Citadel Sparks Outrage After Urging SEC to Strictly Regulate DeFi Tokenized Stocks
Market maker Citadel Securities has triggered a wave of backlash across the crypto industry after urging the U.S. Securities and Exchange Commission (SEC) to impose tighter regulations on DeFi platforms offering tokenized equities.

In a letter to the SEC on Tuesday, Citadel argued that DeFi developers, smart contract coders, and self-custody wallet providers should not receive “broad exemptive relief” when enabling the trading of tokenized U.S. stocks.
According to Citadel, if a decentralized platform facilitates the buying and selling of tokenized equities, it likely falls under the definition of an exchange or broker-dealer — and therefore must comply with existing securities laws.
“Granting broad exemptive relief to facilitate the trading of a tokenized share via DeFi protocols would create two separate regulatory regimes for the same security,” the firm wrote.
“This would be the opposite of the technology-neutral approach of the Exchange Act.”
The letter was submitted as part of the SEC’s open request for public feedback on how tokenized stocks should be regulated — and it immediately drew criticism from crypto leaders, industry advocates, and DeFi developers.
Crypto Community Pushes Back: “Citadel Fears Competition”
Lawyer and Blockchain Association board member Jake Chervinsky mocked Citadel’s stance, saying it was entirely predictable:
“Whoever thought Citadel would support innovation that removes predatory intermediaries from the financial system?”
“Oh right — literally everyone in crypto knew they wouldn’t.”
Uniswap founder Hayden Adams echoed the sentiment, arguing that Citadel is threatened by open, transparent systems:
“Makes sense that the king of shady TradFi market makers doesn’t like open-source, peer-to-peer technology that lowers the barrier to liquidity creation.”
Summer Mersinger, CEO of the Blockchain Association, delivered a much stronger warning. She emphasized that regulating software developers as though they were financial intermediaries would:
- undermine U.S. competitiveness
- push innovation offshore
- fail to improve investor protection
“We urge the SEC to reject this unworkable approach and instead focus on actual intermediaries who stand between users and their assets.”
Citadel’s Broader Position: 'No Regulatory Loopholes'
This is not Citadel’s first time pressuring regulators.
In July, Citadel sent another letter to the SEC’s Crypto Task Force, arguing that tokenized securities must succeed on technological merit, not by taking advantage of regulatory gaps.
The firm said the SEC should ensure all market participants — whether centralized or decentralized — remain within a uniform regulatory framework.
TradFi Groups Join Citadel: SIFMA Also Opposes Any DeFi Exemptions
Citadel isn’t alone. The Securities Industry and Financial Markets Association (SIFMA) — one of Wall Street’s largest trade groups — issued a similar statement on Wednesday.
SIFMA said it supports blockchain innovation but insisted that tokenized securities must be subject to the same investor protections that apply to traditional securities.
The group cited recent market volatility, including the October crypto flash crash, as evidence that strong regulatory frameworks remain essential:
“These disruptions remind us why securities regulations were created in the first place — to protect investors and preserve market quality.”
SIFMA had already taken the same position in July, rejecting SEC exemptive relief for DeFi platforms that issue tokenized assets.
In November, the World Federation of Exchanges — representing major global stock exchanges — also urged the SEC to abandon its idea of granting an “innovation exemption” to tokenized-asset providers.
A Deepening Divide Between DeFi and Wall Street
Citadel’s comments reignited a broader debate:
- Should decentralized protocols be treated the same as centralized brokers?
- Should open-source developers be regulated like Wall Street intermediaries?
- Does tokenizing stocks require new laws — or just enforcement of old ones?
To many in crypto, Citadel’s position reflects fear of competition:
- DeFi reduces middlemen.
- Tokenization simplifies global access to assets.
- Smart contracts can replicate many functions of market makers — without the fees.
To Wall Street, however, DeFi may look like an unregulated threat to investor safety and market stability.
Conclusion: The Battle Over Tokenized Stocks Is Just Beginning
Citadel’s letter highlights a fundamental tension at the heart of modern finance:
Should innovation reshape markets, or should markets reshape innovation?
The SEC’s eventual decision will influence:
- whether DeFi can play a major role in tokenized stock markets
- whether developers can build openly without being treated as financial institutions
- whether the U.S. will lead or fall behind in blockchain innovation
One thing is certain:
The fight between legacy financial giants and decentralized systems is far from over — and tokenized equities may be the next major battleground.
