds, and ETFs could be solving the problem of “digital Wall Street.”
This may not necessarily become the next crypto bull-market narrative.
But it could represent the real starting point of the global financial system's transition from the internet era to the on-chain era.
When the world's largest stock exchanges begin asking whether their core infrastructure should run on blockchain, the answer to that question may ultimately matter more than any individual bull market.
