Securitize Review 2026: The Infrastructure Behind BlackRock's BUIDL Fund

# Securitize Review 2026: The Infrastructure Behind BlackRock's BUIDL Fund

When BlackRock — the world's largest asset manager with $11+ trillion in AUM — decided to tokenize a money market fund, they didn't build their own infrastructure. They chose Securitize.

That single decision tells you most of what you need to know about Securitize's position in the tokenization ecosystem. Named CoinDesk's Most Influential in 2025, CEO Carlos Domingo has built something rare in crypto: a full-stack, fully regulated tokenization platform that institutional finance actually trusts.

What Securitize Does

Securitize is a regulated financial infrastructure company that enables the issuance, management, and trading of tokenized securities. Unlike DeFi protocols that operate outside of traditional regulatory frameworks, Securitize holds:

• SEC-registered Transfer Agent — the entity that maintains the official record of security ownership
• SEC-registered Broker-Dealer (Securitize Markets) — can facilitate trading of tokenized securities
• SEC-registered Alternative Trading System (ATS) — a secondary marketplace for tokenized securities
• SEC-registered Investment Adviser — can provide investment advisory services
• FINRA member — subject to self-regulatory oversight

This regulatory stack is nearly impossible to replicate. It took years and significant capital to build, which is why BlackRock, Hamilton Lane, KKR, and other institutional giants chose Securitize rather than building in-house.

The BlackRock BUIDL Fund

The BUIDL (BlackRock USD Institutional Digital Liquidity) fund is Securitize's flagship showcase. Launched in March 2024, it has grown to approximately $2.8 billion in AUM, making it the largest tokenized fund in existence.

BUIDL matters for crypto lending because it demonstrates that tokenized money market funds can operate at institutional scale with full regulatory compliance. The fund's tokens can be used as collateral in DeFi protocols — Aave and MakerDAO/Sky have both integrated or explored BUIDL as collateral.

Scale and Traction

Securitize's numbers reflect the institutional tokenization wave:

The decision to go public via SPAC merger with Cantor Fitzgerald (expected ticker: SECZ) signals confidence that institutional demand for tokenization infrastructure is durable, not cyclical.

How Securitize Compares

What This Means for Crypto Lending

Collateral expansion: As Securitize tokenizes more institutional-grade assets (private equity, credit funds, real estate), these become potential collateral for crypto lending protocols. A tokenized Hamilton Lane private equity fund share could collateralize a stablecoin loan — something impossible in traditional finance.

Yield diversification: Platforms integrating BUIDL-style products offer lenders access to Treasury-grade yields through familiar DeFi interfaces. This diversifies the yield sources available to crypto lenders beyond borrower-paid interest.

Regulatory precedent: Securitize's regulatory stack proves that tokenization can work within existing securities law. This is the SEC's January 2026 guidance in action — the plumbing changes, the rules don't.

Risks and Considerations

• Concentration risk: Securitize's dominance in institutional tokenization infrastructure means the space is heavily dependent on one company
• SPAC risk: SPAC mergers carry execution risk; valuation may not hold post-merger
• Regulatory evolution: While Securitize is well-positioned for current rules, regulations continue to evolve
• Accredited investor restrictions: Most Securitize offerings require accredited investor status, limiting retail access
• Competition from incumbents: The DTCC's Canton Network pilot could commoditize tokenization services

Who Should Pay Attention

Institutional allocators: If you manage institutional capital and are exploring tokenized funds, Securitize is the de facto infrastructure layer.

Crypto lending protocol developers: Integrating BUIDL and other Securitize-issued tokens as collateral could unlock institutional capital inflows.

Investors watching the tokenization trade: SECZ (when public) and FIGR (already public) are the two most direct ways to invest in the tokenization infrastructure thesis.

Crypto lending participants: Understanding how institutional tokenization infrastructure works helps you evaluate the quality and regulatory standing of tokenized assets appearing in lending protocols.
