The 2020s have already witnessed a seismic shift in investment trends, with traditional finance giants embracing digital assets at an unprecedented pace. Among the most notable developments is the rise of Bitcoin exchange-traded funds (ETFs), which have quickly become some of the fastest-growing financial products of the decade. According to Eric Balchunas, Senior ETF Analyst at Bloomberg, two Bitcoin ETFs—BlackRock’s IBIT and Fidelity’s FBTC—have emerged as top performers in terms of assets under management (AUM), joining an elite group of funds that have surpassed $10 billion in value since their launch.
With roughly 2,000 ETFs introduced since 2020, making the top 10 by AUM is no small feat. What makes IBIT and FBTC stand out is not just their size but also their youth. Unlike most top performers, which are legacy funds from established firms like JP Morgan and Capital Group, these Bitcoin ETFs were launched after the 2022 bear market—a period when many doubted crypto’s staying power.
“Half the list is low-cost legacy active [funds],” Balchunas noted on X (formerly Twitter). “IBIT and FBTC stunning given how young they are.”
This rapid ascent underscores growing institutional confidence in Bitcoin as a legitimate asset class and signals a broader acceptance within mainstream finance.
IBIT’s Momentum Builds with Regulatory Milestone
One key driver behind IBIT’s success has been regulatory progress. In late September, the U.S. Securities and Exchange Commission (SEC) approved options trading for BlackRock’s spot Bitcoin ETF—a significant development that expands investment strategies available to institutional players. Options allow investors to hedge risk or leverage positions, making the ETF more attractive to sophisticated traders and asset managers.

The impact was immediate. On September 28 alone, IBIT recorded over $111 million in net inflows, reflecting strong demand. By October 2, the fund achieved another milestone: $1 billion in daily trading volume. This level of liquidity enhances price stability and reinforces IBIT’s position as the market leader among spot Bitcoin ETFs.
While BlackRock filed a recent amendment to its ETF documentation—sparking speculation about potential structural changes—the overall trajectory remains strongly positive. For now, there are no signs of slowing down.
FBTC Faces Short-Term Outflows Amid Market Volatility
In contrast, Fidelity’s FBTC has experienced a recent setback. October began with a downturn in the broader crypto market—dubbed “Uptober” by some investors expecting gains—leading to significant outflows. On one day alone, FBTC saw $144.67 million exit the fund, marking it as the worst-performing Bitcoin ETF during that period.
This reversal is particularly striking given that just days earlier, FBTC had outpaced IBIT in inflows amid a broader crypto market recovery. The volatility highlights the sensitivity of these new ETFs to market sentiment and macroeconomic conditions.
Despite this short-term dip, FBTC remains a major player with over $10 billion in AUM. Its long-term potential continues to be supported by Fidelity’s strong reputation in retirement and institutional services, as well as its early mover advantage in crypto custody solutions.
Why Bitcoin ETFs Are Reshaping Investment Portfolios
Bitcoin ETFs represent a pivotal bridge between traditional finance and digital assets. They allow investors to gain exposure to Bitcoin without the complexities of self-custody or navigating cryptocurrency exchanges. Instead, they trade like any other stock through conventional brokerage accounts.
This accessibility has fueled widespread adoption, especially among retirement accounts, pension funds, and conservative investors who previously avoided crypto due to operational or security concerns.
Nuno Serafim, Managing Partner at 3 Comma Capital, emphasized that while ETFs don’t mitigate volatility—they’re designed to track underlying asset performance—they play a crucial role in long-term portfolio strategy.
“As passive investment vehicles, the ETFs, by definition, cannot tackle volatility since their focus is to replicate as perfectly as possible the behaviour of the underlying assets. We believe digital assets are strategic and their performance is a long duration story where the main drivers will be use cases and adoption rate. Volatility is an intrinsic feature of long duration assets and that will not change in the foreseeable future.”
His insight underscores a fundamental truth: Bitcoin’s price swings aren’t a flaw—they’re a characteristic of an emerging asset class still in its growth phase.
