Bitcoin ETFs Attract $602 Million Net Inflow Led by Fidelity

Key Insights:

• Bitcoin ETFs attracted $602 million in net inflows on July 3.
• Fidelity’s FBTC ETF led with a $237 million net inflow.
• Ethereum ETFs saw $149 million inflows, with Grayscale facing losses.

Bitcoin exchange-traded funds (ETFs) posted a combined net inflow of $602 million on July 3, 2025, according to data from SoSoValue.

The strong inflows reflected surging institutional and retail interest in regulated Bitcoin (BTC) investment products.

Fidelity and BlackRock Dominate Bitcoin ETFs Flows

Fidelity’s FBTC led all U.S. Bitcoin ETFs with a $237 million net inflow on the day, bringing its historical total to $12.209 billion.

The ETF has benefited from Fidelity’s institutional reach and early positioning in the crypto ETF race.

Other thematic launches preceded FBTC, but it now stands as a core Bitcoin allocation vehicle for large funds.

BlackRock’s IBIT ETF followed closely, with $225 million in inflows, pushing its cumulative net inflows to $52.646 billion.

Launched in Jan. 2024, IBIT became the fastest ETF to reach $2 billion in inflows, achieving that milestone within days.

By mid-2025, IBIT had surpassed $50 billion in assets under management (AUM), becoming one of the most dominant Bitcoin ETF products in the U.S.

While IBIT and FBTC led, smaller ETFs also contributed to the overall growth.

Despite brief outflow days, the long-term trend shows sustained demand for Bitcoin-based regulated products.

Ethereum ETFs Also See Positive Inflows

Besides Bitcoin, Ethereum ETFs also contributed to big inflows on July 3. The total net inflow of $149 million into spot Ethereum ETFs cannot be treated uniformly across funds, as there was a discrepancy. The ETHE ETF of Grayscale recorded trash net outflow of $5.35 million compared to other Ethereum-based ETFs with positive inflows.

News submission could be a minor setback to Grayscale ETHE, but the situation appears to favor the Ethereum ETF. Continuous inflows could push the Ethereum network to become a centralized transaction basis in the decentralized finance (DeFi) movement.

Total Bitcoin ETFs Market Value Climbs to $137.6 Billion

The total market valuation of U.S.-listed spot Bitcoin ETFs has climbed to $137.6 billion, representing approximately 6.29% of Bitcoin’s total circulating market capitalization.

Cumulative net inflows across all Bitcoin ETFs have now surpassed $49.64 billion, reaffirming their long-term role in capitalizing institutional crypto interest.

The data confirms that regulated products are now a core feature of the Bitcoin investment thesis, offering safe, liquid access for both retail and institutional allocators.

Implications: BTC and ETH ETFs Cement Their Role in U.S. Capital Markets

As spot ETF inflows grow, Bitcoin is evolving from a speculative asset to a legitimate part of diversified institutional portfolios.

ETF dominance by Fidelity and BlackRock illustrates how traditional asset managers are shaping the crypto investment landscape.

Meanwhile, despite the outflow from Grayscale’s ETHE, ETH ETF inflows point to Ethereum’s growing appeal as a programmable financial layer.

With ongoing demand for compliant exposure to digital assets, regulated products like FBTC, IBIT, and ETH-based ETFs are expected to continue gaining traction, especially in bull market cycles.

Data from SoSoValue and Wu Blockchain supports the broader narrative: U.S. capital markets are becoming increasingly intertwined with blockchain-based assets, with ETFs serving as the onramp.

The sharp inflows into Bitcoin and Ethereum ETFs on July 3 signal that institutional demand for regulated crypto exposure remains intact. Fidelity’s FBTC and BlackRock’s IBIT continue to lead the market, while ETH-based funds have started to see steady capital allocation despite mixed performance from legacy issuers like Grayscale.

As total ETF-managed Bitcoin assets near $140 billion, the role of traditional financial institutions in crypto markets is becoming more defined. With volatility expected to persist, ETF flows will remain a critical gauge of investor sentiment and risk appetite across both Bitcoin and Ethereum markets.
