• BlackRock files iShares Bitcoin Premium Income ETF as crypto ETP outflows hit their highest level since November 2025 peak.
• The ETF targets Bitcoin exposure with monthly income using covered call options during a period of weak market flows.
• BlackRock expands its crypto ETF lineup while keeping long term inflows positive despite short term withdrawals.

BlackRock has filed a registration statement for an iShares Bitcoin Premium Income ETF with the U.S. Securities and Exchange Commission. The filing arrives as crypto exchange traded products post their largest weekly outflows since November 2025. An SEC document confirms the S-1 filing for a fund expected to list on Nasdaq. The trust plans exposure to Bitcoin alongside related instruments and cash. Therefore, the timing places product development against a cooling flow backdrop.

The filing outlines a structure focused on Bitcoin exposure with an income component. Meanwhile, market data shows broad investor pullbacks across major crypto funds. Consequently, the proposal highlights a shift toward income oriented strategies during volatility. The document did not disclose a ticker or management fee. However, it confirmed operational partners and portfolio construction.

Fund Structure and Income Strategy Details

The trust assets will primarily include Bitcoin holdings and shares of the iShares Bitcoin Trust. It will also hold cash to manage liquidity. The strategy seeks to track Bitcoin price performance while generating premium income. Therefore, the fund will write call options on IBIT shares on an active basis. At times, it may write options tied to ETP indices tracking spot Bitcoin products.

The fund allows in kind creations and redemptions. This approach supports efficient market operations and tax considerations. Coinbase will custody the Bitcoin holdings. Meanwhile, Bank of New York Mellon will custody cash positions. The filing follows an earlier Nasdaq submission under commodity based trust rules. Thus, the process advances a product discussed for months.

The filing clarifies that shares do not equal direct Bitcoin ownership. Instead, investors gain exposure through a regulated security. The income feature distinguishes it from standard spot Bitcoin ETFs. As a result, the product targets investors seeking yield with market exposure.

Market Context and ETF Flow Pressures

The filing coincides with sharp outflows across crypto ETPs. According to CoinShares data, weekly outflows reached $1.73 billion. U.S. listed products accounted for roughly $1.8 billion of that total. Bitcoin ETPs led with $1.09 billion in outflows. Ethereum ETPs followed with $630 million leaving funds.

Analysts attributed the pullback to fading rate cut expectations and weak price momentum. Additionally, disappointment grew as crypto assets lagged the debasement trade. BlackRock’s iShares crypto ETPs saw $951 million in outflows. However, year to date inflows across those funds still stand at $847 million. Therefore, longer term demand remains visible despite short term pressure.

Positioning Against Established Bitcoin ETF Leaders

BlackRock already leads the Bitcoin ETF market by assets. Its existing products hold nearly $70 billion in Bitcoin. Data from DefiLlama supports that figure. Fidelity ranks second with about $17 billion held. The new income focused fund differs from the 2024 spot Bitcoin ETF launch. In October, BlackRock and Fidelity’s spot Bitcoin ETFs achieved a combined $5.5B in trading volume in one day.

The filing also follows a recent spot Bitcoin ETF announcement from Morgan Stanley. Therefore, competition among traditional firms continues to intensify. The covered call approach trades some upside for regular income. This mirrors yield strategies seen in other crypto linked products.

The fund will generate monthly income through option premiums. It will maintain Bitcoin exposure through direct holdings and IBIT shares. The structure reflects growing demand for diversified crypto investment profiles.
