BlackRock filed SEC paperwork on May 8 to launch a new "Daily Reinvestment Stablecoin Reserve Vehicle" with OnChain Shares and add an onchain share class to its $7 billion Select Treasury Based Liquidity Fund, using Ethereum ERC-20 tokens. The moves deepen the $14 trillion asset manager's tokenization push as the real-world asset market crosses $30 billion, up 200% year-over-year.
BlackRock filed SEC paperwork on May 8 to launch a new "Daily Reinvestment Stablecoin Reserve Vehicle" with OnChain Shares and add an onchain share class to its $7 billion Select Treasury Based Liquidity Fund, using Ethereum ERC-20 tokens. The moves deepen the $14 trillion asset manager's tokenization push as the real-world asset market crosses $30 billion, up 200% year-over-year.
BlackRock, the world's largest asset manager with $14 trillion in assets, filed two separate SEC documents on May 8, 2026, to expand its tokenized fund lineup:
New fund: BlackRock Daily Reinvestment Stablecoin Reserve Vehicle — A new fund investing in cash, short-term U.S. Treasury securities, and overnight repurchase agreements backed by Treasuries. The fund would issue "OnChain Shares" through a permissioned system connected to multiple public blockchains. Securitize Transfer Agent LLC will maintain official ownership records. Minimum investment: $3 million.
New share class: BlackRock Select Treasury Based Liquidity Fund — OnChain Shares — An onchain share class for the existing BlackRock Select Treasury Based Liquidity Fund, which holds nearly $7 billion in assets. BNY Mellon Investment Servicing would maintain official ownership records on Ethereum using ERC-20 token standards. Blockchain records combined with offchain identity systems linking wallets to investors would serve as the official shareholder registry.
Neither filing disclosed which specific blockchains the Stablecoin Reserve Vehicle would initially support. The filings are subject to completion, dated May 8, 2026.
This is BlackRock's most significant tokenization move since launching BUIDL in 2024 — and it's happening in two directions simultaneously.
The Stablecoin Reserve Vehicle is a purpose-built onchain product. It's designed from the ground up for the tokenized world: cash, Treasuries, repos, all recorded on public blockchains through Securitize. This is the infrastructure layer for stablecoin-backed DeFi — a regulated, BlackRock-quality reserve asset that can serve as the backbone for onchain lending, borrowing, and payments.
But the $7 billion fund's onchain share class is arguably the bigger signal. BlackRock isn't creating a new crypto-native product — it's taking an existing, traditional, $7 billion money market fund and adding blockchain-native ownership. BNY Mellon, one of the oldest and largest custodian banks in the world, will maintain the official shareholder registry on Ethereum. That's not experimentation. That's infrastructure.
Combined, the moves suggest BlackRock is moving from "crypto pilot" to "blockchain as settlement layer." When the world's largest asset manager starts putting $7 billion traditional fund shares on Ethereum, the question isn't whether tokenization will happen — it's how fast everything else follows.

|---|---|---|---|
| Type | Tokenized money-market fund | New onchain stablecoin reserve | Onchain share class of existing fund |

| Transfer Agent | Securitize | Securitize | BNY Mellon |
| Min Investment | $100K (approx) | $3M | Standard institutional |
| Significance | First BlackRock onchain fund | Purpose-built for stablecoin ecosystem | First onchain share class of traditional fund |
BlackRock CEO Larry Fink has repeatedly called tokenization the future of financial infrastructure. These filings show he's putting the firm's money — literally trillions of it — behind that vision.
The timing is not coincidental. The tokenized real-world asset market has grown 200% in a year to exceed $30 billion. The DTCC is launching its tokenized securities platform in October. Securitize and Computershare are working to bring $70 trillion in U.S. stocks on-chain. The SEC under Chair Paul Atkins has signaled support for onchain trading and blockchain settlement infrastructure. Every major piece of U.S. market infrastructure is moving toward blockchain-based settlement.
BlackRock's dual filing strategy is the clearest signal yet of how this plays out. New crypto-native products (like the Stablecoin Reserve Vehicle) will coexist with the tokenization of existing traditional products (like the $7B money market fund). The latter is where the real scale is — $7 billion in one fund, $14 trillion across the firm.
For context on the scale of what's being built: the global money market fund industry holds roughly $10 trillion. If even 10% of that eventually moves on-chain through structures like BlackRock is building, we're talking about a $1 trillion onchain money market ecosystem. BUIDL at $2.5 billion is the seed. These new filings are the irrigation system.
Securitize (NYSE: SECZ, ~$5B AUM) launched Securitize Stocks today at 13:00 UTC: 12 tokenized US mega-caps — including Apple, Microsoft, Nvidia, Tesla, Circle, Strategy and Palantir — each backed 1:1 by a real share, settling in USDC on Solana with Jump Trading running the proprietary AMM and clearing firm RQD* handling custody and settlement. It is the first product live under the SEC's five-year Innovation Exemption for onchain stock trading, granted September 17.
Anthropic's much-anticipated IPO prospectus — reported in detail by Reuters and the Financial Times — pursues a $2 trillion valuation while disclosing a $42 billion net loss for 2025 and plans to spend $518 billion on cloud, computing, and infrastructure in the coming year. Roughly 80 of the filing's 261 main-body pages cover risk factors, including that advanced AI could pose 'catastrophic or existential risks to humanity,' versus 48 pages describing the business. Nvidia separately disclosed that Anthropic has more than $180 billion in contracted compute commitments — 2.5GW of Nvidia infrastructure shipping through 2028.
Nvidia's board authorized an additional $150 billion in share repurchases on Monday — which the company says is the largest single authorization increase ever announced by a public company — lifting total remaining buyback capacity to $235 billion, expected to be spent through fiscal 2028. NVDA rose 2.8% to a $5.42 trillion market cap as Jensen Huang called AI 'a once-in-a-generation platform shift.'
