What is the iShares Bitcoin Trust ETF (IBIT)?

iShares Bitcoin Trust ETF (IBIT) is a spot Bitcoin exchange‑traded fund managed by BlackRock that tracks Bitcoin’s price by holding bitcoin or bitcoin exposures. It charges a 0.25% management fee, has become BlackRock’s most profitable ETF, and is approaching $100 billion in net assets.

How much revenue has IBIT generated for BlackRock?

Over the past 12 months IBIT generated about $245 million in management fees, outpacing long‑established funds like IWF and EFA by roughly $25 million. Fee revenue scales with assets under management and Bitcoin price movements.

Why is IBIT growing so quickly?

IBIT’s growth is driven by large institutional and retail flows into spot Bitcoin ETFs, favorable regulatory clarity, and strong investor appetite for direct Bitcoin exposure within a familiar ETF wrapper. BlackRock’s distribution reach accelerated adoption compared with earlier crypto funds.

How close is IBIT to $100 billion and why does it matter?

IBIT reached $97.8 billion in net assets in 435 days — a speed record relative to legacy funds such as Vanguard’s VOO, which took about 2,011 days to cross $100 billion. Hitting $100 billion would mark an ETF milestone and further cement spot Bitcoin ETFs as mainstream allocation vehicles.

What new Bitcoin products is BlackRock exploring?

BlackRock filed to register a Delaware trust company for a proposed Bitcoin Premium Income ETF that would sell covered call options on Bitcoin futures to collect premiums and produce yield. This approach offers income but reduces upside participation compared with IBIT’s spot exposure.

Industry commentary (Eric Balchunas), market inflows, and filings indicate BlackRock plans additional Bitcoin and Ether products while avoiding broad altcoin ETF pushes for now. The U.S. Securities and Exchange Commission has paused reviews on some crypto ETF filings pending federal actions.
