When the U.S. Securities and Exchange Commission approved the first spot Bitcoin ETFs back in January 2024, many doubted they’d move the needle.
Less than 18 months later, BlackRock’s iShares Bitcoin Trust (IBIT) has officially surpassed $70 billion in assets under management, making it the fastest-growing exchange-traded funds (ETFs) in history.
It took IBIT just 341 trading days to hit this milestone. That’s five times faster than the SPDR Gold Trust (GLD), which took 1,691 days to reach the same threshold. Even the S&P 500 ETF (VOO) needed 1,701 days to cross the $70 billion mark.
According to daily net flows tracked by Farside Investors, across 11 Bitcoin spot ETFs from May 23 to June 11, IBIT alone brought in over 49,000 BTC worth of inflows, even as rivals like Grayscale’s GBTC saw outflows of over 23,000 BTC in the same period.
The net flows during this stretch total over 45,000 BTC, equivalent to roughly $5 billion in new exposure.
On June 10 alone, IBIT saw another 336.7 BTC in inflows, a signal that institutional demand remains strong even as Bitcoin flirts with all-time highs near $110,000.
The rise of Bitcoin ETFs has triggered what some analysts are calling the “institutionalization of crypto.” Once regarded as a fringe asset class, Bitcoin is now included in wealth portfolios, pension funds, and even bank-backed investment products. BlackRock, Fidelity, and Franklin Templeton—all household names in finance—are now routinely managing crypto exposure for clients.
The implications go beyond Bitcoin. Ethereum spot ETFs are currently being reviewed by the SEC, with a wave of filings from the likes of VanEck, ARK, and Invesco already in motion. Meanwhile, niche products are emerging: Ethereum staking ETFs, multi-asset crypto index funds, and even proposals for Solana, XRP, and other altcoin-based ETFs.
So what changed?
The SEC’s spot ETF approval was the final stamp of legitimacy, backed by trusted custodians, transparent pricing via CME and Coinbase benchmarks, and daily liquidity.
Bitcoin is still volatile, macro conditions could shake investor confidence, and regulatory headwinds haven’t disappeared. But for now, the flows are clear. Money is moving in. And fast.
