BlackRock Files S-1 for Bitcoin Premium Income ETF as Crypto ETPs See $1.73B in Outflows

The world’s largest asset manager, BlackRock, has filed the registration statement for its Bitcoin Premium Income ETF with the U.S Securities and Exchange Commission (SEC). This move comes just as crypto ETPs log their largest weekly outflows since November last year.

BlackRock Files Registration Statement For Upcoming Bitcoin ETF

An SEC filing shows that the crypto ETF issuer has filed the S-1 for its Bitcoin Premium Income ETF, which would list on the Nasdaq. The Trust’s assets will primarily consist of BTC, shares of iShares Bitcoin Trust ETF, and cash.

BlackRock stated that the Trust will seek to track the BTC price while providing premium income through an actively managed strategy if writing call options on IBIT shares and, from time to time, on ETP indices that track spot Bitcoin ETPs, including IBIT. Furthermore, the fund will allow in-kind creations and redemptions. Top crypto exchange Coinbase will serve as the custodian of the Trust’s Bitcoin holdings, while the Bank of New York Mellon will serve as the custodian of the Trust’s cash holdings.

Meanwhile, the filing didn’t include other key details such as the ticker or the management fee. This filing comes months after Nasdaq first filed to list the iShares Bitcoin Premium Income ETF under the commodity-based trust rule.

As CoinGape reported in December last year, the SEC had already advanced the Bitcoin ETF application, instituting proceedings to determine whether to approve or disapprove it. It is worth highlighting the success that BlackRock has already achieved with its existing crypto ETFs. The asset manager is currently the largest Bitcoin ETF issuer with net assets of almost $70 billion. It is also the largest Ethereum ETF issuer with net assets of just over $10 billion.

Crypto ETPs Log their Largest Outflows Since November

BlackRock’s filing comes just as crypto exchange-traded products recorded $1.73 billion in weekly outflows, according to a CoinShares report. This marked their largest outflows since mid-November 2025. The U.S. crypto ETPs accounted for the majority of the outflows, totaling $1.8 billion.

Bitcoin and Ethereum ETPs led with outflows of of $1.09 billion and $630 million, respectively. CoinShares noted that dwindling expectations for a Fed rate cut, negative price momentum, and disappointment that crypto assets have not participated in the debasement trade yet have likely fuelled these outflows.

BlackRock’s iShares crypto ETPs recorded the largest outflows with $951 million from its BTC and ETH funds. However, the asset manager’s funds still have a year-to-date net inflow of $847 million.
