BlackRock's BUIDL Gains Weekend USDC Exit via Securitize and Ethena

BlackRock's tokenized money-market fund BUIDL now offers investors a way out on weekends. Securitize operates the new liquidity facility. Ethena backs it. The two firms announced the arrangement on Friday, and it changes something basic about how tokenized funds behave when traditional markets close.

The facility carries a $100 million cap. It launches with $50 million on hand — $25 million in USDC and $25 million in BUIDL. A second $50 million can arrive within roughly an hour if demand calls for it, though a footnote in the release notes that top-ups depend on the facility's terms, capacity and availability.

For years, BUIDL holders have lived with a split personality. Whitelisted investors can send tokens to each other on-chain around the clock, seven days a week. Cashing out to dollars is another matter. Redemptions happen on the same day or the next redemption date, depending on when the request lands, and the process hinges on business days. That means a Saturday holder waited until Monday. Not anymore.

Why this matters for tokenized funds

BUIDL aims for a stable $1 net asset value but does not guarantee it. The fund holds overnight repo agreements and three-month Treasuries, and only whitelisted investors who pass KYC and AML checks can access its tokens. That regulatory wrapper is what makes weekend liquidity hard. Dollars settle when banks are open.

The new facility sidesteps the problem by paying out in USDC, Circle's dollar-backed stablecoin, which settles on-chain at any hour. Eligible investors gain access through the framework Ethena secured in its expanded deal with BlackRock. BlackRock's Aladdin platform added Ethena's USDe in June, and Cryptopolitan previously reported Ethena would back a $100 million liquidity facility via Securitize.

"Tokenization is about more than putting assets onchain. It's about making those assets more useful," said Carlos Domingo, co-founder and CEO of Securitize.

"Digital assets operate around the clock, and institutional liquidity needs to keep pace," said Guy Young, founder of Ethena Labs.

What does this change for institutional investors?

The practical answer is redemption timing. An eligible BUIDL holder who needs liquidity on a Saturday or Sunday no longer waits for Monday's market open. The exit runs through USDC, which the investor can then move or convert as needed. That narrows the gap between a fund that lives on a blockchain and cash that moves through the banking system.

The deal also deepens an existing relationship. Securitize and Ethena already collaborate on USDtb, Ethena's digital dollar, which is backed by BlackRock's BUIDL. The new weekend facility extends that stack from issuance into liquidity provision.

Securitize's broader position

Securitize went public through a SPAC merger with Cantor Equity Partners II and now trades on the New York Stock Exchange under the ticker SECZ. As of September, the firm held roughly $5 billion in tokenized assets. Its other tokenized fund partners include Apollo, BNY, Hamilton Lane, KKR and VanEck.

Its stock closed at $8.39 on Thursday, down about 7.4%, so the announcement lands against a soft trading backdrop for the company's shares.

The road ahead

The $100 million cap sets a hard boundary on how much weekend demand the facility can absorb, and the fine print leaves room for top-ups to stall. But if weekend redemption in USDC proves durable, expect other tokenized-fund issuers to face pressure to match it — and the gap between on-chain settlement and banking hours will keep narrowing, one facility at a time.
