Citadel Securities Turns Against DeFi While Pouring $500 Million into Ripple

Citadel Securities has taken a dual stance in crypto, publicly opposing regulatory exemptions for decentralized finance (DeFi) while co-leading a $500 million investment in Ripple.

The move highlights a growing divide between institutional support for compliant blockchain infrastructure and skepticism toward fully decentralized protocols.

Citadel’s Push Against DeFi Loopholes

Citadel Securities submitted a formal letter to the SEC on December 2, 2025. In the letter, the capital markets firm opposes carve-outs for DeFi platforms trading tokenized US equities.

The firm argued that decentralized platforms must adhere to existing investor protections. The letter raises concerns about transparency, anti-money laundering (AML) and know-your-customer (KYC) compliance, market controls, and custody standards.

“Exempting DeFi from oversight could endanger investors and the broader market,” the letter warned, urging consistent regulation across all trading venues, centralized or blockchain-based.

The stance drew criticism from crypto advocates. The Blockchain Association warned that applying traditional rules to open-source protocols could stifle innovation.

This debate mirrors historical SEC conflicts, such as those between former Chairman Gary Gensler, who favored strict enforcement, and Commissioner Hester Peirce, who often dissented, advocating for regulatory flexibility.

Despite its public opposition to DeFi exemptions, Citadel co-led a $500 million funding round for Ripple.

The investment values Ripple at $40 billion, signaling confidence in its regulated, compliance-focused infrastructure. Other participants included Pantera Capital, Galaxy Digital, Brevan Howard, and Marshall Wace.

Ripple has expanded aggressively in the institutional market. It acquired six firms in two years, including Hidden Road (rebranded as Ripple Prime) for $1.25 billion. Hidden Road now serves 300 institutions and processes $3 trillion in annual transactions.

Additional acquisitions, like GTreasury ($1 billion) and Rail ($200 million), strengthened Ripple’s custody, settlement, and treasury services.

The firm’s RLUSD stablecoin has surpassed $1 billion in market cap, and a recent 25% share buyback reflects its financial discipline.

Ripple now holds 75 global licenses and has processed $95 billion in payments, positioning itself as a bridge between traditional finance and blockchain.

Market Reaction and Implications

Despite the institutional backing, XRP fell almost 10% to $2.17 following the investment announcement, reflecting investor uncertainty about its immediate utility.

The contrast between Citadel’s public regulatory advocacy and private market bets highlights a broader trend. Institutions prefer blockchain projects that operate within regulated frameworks rather than fully permissionless systems.

As regulations improve, capital is increasingly flowing toward compliant blockchain solutions, reinforcing investor protections while maintaining innovation.

Citadel’s moves signal that regulatory clarity is now a prerequisite for large-scale institutional adoption, even if it diverges from the ethos of DeFi.
