Blackrock advanced its crypto product lineup by filing an amended registration for a bitcoin-focused income exchange-traded fund (ETF). The world’s largest asset manager filed Amendment No. 1 to Form S-1 on March 31 with the U.S. Securities and Exchange Commission (SEC), outlining the Ishares Bitcoin Premium Income ETF strategy and structure. The filing presents a hybrid model that combines bitcoin exposure with options-based income generation.
The filing states:
“The shares are listed and traded on Nasdaq under the ticker symbol ‘BITA.’”
The trust’s assets mainly include bitcoin, along with shares of the Ishares Bitcoin Trust ETF (IBIT) and cash, including income generated from selling call options on IBIT shares and related indices. It is designed to track the overall price performance of bitcoin while also producing additional income through an active strategy of selling call options on IBIT shares.

The sponsor, Ishares Delaware Trust Sponsor LLC, expects all options used by the trust to be listed on U.S. exchanges. These may include standard listed options on IBIT as well as flexible exchange (FLEX) options, which allow customization of strike prices and expiration dates to better manage exposure. If position limits are reached for standard IBIT options, the trust may shift to FLEX options or use standardized options on relevant indices.
The filing details:
“The trust will seek enhanced monthly premium income by writing (selling) monthly covered call options primarily on IBIT shares, and, from time to time, on ETP Indices.”
The options are generally expected to have monthly expiries, though durations may vary based on strategy, and their use introduces risks such as leverage, liquidity constraints, counterparty exposure, and operational challenges that could impact performance. The prospectus also highlights broader risks, including bitcoin volatility, regulatory uncertainty, and reliance on custodians, clearing agents, and market participants, while noting the trust’s status as an emerging growth company with reduced reporting requirements.
