BlackRock’s IBIT Spot Bitcoin Exchange-Traded Fund (ETF) has reached a major milestone, surpassing 500,000 BTC (approximately $48 billion) in assets under management (AUM). The achievement comes less than a year after its debut on January 11, making it one of the fastest-growing ETFs in history.
As of November 29, IBIT held 496,854 BTC, according to the fund’s latest disclosures. A single-day net inflow of $338.3 million (approximately 3,526 BTC) on Monday pushed its total holdings to 500,380 BTC, according to data from K33.
Rapid Accumulation and Market Impact
“This is unprecedented growth,” said Vetle Lunde, Head of Research at K33. “BlackRock’s IBIT has now accumulated over 500,000 BTC in just 233 trading days.” Ian Unsworth, co-founder of Kairos Research, highlighted that IBIT’s holdings now represent 2.38% of Bitcoin’s total supply, underscoring its significance in the market.
BlackRock CEO Larry Fink previously described IBIT as the “fastest-growing ETF in the history of ETFs” during an interview in March when the fund surpassed 250,000 BTC. Since then, Bitcoin’s price has surged by 38%, currently trading around $95,321.
U.S. Bitcoin ETFs Approaching Satoshi’s Holdings
U.S. spot Bitcoin ETFs collectively attracted $353.6 million in net inflows on Monday, contributing to a record-breaking $6.6 billion in inflows during November. These ETFs now hold nearly 1.08 million BTC, edging closer to the estimated 1.1 million BTC attributed to Bitcoin’s pseudonymous creator, Satoshi Nakamoto.
Satoshi’s holdings are based on blockchain research identifying early mining patterns, but estimates vary widely. While the most widely accepted figure is around 1.1 million BTC, some researchers suggest it could range between 600,000 BTC and 1.5 million BTC due to uncertainties in early mining activity.
Ethereum ETFs Also See Gains
While Bitcoin ETFs dominate, U.S. spot Ethereum ETFs also recorded $24.2 million in net inflows on Monday, led by BlackRock’s ETHA, which brought in $55.9 million. Ethereum ETFs achieved a record $1.1 billion in net inflows during November.
BlackRock’s remarkable success in the crypto ETF space underscores the growing institutional interest in Bitcoin and highlights the accelerating pace of adoption in regulated financial markets.
