U.S. Bitcoin ETFs See Near-$1 Billion Inflow, Led by BlackRock; Ethereum ETF Inflows Cool

On October 3, 2025, U.S. spot Bitcoin Exchange-Traded Funds (ETFs) recorded a massive total inflow of $985.08 million, highlighting sustained and intense institutional demand for Bitcoin. This massive injection of capital pushed the total trading volume for Bitcoin ETFs to $7.52 billion, with total net assets reaching $164.50 billion.

Bitcoin ETF Inflows Dominated by BlackRock

The leader of the session was BlackRock’s iShares Bitcoin Trust (IBIT), which single-handedly dominated the market with an inflow of $791.55 million.

Other top performers included:

• Fidelity FBTC: $69.58 million
• Ark & 21Shares (ARKB): $35.48 million
• VanEck HODL: $26.04 million
• Bitwise BITB: $24.03 million

Even Grayscale’s GBTC posted a small gain of $18.29 million, contributing to the overall positive flow.

Ethereum ETF Inflows Decline

In contrast to Bitcoin, institutional appetite for Ethereum ETFs showed a short-term cooling, with total inflows dropping to $233.55 million. Only four out of nine Ethereum ETFs posted positive gains.

• BlackRock ETHA was the clear leader, dominating the session with $206.71 million in inflows.
• The total net assets for Ethereum ETFs reached $30.57 billion.

Despite the reduced inflows, Ethereum's total trading volume remained strong at $2.28 billion.

Market Context: Bitcoin Nears All-Time High

The massive ETF inflows come as Bitcoin trades around $122,777, standing just 1.1% shy of its all-time high. Its market capitalization surged to $2.448 trillion, reflecting strong institutional confidence. Ethereum also saw a price increase to $4,502.39, supported by robust trading activity.
