BlackRock BUIDL on Avalanche Hits $900M in Assets
BlackRock's BUIDL fund on Avalanche has surpassed $900 million in tokenized Treasury assets, nearly doubling from $464 million in a short period. The milestone highlights surging institutional demand for tokenized RWA products on public blockchains.

The Avalanche inflows have materially reshaped the network's tokenized asset profile. BUIDL held $624.87 million on Avalanche as of the May 25, 2026 snapshot, according to The Defiant, which cited RWA.xyz data. That concentration drove Avalanche's total distributed RWA value to a record $1.16 billion in late May, with the network's RWA TVL rising 58.4% over the two weeks ending May 25. The second-largest RWA position on Avalanche at that date was Janus Henderson's Anemoy AAA CLO Fund at $258.99 million, underscoring how concentrated the network's tokenized asset base remains around BUIDL.
BUIDL's multi-chain architecture spans Ethereum, Aptos, Arbitrum, Avalanche, Optimism, and Polygon, with cross-chain interoperability handled by Wormhole. Custody for fund subscribers is provided by Anchorage Digital, BitGo, Copper, and Fireblocks, among others, while Bank of New York Mellon serves as cash and securities custodian. The official Securitize press release noted that BUIDL had already crossed $1 billion in total AUM as of March 2025, identifying treasury management, stablecoin backing, DeFi access, and trading collateral as the primary institutional use cases.
By Q2 2026, Altrady's aggregation placed BUIDL's total AUM at approximately $2.4 billion, a figure that the CoinSpectator snapshot from July 12 revised upward to approximately $2.87 billion following the latest Avalanche inflows. BlackRock separately filed with the SEC on May 8, 2026 for two new tokenized funds and on-chain shares for a $7 billion money-market fund, according to Altrady, indicating that the Avalanche allocation is one component of a broader institutional tokenization program rather than an isolated product decision.
The fund's yield profile, reported by Altrady at 4.5–5.0% APY based on short-duration T-bill rates at the time of publication, has been a key driver of institutional uptake for treasury management applications. BlackRock manages approximately $11 trillion in assets globally, and BUIDL represents a small but structurally significant portion of the firm's effort to bring traditional fixed-income exposure on-chain for institutional counterparties.
What remains unclear: The available sources do not identify which specific institutional counterparties drove the $436 million single-week inflow to Avalanche, nor do they disclose whether those allocations came from new subscribers or existing holders rebalancing across chains. The announcements do not specify the minimum subscription size for Avalanche-based access, the fee structure applied to Avalanche deployments relative to Ethereum, or the redemption mechanics and settlement timelines specific to the Avalanche instance. The May 2026 SEC filings for the two additional tokenized funds have not been accompanied by public disclosure of fund mandates, target AUM, or launch timelines.
The immediate operational effect of the July 2026 data is that BUIDL's Avalanche allocation now exceeds $900 million and constitutes the dominant RWA position on that network. The available sources do not establish whether the $900 million threshold triggers any structural changes to the fund's custodial arrangements, chain-specific liquidity provisions, or Wormhole interoperability parameters, and no regulator has publicly commented on the concentration of a single tokenized Treasury product across Avalanche's RWA market.
