U.S.-listed Bitcoin and Ethereum exchange-traded funds (ETFs) recorded a strong rebound on Thursday, September 18, with combined inflows of $376 million. The surge came just one day after the products experienced significant outflows, underscoring the volatility and fast-changing sentiment in crypto-linked financial instruments.

Bitcoin ETFs drew $163.03 million in net inflows across seven funds. Fidelity’s FBTC led the field with $97.35 million, while Ark 21Shares’ ARKB followed with $25 million. Bitwise’s BITB added $12.78 million, and the Grayscale Bitcoin Mini Trust contributed $10.93 million. Additional gains came from Franklin Templeton’s EZBC ($6.8 million), VanEck’s HODL ($6.65 million), and Invesco’s BTCO ($3.51 million). Importantly, no Bitcoin ETFs recorded outflows for the day.

Ethereum ETFs outpaced Bitcoin products, bringing in $213 million in net inflows. The strength of Ethereum’s demand reflected a sharp reversal from earlier in the week, when both Bitcoin and Ethereum products had lost capital.

Trading volume across all crypto ETFs on Thursday reached $3.45 billion. Total net assets of these funds climbed to $155.05 billion, showing an increase in value alongside the renewed inflows.

Market Context

The turnaround followed Wednesday’s losses, when investors pulled money out of both Bitcoin and Ethereum ETFs. That session had raised questions about whether enthusiasm for crypto ETFs was weakening after weeks of steady gains. By Thursday, however, capital returned in force, reversing the previous day’s trend.

The inflows into Fidelity’s FBTC and Ark 21Shares’ ARKB demonstrated continued investor preference for larger and more liquid products. Smaller issuers, including Franklin Templeton, VanEck, and Invesco, also posted positive results but on a smaller scale.

Ethereum’s lead in Thursday’s inflows marked a notable development in the distribution of investor demand. The $213 million net addition was the single largest daily inflow for Ethereum-linked funds in recent weeks, pushing them ahead of Bitcoin products for the day.

Structural Details

ETFs function as regulated vehicles that track the spot price of cryptocurrencies, allowing investors to gain exposure without directly holding the underlying assets. Inflows represent capital entering these funds, which increases their holdings of Bitcoin or Ethereum in proportion to investor demand.

Data from Thursday showed both asset classes attracting fresh investment simultaneously, with no offsetting withdrawals. This absence of outflows distinguished the day from earlier sessions, where inflows into one product group often coincided with losses in another.

The $3.45 billion trading volume indicated active participation across markets. High daily turnover in these ETFs reflects both speculative and institutional activity, as the products serve as tools for portfolio rebalancing as well as short-term trading.

Day’s Significance

The net inflows of $376 million underscored the scale of Thursday’s reversal. For Bitcoin ETFs, the $163 million addition was their strongest daily inflow in over a week. For Ethereum ETFs, the $213 million figure marked a clear rebound from prior losses, highlighting the scale of investor interest.

With both categories in positive territory, total assets under management for U.S.-listed crypto ETFs closed the day at $155.05 billion. The increase in assets aligned with both market price stability and new capital additions.
