BlackRock’s $2.5B BUIDL Fund Extends Into Binance and BNB Chain Amid Rising Institutional Demand

BlackRock Expands Tokenized Treasury Access Through Binance’s Off-Exchange Collateral Model

TL;DR

• BlackRock’s $2.5 billion BUIDL fund is now accepted as off-exchange collateral on Binance and launches a new share class on BNB Chain.
• Institutions gain on-chain access to a regulated, yield-bearing Treasury fund they can use for trading collateral without transferring assets onto the exchange.
• The expansion underscores a broader shift toward tokenized real-world assets as capital-efficient tools in modern markets tracked across every major crypto price index.

BlackRock’s USD Institutional Digital Liquidity Fund, widely referred to as BUIDL, advanced its tokenization roadmap on November 14, 2025, through a coordinated rollout with Binance and BNB Chain that brings the $2.5 billion Treasury-backed vehicle deeper into the digital asset ecosystem. The move places BUIDL inside Binance’s off-exchange collateral architecture, enabling institutions to pledge tokenized shares of the fund through regulated triparty banking partners and Ceffu custody while trading on the exchange without shifting assets onto its books. The new design reflects growing demand among institutional desks for interest-bearing collateral options that maintain regulatory consistency while slotting directly into digital trading workflows, all occurring during a period of heightened attention to crypto price movements and expanding coin market cap rankings across the broader market.

A dedicated BNB Chain share class accompanies the integration, turning BUIDL into an officially supported asset on the network rather than a bridged representation. Qualified investors can hold the tokenized fund on a low-cost EVM chain built for financial applications, gaining access to 24/7 peer-to-peer transfers and daily dividend distribution from its underlying short-term U.S. Treasury strategy. The expansion continues BUIDL’s multi-chain footprint—already live across Ethereum, Solana, Avalanche, Aptos, Arbitrum, Polygon, and Optimism—and reinforces BlackRock’s intention to make tokenized real-world assets a standard component of on-chain financial infrastructure. The fund debuted in March 2024 and has grown to roughly 93 on-chain holders, a number that underscores its institutional focus rather than broad retail reach.

BlackRock’s head of digital assets, Robbie Mitchnick, framed the integration as part of a broader mission to transplant key structural components of traditional finance into blockchain-based markets, describing BUIDL’s new role as a building block for capital-efficient trading systems. Binance’s institutional lead Catherine Chen echoed that dynamic, noting that clients have increasingly requested yield-bearing collateral formats that align with internal compliance frameworks while remaining operationally compatible with high-volume trading. BNB Chain leadership highlighted the network’s suitability for institutional-grade financial products, positioning BUIDL as evidence that tokenized assets are evolving from conceptual experiments to programmable investment instruments used in real strategies.

Yield performance factored into the announcement as well: data cited across the reports pointed to roughly 3.7% annualized returns over the prior week, consistent with Treasury-linked products and increasingly scrutinized by investors benchmarking returns across every major crypto price index. Securitize, the tokenization platform issuing BUIDL, now oversees more than $4 billion in tokenized assets and emphasized that bringing regulated real-world assets on-chain unlocks forms of utility that remain inaccessible in traditional environments. The expansion also arrives during a moment when the real-world-asset market on public blockchains is estimated to exceed $36 billion, reflecting rapid institutional momentum that tracks alongside shifts in crypto price dynamics and overall coin market cap positioning throughout the sector.

Market context surfaced through Decrypt’s coverage, which observed that BNB traded near $924 at the time, up 48% year-over-year after setting an all-time high near $1,370 the previous month, providing a backdrop for the chain’s heightened visibility. While not central to the fund integration, the pricing data helped frame investor sentiment as large-scale tokenization initiatives intersect with broader market cycles. The collaboration between BlackRock, Binance, BNB Chain, and Securitize signals a maturing environment where traditional capital structures, compliant custody, and blockchain settlement frameworks converge, laying groundwork for expanded collateral standards and new multi-chain liquidity models that are likely to shape institutional behavior across digital markets.
