Bitcoin Spot ETFs Witness Historic $3.24 Billion Weekly Surge, Ethereum ETFs Follow Suit

Institutional Inflows Revive Confidence in Bitcoin Spot ETFs

The U.S. Bitcoin (BTC) spot exchange-traded fund (ETF) market has experienced a remarkable resurgence, recording net inflows of $3.24 billion (approximately KRW 4.582 trillion) in just one week. This unprecedented capital injection reflects the growing re-engagement of institutional investors with the digital asset market, signifying a strong comeback for the sector.

Data from SosoValue as of October 3 (Eastern Time) reveals that daily net inflows into Bitcoin spot ETFs reached $985 million (approximately KRW 1.4 trillion), underscoring strong momentum. Cumulatively, the total net inflows for Bitcoin spot ETFs have now exceeded $60 billion, marking a key milestone for the maturing industry.

BlackRock’s iShares Bitcoin Trust Dominates Inflows

Among fund managers, BlackRock’s iShares Bitcoin Trust (IBIT) has continued to solidify its dominance, attracting a staggering $791.55 million (approximately KRW 1.12 trillion) in a single day. This inflow underscores the institutional confidence in BlackRock's ETF as a preferred vehicle for Bitcoin exposure. Fidelity’s Wise Origin Bitcoin Trust (FBTC) came second with $69.58 million (approximately KRW 98.4 billion) in inflows, followed by Grayscale Bitcoin Trust (GBTC), which added $18.29 million (approximately KRW 2.59 billion).

Other prominent players, including Ark Invest and Bitwise, also reported positive momentum, collectively boosting the overall market. Notably, the combined net assets under management (AUM) for all Bitcoin spot ETFs now stand at approximately $164.5 billion (around KRW 232.7 trillion), representing 6.7% of Bitcoin's total market capitalization.

Ethereum Spot ETFs Hit New Inflow Records

While Bitcoin ETFs stole the spotlight, Ethereum (ETH) spot ETFs demonstrated notable strength in parallel. The nine active Ethereum spot ETFs collectively recorded $1.3 billion in net inflows for the week, a figure that sets a new record since their introduction in June. This week-long surge highlights Ethereum's growing appeal among institutional investors, further diversifying interest across the digital asset landscape.

Reports from WuBlockchain underline the broader trend, showcasing how inflows into Ethereum spot ETFs kept pace with Bitcoin’s meteoric week. Between September 29 and October 3, Ethereum funds achieved their highest-ever weekly capital injection, signaling increased acceptance of ETH as a crucial part of institutional portfolios.

Federal Reserve Expectations and Renewed Appetite for Risk Assets

Financial analysts believe the recent influx into Bitcoin and Ethereum ETFs stems from shifting market sentiment around macroeconomic factors. Specifically, expectations that the Federal Reserve could pivot toward rate cuts have reignited institutional interest in riskier assets such as cryptocurrencies.

Flagship funds like BlackRock’s IBIT and Fidelity’s FBTC are not only benefiting from this renewed appetite but also propelling the "financialization" of cryptocurrencies further into the mainstream. This underscores increasing trust in Bitcoin and Ethereum as institutional-grade investment products.

Institutional Momentum Bodes Well for Digital Asset Adoption

The meteoric rise in inflows for Bitcoin and Ethereum spot ETFs signals a broader trend of growing institutional acceptance of cryptocurrencies as legitimate financial instruments. The influx of $3.24 billion into Bitcoin ETFs and $1.3 billion into Ethereum ETFs within just a week highlights increasing confidence in their market potential.

As institutional investors continue to gravitate toward digital assets, the broader cryptocurrency sector could see further integration into traditional investment paradigms. Both Bitcoin and Ethereum, leading the charge, appear poised to solidify their place as indispensable components of modern portfolio strategies.
