BlackRock Crypto: From Bitcoin ETF to Tokenized Fund

BlackRock crypto products give investors regulated Bitcoin access and on-chain yield — IBIT leads all spot Bitcoin ETFs with $62.5B in cumulative inflows.

Introduction

BlackRock, the world's largest asset manager with $14 trillion in assets under management as of end-2025, has built the most extensive digital asset infrastructure among traditional finance firms. The firm operates two distinct products: the iShares Bitcoin Trust (IBIT), a spot Bitcoin exchange-traded fund launched on 11 January 2024, and the BlackRock USD Institutional Digital Liquidity Fund (BUIDL), a tokenized money market fund launched on 20 March 2024. Together, these products represent a deliberate two-track strategy — one providing regulated Bitcoin exposure to mainstream investors, the other converting traditional financial instruments into programmable blockchain tokens for institutional use.

IBIT reached $10 billion in assets under management in just 37 trading days — the fastest any ETF in history has hit that mark — and accumulated approximately $62.5 billion in cumulative net inflows since launch. BUIDL followed a parallel trajectory, growing from its Ethereum-only launch to deployment across eight blockchains and surpassing $2.5 billion in assets under management by early 2026.

This article explains how each product works, what makes BlackRock's multi-chain tokenization strategy structurally different from competing approaches, and why the firm's active engagement with the U.S. Securities and Exchange Commission (SEC) shapes standards for the entire digital asset industry.

How Does the iShares Bitcoin Trust (IBIT) Work and What Are Its Key Metrics?

Structure and Mechanics

The iShares Bitcoin Trust (IBIT) is a spot Bitcoin ETF — an exchange-traded fund that holds actual Bitcoin rather than futures contracts. IBIT shares trade on the Nasdaq exchange, giving investors direct Bitcoin price exposure through a standard brokerage account. BlackRock launched the fund on 11 January 2024, following U.S. Securities and Exchange Commission (SEC) approval alongside nine other spot Bitcoin ETFs.

The fund uses a grantor trust structure, meaning each share represents a proportional ownership stake in the underlying Bitcoin held by the trust. Authorized participants — large financial institutions — create and redeem shares in exchange for cash or Bitcoin, keeping the market price close to the fund's net asset value. BlackRock partners with Coinbase Custody Trust Company (also called Coinbase Prime) to store all Bitcoin in cold storage, meaning entirely offline wallets secured with multi-signature authorization.

Key Performance Metrics

IBIT carries an annual expense ratio of 0.25%, which is the ongoing fee investors pay for fund management. The fund accumulated approximately $62.5B in cumulative net inflows since its January 2024 launch, capturing roughly 55% of the spot Bitcoin ETF market as of late 2025. In 2025 alone, IBIT ranked sixth globally across all ETF categories by net inflows, pulling in approximately $25B despite posting a negative annual return — a rare combination for a top-ten fund.

Data current as of April 2026.

IBIT's AUM lead over the next-largest competitor reflects both BlackRock's established distribution network and the institutional trust the brand carries. The fund holds Bitcoin in segregated wallets, separate from Coinbase's proprietary holdings, which provides transparent on-chain proof of reserves. This custody structure has become the de facto standard that newer spot Bitcoin ETFs, including Morgan Stanley's MSBT launched in April 2026, now benchmark against.

What Is the BUIDL Fund and How Does Tokenization of Real-World Assets Work?

Defining Tokenization

Tokenization is the process of converting ownership rights in a real-world asset into a digital token recorded on a blockchain. Instead of a paper certificate or a database entry at a central broker, a token on a public blockchain acts as the legal and functional proof of ownership. This approach makes assets programmable — they can settle instantly, pay yield automatically, and transfer between wallets without an intermediary clearing the transaction.

Real-world assets available for tokenization include U.S. Treasury bills, corporate bonds, real estate, and private equity. Tokenized money market funds represent the most mature and liquid category today, because short-term government debt is stable in value and already highly regulated. BlackRock's BUIDL fund sits at the centre of this category.

How BUIDL Works

BlackRock launched the BlackRock USD Institutional Digital Liquidity Fund (BUIDL) on the Ethereum blockchain on 20 March 2024, in partnership with Securitize — an SEC-registered transfer agent and tokenization platform. The fund holds cash, U.S. Treasury bills, and short-term repurchase agreements as its underlying assets, with Bank of New York Mellon (BNY Mellon) serving as custodian and administrator. Securitize mints one BUIDL token for every one U.S. dollar subscribed, maintaining a stable $1.00 token price while yield accrues daily to holders' wallets.

Only qualified purchasers — institutions or high-net-worth individuals meeting regulatory thresholds under Section 3(c)(7) of the U.S. Investment Company Act — can invest, with a minimum subscription of $5 million. Investors wire U.S. dollars to BNY Mellon, BlackRock deploys those funds into Treasury markets, and Securitize issues the corresponding BUIDL tokens to the investor's whitelisted blockchain wallet. Token holders receive daily yield accrual and can transfer tokens peer-to-peer, 24 hours a day, seven days a week — a settlement speed that conventional T+1 or T+2 fund operations cannot match.

Scale and Milestones

BUIDL reached $1.7 billion in assets under management by March 2025, when Securitize added Solana as the fund's seventh supported blockchain. By early 2026, independent data sources reported BUIDL's AUM had grown beyond $2.5 billion, confirming its position as the world's largest tokenized money market fund. In December 2025, BUIDL became the first tokenized fund to distribute $100 million in cumulative on-chain dividends to token holders.

The fund's structure also enables BUIDL tokens to function as on-chain collateral. Institutional counterparties on platforms such as Binance, Deribit, and Crypto.com accept BUIDL tokens in lieu of cash margin, increasing capital efficiency for institutional trading desks. This collateral utility transforms BUIDL from a passive yield instrument into active financial infrastructure within digital asset markets.

What Are the Different Blockchains BUIDL Operates On and Why Does Multi-Chain Matter?

The Multi-Chain Rationale

BUIDL launched exclusively on Ethereum in March 2024, but a single-blockchain approach limits the fund to investors and developers already operating on that network. BlackRock and Securitize addressed this constraint through two expansion rounds — adding five blockchains on 13 November 2024 and Solana on 25 March 2025. BNB Chain joined the network in November 2025, bringing the total to eight blockchains across Layer 1 and Layer 2 networks.

Each blockchain added extends BUIDL's reach into a distinct investor and developer community. BlackRock CEO Larry Fink cited approximately $4.1 trillion sitting in global digital wallets as of October 2025, and positioned multi-chain deployment as the primary mechanism to access these assets for institutional investment products. Cross-chain token transfers rely on Wormhole, an interoperability protocol that enables BUIDL tokens to move securely between supported networks without requiring a centralised bridge.

Chain-by-Chain Breakdown

Each blockchain in the BUIDL ecosystem serves a distinct institutional purpose. Ethereum provides deep DeFi (decentralised finance) composability — the ability to plug BUIDL tokens directly into on-chain lending, trading, and collateral protocols. The five networks added in November 2024 target either institutional infrastructure (Avalanche, Aptos) or Ethereum scalability solutions that reduce transaction costs and confirmation times.

Data current as of April 2026.

The BNB Chain integration marked a strategic shift beyond distribution. Binance simultaneously approved BUIDL tokens as off-exchange collateral for derivatives trading on its platform. This means institutions holding BUIDL earn Treasury yield on capital that simultaneously backs margin positions — eliminating the opportunity cost of posting idle cash as collateral. Competitors offering single-chain or custodian-only tokenized products cannot replicate this capital efficiency without comparable multi-chain infrastructure.

How Does BlackRock's Four-Stage Tokenization Vision Reshape Traditional Finance?

Fink's Strategic Declaration

In an October 2025 interview on CNBC, BlackRock chairman and CEO Larry Fink stated the financial industry stands at "the beginning of the tokenization of all assets" — explicitly naming real estate, equities, and bonds as targets. Fink's April 2025 annual letter to investors reinforced this commitment, stating "every asset can be tokenized" and describing the shift as a "revolution" in investing that would enable around-the-clock markets and near-instant settlement. These statements reflect a structural strategic position, not a speculative forecast — BlackRock already manages live tokenized products across eight blockchains.

The scale of the opportunity Fink describes is measurable. Global real estate represents approximately $630 trillion in total value, global bond markets approximately $150 trillion, and public equity markets approximately $111 trillion. Even a 1% tokenization rate across those three asset classes would create a digital asset market roughly three times larger than the entire crypto market as of early 2026.

Four Stages of Execution

BlackRock's tokenization strategy unfolds across four sequential stages, each building on the infrastructure and regulatory precedents established by the previous one.

Stage 1 — Cash and Stable Instruments (live): The BUIDL fund operates in this stage, converting U.S. Treasury bills and cash instruments into on-chain tokens. Tokenized Treasury and money-market fund assets grew to $7.4 billion across the industry in 2025, an 80% increase year-on-year, with BUIDL holding the largest share. This stage proved that institutional compliance, on-chain yield, and 24/7 transferability can coexist within existing U.S. securities law.

Stage 2 — Fixed Income (early deployment): Tokenized government and corporate bonds are the next logical step, as debt instruments carry fixed cash flows that translate directly into programmable on-chain payments. The total tokenized bond market reached approximately $6.5 billion in mid-2025, with U.S. Treasuries comprising the majority. BlackRock's BUIDL structure provides the custody and transfer-agent framework this stage requires.

Stage 3 — Expanding the Asset Universe (exploratory): Private credit, commodities, and real estate tokenization are emerging across specialised platforms. Private credit reached $12.9 billion in tokenized value by mid-2025, while tokenized real estate stood at approximately $3.8 billion. BlackRock has invested in Securitize and Ondo Finance — two platforms building infrastructure for this stage.

Stage 4 — Full On-Chain Capital Markets (future): This stage envisions publicly traded equities, private equity, and real estate investment trusts settling entirely on-chain with real-time ownership records. No major jurisdiction has established the legal framework required for this stage as of April 2026. Fink identified digital identity verification as the single most critical prerequisite — without it, regulators cannot enforce know-your-customer rules across open blockchain networks.

Why This Reshapes Traditional Finance

On-chain capital markets eliminate several cost layers embedded in today's financial infrastructure. T+0 settlement — completing a trade in the same second rather than one or two business days — frees collateral that currently sits idle during settlement windows, which the Bank for International Settlements estimates ties up hundreds of billions of dollars daily. Fractional ownership allows investors to buy a proportional share of a single bond or a commercial property, removing the high minimum ticket sizes that currently restrict access to institutional-grade assets.

BlackRock's four-stage model gives regulators, custodians, and asset managers a sequenced adoption path rather than a sudden disruption. Each stage generates operational data and legal precedents that reduce the risk profile of the next stage — a deliberate design that positions BlackRock as the trusted architect of digital capital markets infrastructure, not merely a participant.

What Are the Benefits and Risks of BlackRock's Crypto and Tokenization Strategy?

The Strategic Benefits

BlackRock's dual crypto strategy — IBIT for market access and BUIDL for tokenization — delivers four structural improvements over traditional financial products. First, both products operate 24 hours a day, seven days a week, while conventional fund transfers and ETF secondary trading are limited to exchange hours. Second, BUIDL's tokenized structure allows fractional ownership — institutions can allocate precise dollar amounts to a money-market instrument rather than buying fixed-denomination Treasury bills. Third, on-chain settlement reduces the standard T+1 or T+2 trade settlement window to near-instant execution, freeing capital that currently sits idle waiting for clearing. Fourth, every BUIDL token transfer is recorded on a public blockchain, creating an immutable audit trail that reduces reconciliation costs for back-office operations.

IBIT offers a distinct benefit for capital markets infrastructure. BlackRock controls approximately 96% of net spot Bitcoin ETF trading volume among institutional products as of early 2026, which concentrates liquidity and narrows bid-ask spreads for all market participants. The SEC's approval to increase IBIT options position limits from 250,000 to 1,000,000 contracts also gives institutional traders more efficient hedging tools, reducing Bitcoin's overall price volatility during stress events.

Key Risks and Mitigations

BlackRock's crypto strategy carries five categories of risk that investors and regulators monitor closely.

Data current as of April 2026.

Smart contract risk deserves particular attention for BUIDL. A software vulnerability in the Securitize token contract or the Wormhole cross-chain bridge could allow an attacker to mint unauthorised tokens or freeze legitimate transfers. Securitize mitigates this through mandatory third-party code audits and maintaining a whitelist of approved wallet addresses — only verified institutional wallets can receive BUIDL tokens, limiting the attack surface compared to fully public DeFi protocols.

Custody concentration in IBIT presents a systemic risk. Coinbase Prime holds Bitcoin for IBIT and four of the five largest competing spot Bitcoin ETFs. A technical failure, regulatory action, or solvency event at Coinbase could simultaneously affect multiple products. BlackRock discloses this risk in IBIT's SEC-filed prospectus and maintains segregated wallet architecture as the primary mitigation. The SEC's ongoing Crypto Task Force discussions include custody standards for digital asset ETFs — a regulatory clarification that could prompt diversification of custodian arrangements across the industry.

How Does BlackRock Engage With Regulators on Crypto Policy and What Standards Is It Proposing?

Direct SEC Engagement

BlackRock met with the SEC's Crypto Task Force — a dedicated regulatory working group established in early 2025 — on two separate occasions within six weeks. The first meeting took place on 1 April 2025, focusing on the mechanics of in-kind redemptions for Bitcoin ETPs and staking treatment within exchange-traded products. The second meeting on 9 May 2025 expanded the agenda to include tokenization of securities, staking capabilities for ETPs, and criteria for approving new crypto exchange-traded products.

These meetings produced concrete regulatory outcomes. On 29 July 2025, the SEC voted to approve in-kind creations and redemptions for crypto ETPs, explicitly citing the efficiency and cost savings the structure provides — a direct outcome of the industry engagement BlackRock helped lead. Under in-kind redemption, authorised participants exchange ETF shares directly for Bitcoin rather than cash, eliminating the taxable sale event that cash redemption triggers and improving the fund's price-tracking accuracy. BlackRock subsequently amended its iShares Ethereum Trust (ETHA) S-1 filing to incorporate in-kind redemption as an alternative to the existing cash-only process.

Proposed Industry Standards

At the 9 May 2025 meeting, BlackRock presented a framework for interim standards that the SEC could apply to crypto ETP issuers ahead of broader formal rulemaking. The proposal asked the SEC to codify specific criteria under Section 6(b) of the Exchange Act — the statutory provision governing exchange listing requirements — to evaluate whether a crypto ETP satisfies market integrity and investor protection thresholds. These criteria would cover pricing mechanisms, custody arrangements, and surveillance-sharing agreements, creating a consistent baseline across all crypto ETP applicants rather than a case-by-case review process.

BlackRock also addressed staking — the process of locking proof-of-stake cryptocurrency to validate transactions and earn protocol rewards — as a potential feature for ETPs holding assets like Ethereum. The firm requested guidance on whether staking revenues could be passed through to ETP shareholders without triggering additional securities classification issues, and how staked assets would be treated during redemption windows when assets must remain locked for validator exit queues. The SEC had not issued a formal ruling on ETP staking as of April 2026, but the September 2025 approval of generic listing standards for commodity-based ETPs including crypto assets signalled continued regulatory openness.

Why This Engagement Shapes Industry Norms

BlackRock's regulatory participation carries weight that smaller crypto-native firms cannot replicate. The firm manages over $11 trillion in assets under management as of early 2026 and operates under the same securities law framework as the ETPs it is proposing to standardise. When BlackRock proposes interim ETP criteria, SEC staff treat those proposals as informed industry input grounded in decades of ETF operations, custody experience, and compliance infrastructure — accelerating the SEC's own internal standard-setting process. The standards BlackRock advocates for — transparent pricing benchmarks, segregated custody, clear staking treatment — reflect the operational baseline already embedded in IBIT and BUIDL, giving the firm a structural advantage when regulators formalise requirements that BlackRock's products already meet.

How Does BlackRock's Digital Asset Strategy Compare to Competitors in Traditional Finance?

The TradFi Digital Asset Landscape

BlackRock is not the only traditional asset manager building digital asset products, but it leads the field by a measurable margin across every key metric. Four peers — Fidelity, Franklin Templeton, State Street, and Vanguard — have each taken distinct positions ranging from full product development to deliberate abstention. Understanding where each firm stands clarifies why BlackRock's first-mover advantage in both the Bitcoin ETF and tokenized fund categories is structurally difficult to replicate.

Fidelity is the closest competitor. The Fidelity Wise Origin Bitcoin Fund (FBTC) launched on 11 January 2024 alongside IBIT, uses Fidelity Digital Assets as its in-house custodian, and carries the same 0.25% expense ratio. FBTC held approximately $13.9 billion in AUM as of early 2026 — significant in absolute terms but roughly one-seventh of IBIT's asset base. Fidelity has not launched a tokenized money market fund in the United States as of April 2026, leaving the tokenization segment entirely to competitors.

Franklin Templeton holds the earliest-mover advantage in tokenized funds. Its Franklin OnChain U.S. Government Money Fund (FOBXX), distributed via the BENJI platform, launched in 2021 — three years before BUIDL — as the first U.S.-registered mutual fund to use a public blockchain as its official record-keeping system. BENJI reached approximately $690 million in AUM across eight blockchains as of August 2025, compared to BUIDL's $2.5 billion-plus by early 2026. Franklin Templeton has no spot Bitcoin ETF in the U.S. market, limiting its digital asset footprint to the tokenization segment.

Competitor Positioning Table

Data current as of April 2026.

Where BlackRock's Lead Is Structural

BlackRock's simultaneous leadership in both the ETF and tokenized fund segments reflects two compounding advantages. First, the firm's distribution network — covering pension funds, sovereign wealth funds, and retail brokerage platforms in over 30 countries — gives new products immediate global reach that Franklin Templeton and Fidelity cannot match at equivalent scale. Second, BlackRock's active SEC engagement has positioned IBIT and BUIDL as the operational benchmarks regulators reference when designing new rules, creating a self-reinforcing standard-setting loop.

State Street's 2025 digital assets survey found that 60% of institutional investors plan to increase their digital asset exposure beyond 2% of portfolio within the next year. State Street itself, however, has remained in a custodian and infrastructure role rather than launching investor-facing products — a position that generates fee revenue but cedes product leadership entirely to BlackRock and Fidelity. Vanguard's explicit refusal to offer Bitcoin ETF access reflects its index-fund philosophy that crypto assets lack intrinsic cash flows, a view that has cost it measurable fee revenue as IBIT alone generated more annual revenue than BlackRock's flagship S\&P 500 ETF by late 2025.
