- Strong institutional demand continues to drive Bitcoin’s price surge, with IBIT playing a key role in mainstream adoption.
BlackRock’s iShares Bitcoin Trust (IBIT) has shattered records and sent shockwaves through the investment world by becoming the fastest exchange-traded fund (ETF) to reach $70 billion in assets under management (AUM). In just 341 trading days, this Bitcoin-focused ETF has outpaced legendary funds like the SPDR Gold Shares ETF (GLD), which took over four years to hit the same mark.
Record-Breaking Growth in Lightning Speed
Bloomberg ETF analyst Eric Balchunas highlighted IBIT’s rapid ascent, noting it blew past $70 billion AUM on June 9, 2025. According to BlackRock’s official data, the fund’s AUM now stands at $71.8 billion, holding a staggering 661,457 BTC. This achievement is unprecedented — the previous speed record was held by GLD, which took 1,691 days to reach $70 billion, making IBIT’s rise nearly five times faster

Institutional Investors Leading the Charge
Unlike the retail market, which has been cautious, institutional investors have eagerly jumped on board, fueling the surge in IBIT’s assets. Since early April, the fund has seen only three days of outflows, aggressively accumulating Bitcoin. When BlackRock launched IBIT, Bitcoin was trading around $30,000 amid lingering skepticism after the FTX collapse. Today, Bitcoin is trading near $110,000 — a sevenfold gain and far outpacing the S&P 500’s return in the same period.
ETF Store President Nate Geraci emphasized the broader trend: there are now eleven spot Bitcoin ETFs, collectively managing nearly $125 billion in assets. These figures underscore the growing legitimacy and massive institutional appetite for Bitcoin.
Bitcoin Price and ETF Flows: A Positive Feedback Loop
June 9 also marked a shift in investor behavior, as ETF flows turned positive with a net $386 million inflow across the eleven Bitcoin ETFs. BlackRock itself saw a healthy $121 million inflow, trailing Fidelity’s $173 million. The rebound in ETF demand coincided with a fresh Bitcoin price surge, hitting an intraday high above $110,000 during Asian trading hours.
Some experts speculate BlackRock’s Bitcoin holdings could surpass even the largest known Bitcoin stash — that of the pseudonymous creator, Satoshi Nakamoto, who holds roughly 1.1 million coins — by mid-2026 if this growth trajectory continues.
What’s Next for Bitcoin and IBIT?
With Bitcoin just 2% shy of a new all-time high, BlackRock’s IBIT is proving that institutional demand remains a powerful driver for the cryptocurrency market. As Bitcoin edges closer to new heights, BlackRock’s ETF is not just a record-setter but also a bellwether for crypto’s growing acceptance in mainstream finance.
For investors, this milestone signals a new era — one where Bitcoin ETFs are not only competitive with traditional assets but are also setting the pace for future financial innovation.
