BlackRock, the world’s largest asset manager, has filed in Delaware for a new Bitcoin Premium Income ETF. The fund is designed to generate yield from Bitcoin-related premiums, marking another step in the firm’s growing commitment to digital assets.

The filing comes after the success of BlackRock’s spot Bitcoin ETF (IBIT), which has surged to $90 billion in assets under management by September 2025. IBIT now controls around 60% of the U.S. Bitcoin ETF market, underscoring BlackRock’s dominance in the sector. Its Bitcoin and Ethereum ETFs have already generated $260 million in annual revenue in under two years.

The new income-focused product aims to attract investors looking for Bitcoin exposure with added yield potential. By offering a premium income structure, it provides a differentiated strategy compared to IBIT, which directly tracks Bitcoin’s price. BlackRock has also been gradually increasing crypto exposure across its model portfolios, typically allocating 1%–2% to digital assets.
