BlackRock Files 2 Tokenized Funds: BUIDL Hits $2.3B in 2026

BlackRock just expanded its tokenization product line. On May 8, 2026, the largest asset manager in the world filed applications with the Securities and Exchange Commission for two new tokenized funds, extending the BUIDL franchise that already holds 2.3 billion dollars in assets. The on-chain real-world-asset market has crossed 32 billion dollars, triple the size of one year ago. Franklin Templeton, JP Morgan and Securitize are all in the same trade. The starting gun for institutional asset tokenization has fired.

What happened

On May 8, 2026, BlackRock filed two new applications with the Securities and Exchange Commission to register tokenized fund structures. The filings come on top of the existing BUIDL fund, which has grown to approximately 2.3 billion dollars in assets and stands as the largest single tokenized treasury product in the market. The new filings are not yet approved, but the SEC has cleared similar structures from BlackRock and other major issuers over the past year, which makes approval the base case rather than the long-shot scenario.

The market response has been to treat the filings as the formal start of BlackRock's tokenization product line. Industry coverage characterized the move as a transition from pilot project to product family, signaling that the asset manager intends to maintain a permanent presence in on-chain asset management rather than running BUIDL as a one-off experiment. BlackRock CEO Larry Fink has publicly endorsed asset tokenization as the future of finance multiple times over the past two years. The May 2026 filings are the operational follow-through on that thesis.

The broader market context is that tokenized real-world assets on public blockchains crossed 32 billion dollars in May 2026, roughly tripling over the trailing twelve months. The growth is driven primarily by tokenized US Treasury funds, with BlackRock BUIDL, Franklin Templeton Benji and Ondo Finance OUSG leading by AUM. Franklin Templeton and Ondo together pushed the combined tokenized Treasury subset past key thresholds earlier in the year, and BlackRock's continued expansion is reinforcing the segment.

Why this matters now

Asset tokenization has been pitched at industry conferences for nearly a decade. What changed in 2024 and 2025 was that the largest traditional asset managers actually started shipping product. BlackRock's BUIDL launched in March 2024 with an initial 100 million dollar seed and crossed the one-billion-dollar mark within months. Franklin Templeton's Benji had been running since 2021 as one of the first regulated tokenized funds and continued to grow as institutional comfort with the structure deepened. By the start of 2025, the question was not whether asset tokenization would happen but how fast it would scale.

The May 8, 2026 filings are a structural signal that BlackRock sees enough demand to justify a product family rather than a single fund. Each new filing adds operational complexity, regulatory disclosure and ongoing compliance cost. Asset managers do not pay those costs without an internal expectation of meaningful inflows. The fact that BlackRock is willing to file twice in one day is a vote of confidence in the addressable market.

The 32 billion dollar on-chain RWA figure is itself a milestone. Twelve months earlier the market sat at roughly 11 billion dollars. Tripling in twelve months puts tokenized assets ahead of most institutional adoption curves and well above the growth rates that early-stage crypto narratives typically maintain. The growth is structurally different from speculative token cycles because the assets being tokenized are yield-bearing Treasury notes and similar instruments that generate cash flow regardless of crypto market direction.

How tokenized Treasury funds actually work

The mechanic is simpler than the marketing suggests. A tokenized Treasury fund holds a portfolio of short-duration US Treasury bills or notes, typically with average maturities between three and six months. The fund issues tokens that represent fractional ownership of that portfolio. Token holders receive yield in the form of net asset value appreciation or daily token rebases, depending on the fund's structure. Redemption is typically processed daily on traditional banking rails, with on-chain transfers happening continuously between qualified participants.

BUIDL operates on Ethereum mainnet and on additional chains added incrementally over the past year. The fund uses Securitize as the transfer agent and tokenization platform, which handles KYC, accreditation checks and the on-chain mechanics of issuance and redemption. The Securitize relationship is shared by many of the largest tokenized funds, which has made it the dominant infrastructure provider for the institutional segment.

The yield offered to token holders is approximately the Treasury yield net of fund fees. As of May 2026, that translates to roughly 4 to 4.5 percent annualized depending on the issuer. The structural attraction for crypto-native users is that the same dollar that would otherwise sit idle in a stablecoin now earns Treasury yield while remaining on-chain and usable as collateral for DeFi protocols. For institutional users, the attraction is access to short-duration Treasury exposure with 24/7 settlement and programmable transfer rails.

Franklin Templeton, Ondo and the supporting cast

BlackRock dominates by AUM but it is not alone. Franklin Templeton's Benji fund has been live since 2021 and accounts for a meaningful slice of the 7 to 9 billion dollar tokenized US Treasury subset of the broader market. Ondo Finance's OUSG, which started as a wrapped exposure to short-duration Treasury ETFs, has grown into a multi-billion-dollar product that participates directly in the same institutional flows. Together, BlackRock, Franklin Templeton and Ondo represent the bulk of the tokenized Treasury market by AUM.

JP Morgan operates a different model. The bank's Onyx Digital Assets platform handles tokenized intraday repo and tokenized collateral movements at institutional scale, processing trillions of dollars in cumulative volume since launch. The volume is not the same as AUM because it is transactional rather than custodial, but it represents another major institutional commitment to on-chain settlement that lives alongside the BUIDL-class products.

Beyond Treasuries: the next RWA frontier

Treasuries are the easiest asset class to tokenize because the underlying is uniform, liquid and well understood. The next frontier is more complex assets: tokenized equities, tokenized private credit, tokenized real estate and tokenized commodities. Each category has its own valuation, custody and regulatory wrinkles. BlackRock's May 2026 filings have not been disclosed in detail, but industry expectations are that the asset manager will extend beyond pure Treasury exposure into adjacent categories over the next 18 months.

The Pendle ecosystem, which built its DeFi business on tokenizing yield streams, has been one of the on-chain layers that benefits most from the RWA expansion. Pendle's TVL has tracked the tokenized Treasury growth curve closely because the protocol's yield-tokenization mechanic adds a second layer of utility on top of the underlying RWA exposure. The category-wide growth is creating composable financial primitives that traditional finance cannot replicate without on-chain infrastructure.

FAQ

What did BlackRock file on May 8, 2026?

Two new tokenized fund applications with the SEC, extending the BUIDL franchise that currently manages approximately 2.3 billion dollars. The specific structures have not been publicly detailed beyond the filing.

How big is the tokenized RWA market?

Over 32 billion dollars on public blockchains as of May 2026, roughly triple the size of one year ago. Tokenized US Treasury funds account for 7 to 9 billion dollars of that total.

How does a tokenized Treasury fund work?

The fund holds a portfolio of short-duration US Treasuries and issues tokens representing fractional ownership. Token holders earn yield through NAV appreciation or daily rebases. Redemption is processed daily through traditional banking rails.

Who are the main issuers besides BlackRock?

Franklin Templeton with Benji, Ondo Finance with OUSG, Securitize as the underlying infrastructure provider for many issuers, and JP Morgan via Onyx for tokenized intraday repo and collateral movements.

Is tokenized Treasury exposure safer than holding stablecoins?

Tokenized Treasury funds typically hold actual Treasury bills as collateral, which is a different risk profile than algorithmic or unbacked stablecoins. The structures are regulated and the underlying is direct US government debt. They are not risk-free because of interest rate and smart contract risk, but the credit risk is materially lower than most stablecoin alternatives.
