The launch of spot Bitcoin exchange-traded funds (ETFs) marked a pivotal moment in the cryptocurrency market, offering investors a new, regulated way to gain exposure to Bitcoin. In the first year of trading, which began on January 11, 2024, these ETFs saw massive success, with a combined $36.2 billion in net inflows. However, not all Bitcoin ETFs performed equally, with some reaping enormous benefits while others struggled to generate significant investor interest.
Record-Breaking Success: iShares Bitcoin Trust (IBIT)
The clear leader in the spot Bitcoin ETF space has been BlackRock’s iShares Bitcoin Trust (IBIT). Over the past year, IBIT attracted an impressive $38 billion in net inflows, far outpacing its competitors. As of January 19, 2025, IBIT’s assets under management (AUM) reached $52.9 billion, making it the dominant force in this market.
IBIT’s success is nothing short of record-breaking. It reached the $50 billion milestone in just 227 trading days, setting a new benchmark for ETF growth. This achievement shattered the previous record, which had stood for nearly a decade, set by the iShares Core MSCI Emerging Markets ETF (IEMG), which took 1,323 days to reach similar AUM levels.
Not only has IBIT surpassed its peers, but it has also outperformed iShares’ own gold ETF (IAU), which has been a long-standing staple for investors seeking precious metals exposure. Furthermore, IBIT is rapidly closing in on SPDR Gold Shares (GLD), the world’s largest gold ETF, which currently holds about $75 billion in assets. These milestones highlight Bitcoin’s growing institutional acceptance and the role of IBIT in capitalizing on this trend.
Why IBIT Succeeded
Several factors contributed to IBIT’s overwhelming success:
Institutional Backing: As a product from BlackRock, one of the world’s largest asset managers, IBIT garnered significant institutional confidence, which helped drive massive inflows.
Regulatory Approval: Being one of the first Bitcoin ETFs to gain regulatory approval helped instill trust and legitimacy in the product, attracting both retail and institutional investors.
Market Conditions: With Bitcoin’s growing mainstream acceptance and the increasing interest in digital assets, IBIT has tapped into a growing demand for exposure to the cryptocurrency without the complexities of directly holding Bitcoin.
GBTC’s Struggles: Massive Outflows Despite Size
While IBIT has seen remarkable success, Grayscale’s Bitcoin Trust (GBTC) has had a rough year. Despite being one of the longest-standing Bitcoin investment vehicles, GBTC experienced massive outflows, totaling $21 billion over the past year.
There are mixed opinions about GBTC’s performance. On one hand, the fund still maintains its position as the second or third-largest Bitcoin fund, depending on the day. On the other hand, GBTC experienced outflows of $1.6 billion in its first year of trading as a spot Bitcoin ETF, a clear sign that investors were moving their capital elsewhere.
Factors Behind GBTC’s Struggles
Outdated Structure: GBTC existed as a private trust before being restructured into an ETF. This legacy structure has led to a mismatch between its inflows and assets under management (AUM), as well as reduced investor confidence in comparison to newer, more agile funds like IBIT.
Competition: The launch of new Bitcoin ETFs with clearer structures, such as IBIT and others, has drawn investors away from GBTC, especially given the better terms and lower fees offered by these newer ETFs.
Price Volatility: Bitcoin’s notorious volatility has also impacted GBTC, with some investors moving to more established funds that offer lower risk, or opting for funds with more favorable growth trajectories.
Other ETFs: Limited Impact
While IBIT reigned supreme, other Bitcoin ETFs struggled to attract substantial investor interest. Some, such as Fidelity’s Wise Origin Bitcoin Fund (FBTC), managed to garner more than $10 billion in inflows, making it a notable contender. However, it was still far behind IBIT in terms of total assets and overall growth.
Other funds like the Bitwise Bitcoin ETF (BITB) and ARK 21Shares Bitcoin ETF (ARKB) also saw billion-dollar inflows, though none came close to matching IBIT’s $38 billion haul.
Meanwhile, several other Bitcoin ETFs struggled to gain traction, with funds promoted by firms like Franklin (EZBC), Invesco (BTCO), Valkyrie (BRRR), VanEck (HODL), and WisdomTree (BTCW) seeing less than $1 billion in inflows during their first trading year. This highlights the highly competitive nature of the Bitcoin ETF market, where only a few products were able to break through and attract significant investor interest.
Market Impact and the Future of Bitcoin ETFs
The success of spot Bitcoin ETFs, particularly IBIT, is a clear indication of the growing acceptance of cryptocurrencies in traditional financial markets. The ability to buy Bitcoin through an ETF simplifies the investment process and provides a regulated, accessible product for institutional and retail investors alike.
Looking ahead, we can expect more competition in the Bitcoin ETF space, as well as potential innovations in ETF structures and cryptocurrency offerings. The outflows from GBTC, in particular, may signal a shift toward more modern investment vehicles with better terms and liquidity, while funds like IBIT will continue to set the pace for future growth.
Conclusion
The first year of spot Bitcoin ETFs has been a major success, marked by record-breaking inflows and increased institutional participation. BlackRock’s IBIT has emerged as the clear leader, with impressive growth that has left its competitors far behind. However, Grayscale’s GBTC has seen significant outflows, while several other funds struggled to make a meaningful impact. As Bitcoin ETFs continue to evolve, investors will need to stay informed about market trends, regulatory changes, and product innovations to make the most of this rapidly growing sector.
