Citadel Securities and major crypto organizations are fighting over how the Securities and Exchange Commission should regulate decentralized finance platforms that handle tokenized stocks. The dispute centers on whether DeFi protocols should face the same rules as traditional exchanges.

Citadel Securities sent a 13-page letter to the SEC earlier this month. The investment firm argued that DeFi platforms offering tokenized US equities should register as exchanges or broker-dealers under securities laws.

The company said giving DeFi platforms “broad exemptive relief” would create problems. Citadel warned this approach would establish two separate regulatory systems for trading the same security.

A coalition of crypto groups responded on Friday with their own letter to the SEC. The DeFi Education Fund, Andreessen Horowitz, the Uniswap Foundation, The Digital Chamber, Orca Creative, and lawyer J.W. Verret signed the response.

The crypto coalition called Citadel’s arguments “baseless” and accused the firm of making “several factual mischaracterizations and misleading statements.” They said they share Citadel’s goals of protecting investors and maintaining market integrity.

However, the groups disagreed that DeFi platforms must register as traditional SEC intermediaries. They argued that thoughtfully designed onchain markets can meet these goals through different methods.

DeFi Groups Challenge Citadel’s Arguments

The crypto coalition said Citadel’s proposal would be “impracticable given their functions.” They warned the rules could affect a wide range of onchain activities not typically considered exchange services.

The groups took issue with Citadel calling autonomous software an intermediary. They said software cannot be a middleman because it is not a person capable of exercising independent discretion or judgment.

“DeFi technology is a new innovation that was designed to address market risks and resiliency in a different way than traditional financial systems do,” the coalition wrote. They claimed DeFi protects investors in ways traditional finance cannot.

Citadel Securities defended its position in a statement. A spokesperson said the firm “strongly supports tokenization and other innovations that can reinforce America’s leadership in digital finance.”

The company added that innovation should not require “sacrificing the rigorous investor protections that have made U.S. equity markets the global gold standard.” Citadel argued that DeFi platforms without regulation lack protections like venue transparency, market surveillance, and volatility controls.

SEC Seeks Industry Input on Tokenization Rules

The exchange of letters comes as the SEC collects feedback on how to regulate tokenized stocks. SEC chair Paul Atkins recently said the US financial system could embrace tokenization in a couple of years.

The new SEC leadership under President Donald Trump has been looking for ways to give the crypto industry more regulatory flexibility. White House crypto adviser Patrick Witt posted on social media that his office supports protecting software developers and DeFi.

DeFi Education Fund spokeswoman Jennifer Rosenthal suggested Citadel has business reasons for its stance. “It is convenient for Citadel to question the existence of a technology that threatens its business and market share,” Rosenthal said.

Blockchain Association CEO Summer Mersinger previously criticized Citadel’s letter as an “overbroad and unworkable approach.” Tokenization has grown rapidly this year, but NYDIG warned on Friday that assets moving onchain won’t immediately benefit crypto markets until regulations allow deeper integration with DeFi.
