BlackRock’s iShares Bitcoin Trust (IBIT) has attained a new milestone by becoming the largest known Bitcoin custodian. IBIT now holds approximately 781,160 BTC, overtaking both Coinbase and Binance as of August 2025.
The event highlights BlackRock Inc.’s strategic importance in institutional cryptocurrency markets. Larry Fink, the company’s CEO, has transitioned from skeptic to advocate for regulated crypto via ETFs, although no direct comments from him have surfaced regarding this development.
The surge in IBIT’s Bitcoin holdings reflects a broader shift from retail exchanges to institutional products. This move may significantly influence Bitcoin’s market supply dynamics and liquidity conditions.
Financial implications include Bitcoin ETFs representing a notable portion of the total circulating supply. The migration of liquidity from exchanges to ETFs is evident, showing a sustained demand for regulated implementation.
The evolving ETF landscape underscores a larger institutional role in influencing Bitcoin’s price stability. This trend will likely persist, given the current framework supporting continuous institutional inflows. Despite BlackRock’s lack of public comments, the impact is widely discussed on industry forums.
“With IBIT surpassing Coinbase and Binance, we are witnessing a pivotal moment where institutional ETF-led custody drives Bitcoin market structure.”
Market observers note a major liquidity movement as Bitcoins are increasingly placed in regulated environments. This may impact price discovery and long-term investor strategies, marking a significant shift in cryptocurrency market dynamics.
