Key Takeaways
BlackRock’s USD Institutional Digital Liquidity Fund, known as BUIDL, crossed $900 million in assets on Avalanche this week after adding approximately $436 million in a single seven-day period, the largest weekly inflow the fund has recorded on any individual chain since its March 2024 launch.
Total BUIDL assets under management across all supported networks reached approximately $2.87 billion following the inflow, cementing its position as the largest tokenized US Treasury product.
The Avalanche position alone now represents roughly 31% of BUIDL’s total assets. That concentration is notable given that Avalanche ranks 12th by total DeFi value locked at approximately $563 million, a relatively modest figure.
On tokenized real-world asset distribution, however, Avalanche now trails only Ethereum among permissionless networks, a ranking driven entirely by BUIDL’s allocation rather than by the chain’s broader DeFi ecosystem. RWA.xyz lists 113 BUIDL holders globally, meaning the $900 million Avalanche position reflects a small number of large institutional allocations rather than broad retail participation.
BUIDL launched in March 2024 with initial assets exceeding $500 million, making it one of the largest day-one launches in tokenized asset history. It crossed $1 billion within weeks, $2 billion by late 2025, and $2.5 billion by early 2026.
The pace of growth has not slowed. In May 2026, BlackRock filed with the SEC for two additional tokenized funds alongside onchain shares for a separate $7 billion money market fund, signaling that BUIDL is a beachhead rather than a destination.
The fund operates across nine blockchain networks, including Ethereum, Avalanche, Polygon, Optimism, Arbitrum, Aptos, and others, with Securitize serving as the tokenization partner and transfer agent.
Each BUIDL token represents one share of the fund, with a stable $1 value, and pays daily accrued dividends directly to investor wallets. The current yield reflects short-term US Treasury rates of approximately 4.5% to 5.0% annually.
BUIDL’s role has expanded beyond simple yield-bearing collateral. Ethena Labs uses BUIDL as the primary reserve asset for its USDtb stablecoin, which is now integrated into BlackRock’s own Aladdin portfolio management platform serving over $20 trillion in institutional assets.
Frax Finance and Ondo Finance both hold BUIDL as reserve collateral. Binance accepted BUIDL as margin collateral for institutional trading accounts. Each integration multiplies BUIDL’s utility beyond a simple money market product into programmable financial infrastructure.
BUIDL’s Avalanche milestone lands inside an accelerating broader trend. Tokenized US Treasuries grew from approximately $380 million in early 2023 to over $14.6 billion by mid-2026, a roughly 38-fold increase over three years.
Total tokenized real-world assets excluding stablecoins crossed $30 billion in 2026, with six distinct asset classes now above $1 billion onchain individually. Franklin Templeton’s FOBXX, Ondo Finance’s OUSG, and Fidelity International’s FILQ all crossed meaningful size thresholds in the same period, but none approaches BUIDL’s scale.
BCG projects the global tokenized asset market could reach $16 trillion by 2030. McKinsey’s estimate sits near $2 trillion by the same date.
The gap between the two forecasts reflects uncertainty about institutional adoption velocity rather than disagreement about direction. BUIDL’s current trajectory, adding $436 million on a single chain in a single week with total assets near $3 billion, is tracking closer to the higher end of that range than anyone projected when the fund launched 27 months ago.
AVAX trades at $6.50 on July 13, down approximately 85% from its November 2021 all-time high of $144.96. Despite Avalanche now ranking second only to Ethereum in tokenized RWA distribution, AVAX has not reflected that positioning in price.
Institutional capital flowing into BUIDL on Avalanche buys exposure to BlackRock’s fund, not to the chain’s native token. Until tokenized asset activity generates fee revenue that accrues meaningfully to AVAX holders, the price and the institutional narrative will likely remain disconnected.
