Bitcoin and Ether ETFs Record Second-Biggest Daily Inflows in History

Massive Capital Flows Into Crypto ETFs

Bitcoin and Ether exchange-traded funds experienced their second-largest daily inflows since launch on Thursday, demonstrating continued institutional appetite for cryptocurrency exposure through regulated investment vehicles.

Bitcoin ETFs Attract $1.17 Billion in Single Day

US spot Bitcoin exchange-traded funds recorded total inflows of $1.17 billion on Thursday, marking a significant milestone for cryptocurrency investment products. BlackRock's iShares Bitcoin Trust ETF led the charge with $448 million in inflows, while Fidelity's Wise Origin Bitcoin Fund contributed $324 million to the daily total.

These substantial inflows coincided with Bitcoin reaching new all-time highs above $113,800, as the cryptocurrency continued its upward trajectory into Friday trading sessions. The strong performance reflects growing institutional confidence in Bitcoin as a legitimate asset class.

Historic Context for Bitcoin ETF Performance

The $1.17 billion inflow figure represents the second-highest daily total since Bitcoin ETFs launched. The record remains with the $1.37 billion recorded on November 7, 2024, coinciding with Donald Trump's victory in the US presidential election.

Ether ETFs See Record-Breaking $383 Million Inflows

Ether spot ETFs witnessed total net inflows of $383.1 million on Thursday, also achieving their second-highest net inflow day in the funds' operating history. This performance demonstrates that institutional interest extends beyond Bitcoin to include Ethereum-based investment products.

BlackRock's iShares Ethereum Trust ETF dominated Ether ETF flows, capturing $300.9 million in net inflows. This figure represents the highest single-day inflow on record for the specific fund, highlighting BlackRock's market leadership in cryptocurrency ETF products.

Institutional Adoption Challenges Persist

Despite record-breaking inflows, cryptocurrency ETFs face ongoing adoption hurdles within traditional financial advisory channels. Industry experts note that major platforms including Vanguard continue restricting access to Bitcoin and Ether spot ETFs for their clients.

This gatekeeping approach by established financial institutions may be limiting even greater capital flows into cryptocurrency ETFs, suggesting potential for future growth as adoption barriers decrease.

ETF Demand Exceeds Cryptocurrency Production

Current ETF inflows significantly outpace the natural issuance rates of both Bitcoin and Ether, creating supply-demand dynamics that could influence future price movements.

Ethereum Supply Dynamics

Ethereum's net issuance stood at 2,110 ETH over the past 24 hours, equivalent to approximately $6.33 million in value. This production rate pales in comparison to the $383.1 million in Thursday's Ether ETF inflows, indicating that ETF demand far exceeds new supply creation.

Bitcoin Market Absorption

Bitcoin ETFs have purchased $28.22 billion worth of Bitcoin in 2025, while Bitcoin miners have produced only $7.85 billion in new issuance during the same period. This three-to-one ratio demonstrates how ETF demand substantially exceeds natural Bitcoin production rates.

Market Implications for Cryptocurrency ETFs

The record-breaking inflow figures suggest several important market trends developing within cryptocurrency investment products:

Strong institutional demand continues driving capital into both Bitcoin and Ether ETFs, with BlackRock emerging as a dominant force across both asset classes. The significant gap between ETF demand and cryptocurrency production rates could create upward pressure on underlying asset prices.

Traditional financial institutions' gradual acceptance of cryptocurrency ETFs may accelerate as these products demonstrate sustained investor interest and regulatory compliance. However, complete mainstream adoption remains limited by gatekeeping practices at major investment platforms.

Future Outlook for Crypto ETFs

The success of Bitcoin and Ether ETFs in attracting institutional capital represents a maturation of cryptocurrency markets. As these products continue setting inflow records and demonstrating sustained investor interest, they may pave the way for broader cryptocurrency adoption within traditional portfolio management strategies.

The substantial demand exceeding production rates for both Bitcoin and Ether suggests that ETF structures are effectively channeling institutional capital into cryptocurrency markets, potentially influencing long-term price dynamics and market development.
